FIELD OF THE INVENTION

[002] This invention is directed to novel indole, indazole, benzimidazole, benzotriazole, indoline, quinolone, isoquinoline, and carbazole selective androgen receptor degrader (SARD) compounds including A-ring heterocyles, pharmaceutical compositions and uses thereof in treating hyperproliferations of the prostate including pre-malignancies and benign prostatic hypertrophy, prostate cancer, advanced prostate cancer, castration resistant prostate cancer, other AR-expressing cancers, androgenic alopecia or other hyper androgenic dermal diseases, Kennedy’s disease, amyotrophic lateral sclerosis (ALS), abdominal aortic aneurysm (AAA), and uterine fibroids, and to methods for reducing the levels (through degradation) and/or activity (through inhibition) of any androgen receptor including androgen receptor-full length (AR-FL) including pathogenic and/or resistance mutations, AR-splice variants (AR-SV), and pathogenic polyglutamine (polyQ) polymorphisms of AR in a subject. BACKGROUND OF THE INVENTION

[003] Prostate cancer (PCa) is one of the most frequently diagnosed noncutaneous cancers among men in the US and is the second most common cause of cancer deaths with more than 200,000 new cases and over 30,000 deaths each year in the United States. PCa therapeutics market is growing at an annual rate of 15-20% globally.

[004] Androgen-deprivation therapy (ADT) is the standard of treatment for advanced PCa. Patients with advanced prostate cancer undergo ADT, either by luteinizing hormone releasing hormone (LHRH) agonists, LHRH antagonists or by bilateral orchidectomy. Despite initial response to ADT, disease progression is inevitable and the cancer emerges as castration-resistant prostate cancer (CRPC). Up to 30% of patients with prostate cancer that undergo primary treatment by radiation or surgery will develop metastatic disease within 10 years of the primary treatment. Approximately 50,000 patients a year will develop metastatic disease, which is termed metastatic CRPC (mCRPC).

[005] Patients with CRPC have a median survival of 12-18 months. Though castration-resistant, CRPC is still dependent on the androgen receptor (AR) signaling axis for continued growth. The primary reason for CRPC re-emergence is re-activation of AR by alternate mechanisms such as 1) intracrine androgen synthesis, 2) AR splice variants (AR-SV), e.g., that lack ligand binding domain (LBD), 3) AR-LBD mutations with potential to resist AR antagonists (i.e., mutants that are not sensitive to inhibition by AR antagonists, and in some cases AR antagonists act as agonists of the AR bearing these LBD mutations); and 4) amplications of the AR gene within the tumor.

[006] A critical barrier to progress in treating CRPC is that AR signaling inhibitors such as enzalutamide, flutamide, bicalutamide, and abiraterone, acting through the LBD, fail to inhibit growth driven by the N-terminal domain (NTD)-dependent constitutively active AR-SV. Recent high-impact clinical trials with enzalutamide and abiraterone in CRPC patients demonstrated that 0% of AR-V7 (the predominant AR-SV) expressing patients responded to either of the treatments, indicating the requirement for next generation AR antagonists that target AR-SVs. In addition, a significant number of CRPC patients are becoming refractory to abiraterone or enzalutamide, emphasizing the need for next generation AR antagonists.

[007] Current evidences demonstrate that CRPC growth is dependent on constitutively active AR including AR-SV’s that lack the LBD such as AR-V7 and therefore cannot be inhibited by conve

from the AR LBD provides alternate strategies to manage CRPC.

[008] Herein the NTD is biophysically characterized to interact with the SARDs of this invention via fluorescence polarization (FP), surface plasmon resonance (SPR), and NMR (Example 12). Biochemical evidence also supports the SARDs of this invention binding to a domain other than the LBD. E.g., SARDs of this invention degrade AR-SV in D567es cells lacking the expression of any AR containing the LBD (Example 7). Further, the R- and S-isomers of the SARDs of this invention possess equipotent SARD activity despite demonstrated differences in the binding and inhibition of androgen-dependent transactivation via the LBD (Example 7, Figure 42D). The report of SARD activity mediated through the NTD of AR is an unprecedented observation that may help explanation the prodigious AR antagonism profiles seen with the SARDs of this invention.

[009] Molecules that degrade the AR prevent any inadvertent AR activation through growth factors or signaling pathways, or promiscuous ligand-dependent AR activation. In addition, molecules that inhibit the constitutive activation of AR-SVs are extremely important to provide extended benefit to CRPC patients.

[0010] Currently only a few chemotypes are known to degrade AR which include the SARDs AZD- 3514, ARN-509 and ASC-J9. However, these molecules degrade AR indirectly at much higher concentrations than their binding coefficient and they fail to degrade the AR-SVs that have become in recent years the primary reason for resurgence of treatment-resistant CRPC.

[0011] This invention describes novel AR antagonists with unique pharmacology that strongly (high potency and efficacy) and selectively bind AR (better than known antagonists), antagonize AR, and degrade AR full length (AR-FL) and AR-SV. Selective androgen receptor degrader (SARD) compounds possess dual degradation and AR-SV inhibitory functions and hence are distinct from any available CRPC therapeutics. These novel selective androgen receptor degrader (SARD) compounds inhibit the growth of PCa cells and tumors that are dependent on AR-FL and AR-SV for proliferation.

[0012] SARDs have the potential to evolve as new therapeutics to treat CRPCs that are untreatable with any other antagonists. This unique property of degrading AR-SV has extremely important health consequences for prostate cancer. Till date only one synthetic molecule (EPI-001) and some marine natural products such as sinkotamides and glycerol ether Napthetenone B, are reported to bind to AR- NTD and inhibit AR function and PCa cell growth, albeit at lower affinity and it has an inability to degrad

ligand independent) AR activity.

[0013] The positive correlation between AR and PCa and the lack of a fail-safe AR antagonist, emphasizes the need for molecules that inhibit AR function through novel or alternate mechanisms and/or binding sites, and that can elicit antagonistic activities within an altered cellular environment.

[0014] Although traditional antiandrogens such as enzalutamide, bicalutamide and flutamide and androgen deprivation therapies (ADT) were approved for use in prostate cancer, there is significant evidence that antiandrogens could also be used in a variety of other hormonal dependent and hormone independent cancers. For example, antiandrogens have been tested in breast cancer (enzalutamide; Breast Cancer Res. (2014) 16(1): R7), non-small cell lung cancer (shRNAi AR), renal cell carcinoma (ASC-J9), partial androgen insensitivity syndrome (PAIS) associated malignancies such as gonadal tumors and seminoma, advanced pancreatic cancer (World J. Gastroenterology 20(29):9229), cancer of the ovary, fallopian tubes, or peritoneum, cancer of the salivary gland (Head and Neck (2016) 38: 724-731; ADT was tested in AR-expressing recurrent/metastatic salivary gland cancers and was confirmed to have benefit on progression free survival and overall survival endpoints), bladder cancer (Oncotarget 6 (30): 29860-29876; Int J. Endocrinol (2015), Article ID 384860), pancreatic cancer, lymphoma (including mantle cell), and hepatocellular carcinoma. Use of a more potent antiandrogen such as a SARD in these cancers may treat the progression of these and other cancers. Many hormonal and non-hormonal cancers may benefit from SARD treatment such as breast cancer, testicular cancer, cancers associated with partial androgen insensitivity syndromes (PAIS) such as gonadal tumors and seminoma, uterine cancer, ovarian cancer, cancer of the fallopian tubes or peritoneum, salivary gland cancer, bladder cancer, urogenital cancer, brain cancer, skin cancer, lymphoma, mantle cell lymphoma, liver cancer, hepatocellular carcinoma, renal cancer, renal cell carcinoma, osteosarcoma, pancreatic cancer, endometrial cancer, lung cancer, non-small cell lung cancer (NSCLC), gastric cancer, colon cancer, perianal adenoma, or central nervous system cancer.

[0015] Traditional antiandrogens such as bicalutamide and flutamide were approved for use in prostate cancer. Subsequent studies have demonstrated the utility of antiandrogens (e.g., flutamide, spironolactone, cyproterone acetate, finasteride and chlormadinone acetate) in androgen-dependent dermatological conditions such as androgenic alopecia (male pattern baldness), acne vulgaris, and hirsutism. Prepubertal castration prevents sebum production and androgenic alopecia but this can be reversed by use of testosterone, suggesting its androgen-dependence. [0016]

shortened may augment AR transactivation (i.e., hyperandrogenism). It has been found that shortened polyQ polymorphisms are more common in people with alopecia, hirsutism, and acne. Classic antiandrogens are undesirable for these purposes because they are ineffective through dermal dosing and their long-term systemic use raises the risks of untoward sexual effects such as gynecomastia and impotence. Further, similar to CRPC discussed above, inhibition of ligand-dependent AR activity alone may not be sufficient as AR can be activated by various cellular factors other than the endogeneous androgens testosterone (T) and dihydrotestosterone (DHT), such as growth factors, kinases, co-activator overexpression and/or promiscuous activation by other hormones (e.g., estrogens or glucocorticoids). Consequently, blocking the binding of T and DHT to AR with a classical antiandrogen may not be sufficient to have the desired efficacy.

[0017] An emerging concept is the topical application of a SARD to destroy the AR local to the affected areas of the skin or other tissue(s) without exerting any systemic antiandrogenism. For this use, a SARD that does not penetrate the skin or is rapidly metabolized would be preferrable.

[0018] Supporting this approach is the observation that cutaneous wound healing has been demonstrated to be suppressed by androgens. Castration of mice accelerates cutaneous wound healing while attenuating the inflammation in the wounds. The negative correlation between androgen levels and cutaneous healing and inflammation, in part, explains another mechanism by which high levels of endogenous androgens exacerbate hyperandrogenic dermatological conditions such those described herein. Further, it provides a rationale for the treatment of wounds such as diabetic ulcers or even trauma, or skin disorders with an inflammatory component such as acne or psoriasis, with a topical SARD.

[0019] Androgenic alopecia occurs in ~50% of Caucasian males by midlife and up to 90% by 80 years old. Minoxidil (a topical vasodilator) and finasteride (a systemic 5-alpha reductase type II inhibitor) are FDA approved for alopecia but require 4-12 months of treatment to produce a therapeutic effect and only arrest hair loss in most with mild to moderate hair regrowth in 30-60%. Since currently available treatments have slow and limited efficacy that vary widely between individuals, and produce unwanted sexual side effects, it is important to find a novel approach to treat androgenic alopecia and other hyperandrogenic dermatologic diseases.

[0020] Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. Patients with ALS are characterized by extended AR polyglutamine repeats. Riluzole is an available drug for ALS treatm

the survival of ALS patients. Transgenic animals of ALS were shown to survive longer upon castration and reduction in AR levels compared to castration + nandrolone (agonist) supplementation. Castration reduces the AR level, which may be the reason for extended survival.

[0021] Uterine fibroids are common reproductive-age benign tumors that contribute to severe morbidity and infertility. Cumulative incidence is 4 times higher in Africian-Americans compared to Caucasians and constitutes a major health disparity challenge. Fibroids are the leading indication for hysterectomy and their management averages $21 billion annually in the US. No long term minimally invasive therapies exist. Thus, promising drug therapies, with novel chemistry and pharmacological approaches are needed to improve clinical efficacy. Androgens promote uterine proliferation. Higher testosterone levels increase the risk of uterine fibroids. Treatment of uterine fibroids with SARDs would help prevent or treat uterine fibroids.

[0022] An abdominal aortic aneurysm (AAA) is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky. AR blockade (pharmacologic or genetic) reduces AAA. Davis et al. (Davis JP, Salmon M, Pope NH, Lu G, Su G, Meher A, Ailawadi G, Upchurch GR Jr. J Vasc Surg (2016) 63(6):1602-1612) showed that flutamide (50 mg/kg) or ketoconazole (150 mg/kg) attenuated porcine pancreatic elastase (0.35 U/mL) induced AAA by 84.2% and 91.5% compared to vehicle (121%). Further AR -/- mice showed attenuated AAA growth (64.4%) compared to wildtype (both treated with elastase). Correspondingly, administration of a SARD to a patient suffering from an AAA may help reverse, treat or delay progression of AAA to the point where surgery is needed.

[0023] X-linked spinal-bulbar muscular atrophy (SBMA– also known as Kennedy's disease) is a muscular atrophy that arises from a defect in the androgen receptor gene on the X chromosome. Proximal limb and bulbar muscle weakness results in physical limitations including dependence on a wheelchair in some cases. The mutation results in a protracted polyglutamine tract added to the N- termin

polyQ AR by endogeneous androgens (testosterone and DHT) results in unfolding and nuclear translocation of the mutant androgen receptor. These steps are required for pathogenesis and result in partial loss of the transactivation function (i.e., an androgen insensitivity) and a poorly understood neuromuscular degeneration. Currently there are no disease-modifying treatments but rather only symptom directed treatments. Efforts to target the polyQ AR of Kennedy’s disease as the proximal mediator of toxicity by harnessing cellular machinery to promote its degradation, i.e., through the use of a SARD, hold promise for therapeutic intervention. Selective androgen receptor degraders such as those reported herein bind to and degrade a variety of androgen receptors (full length, splice variant, antiandrogen resistance mutants, and are likely to degrade polyQ AR polymorphisms as well), indicating that they are promising leads for treatment of SBMA.

[0024] Here we describe indole, indazole, benzimidazole, benzotriazole, indoline, quinolone, isoquinoline, and carbazole SARDs that bind to LBD and an alternate binding and degradation domain (BDD; located outside the LBD in the NTD), antagonize AR, and degrade AR thereby blocking ligand-dependent and ligand-independent AR activities. This novel mechanism produces improved efficacy when dosed systemically (e.g., for prostate cancer) or topically (e.g., for dermatological diseases). SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:

[0045] Figures 1A-1C present inhibition of AR transactivation for the SARD compounds: (Figure 1A) 14, 18, and 20; (Figure 1B) 11 and 12; and (Figure 1C) 11, 23 and 27; of this invention. (Example 5)

[0046] Figure 2A demonstrates degradation in LNCaP cells using SARD compounds of this invention (11 and 20): LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free conditions for 3 days. The cells were treated as indicated in the figure, harvested, protein extracted, and Western blotted for AR. Figure 2B presents the effect of AR antagonists and SARD 11 on LNCaP cell growth: LNCaP cells were plated in 96 well plates at 10,000 cells/well in RPMI + 1% csFBS without phenol red. Cells were treated as indicated in the figure in combination with 0.1 nM R1881 for 6 days with medium change on day 3. At the end of 6 days, the cells were fixed and stained with sulphorhodamine blue stain. (Example 7)

[0047] Figure 3 presents AR-V7 degradation (PC3-AR-V7 cells) using SARD compounds of this invention (11, 12 and 20). PC-3 prostate cancer cells were serum stably transfected with a lentivirus construct for AR-V7. Once the stable cells were selected, the cells were plated in 6 well plates at 1 million cells/well. The cells were treated as indicated in the figure (µM) and Western blot performed for AR and actin. The results show that the SARDs have the potential to degrade truncated versions of AR such AR-V7, while enzalutamide or ARN-509 have no effect of the AR-V7 expression, suggesting that SARDs of this invention, unlike enzalutamide and ARN-509, can treat AR-V7 dependent CRPC. (Example 7) [0048]

cells, further supporting their use in the treatment of AR-SV-driven CRPC. (Example 7)

[0049] Figure 5 presents SARD degradation of AR in LNCaP cells using 11. (Example 7)

[0050] Figures 6A-6C present SARD degradation of AR-FL and AR-V7 in 22RV-1 cells using (Figure 6A) ASC-J9, (Figure 6B) ARN-509 and (Figure 6C) 11. (Example 7)

[0051] Figures 7A-7D present that 11 inhibits transactivation of AR-NTD-DBD-hinge (A/BCD) AR construct which lacks the LBD. (Figure 7A) AR A/BCD increases GRE-LUC reporter activity. AR A/BCD construct that lacks the ligand binding domain or empty vector was transfected into HEK- 293 cells along with GRE-LUC and CMV-renilla LUC. Forty eight hours after transfection cells were harvested and luciferase assay performed. (Figure 7B) AR A/BCD activity was inhibited by 11. The A/BCD AR construct that lacks the ligand binding domain (LBD) was transfected along with GRE- LUC and CMV-LUC. Cells were treated 24 hrs after transfection as indicated in the figure and luciferase assay performed 48 hrs after transfection.11 (a SARD) inhibited the activity of construct lacking LBD confirming the binding to an alternate site in addition to the LBD. (Figure 7C) and (Figure 7D) Non-SARD antagonists ARN-509 and enzalutamide did not inhibit the activity of this AR construct lacking the LBD, suggesting that of the compounds tested, only SARDs of this invention have the ability to inhibit ligand independent AR activity. (Example 9)

[0052] Figures 8A-8B present data comparing compounds 11, 12, and 14 with galeterone, EPI- 001, and enzalutamide in AR transactivation studies. (Figure 8A) 11, 12, and 14, galeterone, EPI- 001, and enzalutamide; and (Figure 8B) 11, galeterone, and enzaluatamide. SARDs of this invention more potently inhibited (AR-FL) transactivation. (Example 10)

[0053] Figures 9A-9D demonstrate that 11 inhibited tumor growth of an aggressive prostate cancer (22RV-1) that expresses an AR splice variant (growth driven by AR-V7). (Figure 9A) 11 significantly reduced tumor volume and (Figure 9B) tumor weight in a 22RV-1 xenograft tumor study, whereas AR antagonist enzalutamide did not have any effect compared to vehicle. (Figure 9C) shows tumor expressed levels of AR-FL and AR-V7 were decreased by 11 but not enzalutamide, demonstrating that in vivo activity correlated with AR degradation in the tumors; and (Figure 9D) demonstrates an in vivo antiandrogenic tone in gene expression as the serum PSA in these animals was decreased by 11 but not enzalutamide in this 22RV-1 xenograft study. (Example 11) [0054]

(Figure 10A) decreased tumor volume and (Figure 10B) weights, and (Figure 10C) serum PSA levels in animals treated with 11 when compared to vehicle. (Example 11)

[0055] Figure 11 presents degradation in LNCaP cells using 27, 20, 12, 23 and 32. LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free conditions for 3 days. The cells were treated as indicated in the figure, harvested, protein extracted, and Western blotted for AR. SARDs demonstrated selective degradation of AR (i.e., SARD activity) in the nM range, i.e., at concentrations comparable to their antagonist IC50 values. LNCaP cells are known to express the AR mutant T877A, demonstrating the ability to degrade resistance conferring mutant androgen receptors. (Example 7)

[0056] Figure 12 presents 22RV-1 Western blots: 22RV-1 cells were plated in 6 well plates at 1- 1.5 million cells/well in growth medium (RPMI + 10% FBS). Next day, medium was changed and treated with vehicle or a dose response of compounds 20, 24 and 30. After overnight treatment (12- 16 hrs), cells were washed in ice cold PBS and harvested by scrapping in 1 mL PBS. Cells were pelleted, protein extracted, quantified using BCA assay, and equal quantity of protein was fractionated on an SDS-PAGE. The proteins were transferred to nylon membrane and Western blotted with AR antibody (N20 from SCBT) and actin antibody. Compounds 20, 24 and 30 were capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR-SV) in 22RV-1 cells, suggesting that SARDs may be able to overcome wildtype or AR-V7 dependent prostate cancers. (Example 7) [0057] Figure 13 presents degradation in LNCaP cells (top) and 22RV-1 cells (bottom) using 31 vs. galeterone. Using the methods described in the legends for Figure 11 (LNCaP) and Figure 12 (22RV-1), 31 was compared to galeterone (a clinical lead SARD). While 31 demonstrated SARD activity in both LNCaP (mutant AR harboring T877A mutation) and 22RV-1 (growth dependent on AR-SV lacking a LBD) cells, galeterone demonstrated little to no AR degradation in these models. (Example 7)

[0058] Figure 14 presents degradation in LNCaP cells using a dose-response of 12 or ARN-509. Using the methods described in the legend for Figure 11 (LNCaP), SARD activity for 12 was compared to known SARD ARN-509. 12 demonstrated activity in the nM range (100-1000 nM) whereas ARN-509 only had activity at 10,000 nM. (Example 7) [0059]

the legend for Figure 12 (22RV-1), SARD activity for 31 was demonstrated as degradation of full length (AR) and truncated splice variant (AR-V7) androgen receptor. (Example 7)

[0060] Figure 16 presents degradation in LNCaP cells using 70 and 73. Using the methods described in the legend for Figure 11 (LNCaP), SARD activity for 70 and 73 was demonstrated at concentrations as low as 100 nM. This demonstrates that benzimidazoles of this invention also demonstrate potent SARD activity. (Example 7)

[0061] Figures 17A-17C present biophysical data that suggests that SARDs bind to the N- terminal domain of the AR (in addition to the LBD in the C-terminus). (Figure 17A) A dose- dependent shift in the fluorescence intensity, i.e., fluorescent quenching, was observed with 11 when incubated with AR AF-1. (Figure 17B) The fluorescence shoulder observed at 307 nm, which corresponds to tyrosine residues in the AF-1, is shifted by 11. The overall fluorescence is also markedly altered by 11. (Figure 17C) Data shown was plotted as difference in fluorescence between control and 11 treated samples (fluorescence in the absence of compound– fluorescence in the presence of compound), a dose dependent increase was observed in the presence of 11. Cumulatively, these data suggest a direct interaction between 11 and AR AF-1. (Example 12)

[0062] Figure 18 demonstrates degradation in LNCaP cells using a SARD compound of this invention (100). LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free conditions for 3 days. The cells were treated as indicated in the figure, harvested, protein extracted, and Western blotted for AR. (Example 8)

[0063] Figure 19 demonstrates via Western blot as described above for Figure 12, that 100, 102, and 130 degraded AR-FL and AR-SV in 22RV-1 cells.100, 102, and 130 were capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR-SV) in 22RV-1 cells, suggesting that SARDs of this invention may be able to overcome AR-V7 dependent prostate cancers. (Example 8) [0064] Figure 20 presents degradation in 22RV-1 cells as described above for Figure 12, using 130 vs. galeterone. 130 was compared to galeterone (a clinical lead SARD). 130 demonstrated SARD activity in 22RV-1 (growth dependent on AR-SV, an AR variant lacking a LBD) cells which was comparable to galeterone. (Example 8)

[0065] Figure 21 presents degradation in LNCaP cells using 135 and 102. Using the methods described in the legend for Figure 11, SARD activities for 135 and 102 were demonstrated. These compo

such as these may be useful in advanced prostate cancer and/or CRPC. (Example 8)

[0066] Figure 22 presents degradation in LNCaP cells and 22RV-1 cells using 103 and 104. Using the methods described in the legends for Figure 11 (LNCaP) and Figure 12 (22RV-1), 103 and 104 demonstrated SARD activity in both LNCaP (mutant AR harboring T877A mutation) and 22RV- 1 (growth dependent on AR-SV lacking a LBD) cells. (Example 8)

[0067] Figure 23 presents degradation in 22RV-1 cells using 130. Using the methods described in the legend for Figure 12, compound 130 demonstrated SARD activity at least at the 10 µM concentration. (Example 8)

[0068] Figure 24 presents degradation in 22RV-1 cells using 134 and 130. Using the methods described in the legend for Figure 12, compounds 134 and 130 each demonstrated SARD activity at least at the 10 µM concentration. (Example 8)

[0069] Figure 25 presents degradation in LNCaP cells using 101, 105, 106, 107 and 108. Using the methods for Figure 11 above, 101, 105, 106, 107 and 108 each demonstrated the ability to degrade the AR in the nM range. (Example 8)

[0070] Figure 26 depicts degradation in LNCaP cells using 200 and ARN-509. LNCaP cells treated with 200 were lysed and subjected to Western blot analysis, as described above. (Example 13 and 14)

[0071] Figure 27 depicts degradation in 22RV-1 cells using 200 and 201. 22RV-1 cells treated with 200 or 201 were lysed and subjected to Western blot analysis, as described above. (Example 13 and 14)

[0072] Figure 28 depicts degradation in 22RV-1 cells using 201. 22RV-1 cells treated with 201 were lysed and subjected to Western blot analysis, as described above. (Example 13 and 14)

[0073] Figures 29A-29O depict transactivation data, binding, and AR-FL and AR-SV degradation for SARDs compounds of this invention. (Figure 29A) presents transactivation data for 42 (IC 50 = 1015 nM) and binding (K i = 86.1 nM). (Example 5) (Figure 29B) presents transactivation data for 41 (IC50 = >10,000 nM) and binding (Ki = 84.3 nM). (Example 5) (Figure 29C) presents (1) transactivation data for 132 (IC50 = 978.1 nM) and binding (Ki = 353.2 nM), (2) AR full length degradation for 132, and (3) AR splice variant degradation for 132. (Example 6) (Figure 29D) presents transactivation data for 40 (IC50 = 1032.1 nM) and binding (Ki = 134.9 nM). (Example 5) (Figure 29E) presents (1) transactivation data for 92 (IC50 = 946.8 nM) and binding (Ki = nM), (2) AR fu

(Figure 29F) presents (1) transactivation data for 39 (IC50 = 233.8 nM) and binding (Ki = 719.9 nM), (2) AR full length degradation for 39.

[0074] Figures 30A-30D present Hershberger assay: Mice (6-7 weeks old) were treated with vehicle or indicated SARDs (100 mg/kg/day twice daily) for 14 days orally. Animals were sacrificed, and seminal vesicles weights were recorded and represented. Results: (Figure 30A) and (Figure 30D) SARDs demonstrated various degrees of decreased seminal vesicles (S.V.) weight, (Figure 30B) increased in body weight (B.Wt.), and (Figure 30C) decreased prostate weight. This behavior is consistent with an in vivo antiandrogenic effect exerted by SARDs of this invention. (Example 16) [0075] Figure 31 demonstrates that 103 slowed prostate cancer tumor growth in patient-derived xenografts (PDX) despite low levels in the plasma. SARD 103 selectively accumulated in tumor. NSG mice were implanted with patient-derived prostate cancer xenografts (PDX). Animals were treated for 14 days and tumor volumes were measured twice weekly, as shown in the graph. Animals were sacrificed, 103 was extracted from the serum and tumor and measured using LC-MS/MS metho

in plasma (see Example 16, Table 15), possibly providing an explanation for anti-tumor activity despite low levels of SARD in the plasma. (Example 16)

[0076] Figure 32 presents data in a mouse xenograft model treated with 103 and 36. The % change in tumor volume is presented using 103 and 36.

In this case, galeterone potently suppressed at 100 nM but the effect was not dose responsive, reversing at higher doses. (Example 10)

[0080] Figure 36 presents the effect of known AR antagonists compared to SARD 96 on SRB- LNCaP cell growth: LNCaP cells were plated in 96 well plates at 10,000 cells/well in RPMI + 1% csFBS without phenol red.

At the end of 6 days, the cells were fixed and stained with sulphorhodamine blue (SRB) stain. 96 demonstrated a robust and dose-dependent anti- proliferative effect whereas enzalutamide and ARN-509 only partially suppressed growth and galeterone did not exhibit dose-dependent effects.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0098] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0099] Androgens act in cells by binding to the AR, a member of the steroid receptor superfamily of transcription factors. As the growth and maintenance of prostate cancer (PCa) is largely controlled by circulating androgens, treatment of PCa heavily relies on therapies that target AR. Treatment with AR antagonists such as enzalutamide, flutamide, bicalutamide or hydroxyflutamide to disrupt receptor activation has been successfully used in the past to reduce PCa growth. All currently available AR antagonists competitively bind AR and recruit corepressors such as NCoR and SMRT to repr

increased expression of coactivators lead to functional impairment of antagonists or even transformation of antagonists into agonists. Studies have demonstrated that mutation of W741, T877, and F876 within AR converts bicalutamide, hydroxyflutamide, and enzalutamide respectively, to agonists. Similarly, increased intracellular cytokines recruit coactivators instead of corepressors to AR-responsive promoters subsequently converting bicalutamide to an agonist.

[00100] Despite initial response to androgen deprivation therapy (ADT), PCa disease progression is inevitable and the cancer emerges as castration resistant prostate cancer (CRPC). The primary reason for castration resistant prostate cancer (CRPC) re-emergence is re-activation of androgen receptor (AR) by alternate mechanisms such as:

(a) intracrine androgen synthesis;

(b) expression of AR splice variants (AR-SV) that lack ligand binding domain (LBD); (c) AR-LBD mutations with potential to resist antagonists;

(d) hyper-sensitization of AR to low androgen levels or promiscuous AR activation via other hormones (e.g., progestins, mineralocorticoids, estrogens, glucocorticoids, etc.), possibly due to AR gene amplification or AR mutation;

(e) amplication of the AR gene within the tumor; and

(f) over expression of coactivators.

[00101] In one embodiment, this invention is directed to novel selective androgen receptor degrader (SARD) compounds, which inhibit the growth of prostate cancer (PCa) cells and tumors that are dependent on AR full length (AR-FL) including pathogenic and resistance-conferring mutation and/or wildtype, and/or AR splice variants (AR-SV) for proliferation.

[00256] The term“advanced prostate cancer” refers to metastatic cancer having originated in the prostate, and having widely metastasized to beyond the prostate such as the surrounding tissues to include the seminal vesicles the pelvic lymph nodes or bone, or to other parts of the body. Prostate cancer pathologies are graded with a Gleason grading from 1 to 5 in order of increasing malignancy. In another embodiment, patients with significant risk of progressive disease and/or death from prostate cancer should be included in the definition and that any patient with cancer outside the prostate capsule with disease stages as low as IIB clearly has“advanced” disease. In another embodiment,“advanced prostate cancer” can refer to locally advanced prostate cancer.

[00257] Men with advanced prostate cancer often receive treatment to block the production of androgens, which are male sex hormones that may help prostate tumors grow. However, prostate cancers that initially respond to antiandrogen therapy eventually develop the ability to grow without androgens. Such cancers are often referred to as hormone refractory, androgen independent, or castration resistant.

[00258] In one embodiment, the advanced prostate cancer is castration resistant prostate cancer.

[00259] The term "castration resistant prostate cancer" (CRPC) refers to advanced prostate cancer that is worsening or progressing while the patient remains on ADT or other therapies to reduce testosterone, or prostate cancer which is considered hormone refractory, hormone naïve, androgen independent or chemical or surgical castration resistant. In another embodiment, CRPC is a result of AR activation by intracrine androgen synthesis. In another embodiment, CRPC is a result of expression of AR splice variants (AR-SV) that lack ligand binding domain (LBD). In another embodiment, CRPC is a result of expression of AR-LBD mutations with potential to resist antagonists. In another embodiment, castration resistant prostate cancer (CRPC) is an advanced prostate cancer which developed despite ongoing ADT and/or surgical castration. In one embodiment, castration resistant prostate cancer is defined as prostate cancer that continues to progress or worsen or adversely affect the health of the patient despite prior surgical castration, continued treatment with gonadotropin releasing hormone agonists (e.g., leuprolide) or antagonists (e.g., degarelix), antiandrogens (e.g., bicalutamide, flutamide, enzalutamide, ketoconazole, aminoglutethamide), chemotherapeutic agents (e.g., docetaxel, paclitaxel, cabazitaxel, adriamycin, mitoxantrone, estramustine, cyclophosphamide), kinase inhibitors (imatinib (Gleevec®) or gefitinib (Iressa®), caboza

(sipuleucel-T (Provenge®), GVAX, etc.), herbal (PC-SPES) and lyase inhibitor (abiraterone) as evidenced by increasing or higher serum levels of prostate specific antigen (PSA), metastasis, bone metastasis, pain, lymph node involvement, increasing size or serum markers for tumor growth, worsening diagnostic markers of prognosis, or patient condition.

[00260] In one embodiment, castration resistant prostate cancer is defined as hormone naïve prostate cancer.

[00261] Many early prostate cancers require androgens for growth, but advanced prostate cancers are in some embodiments, androgen-independent, or hormone naïve. In one embodiment, in men with castration resistant prostate cancer, the tumor cells may have the ability to grow in the absence of androgens (hormones that promote the development and maintenance of male sex characteristics).

[00262] In one embodiment, the term“androgen deprivation therapy” (ADT) or“traditional androgen deprivation therapy” is directed to orchidectomy (surgical castration) wherein the surgeon removes the testicles. In another embodiment, the term "androgen deprivation therapy" or“traditional androgen deprivation therapy” is directed to administering luteinizing hormone-releasing hormone (LHRH) analogs: these drugs lower the amount of testosterone made by the testicles. Examples of LHRH analogs available in the United States include leuprolide (Lupron®, Viadur®, Eligard®), goserelin (Zoladex®), triptorelin (Trelstar®), and histrelin (Vantas®). In another embodiment, the term“androgen deprivation therapy” or“traditional androgen deprivation therapy” is directed to administering antiandrogens: anti-androgens block the body's ability to use any androgens. Even after orchidectomy or during treatment with LHRH analogs, a small amount of androgens is still made by the adrenal glands. Examples of antiandrogens drugs include enzalutamide (Xtandi®), apalutamide (Erleada®), flutamide (Eulexin®), bicalutamide (Casodex®), and nilutamide (Nilandron®). In another embodiment, the term“androgen deprivation therapy” or“traditional androgen deprivation therapy” is directed to administering luteinizing hormone-releasing hormone (LHRH) antagonists such as abarelix (Plenaxis ®) or degarelix (Firmagon®) (approved for use by the FDA in 2008 to treat advanced prostate cancer). In another embodiment, the term“androgen deprivation therapy” or “traditional androgen deprivation therapy” is directed to administering 5a-reductase inhibitors such as finasteride (Proscar®) and dutasteride (Avodart®): 5a-reductase inhibitors block the body’s ability to convert testosterone to the more active androgen, 5a-dihydrotestosterone (DHT).

reducing, in another embodiment, the incidence, severity or pathogenesis of a disease, disorder or condition. In embodiment, the term treatment refers to delayed progression of, prolonged remission of, reduced incidence of, or amelioration of symptoms associated with the disease, disorder or condition. In one embodiment, the terms“treating”“reducing”,“suppressing” or“inhibiting” refer to a reduction in morbidity, mortality, or a combination thereof, in association with the indicated disease, disorder or condition. In one embodiment, the term“progression” refers to an increasing in scope or severity, advancing, growing or becoming worse. The term“recurrence” means, in another embodiment, the return of a disease after a remission.

[00281] Muscle atrophy (MA) is characterized by wasting away or diminution of muscle and a decrease in muscle mass. For example, post-polio MA is a muscle wasting that occurs as part of the post-polio syndrome (PPS). The atrophy includes weakness, muscle fatigue, and pain.

[00282] Another type of MA is X-linked spinal-bulbar muscular atrophy (SBMA--also known as Kennedy's Disease). This disease arises from a defect in the androgen receptor gene on the X chromosome, affects only males, and its onset is in late adolescence to adulthood. Proximal limb and bulbar muscle weakness results in physical limitations including dependence on a wheelchair in some cases. The mutation results in an extended polyglutamine tract at the N-terminal domain of the androgen receptor (polyQ AR). Binding and activation of the polyQ AR by endogeneous androgens (testosterone and DHT) results in unfolding and nuclear translocation of the mutant androgen receptor. These steps are required for pathogenesis and results in partial loss of transactivation function (i.e., an androgen insensitivity) and a poorly understood neuromuscular degeneration. Currently there are no disease-modifying treatments but rather only symptom directed treatments. Efforts to target the polyQ AR as the proximal mediator of toxicity by harnessing cellular machinery to promote its degradation hold promise for therapeutic invention. Selective androgen receptor degraders such as those reported herein bind to and degrade a variety of androgen receptors (full length, splice variant, antiandrogen resistance mutants, etc.), indicating that they are promising leads for treatment of SBMA. This view is supported by the observation that peripheral polyQ AR anti- sense therapy rescues disease in mouse models of SBMA (Cell Reports 7, 774–784, May 8, 2014). [00283

[00284] As used herein,“androgen receptor associated conditions” or“androgen sensitive diseases or disorders” are conditions, diseases, or disorders that are modulated by or whose pathogenesis is dependent upon the activity of the androgen receptor. The androgen receptor is expressed in most tissues of the body however it is overexpressed in, inter alia, the prostate and skin. ADT has been the mainstay of prostate cancer treatment for many years, and a SARD may also be useful also in treating various prostate cancers, benign prostatic hypertrophy, prostamegaly, and other maladies of the prostate.

In one embodiment, the precursor of prostate cancers is prostatic intraepithelial neoplasia (PIN). In another embodiment, the precursor of prostate cancer is atypical small acinar proliferation (ASAP).

[00317] Although traditional antiandrogens such as enzalutamide, apalutamide (ARN-509), bicalutamide and flutamide and androgen deprivation therapies (ADT) such as leuprolide were approved for use in prostate cancer, there is significant evidence that antiandrogens could also be used in a variety of other hormone dependent and hormone independent cancers. For example, antiandrogens have been successfully tested in breast cancer (enzalutamide; Breast Cancer Res. (2014) 16(1): R7), non-small cell lung cancer (shRNAi AR), renal cell carcinoma (ASC- J9), partial androgen insensitivity syndrome (PAIS) associated malignancies such as gonadal tumors and seminoma, advanced pancreatic cancer (World J. Gastroenterology 20(29):9229), cancer of the ovary,

731; ADT was tested in AR-expressing recurrent/metastatic salivary gland cancers and was confirmed to have benefit on progression free survival and overall survival endpoints), bladder cancer (Oncotarget 6 (30): 29860-29876); Int J. Endocrinol (2015), Article ID 384860), pancreatic cancer, lymphoma (including mantle cell), and hepatocellular carcinoma. Use of a more potent antiandrogen such as a SARD in these cancers may treat the progression of these and other cancers. Many hormonal and non-hormonal cancers may benefit from SARD treatment such as testicular cancer, uterine cancer, ovarian cancer, urogenital cancer, brain cancer, skin cancer, lymphoma, liver cancer, renal cancer, osteosarcoma, pancreatic cancer, endometrial cancer, lung cancer, non-small cell lung cancer (NSCLC), gastric cancer, colon cancer, perianal adenoma, or central nervous system cancer.

[00336] AR plays a role in cancer initiation in hepatocellular carcinoma (HCC). Therefore, targeting AR may be appropriate treatment for patients with early stage HCC. In late-stage HCC disease, there is evidence that metastasis is suppressed by androgens. In another embodiment, the SARDs of this invention are used for treating hepatocellular carcinoma (HCC).

[00337] Locati et al. Head & Neck, 2016, 724-731 demonstrated the use of androgen deprivation therapy (ADT) in AR-expressing recurrent/metastatic salivary gland cancers was confirmed to improve progression free survival and overall survival endpoints. In another embodiment, the SARDs of this invention are used for treating salivary gland cancer.

[00338] Kawahara et al. Oncotarget, 2015, Vol 6 (30), 29860-29876 demonstrated that ELK1 inhibition, together with AR inactivation, has the potential of being a therapeutic approach for bladder cancer. McBeth et al. Int. J Endocrinology, 2015, Vol 20151-10 suggested that the combination of anti-androgen therapy plus glucocorticoids since bladder cancer is believed to have an inflammatory etiology. In another embodiment, the SARDs of this invention are used for treating bladder cancer. Abdominal Aortic Aneurysm (AAA) [00339

major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky. AR blockade (pharmacologic or genetic) reduces AAA. Davis et al. (J Vasc Surg Vol.63, Issue 6, p1602–1612.e2) showed that flutamide (50 mg/kg) or ketoconazole (150 mg/kg) attenuated porcine pancreatic elastase (0.35 U/mL) induced AAA by 84.2% and 91.5% compared to vehicle (121%). Further AR -/- mice showed attenuated AAA growth (64.4%) compared to wildtype (both treated with elastase). Correspondingly, administration of a SARD to a patient suffering from an AAA may help reverse, treat or delay progression of AAA to the point where surgery is needed.

[00343] In one embodiment, this invention provides a method of treating a subject suffering from a burn, or reducing the incidence of, or mitigating the severity of, or enhancing or hastening healing of a burn in a subject, the method comprises administering to said subject a therapeutically effective amount of a compound of this invention or its isomer, pharmaceutically acceptable salt, pharmaceutical product, polymorph, hydrate or any combination thereof. In another embodiment, the compound is any one of compounds 11-27, 30-47, 11R, 70-79, 80, 90-99, 100-115, 130-137, 200- 205, and 300-308 as described herein. Wounds and/or ulcers are normally found protruding from the skin or on a mucosal surface or as a result of an infarction in an organ. A wound may be a result of a soft tissue defect or a lesion or of an underlying condition. In one embodiment, the term“wound” denotes a bodily injury with disruption of the normal integrity of tissue structures. The term is also intended to encompass the terms“sore”,“lesion”,“necrosis” and“ulcer”. In one embodiment, the term“sore” refers to any lesion of the skin or mucous membranes and the term“ulcer” refers to a local defect, or excavation, of the surface of an organ or tissue, which is produced by the sloughing of necrotic tissue. Lesion generally relates to any tissue defect. Necrosis is related to dead tissue resulting from infection, injury, inflammation or infarctions. All of these are encompassed by the term “wound”, which denotes any wound at any particular stage in the healing process including the stage before any healing has initiated or even before a specific wound like a surgical incision is made (prophylactic treatment).

[00344] Examples of wounds which can be prevented and/or treated in accordance with the present invention are, e.g., aseptic wounds, contused wounds, incised wounds, lacerated wounds, non- penetrating wounds (i.e. wounds in which there is no disruption of the skin but there is injury to underlying structures), open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds, subcutaneous wounds, etc. Examples of sores are bed sores, canker sores, chrome sores, cold sores, pressure sores etc. Examples of ulcers are, e.g., peptic ulcer, duodenal ulcer, gastric ulcer, gouty ulcer, diabetic ulcer, hypertensive ischemic ulcer, stasis ulcer, ulcus cruris (venous ulcer), sublingual ulcer, submucous ulcer, symptomatic ulcer, trophic ulcer, tropical ulcer, veneral ulcer, e.g. caused by gonorrhoea (including urethritis, endocervicitis and proctitis). Conditions related to wounds or sores which may be successfully treated according to the invention are burns, anthrax, tetanus, gas gangrene, scalatina, erysipelas, sycosis barbae, folliculitis, impetigo contagiosa, or impetigo bullosa, etc. Th

and“sore” and, furthermore, the terms are often used at random. Therefore as mentioned above, in the present context the term“wounds” encompasses the term“ulcer”,“lesion”,“sore” and “infarction”, and the terms are indiscriminately used unless otherwise indicated.

[00345] The kinds of wounds to be treated according to the invention include also: i) general wounds such as, e.g., surgical, traumatic, infectious, ischemic, thermal, chemical and bullous wounds; ii) wounds specific for the oral cavity such as, e.g., post-extraction wounds, endodontic wounds especially in connection with treatment of cysts and abscesses, ulcers and lesions of bacterial, viral or autoimmunological origin, mechanical, chemical, thermal, infectious and lichenoid wounds; herpes ulcers, stomatitis aphthosa, acute necrotising ulcerative gingivitis and burning mouth syndrome are specific examples; and iii) wounds on the skin such as, e.g., neoplasm, burns (e.g. chemical, thermal), lesions (bacterial, viral, autoimmunological), bites and surgical incisions. Another way of classifying wounds is as: i) small tissue loss due to surgical incisions, minor abrasions and minor bites, or as ii) significant tissue loss. The latter group includes ischemic ulcers, pressure sores, fistulae, lacerations, severe bites, thermal burns and donor site wounds (in soft and hard tissues) and infarctions.

[00346] In other aspects of the invention, the wound to be prevented and/or treated is selected from the group consisting of aseptic wounds, infarctions, contused wounds, incised wounds, lacerated wounds, non-penetrating wounds, open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds and subcutaneous wounds.

[00347] Other wounds which are of importance in connection with the present invention are wounds like ischemic ulcers, pressure sores, fistulae, severe bites, thermal burns and donor site wounds.

[00348] Ischemic ulcers and pressure sores are wounds, which normally only heal very slowly and especially in such cases an improved and more rapid healing is of course of great importance for the patient. Furthermore, the costs involved in the treatment of patients suffering from such wounds are markedly reduced when the healing is improved and takes place more rapidly.

[00349] Donor site wounds are wounds which e.g. occur in connection with removal of hard tissue from one part of the body to another part of the body e.g. in connection with transplantation. The wounds resulting from such operations are very painful and an improved healing is therefore most valuable.

[00350] The term“skin” is used in a very broad sense embracing the epidermal layer of the skin and in those cases where the skin surface is more or less injured also the dermal layer of the skin. Apart from t

connective tissue layer of the skin is called the dermis.

[00351] Since the skin is the most exposed part of the body, it is particularly susceptible to various kinds of injuries such as, e.g., ruptures, cuts, abrasions, burns and frostbites or injuries arising from various diseases. Furthermore, much skin is often destroyed in accidents. However, due to the important barrier and physiologic function of the skin, the integrity of the skin is important to the well-being of the individual, and any breach or rupture represents a threat that must be met by the body in order to protect its continued existence.

[00352] Apart from injuries on the skin, injuries may also be present in all kinds of tissues (i.e. soft and hard tissues). Injuries on soft tissues including mucosal membranes and/or skin are especially relevant in connection with the present invention.

[00353] Healing of a wound on the skin or on a mucosal membrane undergoes a series of stages that results either in repair or regeneration of the skin or mucosal membrane. In recent years, regeneration and repair have been distinguished as the two types of healing that may occur. Regeneration may be defined as a biological process whereby the architecture and function of lost tissue are completely renewed. Repair, on the other hand, is a biological process whereby continuity of disrupted tissue is restored by new tissues which do not replicate the structure and function of the lost ones.

[00354] The majority of wounds heal through repair, meaning that the new tissue formed is structurally and chemically unlike the original tissue (scar tissue). In the early stage of the tissue repair, one process which is almost always involved is the formation of a transient connective tissue in the area of tissue injury. This process starts by formation of a new extracellular collagen matrix by fibroblasts. This new extracellular collagen matrix is then the support for a connective tissue during the final healing process. The final healing is, in most tissues, a scar formation containing connective tissue. In tissues which have regenerative properties, such as, e.g., skin and bone, the final healing includes regeneration of the original tissue. This regenerated tissue has frequently also some scar characteristics, e.g. a thickening of a healed bone fracture.

[00355] Under normal circumstances, the body provides mechanisms for healing injured skin or mucosa in order to restore the integrity of the skin barrier or the mucosa. The repair process for even minor ruptures or wounds may take a period of time extending from hours and days to weeks. However, in ulceration, the healing can be very slow and the wound may persist for an extended period of time, i.e. months or even years. [00356

delayed wound healing. In one embodiment, the methods of this invention, provide for treating a subject suffering from a wound or a burn via the administration of a SARD according to this invention. In one embodiment, the SARD promotes resolving of the burn or wound, or in another embodiment, participates in the healing process of a burn or a wound, or in another embodiment, treats a secondary complication of a burn or wound.

[00357] In one embodiment, the treatment of burns or wounds further incorporates the use of additional growth factors like epidermal growth factor (EGF), transforming growth factor-a (TGF- a), platelet derived growth factor (PDGF), fibroblast growth factors (FGFs) including acidic fibroblast growth factor (a-FGF) and basic fibroblast growth factor (b-FGF), transforming growth factor-b (TGF-b) and insulin like growth factors (IGF-1 and IGF-2), or any combination thereof, which are promoters of wound healing.

[00358] Wound healing may be measured by many procedures known in the art, including wound tensile strength, hydroxyproline or collagen content, procollagen expression, and re-epithelialization. As an example, a SARD as described herein is administered orally or topically, at a dosage of about 0.1-1 mg per day. Therapeutic effectiveness is measured as effectiveness in enhancing wound healing. Enhanced wound healing may be measured by known techniques such as decrease in healing time, increase in collagen density, increase in hydroxyproline, reduction in complications, increase in tensile strength, and increased cellularity of scar tissue.

[00359] In one embodiment, the term“treating” and its included aspects, refers to the administration to a subject with the indicated disease, disorder or condition, or in some embodiments, to a subject predisposed to the indicated disease, disorder or condition. The term“predisposed to” is to be considered to refer to, inter alia, a genetic profile or familial relationship which is associated with a trend or statistical increase in incidence, severity, etc. of the indicated disease. In some embodiments, the term“predisposed to” is to be considered to refer to inter alia, a lifestyle which is associated with increased risk of the indicated disease. In some embodiments, the term“predisposed to” is to be considered to refer to inter alia, the presence of biomarkers which are associated with the indicated disease, for example, in cancer, the term“predisposed to” the cancer may comprise the presence of precancerous precursors for the indicated cancer.

[00360] In some embodiments, the term“reducing the pathogenesis” is to be understood to encompass reducing tissue damage, or organ damage associated with a particular disease, disorder or condit

encompass reducing the incidence or severity of an associated disease, disorder or condition, with that in question. In another embodiment, the term“reducing the pathogenesis” is to be understood to encompass reducing the number of associated diseases, disorders or conditions with the indicated, or symptoms associated thereto.

In one embodiment, the present invention encompasses administering the compounds of the present invention to a male subject. In one embodiment, the present invention encompasses administering the compounds of the present invention to a female subject.

[00363] This invention provides, in other embodiments, pharmaceutical products of the compounds described herein. The term“pharmaceutical product” refers, in other embodiments, to a composition suitable for pharmaceutical use (pharmaceutical composition), for example, as described herein.

[00364] The compounds of the invention can be administered alone or as an active ingredient of a formulation. Thus, the present invention also includes pharmaceutical compositions of compounds of the invention or its isomer, pharmaceutically acceptable salt, pharmaceutical product, polymorph, hydrate or any combination thereof containing, for example, one or more pharmaceutically acceptable carriers.

[00365] Numerous standard references are available that describe procedures for preparing various formulations suitable for administering the compounds according to the invention. Examples of potential formulations and preparations are contained, for example, in the Handbook of Pharmaceutical Excipients, American Pharmaceutical Association (current edition); Pharmaceutical Dosag

Marcel Dekker, Inc., as well as Remington's Pharmaceutical Sciences (Arthur Osol, editor), 1553- 1593 (current edition).

[00366] The mode of administration and dosage form are closely related to the therapeutic amounts of the compounds or compositions which are desirable and efficacious for the given treatment application.

[00367] The pharmaceutical compositions containing a compound of this invention can be administered to a subject by any method known to a person skilled in the art, such as orally, parenterally, intravascularly, paracancerally, transmucosally, transdermally, intramuscularly, intranasally, intravenously, intradermally, subcutaneously, sublingually, intraperitoneally, intraventricularly, intracranially, intravaginally, by inhalation, rectally, intratumorally, or by any means in which the composition can be delivered to tissue (e.g., needle or catheter). Alternatively, topical administration may be desired for application to the dermal, ocular or mucosal surfaces. Another method of administration is via aspiration or aerosol formulation. Further, in another embodiment, the pharmaceutical compositions may be administered topically to body surfaces, and are thus formulated in a form suitable for topical administration. Suitable topical formulations include gels, ointments, creams, lotions, drops and the like. For topical administration, the compounds of this invention or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are prepared and applied as solutions, suspensions, or emulsions in a physiologically acceptable diluent with or without a pharmaceutical carrier.

[00368] Suitable dosage forms include but are not limited to oral, rectal, sub-lingual, mucosal, nasal, ophthalmic, subcutaneous, intramuscular, intravenous, transdermal, spinal, intrathecal, intra- articular, intra-arterial, sub-arachinoid, bronchial, lymphatic, and intra-uterile administration, and other dosage forms for systemic delivery of active ingredients. In some applications, formulations suitable for oral administration are preferred. In some applications, formulations suitable for topical administration are preferred.

[00369] Topical Administration: In a typical embodiment, the compounds of the invention are administered topically. Topical administration is especially appropriate for hirsutism, alopecia, acne and excess sebum. The dose will vary, but as a general guideline, the compound will be present in a dermatologically acceptable carrier in an amount of from about 0.01 to 50 w/w %, and more typically from about 0.1 to 10 w/w %. Typically, the dermatological preparation will be applied to the aff

be applied to the skin or hair, and which will allow the drug to diffuse to the site of action. More specifically, it refers to a site where inhibition of androgen receptor or degradation of androgen receptor is desired.

[00370] In a further embodiment, the compounds of the invention are used topically to relieve alopecia, especially androgenic alopecia. Androgens have a profound effect on both hair growth and hair loss. In most body sites, such as the beard and pubic skin, androgens stimulate hair growth by prolonging the growth phase of the hair cycle (anagen) and increasing follicle size. Hair growth on the scalp does not require androgens but, paradoxically, androgens are necessary for the balding on the scalp in genetically predisposed individuals (androgenic alopecia) where there is a progressive decline in the duration of anagen and in hair follicle size. Androgenic alopecia is also common in women where it usually presents as a diffuse hair loss rather than showing the patterning seen in men.

[00371] While the compounds of the invention will most typically be used to alleviate androgenic alopecia, the invention is not limited to this specific condition. The compounds of the invention may be used to alleviate any type of alopecia. Examples of non-androgenic alopecia include alopecia areata, alopecia due to radiotherapy or chemotherapy, scarring alopecia, stress related alopecia, etc. As used in this application“alopecia” refers to partial or complete hair loss on the scalp.

[00372] Thus, the compounds of the invention can be applied topically to the scalp and hair to prevent or alleviate balding. Further, the compound of the invention can be applied topically in order to induce or promote the growth or regrowth of hair on the scalp.

[00373] In a further embodiment of the invention, a compound of the invention is applied topically in order to prevent the growth of hair in areas where such hair growth in not desired. One such use will be to alleviate hirsutism. Hirsutism is excessive hair growth in areas that typically do not have hair (i.e., a female face). Such inappropriate hair growth occurs most commonly in women and is frequently seen at menopause. The topical administration of the compounds of the invention will alleviate this condition leading to a reduction, or elimination of this inappropriate, or undesired, hair growth.

[00374] The compounds of the invention may also be used topically to decrease sebum production. Sebum is composed of triglycerides, wax esters, fatty acids, sterol esters and squalene. Sebum is produced in the acinar cells of the sebaceous glands and accumulates as these cells age. At matura

the surface of the skin.

[00375] In some individuals, an excessive quantity of sebum is secreted onto the skin. This can have a number of adverse consequences. It can exacerbate acne, since sebum is the primary food source for Propionbacterium acnes, the causative agent of acne. It can cause the skin to have a greasy appearance, typically considered cosmetically unappealing.

[00376] Formation of sebum is regulated by growth factors and a variety of hormones including androgens. The cellular and molecular mechanism by which androgens exert their influence on the sebaceous gland has not been fully elucidated. However, clinical experience documents the impact androgens have on sebum production. Sebum production is significantly increased during puberty, when androgen levels are their highest. Thus the compounds of the invention inhibit the secretion of sebum and thus reduce the amount of sebum on the surface of the skin. The compounds of the invention can be used to treat a variety of dermal diseases such as acne or seborrheic dermatitis.

[00377] In addition to treating diseases associated with excess sebum production, the compounds of the invention can also be used to achieve a cosmetic effect. Some consumers believe that they are afflicted with overactive sebaceous glands. They feel that their skin is oily and thus unattractive. These indiviuals can utilize the compounds of the invention to decrease the amount of sebum on their skin. Decreasing the secretion of sebum will alleviate oily skin in indviduals afflicted with such conditions.

[00378] The compounds of the invention of this invention will typically be administered topically. As used herein, topical refers to application of the compounds of the invention (and optional carrier) directly to the skin and/or hair. The topical composition according to the present invention can be in the form of solutions, lotions, salves, creams, ointments, liposomes, sprays, gels, foams, roller sticks, and any other formulation routinely used in dermatology.

[00379] Thus, a further embodiment relates to cosmetic or pharmaceutical compositions, in particular dermatological compositions, which comprise at least one of the compounds of the invention. Such dermatological compositions will contain from 0.001% to 10% w/w% of the compounds in admixture with a dermatologically acceptable carrier, and more typically, from 0.1 to 5 w/w % of the compounds. Such compositions will typically be applied from 1 to 4 times daily. The reader’s attention is directed to Remington’s Pharmaceutical Science, Edition 17, Mark Publishing Co., Easton, PA for a discussion of how to prepare such formulations. [00380

constituting cleansing soaps or bars. These compositions are prepared according to the usual methods.

[00381] The compounds of the invention can also be used for the hair in the form of aqueous, alcoholic or aqueous-alcoholic solutions, or in the form of creams, gels, emulsions or mousses, or alternatively in the form of aerosol compositions also comprising a propellant under pressure. The composition according to the invention can also be a hair care composition, and in particular a shampoo, a hair-setting lotion, a treating lotion, a styling cream or gel, a dye composition, a lotion or gel for preventing hair loss, etc. The amounts of the various constituents in the dermatological compositions according to the invention are those conventionally used in the fields considered.

[00382] The medicinal and cosmetics containing the compounds of the invention will typically be packaged for retail distribution (i.e., an article of manufacture). Such articles will be labeled and packaged in a manner to instruct the patient how to use the product. Such instructions will include the condition to be treated, duration of treatment, dosing schedule, etc.

[00383] Antiandrogens, such as finasteride or flutamide, have been shown to decrease androgen activity or block androgen action in the skin to some extent but suffer from undesirable systemic effects. An alternative approach is to topically apply a selective androgen receptor degrader (SARD) compound to the affected areas. In one embodiment, such a SARD compound would exhibit potent but local inhibition of AR activity. In another embodiment, the SARD compound would exhibit potent but local degradation of AR activity. In another embodiment, the SARD compound would not penetrate to the systemic circulation of the subject. In another embodiment, the SARD compound would be rapidly metabolized upon entry into the blood, limiting systemic exposure.

[00384] To prepare such pharmaceutical dosage forms, the active ingredient may be mixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration.

[00385] As used herein "pharmaceutically acceptable carriers or diluents" are well known to those skilled in the art. The carrier or diluent may be a solid carrier or diluent for solid formuations, a liquid carrier or diluent for liquid formulations, or mixtures thereof.

[00386] Solid carriers/diluents include, but are not limited to, a gum, a starch (e.g. corn starch, pregeletanized starch), a sugar (e.g., lactose, mannitol, sucrose, dextrose), a cellulosic material (e.g. microc

oxide, talc, or mixtures thereof.

[00387] Oral or Parenteral Administration: In preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed. Thus, for liquid oral preparations, such as, for example, suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like. For solid oral preparations such as, for example, powders, capsules and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Due to their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form. If desired, tablets may be sugar coated or enteric coated by standard techniques.

[00388] For parenteral formulations, the carrier will usually comprise sterile water, though other ingredients, for example, ingredients that aid solubility or for preservation, may be included. Injectable solutions may also be prepared in which case appropriate stabilizing agents may be employed.

[00389] In some applications, it may be advantageous to utilize the active agent in a "vectorized" form, such as by encapsulation of the active agent in a liposome or other encapsulant medium, or by fixation of the active agent, e.g., by covalent bonding, chelation, or associative coordination, on a suitable biomolecule, such as those selected from proteins, lipoproteins, glycoproteins, and polysaccharides.

[00390] Treatment methods of the present invention using formulations suitable for oral administration may be presented as discrete units such as capsules, cachets, tablets, or lozenges, each containing a predetermined amount of the active ingredient as, for example, a powder or granules. Optionally, a suspension in an aqueous liquor or a non-aqueous liquid may be employed, such as a syrup, an elixir, an emulsion, or a draught.

[00391] A tablet may be made by compression or molding, or wet granulation, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine, with the active compound being in a free-flowing form such as a powder or granules which optionally is mixed with, for example, a binder, disintegrant, lubricant, inert diluent, surface active agent, or discharging agent. Molded tablets comprised of a mixture of the powdered active compound with a suitable carrier may be made by molding in a suitable machine. [00392

solution of a sugar, for example sucrose, to which may also be added any accessory ingredient(s). Such accessory ingredient(s) may include flavorings, suitable preservative, agents to retard crystallization of the sugar, and agents to increase the solubility of any other ingredient, such as a polyhydroxy alcohol, for example glycerol or sorbitol.

[00393] Formulations suitable for parenteral administration may comprise a sterile aqueous preparation of the active compound, which preferably is isotonic with the blood of the recipient (e.g., physiological saline solution). Such formulations may include suspending agents and thickening agents and liposomes or other microparticulate systems which are designed to target the compound to blood components or one or more organs. The formulations may be presented in unit-dose or multi- dose form.

[00394] Parenteral administration may comprise any suitable form of systemic delivery. Administration may for example be intravenous, intra-arterial, intrathecal, intramuscular, subcutaneous, intramuscular, intra-abdominal (e.g., intraperitoneal), etc., and may be effected by infusion pumps (external or implantable) or any other suitable means appropriate to the desired administration modality.

[00395] Nasal and other mucosal spray formulations (e.g. inhalable forms) can comprise purified aqueous solutions of the active compounds with preservative agents and isotonic agents. Such formulations are preferably adjusted to a pH and isotonic state compatible with the nasal or other mucous membranes. Alternatively, they can be in the form of finely divided solid powders suspended in a gas carrier. Such formulations may be delivered by any suitable means or method, e.g., by nebulizer, atomizer, metered dose inhaler, or the like.

[00396] Formulations for rectal administration may be presented as a suppository with a suitable carrier such as cocoa butter, hydrogenated fats, or hydrogenated fatty carboxylic acids.

[00397] Transdermal formulations may be prepared by incorporating the active agent in a thixotropic or gelatinous carrier such as a cellulosic medium, e.g., methyl cellulose or hydroxyethyl cellulose, with the resulting formulation then being packed in a transdermal device adapted to be secured in dermal contact with the skin of a wearer.

[00398] In addition to the aforementioned ingredients, formulations of this invention may further include one or more accessory ingredient(s) selected from, for example, diluents, buffers, flavor

(including antioxidants), and the like.

[00399] The formulations of the present invention can have immediate release, sustained release, delayed-onset release or any other release profile known to one skilled in the art.

[00400] It is to be understood that this invention encompasses any embodiment of a compound as described herein, which in some embodiments is referred to as“a compound of this invention”.

The solvent was removed under reduced pressure to give a solid which was treated with 300 mL of H 2 O, extracted with EtOAc (2 × 400 mL). The combined organic extracts were washed with saturated NaHCO3 solution (2 × 300 mL) and brine (300 mL). The organic layer was dried over MgSO4 and concentrated under reduced pressure to give a solid which was purified from column chromatography using CH 2 Cl 2 /EtOAc (80:20) to give a solid. This solid was recrystallized from CH 2 Cl 2 /hexane to give 55.8 g (73.9%) of (2R)-3-bromo-N-[4-cyano-3- (trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide (8) as a light-yellow solid.

General Synthetic Procedure of Compounds 11-27, 11R, 30-32, and 80.

[00415] Step 1. Preparation of (S)-N-(4-cyano-3-(trifluoromethyl)phenyl)-2-methyloxirane-2- carboxamide (10) in THF: A mixture of hydroxylbromide 8 (1.0 g, 2.84 mmol) and potassium carbon

conversion of starting bromide 8 to desired epoxide 10 as monitored by TLC, the solvent was evaporated under reduced pressure to give yellowish residue, which was poured into 20 mL of anhydrous EtOAc. The solution was filtered through Celite® pad to remove K 2 CO 3 residue and condensed under reduced pressure to give a yellowish solid of epoxide 10, which was dissolved in 5 mL of anhydrous THF to prepare a solution of epoxide 10 in THF. The resulting solution was directly used as next reactant without analysis.

[00416] Step 2. NaH of 60% dispersion in mineral oil (228 mg, 5.7 mmol) was added in 30 mL of anhydrous THF solvent into a 100 mL dried two necked round bottom flask equipped with a dropping funnel and substituted indole/pyrrolo-pyridine (2.84 mmol) was added to the solution under argon atmosphere in ice-water bath, and the resulting solution was stirred for 30 min in an ice-water bath. Into the flask, the prepared solution of epoxide 10 (2.84 mmol in THF) was added through dropping funnel under argon atmosphere at the ice-water bath and stirred overnight at RT. After adding 1 mL of H2O (1N HCl in case for compound 15), the reaction mixture was condensed under reduced pressure, and then dispersed into 50 mL of EtOAc, washed with 50 mL (× 2) water, brine, dried over anhydrous MgSO 4 , and evaporated to dryness. The mixture was purified with flash column chromatography as an eluent EtOAc/hexane, and then the condensed compounds were then recrystallized in EtOAc/hexane to give any one of the target products 11-27, 11R, 30-32, and 80.

[00495] Preparation of LDA solution in THF: To a stirred solution of freshly distilled diisopropylamine (0.14 mL, 1.2 mmol) in anhydrous 5 mL of THF was added a solution of n- butyllithium (0.53 mL, 1.32 mmol, 2.5 M solution in hexane) at -78ºC under argon atmosphere. The prepared solution of LDA or commercial 2.0 M LDA was slowly warmed to 0ºC and stirred for 10 min and cooled again to -78ºC. To the LDA solution was added dropwise a solution of 9 (1.0 mmol) in 5 mL of THF for 20 min. 8R in THF was added dropwise through dropping funnel under argon atmosphere at -78ºC. The reaction mixture was stirred at the same temperature for 30 min and quenched by addition of sat. NH 4 Cl. The solution was concentrated under reduced pressure and dispersed into excess EtOAc and dried over Na 2 SO 4 . The solution was concentrated and the resulting solid was recrystallized from EtOAc/hexane or DCM/hexane to give designed compound 10. The mother liquor was concentrated and purified by flash column chromatography (EtOAc/hexane) to give the 10 additionally. Method B. Preparation of Indoles and Carbazoles

[00496] NaH of 60% dispersion in mineral oil (228 mg, 5.7 mmol) was added in 20 mL of anhydrous THF solvent into a 100 mL dried two necked round bottom flask equipped with a dropping funnel. Indole (general structure 12, 2.84 mmol) was added to the solution under argon atmosphere in ice-water bath, and the resulting solution was stirred for 30 min at the ice-water bath. Into the flask, epoxide 11 (2.84 mmol in THF) was added through dropping funnel under argon atmosphere at the ice-water bath and stirred overnight at RT. After adding 1 mL of H2O , the reaction mixture was condensed under reduced pressure, and then dispersed into 50 mL of EtOAc, washed with 50 mL (× 2) water, brine, dried over anhydrous MgSO4, and evaporated to dryness. The mixture was purified with flash column chromatography with an eluent of EtOAc/ hexane, and then the condensed compounds were then recrystallized in EtOAc/hexane to give a target product of general structure 13.

EXAMPLE 5

Androgen Receptor Binding, Transactivation, and Metabolism of Indole, Benzimidazole, and

Indazole SARDs [00614] Objective: To determine SARD binding affinity to the AR-LBD.

[00615] Method: hAR-LBD (633-919) was cloned into pGex4t.1. Large scale GST-tagged AR- LBD was prepared and purified using a GST column. Recombinant AR-LBD was combined with [ 3 H]mibolerone (PerkinElmer, Waltham, MA) in buffer A (10 mM Tris, pH 7.4, 1.5 mM disodium EDTA, 0.25 M sucrose, 10 mM sodium molybdate, 1 mM PMSF) to determine the equilibrium dissociation constant (K d ) of [ 3 H]mibolerone. Protein was incubated with increasing concentrations of [ 3 H]mibolerone with and without a high concentration of unlabeled mibolerone at 4ºC for 18 h in order to determine total and non-specific binding. Non-specific binding was then subtracted from total binding to determine specific binding and non-linear regression for ligand binding curve with one site saturation to determine the Kd of mibolerone.

[00616] Increasing concentrations of SARDs or DHT (range: 10 -12 to 10 -2 M) were incubated with [ 3 H]mibolerone and AR LBD using the conditions described above. Following incubation, the ligand bound AR-LBD complex was isolated using BioGel® HT hydroxyapatite, washed and counted in a scintillation counter after adding scintillation cocktail. Values are expressed as Ki. Transactivation Assay for wt and Mutant AR

[00617] Objective: To determine the effect of SARDs on androgen-induced transactivation of AR wildtype (wt) or AR carrying known AR-LBD mutants (i.e., W741L or T877A).

[00618] Method: HEK-293 cells were plated at 125,000 cells/well of a 24 well plate in DME + 5% csFBS without phenol red. Cells were transfected with 0.25 ug GRE-LUC, 10 ng CMV-renilla LUC, and 50 ng CMV-hAR(wt) or CMV-hAR(W741L) or CMV-hAR(T877A) using lipofectamine transfection reagent in optiMEM medium. Medium was changed 24 h after transfection to DME + 5% csFBS without phenol red and treated with a dose response of various drugs (Table 1: 11-18, 20-27, 30, 31, 33, 70-74) (1 pM to 10 µM). SARDs and antagonists were treated in combination with known agonist 0.1 nM R1881 in order to produce an antagonism curve. Luciferase assay was performed 24 h after treatment on a Biotek synergy 4 plate reader. Firefly luciferase values were normalized to renilla luciferase values. For Figure 1A-1C, the following variation of the method was used:

[00619] HEK cells were plated in 24 well plates at 60,000 cells per well in DMEM + 5% csFBS without phenol red. After overnight incubation, changed medium to OptiMEM (0.25 ml). All the wells were transfected with 0.25 ug GRE-LUC, 5 ng CMV-renilla LUC, and 25 ng CMV-hAR. Twenty four h

red. Twenty-four hrs after transfection, the cells were treated with 20, 18, and 14 (Figure 1A), 12 and 11 (Figure 1B), 11, 27, and 23 (Figure 1C), or 34-42 (Figures 29A, 29B, 29D-29I, 29K, & 29O) and were harvested 48 hrs after transfection and firefly and renilla luciferase assay performed.

[00620] Transactivation. HEK-293 cells were plated at 120, 000 cells per well of a 24 well plate in DME+5% csFBS. The cells were transfected using Lipofectamine (Invitrogen, Carlsbad, CA) with 0.25 µg GRE-LUC, 0.01 µg CMV-LUC (renilla luciferase) and 25 ng of the AR, PR, GR, or MR. The cells were treated 24 hrs after transfection as indicated in the figures and the luciferase assay performed 48 hrs after transfection. Data are represented as IC50 values obtained from four parameter logistics curve. AR Degradation Using Compounds of this Invention

[00621] Objective: To determine the efficacy and potency of AR degradation by SARD compounds in AD1 cells (full-length), LNCaP (T877A AR), D567es (splice variant lacking exons 5,6,&7) or 22RV-1 (full length AR and truncated splice variant AR (AR-V7)) cell lines.

[00622] Method: See Example 6 below.

Determination of metabolic stability (in vitro CLint) of test compounds:

Phase I metabolism

[00623] The assay was done in a final volume of 0.5 ml in duplicates (n=2). Test compound (1mM) was pre-incubated for 10 minutes at 37ºC in 100 mM Tris-HCl, pH 7.5 containing 0.5 mg/ml liver microsomal protein. After pre-incubation, reaction was started by addition of 1 mM NADPH (pre- incubated at 37ºC). Incubations were carried out in triplicate and at various time-points (0, 5, 10, 15, 30 and 60 minutes) 100 ml aliquots were removed and quenched with 100 ml of acetonitrile containing internal standard. Samples were vortex mixed and centrifuged at 4000 rpm for 10 minutes. The supernatants were transferred to 96 well plates and submitted for LC-MS/MS analysis. As control, sample incubations done in absence of NADPH were included. From %PCR (% Parent Compound Remaining), rate of compound disappearance is determined (slope) and in vitro CL int (ml/min/mg protein) was calculated.

Metabolic stability in Phase I & Phase II pathways

[00624] In this assay, test compound was incubated with liver microsomes and disappearance of drug was determined using discovery grade LC-MS/MS. To stimulate Phase II metabolic pathway (glucuronidation), UDPGA and alamethicin was included in the assay. [00625

using LC-MS/MS system consisting of Agilent 1100 HPLC with an MDS/Sciex 4000 Q-Trap™ mass spectrometer. The separation was achieved using a C 18 analytical column (Alltima TM , 2.1 X 100 mm, 3 µm) protected by a C 18 guard cartridge system (SecurityGuard™ ULTRA Cartridges UHPLC for 4.6mm ID columns, Phenomenex). Mobile phase was consisting of channel A (95% acetonitrile + 5% water + 0.1% formic acid) and channel C (95% water + 5% acetonitrile + 0.1% formic acid) and was delivered at a flow rate of 0.4 mL/min. The volume ratio of acetonitrile and water was optimized for each of the analytes. Multiple reaction monitoring (MRM) scans were made with curtain gas, collision gas, nebulizer gas, and auxiliary gas optimized for each compound, and source temperature at 550°C. Molecular ions were formed using an ion spray voltage (IS) of -4200 V (negative mode). Declustering potential, entrance potential, collision energy, product ion mass, and cell exit potential were optimized for each compound.

[00626] Log P: Octanol-Water Partition Coefficient (Log P)

[00627] Log P is the log of the octanol-water partition coefficient, commonly used early in drug discovery efforts as a rough estimate of whether a particular molecule is likely to cross biological membranes. Log P was calculated using ChemDraw Ultra version is 12.0.2.1016 (Perkin-Elmer, Waltham, Massachusetts 02451). Calculated Log P values are reported in Tables 3 & 6 in the column labeled Log P (-0.4 to +5.6). Lipinski’s rule of five is a set of criteria intended to predict oral bioavailability. One of these criteria for oral bioavailability is that the Log P is between the values shown in the column heading (-0.4 (relatively hydrophilic) to +5.6 (relatively lipophilic) range), or more generally stated <5. One of the goals of SARD design was to improve water solubility. [00628] Table 1: AR Binding, Inhibition of AR (wt and Mutant) Transactivation, AR Degradation and in vitro Metabolic Stability of Indole and Benzimidazole SARDs.

[00629] The short half-lives (t1/2) and high metabolic clearance (CLint) values in vitro of many of the compounds of this invention suggest rapid plasma clearance which could be favorable for topical treatment of androgenic dermatologic disorders as it would limit the risk of systemic side effects, even if the skin is penetrated.

[00630] AR transactivation assay was performed with wildtype, W741L, and T877A AR constructs. W741 mutation to leucine or cysteine (L/C) confers resistance to bicalutamide (Hara, T., Miyazaki, J., Araki, H., Yamaoka, M., Kanzaki, N., Kusaka, M., and Miyamoto, M. (2003). Novel mutations of androgen receptor: a possible mechanism of bicalutamide withdrawal syndrome. Cancer Research 63, 149-153), while T877 mutation results in resistance to hydroxyflutamide (Tan, J., Sharief, Y., Hamil, K.G., Gregory, C.W., Zang, D.Y., Sar, M., Gumerlock, P.H., deVere White, R.W., Pretlow, T.G., Harris, S.E., et al. (1997). Dehydroepiandrosterone activates mutant androgen receptors expressed in the androgen-dependent human prostate cancer xenograft CWR22 and LNCaP cells. Mol Endocrinol 11, 450-459).11 potently inhibited the R1881-induced wildtype AR transactivation with much higher potency than enzalutamide (Figure 37A). While 11 effectively antagonized both wildtype and mutant ARs comparably, similar to enzalutamide, was weaker in W741L mutant AR (Figures 37B). Although 11 inhibited glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) transactivation only at ~10 mM, it cross-reacted with the progesterone receptor (PR) robustly (Figure 37C). [00631] Kennedy’s disease is a neuromuscular disease caused by AR with an extended polyglutamine tract (La Spada, A.R., Wilson, E.M., Lubahn, D.B., Harding, A.E., and Fischbeck, K.H. (1991). Androgen receptor gene mutations in X-linked spinal and bulbar muscular atrophy. Nature 352, 77-79). While in normal healthy humans, the AR contains 15-24 polyglutamines, in patients suffering from Kennedy’s disease, the polyglutamine tracts are extended to over 40 or even 100 repeats (La Spada et al., 1991). This extended polyglutamine tract results in AR mis-folding causing neuromuscular toxicity (La Spada et al., 1991).

[00632] 11 was tested in a transactivation assay with the AR containing an extended polyglutamine tract. 11 inhibited the R1881-stimulated transactivation of the AR that contains 65 polygl

AR.

[00633] AR N-C interaction is a measure of the AR activity (He et al., 2002) and inhibiting the AR N-C interaction is another measure of antagonistic activity. A mammalian two hybrid assay was performed with a Gal-4-DBD-fused AR-LBD, VP16 activation domain fused AR-NTD, and a dose response of 11.11 inhibited the R1881-induced AR N-C interaction at concentrations comparable to that observed in AR transactivation (Figure 37E). [00634] Table 2: Binding Affinity of Indole SARDs of this Invention.

[00635] Figure 1A-1C and Figures 29A-29O and Tables 1-3 show that many of the SARDs of this invention had higher AR binding affinity (see tables) and more potent AR antagonism in vitro (see Tables 1-4 and figures referenced above and in the tables) than all the other AR antagonists tested (bicalutamide, enzalutamide, ARN-509, and ASC-J9). Further compounds 11(Table 1 above) and 96 (Table 10 of Example 10) retained highly potent antagonist activity in the two resistance mutants tested unlike the known antiandrogens tested. P-78883-PC

The cells were treated 24 hrs after transfection as indicated in the figures and the luciferase assay performed 48 hrs after transfection. Data are represented as IC 50 obtained from four parameter logistics curve.

LNCaP gene expression assay.

[00646] Method: LNCaP cells were plated at 15,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Forty-eight hours after plating, cells were treated with a dose response of SARDs. Twenty four hours after treatment, RNA was isolated using cells-to-ct reagent, cDNA synthesized, and expression of various genes was measured by realtime rtPCR (ABI 7900) using taqman primers and probes. Gene expression results were normalized to GAPDH.

LNCaP growth assay.

[00647] Method: LNCaP cells were plated at 10,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Cells were treated with a dose response of SARDs. Three days after treatment, cells were treated again. Six days after treatment, cells were fixed and cell viability was measured by SRB assay.

LNCaP or AD1 degradation.

[00648] Method: LNCaP or AD1 cells expressing full length AR were plated at 750,000- 1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed to RPMI + 1% csFBS without phenol red and maintained in this medium for 2 days. Medium was again changed to RPMI + 1% csFBS without phenol red and cells were treated with SARDs (1 nM to 10 µM) in combination with 0.1 nM R1881. After 24 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt- containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody from SantaCruz and actin antibody from Sigma.

22RV1 and D567es degradation.

[00649] Method: 22RV1 and D567es cells expressing AR splice variants were plated at 750,000- 1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed and treated. After 24-30 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS- PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N- 20 antibody from SantaCruz and actin antibody from Sigma.

22RV1 growth and gene expression.

[00650] Methods: Cell growth was evaluated as described before by SRB assay. Cells were plated in a 96 well plate in full serum and treated for 6 days with medium change after day 3. Gene expression studies were performed in 22RV1 cells plated in 96 well plate at 10,000 cells/well in RPMI + 10% FBS. Twenty four hours after plating, cells were treated for 3 days and gene expression studies were performed as described before. Determination of metabolic stability (in vitro CL int ) of test compounds (Table 7)

Phase I metabolism

[00651] The assay was done in a final volume of 0.5 ml in duplicates (n=2). Test compound (1 mM) was pre-incubated for 10 minutes at 37ºC in 100 mM Tris-HCl, pH 7.5 containing 0.5 mg/ml liver microsomal protein. After pre-incubation, reaction was started by addition of 1 mM NADPH (pre-incubated at 37ºC). Incubations were carried out in triplicate and at various time-points (0, 5, 10, 15, 30 and 60 minutes) 100 ml aliquots were removed and quenched with 100 ml of acetonitrile containing internal standard. Samples were vortex mixed and centrifuged at 4000 rpm for 10 minutes. The supernatants were transferred to 96 well plates and submitted for LC-MS/MS analysis. As control, sample incubations done in absence of NADPH were included. From %PCR (% Parent Compound Remaining), rate of compound disappearance is determined (slope) and in vitro CL int (ml/min/mg protein) was calculated. Metabolic stability in Phase I & Phase II pathways

[00652] In this assay, test compound was incubated with liver microsomes and disappearance of drug was determined using discovery grade LC-MS/MS. To stimulate Phase II metabolic pathway (glucuronidation), UDPGA and alamethicin was included in the assay. LC-MS/MS analysis:

[00653] The analysis of the compounds under investigation was performed using LC-MS/MS system consisting of Agilent 1100 HPLC with an MDS/Sciex 4000 Q-Trap™ mass spectrometer. The separation was achieved using a C 18 analytical column (Alltima TM , 2.1 X 100 mm, 3 µm) protected by a C18 guard cartridge system (SecurityGuard™ ULTRA Cartridges UHPLC for 4.6mm ID columns, Phenomenex). Mobile phase was consisting of channel A (95% acetonitrile + 5% water + 0.1% formic acid) and channel C (95% water + 5% acetonitrile + 0.1% formic acid) and was delivered at a flow rate of 0.4 mL/min. The volume ratio of acetonitrile and water was optimized for each of the analytes. Multiple reaction monitoring (MRM) scans were made with curtain gas, collision gas, nebulizer gas, and auxiliary gas optimized for each compound, and source temperature at 550°C. Molecular ions were formed using an ion spray voltage of -4200 V (negative mode). Declustering potential, entrance potential, collision energy, product ion mass, and cell exit potential were optimized for each compound.

[00655] The short half-lives (t 1/2 ) and high metabolic clearance (CL int ) values in vitro of some of the compounds of this invention suggest rapid plasma clearance for those compounds which could be favorable for topical treatment of androgenic dermatologic disorders as it would limit the risk of systemic side effects, even if the skin is penetrated. Other compounds demonstrate relatively long half-lives and low metabolic clearances values in vitro suggesting that these compounds may be able to achieve systemic exposures necessary to have systemic antiandrogen effects such as would be necessary to treat prostate cancer.

AR Degradation Using Compounds of this Invention (indoles, benzimidazoles, indazoles) LNCaP Gene Expression Assay

[00658] Objective: To determine the effect of SARDs on AR-target gene expression in LNCaP cells.

[00659] Method: LNCaP cells were plated at 15,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Forty-eight hours after plating, cells were treated with a dose response of SARDs. Sixteen-twenty four hours after treatment, RNA was isolated using cells-to-ct reagent, cDNA synthesized, and expression of various genes was measured by realtime rtPCR (ABI 7900) using taqman primers and probes. Gene expression results were normalized to GAPDH.

LNCaP Growth Assay

[00660] Objective: To determine the effect of SARDs on LNCaP cell growth.

[00661] Method: LNCaP cells were plated at 10,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Cells were treated with a dose response of SARDs. Three days after treatment, cells were treated again. Six days after treatment, cells were fixed and cell viability was measured by SRB assay. LNCaP Degradation Assay

[00662] Objective: To determine the effect of SARDs on AR expression in LNCaP cells.

[00663] Method: LNCaP cells were plated at 750,000-1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed to RPMI + 1% csFBS without phenol red and maintained in this medium for 2 days. Medium was again changed to RPMI + 1% csFBS without phenol red and cells were treated with SARDs (1 nM to 10 µM) in combination with 0.1 nM R1881. After 16-20 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS- PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N- 20 antibody from SantaCruz and actin antibody from Sigma. 22RV-1 Degradation Assay

[00664] Objective: To determine the effect of SARDs on AR full length and splice variant expression in 22RV-1 cells.

[00665] Method: 22RV-1 cells were plated at 750,000-1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed and treated. After 16-20 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody from SantaCruz and actin antibody from Sigma. AD1 androgen receptor degradation (full length AR)

[00666] Objective: To deternube the effect of compounds of this invention (SARDs) on full length AR protein expression in AD1 cells.

[00667] Method: AD1 cells expressing full length AR were plated at 750,000-1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, the medium was changed to RPMI + 1% csFBS without phenol red and maintained in this medium for 2 days. The medium again was changed to RPMI + 1% csFBS without phenol red and cells were treated with SARDs (1 nM to 10 mM) in combination with 0.1 nM R1881. After 24 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three freeze-thaw cycles. The protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody (SantaCruz Biotechnology, Inc., Dallas, Texas 75220) and actin antibody (Sigma-Aldrich, St. Louis, MO). The results of this assay in AD1 cells were reported in Figures 33A (76), 33B (75), 33C (96) and 33D (97) as images of Western blot films (chemiluminescence exposed films). Also reported in Figures 33A-33D are results from wt AR binding (Ki), inhibition of transactivation (IC50), and in vitro metabolic stability in mouse liver microsomes (MLM). One advantage of the indazole template is metabolic stability in vitro compared to indole and benzimidazole analogs. For example, 96 (4-CF 3 indazole) demonstrated a half-life of 53.7 minutes and intrinsic clearance of 12.91 µg/min/mg which is a two-fold improvement compared to 18 (5-CF 3 indole; 21 min and 32.9 µg/min/mg).

[00668] Figure 2A presents degradation in LNCaP cells using 11 and 20. LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free condition for 3 days. The cells were treated as indicated in the figure, harvested, protein extracted, and Western blotted for AR. 11 demonstrated selective degradation of AR (i.e., SARD activity) in the nM range, i.e., at concentrations comparable to its antagonist IC50 value. LNCaP cells are known to express the AR mutant T877A, demonstrating the ability to degrade resistance conferring mutant androgen receptors.

[00669] Figure 2B presents the effect of AR antagonists and SARDs on LNCaP cell growth: LNCaP cells were plated in 96 well plates at 10,000 cells/well in RPMI + 1% csFBS without phenol red. Cells were treated as indicated in the figure in combination with 0.1 nM R1881 for 6 days with medium change on day 3. At the end of 6 days, the cells were fixed and stained with sulphorhodamine blue stain. 11 demonstrated more potent anti-proliferative activity in LNCaP cells at 1 and 10 µM when compared to enzalutamide and ARN-509.

[00670] Figure 3 presents AR-V7 degradation (PC3-AR-V7 cells) using 11, 12 and 20 at 1 µM and 10 µM. PC-3 prostate cancer cells were serum stably transfected with a lentivirus construct for AR-V7. Once the stable cells were selected, the cells were plated in 6 well plates at 1 million cells/well. The cells were treated as indicated in the figure and Western blot performed for AR and actin. The results show that the SARDs have the potential to degrade the truncated version of AR, while enzalutamide or ARN-509 had no effect of the AR-V7 expression. SARD compounds of this invention degrade AR-SV in 22RV-1 cells

[00671] Figure 4 - 22RV-1 Western blot: 22RV-1 cells were plated in 6 well plate at 1-1.5 million cells/well in growth medium (RPMI + 10% FBS). Next day, medium was changed and treated with vehicle or a dose response of 20. After overnight treatment (12-16 hrs), cells were washed in ice cold PBS and harvested by scrapping in 1 mL PBS. Cells were pelleted, protein extracted, quantified using BCA assay, and equal quantity of protein was fractionated on a SDS-PAGE. The proteins were transferred to nylon membrane and Western blotted with AR antibody (N20 from SCBT) and actin antibody. 20 was capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR- SV) in 22RV-1 cells, suggesting that SARDs may be able to overcome AR-V7 dependent prostate cancers (e.g., CRPC). 11 degraded AR-FL but not actin in LNCaP cells (Figure 5) and AR-FL and AR-SV in 22RV-1 cells (Figures 6A-6C). Figures 6A-6C show that 11 degraded AR-FL and AR- V7 at nM concentrations (Figure 6C) whereas ARN-509 did not degrade either (Figure 6B). Although ASC-J9 did exhibit some degradation in the nM range, µM concentrations failed to degrade AR (Figure 6A). 11 also inhibited AR-dependent gene expression (PSA and TMPRSS2) in LNCaP cells, transactivation of AR in 22RV-1 cells and cellular growth in both the cell types (Table 8 and Table 9). Cumulatively, these observations suggest that SARDs of this invention may be useful in prostate cancers that are dependent on mutant ARs, AR-FL and/or AR-SV.

[00672] Figure 11 presents degradation in LNCaP cells using 27, 20, 12, 23 and 32. LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free conditions for 3 days. The cells were treated as indicated in the figure, harvested, protein extracted, and Western blotted for AR. All SARDs demonstrated selective degradation of AR (i.e., SARD activity) at concentrations comparable to their antagonist IC 50 values. LNCaP cells are known to express the AR mutant T877A, demonstrating the ability to degrade antiandrogen resistance conferring mutant androgen receptors (i.e., advanced prostate cancers and CRPC).

[00673] Figure 12: 22RV-1 Western blot: 22RV-1 cells were plated in 6 well plates at 1-1.5 million cells/well in growth medium (RPMI + 10% FBS). Next day, medium was changed and treated with vehicle or a dose response of 20, 24 and 30. After overnight treatment (12-16 hrs), cells were washed in ice cold PBS and harvested by scrapping in 1 mL PBS. Cells were pelleted, protein extracted, quantified using BCA assay, and equal quantity was fractionated on a SDS-PAGE. The proteins were transferred to nylon membrane and Western blotted with AR antibody (N20 from SCBT) and actin antibody. 20, 24 and 30 were capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR-V7) in 22RV-1 cells, suggesting that SARDs may be able to overcome AR-V7 dependent prostate cancers (i.e., CRPC).

[00674] Figure 13 presents degradation in LNCaP cells and 22RV-1 cells using 31 vs. galeterone. The experiments were performed by the methods cited above. A dose response of SARD 31 demonstrated the ability to degrade full length AR in LNCaP and 22RV-1 cell lines, whereas galeterone was not able to substantially degrade AR in either cell line. [00675] Figure 14 presents degradation in LNCaP cells using 12 vs. ARN-509. 12 and ARN- 509 both demonstrated the ability to degrade AR in LNCaP cells, however 12 demonstrated activity at 1 µM whereas ARN-509 only demonstrated activity at 10 µM.

[00676] Figure 15 presents degradation in 22RV-1 cells using 31. Using the methods described in the legend for Figure 12 (22RV-1), SARD activity for 31 was demonstrated as degradation of full length (AR) and truncated splice variant (AR-V7) androgen receptor.

[00677] Figure 16 presents degradation in LNCaP cells using benzimidazoles 70 and 73. Using the methods described in the legend for Figure 11 (LNCaP), SARD activity for 70 and 73 was demonstrated at concentrations as low as 100 nM. This demonstrates that benzimidazoles of this invention also demonstrate potent SARD activity.

[00678] These selected SARD activity demonstrations as well of those reported in the tables suggest the compounds of this invention are able to degrade a variety of AR variants, and hence should provide the ability to inhibit the AR-axis activity whether it is androgen-dependent or androgen-independent. Degradation of the AR removes the possibility of promiscuous activation of mutant ARs, activation by intracellular processes such as signal transduction, kinase activation, and/or high levels of coactivators, etc.; and suggests that the SARDs should also degrade the polyQ polymorphisms in hyperandrogenic dermatologic disorders (shortened polyQ) or Kennedy’s disease (extended polyQ), providing a rationale for treating either type of disease by destroying the AR in the affected tissues (skin and neuromuscular system, respectively). [00679] Table 8: Inhibition of Growth and Gene Expression of LNCaP PCa Cells.

[00680] Table 9: Effects of SARDs on AR Transactivation and Growth of 22RV-1 Cells.

[00681] To validate the results obtained in 22RV1 cells, AR degradation effect of 11 was tested in various PCa cell lines. AD-1 cells that express only AR-FL, D567es cells that express only AR- v567es, and LNCaP-95 cells that co-express AR-FL and AR-SV (Figure 38A) were treated under various conditions with a dose response of 11. Cells were harvested 24 hrs after treatment and Western blot for the AR and its isoforms was performed. As indicated in the figures, 11 consistently degraded the AR and its SVs at concentrations ranging between 100 and 1000 nM, indicating that these SARDs degrade the AR and its SVs under various conditions and irrespective of the specific combination of the AR-FL and SV expressed. The D567es result was unexpected based on our hypothesis of SARD binding solely to the LBD, and earlier findings [Watson, P.A., Chen, Y.F., Balbas, M.D., Wongvipat, J., Socci, N.D., Viale, A., Kim, K., and Sawyers, C.L. (2010) Constitutively active androgen receptor splice variants expressed in castration-resistant prostate cancer require full-length androgen receptor. Proceedings of the National Academy of Sciences of the United States of America 107, 16759-16765) that the AR-SV function depends on the AR. The D567es result argues for the direct interaction of the SARDS of this invention with AR-SV such as D567es which lacks themLBD.

[00682] To determine if the degradation is a direct effect due to destabilization of already synthesized AR protein, LNCaP and 22RV1 cells were treated with 11, protein synthesis inhibitor cycloheximide, or a combination of cycloheximide and 11. While 11 degraded the AR and AR-V7 starting from 4-6 hrs, addition of cycloheximide accelerated the degradation, indicating that the 11- dependent AR and AR-SV degradation was not dependent on the expression of other proteins and that 11 destabilized the already synthesized AR and AR-SV (Figure 38B) at the protein level. The graph below Figure 38B shows the reduction in half-life of both the AR and AR-SV by 11.

[00683] Degradation of the AR and AR-V7 by 11 was rapid and sustained. To evaluate the time- course of degradation, LNCaP cells were treated with 11 in combination with 0.1 nM R1881. Cells were harvested at different time-points and Western blot for AR and actin was performed.11 degraded the AR starting at 4 hrs with complete degradation observed by 12 hrs (Figure 39A). Almost comparable time-course was followed for the inhibition of AR function as measured by the expression of the AR-target genes PSA and FKBP5 (Figure 39B). To determine the endurance of this degradation upon removal of 11, D567es cells were treated with vehicle or 11 for 24 hrs. Cells were washed and one set of plates was harvested immediately (time point 0 hrs), while the rest of the plates were harvested 24 or 72 hrs after the drug removal. Western blot for AR-V7 and actin was performed. AR was degraded by 11 by 24 hrs (time-point 0 hrs) and remained degraded up to 72 hrs after the 11 removal (Figure 39C).

[00684] 11 degraded the AR through ubiquitin-proteasome degradation machinery. To evaluate the role of ubiquitin-proteasome machinery in the SARD-dependent AR degradation, LNCaP cells were treated with 11 for 4 hrs, AR was immunoprecipitated, and a Western blot for ubiquitin was performed (Figure 38C). AR co-immunoprecipitated with ubiquitin in the presence of 11, indicating that ubiquitination of the AR in response to these SARDs is a potential mechanism for AR degradation.

[00685] 11 inhibited AR-dependent gene expression and PCa cell proliferation. To evaluate whether the highly potent AR antagonism translates to inhibition of AR function and PCa cell proliferation, 11 was tested in LNCaP cells and compared to enzalutamide. Treatment of LNCaP cells with 11 inhibited 0.1 nM R1881-induced PSA and FKBP5 gene expression at low nanomolar concentrations with at least 10-fold better potency than enzalutamide (Figure 40A).

[00686] To determine the effect of 11 on AR-V7-dependent gene expression, PC-3 cells stably transfected with AR-V7 were treated with vehicle or 10 mM 11 for 24 hrs and RNA-sequencing was performed. Expression of several genes was altered by AR-V7, which were reversed back to PC-3- GFP cell levels by 11 (Figure 40B left panel; selected genes from the list shown in Figure 40B right panel). These results show that the genes induced by AR-V7 were inhibited by 11. The effect on AR- V7-dependent gene expression was confirmed in 22RV1 cells, where androgen-independent expression of FKBP5 was inhibited by 11, but not by enzalutamide (Figure 40C).

[00687] The effect of the SARD compounds of this invention on the proliferation of AR-FL- and AR-SV-expressing cell lines was evaluated. R1881-induced LNCaP proliferation was completely inhibited by 11 with nanomolar IC 50 , while enzalutamide inhibited the proliferation at concentrations greater than 1 µM (Figure 40D).11 also inhibited the proliferation of 22RV1 cells at concentrations between 1 and 10 mM, while enzalutamide failed to inhibit the proliferation (Figure 40D). These results were reproduced in various cell lines, including LNCaP-abl and LNCaP-EnzR, both containing enzalutamide-resistant AR, and in AR-SV-expressing LNCaP-95 cells. 11 modestly inhibited the proliferation of HeLa cells at 30 mM, demonstrating its specificity. In addition to these cells, 11 also inhibited the proliferation of AD-1 (Figures 41A) and transactivation of v567es AR and proliferation of D567es cells that carry AR-v567es (Figure 41B). 11, but not enzalutamide, inhibited the expression of PSA in LNCaP-EnzR, indicating that the F876L mutant that is resistant to enzalutamide is sensitive to 11 (Figure 40E). [00688] The SARDs compounds of this invention inhibited the AR nuclear translocation and recruitment to PSA regulatory regions. To determine if the SARD compounds inhibit the recruitment of the AR to cis regulatory elements, LNCaP cells were treated with 11 in the presence of 0.1 nM R1881. Two hours after the treatment, cells were fixed to cross-link the protein to DNA, AR was immunoprecipitated, and recruitment to the PSA enhancer was quantified by realtime PCR. 11 inhibited the recruitment of the AR to PSA enhancer (Figure 42A). These studies were performed at a time-point when no AR degradation could be detected.

[00689] Inhibition of AR DNA binding could be a result of nuclear translocation inhibition. Microscopic evaluation of nuclear translocation shows that 11 inhibited the R1881-induced translocation of F876L enzalutamide-resistant AR (Figure 42B). [00690] The SARD compounds of this invention did not require binding to the LBD to degrade the AR. As these SARDs bind to two domains and degrade the AR, they serve as a tool to probe into the role of each domain for degradation and proliferation. Molecular modeling was performed to determine the amino acids in the AR-LBD with which 11 interacted.11 formed hydrogen bonds with Q711, R752, N705, and L704 (Figure 42C). These sites were mutated and performed a transactivation assay. Mutating these amino acids individually compromised the ability of R1881 to activate the AR. While the EC 50 of R1881 for the wildtype AR was 0.11 nM, the EC 50 for the mutant ARs was 7.48 nM for Q711A, 8.72 nM for L704A, 15.41 nM for R752L, and 2037 nM for N705A (Figure 42C; left panel).

[00691] The effect of 11 was determined on the transactivation of wildtype and mutants AR’s. In these studies R1881 was used at the respective EC50 for each mutant. While 11 effectively inhibited the wildtype AR transactivation at 63 nM, it inhibited the transactivation of the LBD mutants at concentrations greater than 1 mM.11 failed to inhibit the function of N705A mutant AR (Figure 42C; right panel). These studies show that mutating the interacting amino acids in the LBD weaken 11’s ability to inhibit ligand-dependent AR transactivation and that 11’s binding to LBD is important to antagonize androgen-dependent function of the AR.

[00692] To determine if mutating the LBD will also impact 11’s degradation role, HeLa cells transfected with wildtype or mutant ARs were treated with 11 and AR expression was evaluated by Western blot. These studies were performed under the same conditions as indicated for the transactivation.11 degraded the wildtype and mutant ARs comparably (Figure 42D), indicating that binding to LBD can be spared to retain the degradation activity. [00693] To confirm this observation the R-isomer of 11 was synthesized (11R).11 has a chiral center and the active form is the S-isomer. Hence, an R-isomer is expected to be a weaker LBD binder than the S-isomer. We tested the effect of 11R on R1881-induced AR transactivation and AR expression. While the 11R was 10-fold weaker to inhibit the AR transactivation, no difference was observed between the S- and R- isomers of 11 in their ability to degrade the AR (Figure 43).

[00694] To determine if 11’s anti-proliferative effect is dependent on its competitive binding to the LBD, we performed proliferation assay in LNCaP cells in the presence of increasing concentrations of R1881. We expected that increasing concentration of R1881 will displace 11 from the ligand binding pocket, resulting in reduced or lack of anti-proliferative effects. Interestingly, increasing concentrations of R1881 weakened enzalutamide’s effects, but failed to affect 11’s effect on proliferation (Figure 44) suggesting that anti-proliferative effects are not dependent of competitive binding to the LBD.

[00695] Collectively these studies provide compelling evidence to show that 11 elicits AR degradation and possibly anti-proliferative activity through its AF-1, while the antagonistic effect of ligand-dependent transactivation is through the LBD. [00696] 11 inhibited PCa xenografts growth. In vitro studies proved that 11 were extremely potent to inhibit and degrade both AR and AR-SVs.11 was tested in vivo in various xenograft models. In addition to LNCaP and 22RV1 xenografts, we developed a PDX, Pr-3001, from a CRPC patient specimen. Pr-3001 is a CRPC that expresses AR-FL and AR-SV and grows in castrated mice. [00697] Pr-3001 is an aggressively growing patient-derived specimen. Typically, it is very hard to grow patient-derived PCa in mice due to their slow growing property. Pr-3001 developed tumors robustly and attained approximately 1000 mm 3 in less than 2 months. Pr-3001 expresses AR-FL and AR-SV and grows in castrated mice. Pr-3001 at 1 mm 3 piece were implanted on the flanks of mice and its growth was monitored. When Pr-3001 attained 100-200 mm 3 , the animals were randomized and treated with vehicle or 11. Consistent with the observations made in 22RV1 xenograft, 11 inhibited the growth Pr-3001 by over 50% (Figure 45). EXAMPLE 8 AR Degradation Using Indoline, Quinoline, or Isoquinoline SARD Compounds of this

Invention Plasmid constructs and transient transfection.

[00698] Human AR cloned into CMV vector backbone was used for the transactivation study. HEK-293 cells were plated at 120,000 cells per well of a 24 well plate in DME + 5% csFBS. The cells were transfected using Lipofectamine (Invitrogen, Carlsbad, CA) with 0.25 µg GRE-LUC, 0.01 µg CMV-LUC (renilla luciferase) and 25 ng of the AR. The cells were treated 24 hrs after transfection as indicated in the figures and the luciferase assay performed 48 hrs after transfection. Data are represented as IC 50 obtained from four parameter logistics curve.

Ligand binding assay.

[00699] hAR-LBD (633-919) was cloned into pGex4t.1. Large scale GST-tagged AR-LBD was prepared and purified using a GST column. Recombinant ARLBD was combined with [ 3 H]mibolerone (PerkinElmer, Waltham, MA) in buffer A (10 mM Tris, pH 7.4, 1.5 mM disodium EDTA, 0.25 M sucrose, 10 mM sodium molybdate, 1 mM PMSF) to determine the equilibrium dissociation constant (Kd) of [ 3 H]mibolerone. Protein was incubated with increasing concentrations of [ 3 H]mibolerone with and without a high concentration of unlabeled mibolerone at 4ºC for 18 h in order to determine total and non-specific binding. Non-specific binding was then subtracted from total binding to determine specific binding and non-linear regression for ligand binding curve with one site saturation to determine the Kd of mibolerone.

[00700] Increasing concentrations of SARDs or DHT (range: 10 -12 to 10 -4 M) were incubated with [ 3 H]mibolerone and AR LBD using the conditions described above. Following incubation, the ligand bound AR-LBD complex was isolated using biogelHT hydroxyapatite, washed and counted in a scintillation counter after adding scintillation cocktail. Values are expressed as K i .

LNCaP gene expression assay.

[00701] Method: LNCaP cells were plated at 15,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Forty-eight hours after plating, cells were treated with a dose response of SARDs. Twenty four hours after treatment, RNA was isolated using cells-to-ct reagent, cDNA synthesized, and expression of various genes was measured by realtime rtPCR (ABI 7900) using taqman primers and probes. Gene expression results were normalized to GAPDH. LNCaP growth assay.

[00702] Method: LNCaP cells were plated at 10,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Cells were treated with a dose response of SARDs. Three days after treatment, cells were treated again. Six days after treatment, cells were fixed and cell viability was measured by SRB assay.

LNCaP or AD1 degradation.

[00703] Method: LNCaP or AD1 cells expressing full length AR were plated at 750,000- 1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed to RPMI + 1% csFBS without phenol red and maintained in this medium for 2 days. Medium was again changed to RPMI + 1% csFBS without phenol red and cells were treated with SARDs (1 nM to 10 µM) in combination with 0.1 nM R1881. After 24 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt- containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody from SantaCruz and actin antibody from Sigma.

22RV1 and D567es degradation.

[00704] Method: 22RV1 and D567es cells expressing AR splice variants were plated at 750,000- 1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed and treated. After 24-30 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS- PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N- 20 antibody from SantaCruz and actin antibody from Sigma. 22RV1 growth and gene expression.

[00705] Methods: Cell growth was evaluated as described before by SRB assay. Cells were plated in 96 well plate in full serum and treated for 6 days with medium change after day 3. Gene expression studies were performed in 22RV1 cells plated in 96 well plate at 10,000 cells/well in RPMI + 10% FBS. Twenty four hours after plating, cells were treated for 3 days and gene expression studies were performed as described before. Results:

[00706] Figure 18 presents degradation in LNCaP cells using 100 compared to ARN-509. LNCaP cells were plated in 6 well plates at 1 million cells/well. The cells were maintained in serum free conditions for 3 days. The cells were treated as indicated in the figure, harvested protein extracted, and Western blotted for AR. 100 demonstrated selective degradation of AR (i.e., SARD activity) in the nM range, i.e., at concentrations comparable to its antagonist IC 50 value whereas ARN-509 only demonstrated SARD activity at the highest concentration tested. LNCaP cells are known to express the AR mutant T877A, demonstrating the ability of compounds of this invention to degrade antiandrogen resistance conferring mutant androgen receptors.

[00707] Figure 19 demonstrates via Western blot that 100, 102, and 130 degraded AR-FL and AR-SV in 22RV-1 cells.22RV-1 cells were plated in 6 well plates at 1-1.5 million cells/well in growth medium (RPMI + 10% FBS). Next day, medium was changed and treated with vehicle or a dose response of 100, 102, and 130. After overnight treatment (12-16 hrs), cells were washed in ice cold PBS and harvested by scrapping in 1 mL PBS. Cells were pelleted, protein extracted, quantified using BCA assay, and equal quantity of protein was fractionated on a SDS-PAGE. The proteins were transferred to nylon membrane and Western blotted with AR antibody (N20 from SCBT) and actin antibody. 100, 102, and 130 were capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR-SV) in 22RV-1 cells, suggesting that SARDs may be able to overcome AR-V7 dependent prostate cancers.

[00708] Figure 20 presents degradation in 22RV-1 cells using 130 vs. galeterone. Using the methods described in the legend for Figure 19 (22RV-1), 130 was compared to galeterone (a clinical lead SARD). 130 demonstrated SARD activity in 22RV-1 (growth dependent on AR-SV, an AR variant lacking a LBD) cells which was comparable to galeterone.

[00709] Figure 21 presents degradation in LNCaP cells using 135 and 102. Using the methods described in the legend for Figure 18, SARD activities for 135 and 102 was demonstrated. These compounds partially and fully degraded mutant AR (T877A), suggesting that SARDs such as these may be useful in advanced prostate cancer and/or CRPC. [00710] Figure 22 presents degradation in LNCaP cells and 22RV-1 cells using 103 and 104. Using the methods described in the legends for Figure 18 (LNCaP) and Figure 19 (22RV-1), 103 and 104 demonstrated SARD activity in both LNCaP (mutant AR harboring T877A mutation) and 22RV- 1 (growth dependent on AR-SV lacking a LBD) cells.

[00711] Figure 23 presents degradation in 22RV-1 cells using 130. Using the methods described in the legend for Figure 19, compound 130 demonstrated SARD activity at least at the 10 µM concentration.

[00712] Figure 24 presents degradation in 22RV-1 cells using 134 and 130. Using the methods described in the legend for Figure 19, compounds 134 and 130 each demonstrated SARD activity at least at the 10 µM concentration.

[00713] Figure 25 presents degradation in LNCaP cells using -101, 105, 106, 107 and 108. LNCaP cells were plated in 6 well plates at 500,000 cells/well and maintained in RPMI + 1% csFBS without phenol red for 2 days. Cells were treated as indicated above in combination with 0.1 nM R1881 for 24 hrs. Cells were harvested 24 hrs after treatment, protein extracted, Western blotted with AR antibody (SantaCruz antibody AR N-20) and actin antibody (Sigma). 101, 105, 106, 107 and 108 each demonstrated the ability to degrade the AR in the nM range.

[00714] Figures 49A and 49B present degradation of FL AR and AR SV by selected SARDs. LNCaP (Figure 49A) or 22RV1 (Figure 49B) cells were plated in full-serum containing medium. Medium was changed to 1% charcoal-stripped serum containing medium and maintained in this medium for 2 days. Medium was changed again and the cells were treated with 0.1 nM R1881 (agonist) and either vehicle or a titration of SARD as indicated in the figure. Twenty-four hours after treatment, cells were harvested, protein extracted, and the proteins were blotted with AR-N20 antibody. Blots were stripped and re-probed with an actin antibody. AR- full length androgen receptor; AR-SV- androgen receptor splice variant. In Figures 49A and 49B, SARD activity was measured by treating cells with 0.1, 1.0 or 10 µM concentrations of SARDs in the presence of agonist (0.1 nM R1881). The Western blots were quantified densitometrically and the AR/Actin values are represented as fold change or percent change from vehicle-treated cells.

[00715] Figure 49A showed the degradation of FL AR in LNCaP cells and Figure 49B showed degradation of SV in 22RV1 cells, while actin in each lane serves as an internal standard to correct for variations in protein loading which complicate the visual interpretation of the immunoblots. The % degradation values reported in Tables 3 and 6 are normalized for variations in protein loading and are relied upon for relative efficacy determinations. Concentration-dependent degradation was seen in LNCaP cells for 115 (3’-Cl, 5-F, 6-Ph indoline), 34(3’-Cl, 5-F, 6-Ph indole), 101 (3’-CF3, 4- F indoline), 104 (3’-Cl, 5-F indoline) and 106 (3’-Cl, 6-F indoline). From Figure 49A, it is apparent that >50% of FL AR is already degraded at 1 µM of these SARDs, i.e. nM range SARD activity. SV AR degradation (the lower molecular weight band in Figure 49B; upper band is disregarded in % degradation values) of 34 (3’-Cl, 5-F, 6-Ph indole), 102, 115 (3’-Cl, 5-F, 6-Ph indoline), 103 (3’-Cl, 4-F indoline), and 11 (3’-CF3, 5-F indole) was observed to be dose- dependent and generally about 10-fold less potent (Figure 49B) for selected SARDs, which is consistent with other SARDs. Some compounds degrade FL AR better than SV AR (e.g., 106) or vice versa (e.g., 32) (Tables 3 and 6), whereas the optimal SARD potently and completely (i.e., ++++) degrades both and has a high potency antagonism. 115 comes closest to displaying the perfect profile with complete/strong degradation of FL/SV and antagonism comparable to enzalutamide, 0.244 µM (115) vs.0.216 µM (5).

[00716] These selected SARD activity demonstrations and well as other reported in the tables suggest the compounds of this invention are able to degrade a variety of AR variants, and hence should provide the ability to inhibit the AR-axis activity whether it is androgen-dependent or androgen-independent. Degradation of the AR removes the possibility of promiscuous activation of mutant ARs, activation by intracellular processes such as signal transduction, kinase activation, high levels of coactivators, etc.; and suggests that the SARDs should also degrade the polyQ polymorphisms in hyperandrogenic dermatologic disorders (shortened polyQ) or Kennedy’s disease (extended polyQ), providing a rationale for treating either type of diseases by destroying the AR in the affected tissues (skin and neuromuscular system, respectively). Further, a spectrum of in vitro metabolic stabilities were observed suggesting the possibility of either topical administration (short half-life such that systemic exposure are limited) or systemic (e.g., oral; requires relatively long half- lives) administration. EXAMPLE 9

SARDs Inhibit Ligand Independent AR Transcription [00717] Compound 11 inhibited transactivation in the AR-NTD-DBD-hinge (A/BCD) AR construct which lacks the ligand binding domain (Figures 7A-7D). (A.) AR A/BCD increased GRE- LUC reporter activity. AR A/BCD construct that lacks the ligand binding domain (labeled as A/BCD) or empty vector (labeled as pCR3.1) was transfected into HEK-293 cells along with GRE-LUC and CMV-renilla LUC. Forty eight hours after transfection cells were harvested and luciferase assay performed. As expected, the empty vector did not produce a strong signal compared to the A/BCD construct. (B.-D.) AR A/BCD activity was inhibited by 11. AR A/BCD construct that lacks the ligand binding domain (LBD) was transfected along with GRE-LUC and CMV-LUC. Cells were treated 24 hrs after transfection as indicated in the figure and luciferase assay performed 48 hrs after transfection. 11 (a SARD) inhibited the activity of construct lacking LBD confirming the binding to an alternate site in addition to the LBD. Non-SARD antagonists ARN-509 and enzalutamide did not inhibit the activity of this AR construct lacking the LBD, suggesting that SARDs can inhibit ligand independent AR activity via an alternative binding and degradation domain (BDD) located outside of the LBD. Subsequently, experiments have indicated the NTD as the location of this binding site (see Example 12). EXAMPLE 10

Comparison of SARDs and Clinical Candidates in Binding and Transactivation

[00718] Plasmid Constructs and Transient Transfection. Human AR cloned into CMV vector backbone was used for the transactivation study. HEK-293 cells were plated at 120,000 cells per well of a 24 well plate in DME + 5% csFBS. The cells were transfected using Lipofectamine (Invitrogen, Carlsbad, CA) with 0.25 mg GRE-LUC, 0.02 mg CMV-LUC (renilla luciferase) and 25 ng of the AR. The cells were treated 24 h after transfection as indicated in the figures and the luciferase assay performed 48 h after transfection. Data are represented as IC50 obtained from a four parameter logistics curve.

[00719] Figure 8A presents the data comparing 11, 12, and 14 with galeterone, EPI-001, and enzalutamide, in the transactivation study. In general the SARDs of this invention were equipotent to more potent than enzalutamde which was the most potent known AR antagonist tested. EPI-001 did not demonstrate any inhibition in this assay. Figure 8B shows the data comparing 11 with galeterone and enzalutamide in the transactivation study. The results show that the SARD compounds of the present invention were several-fold more potent than galeterone and enzalutamide in inhibition of DHT activated AR transactivation in vitro.

[00720] Figures 34-36 present data comparing compound 96 with enzalutamide, galeterone and ARN-509. Figure 34 presents the effect of known AR antagonists and SARD 96 on FKBP5. Figure 35 presents the effect of known AR antagonists and SARD 96 on PSA. Figure 36 presents the effect of AR antagonists and SARD 96 on SRB-LNCaP cell growth: LNCaP cells were plated in 96 well plates at 10,000 cells/well in RPMI + 1% csFBS without phenol red. Cells were treated as indicated in the figure in combination with 0.1 nM R1881 for 6 days with medium change on day 3. At the end of 6 days, the cells were fixed and stained with sulphorhodamine blue stain. Table 10 summarizes the above and presents it as a panel of in vitro characterizations of 96 with regard to AR binding (K i ), nuclear hormone receptor transactivation including AR wt and mutant (IC 50 ), and inhibition of LNCaP cell growth and AR-dependent gene expression in LNCaP cells. 96 binds to the LBD of AR with relatively low affinity (~1 µM) but inhibits AR transactivation in wildtype (301 nM) and T877A (343 nM) and W741L (14 nM) mutants with greater potency suggesting that AR inhibition may not be mediated by the LBD. 96 demonstrates good nuclear receptor specificity with no inhibition of transactivation in the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), and inhibition in the progesterone receptor (PR) that is 3-fold less potent than inhibition of the AR (wt). The anti-androgenic activity of 96 is also evidenced in LNCaP cells, a prostate cancer cell line whose growth is dependent on mutant T877A AR. 96 was anti-proliferative (Figure 36) and inhibited AR-dependent gene expression of FKBP5 (Figure 34) and PSA (Figure 35) in LNCaP cells demonstrating the potential for the treatment of prostate cancer with 96 and other SARDs of this invention based on their activity in well known models of prostate cancer such as LNCaP cells. This panel suggests that 96 is more potent in AR escape mutants than wt AR unlike the known AR antagonists tested, and more nuclear hormone receptor selective than the AR antagonists in use (enzalutamide) or advanced clinical testing (ARN-509 and galeterone).

[00722] Ligand binding assay. hAR-LBD (633-919) was cloned into pGex4t.1. Large scale GST-tagged AR-LBD was prepared and purified using a GST column. Recombinant AR-LBD was combined with [ 3 H]mibolerone (PerkinElmer, Waltham, MA) in buffer A (10 mM Tris, pH 7.4, 1.5 mM disodium EDTA, 0.25 M sucrose, 10 mM sodium molybdate, 1 mM PMSF) to determine the equilibrium dissociation constant (K d ) of [ 3 H]mibolerone. Protein was incubated with increasing concentrations of [ 3 H]mibolerone with and without a high concentration of unlabeled mibolerone at 4ºC for 18 h in order to determine total and non-specific binding. Non-specific binding was then subtracted from total binding to determine specific binding and non-linear regression for ligand binding curve with one site saturation to determine the K d of mibolerone.

[00723] Increasing concentrations of SARDs or DHT (range: 10 -12 to 10 -4 M) were incubated with [ 3 H]mibolerone and AR-LBD using the conditions described above. Following incubation, the ligand bound AR-LBD complex was isolated using BioGel HT hydroxyapatite, washed and counted in a scintillation counter after adding scintillation cocktail. Values are expressed as Ki. Table 11 shows that the SARD compounds of the present invention are at least approximately 8-10 folds more tightly bound than galeterone and enzalutamide in AR binding assay studies.

EXAMPLE 11

Compound 11 Inhibits Tumor Growth of an Aggressive Prostate Cancer Expressing AR

Splice Variant

[00725] Xenograft experiment. NOD SCID gamma (NSG) mice (n=8-10) were housed as five animals per cage and were allowed free access to tap water and commercial rat chow (Harlan Teklad 22/5 rodent diet - 8640). Cell line xenografts were performed as previously published (Narayanan et al., 2010; Yepuru et al., 2013). LNCaP tumors were grown in intact mice, while 22RV-1 tumors were grown in castrated mice. Once tumor size reached 100 mm 3 , the animals were randomized and treated with vehicle control (polyethylene glycol: DMSO 9:1 ratio) or 11 (50 mg/kg/day s.c.). Tumor volume was calculated using the formula length*width*width*0.5236. At the end of the experiment, animals were sacrificed, tumors were collected, weighed, and stored for further analysis. Blood was collected, serum separated, and serum PSA was measured using ELISA.

[00726] All experiments were performed thrice and each in vitro experiment was performed in triplicate. Statistical analysis was performed using JMP-Pro software (SAS; Cary, NC). Experiments containing only two groups were analyzed by simple t-test, while experiments containing more than two groups were analyzed by One Way ANOVA, followed by appropriate post-hoc test.

[00727] 22RV-1 xenograft studies with Compound 11: Since 11 degraded both AR-FL and AR-SV in 22RV-1 and LNCaP cells, the molecule was evaluated in 22RV-1 (Figures 9A-9D) and LNCaP (Figures 10A-10C) xenograft studies described below. Figures 9A-9B show that 11 (100 mg/kg bid) inhibited tumor growth of a prostate cancer that expresses an AR splice variant (AR-V7) and full-length AR (AR-FL). 22RV-1 is a highly aggressive tumor model that is unresponsive to any currenty available tratements. A SARD compound of the present invention, 11, restricted its growth by approximately 50%, whereas enzalutamide (Enzal) was ineffective. No side-effects were observed in the 3-4 weeks study. Figure 9C demonstrated that 11 degraded both AR-FL and AR-V7 in the 22RV-1 xenografts whereas enzalutamide (Enzalu) demonstrated no degradation of either AR in these xenografts. Figure 9D demonstrated that 11 but not enzalutamide suppressed serum PSA in xenograft bearing animals, demonstrating that 11 suppressed AR gene expression in these tumors. This demonstrated that 11 but not enzalutamide can overcome the antiandrogen resistance present in 22RV-1 cells (e.g., AR-V7 dependent growth) by degrading the AR-V7 and AR-FL, resulting in significantly suppressing androgenic tone in these tumors. This provided a proof-of-concept that SARDs such as 11 would be of clinical benefit to CRPC patients, particularly if systemic exposures could be improved.

[00728] Figures 10A-10C show that 11 (100 mg/kg bid) inhibited LNCaP tumor xenograft growth with a % tumor growth inhibition (%TGI) of 65% (Figure 10A) and inhibited tumor weight by about 50% (Figure 10B). As shown in Figure 10C, the serum PSA level was inhibited by >75%, indicating the AR-axis was suppressed in the xenograft as expected for a SARD. Cumulatively, these results indicated that SARDs should be effective in AR-driven prostate cancers regardless of whether the prostate cancers are driven by wt or mutant AR-FL and/or AR-SV such as AR-V7 which lack the LBD. As such SARDs, would be able to treat enzalutamide or abiraterone resistant prostate cancers. EXAMPLE 12

SARDs Bind to the AF1 of NTD of AR

[00729] Fluorescent Polarization (FP): There are two tryptophan residues and up to 12 tyrosine residues in the AF1 of the AR which is located in the N-terminal domain (NTD) of AR. This has allowed the study of the folding properties of this domain using intrinsic steady state fluorescence emission spectra. Excitation at 287 nm excites both tyrosine and tryptophan residues. The emission maximum (lmax) for the tryptophan is sensitive to the exposure to solvent. In the presence of the natural osmolyte TMAO there is a characteristic‘blue shift’ consistent with the tryptophan residues being less solvent exposed and a loss of the shoulder (~307 nm) for tyrosine as there is increased energy transfer to tryptophan as the polypeptide folds. To test if the compounds (a nonsteroidal agonist enobosarm (negative control), and the SARD 11) interact with AF-1 and/or alter the folding of this domain the steady state fluorescence was measured for each compound with AR-AF1 alone or the presence of TMAO (3 M) or the denaturant urea (4 or 6 M).1 µM of AR-AF1 and 5 µM of the individual compounds were used, and preincubated for at least 30 minutes prior to measuring the emission spectra. The emission spectra were all corrected for buffer alone or buffer with TMAO/urea/compounds as necessary. Figure 17A-C presents biophysical data that suggests that SARDs bind to the N-terminal domain of the AR (in addition to the LBD in the C-terminus reported as K i values herein). Figure 17A: Dose-dependent shift in the fluorescence intensity by 11 when incubated with AR AF-1. The fluorescence shoulder observed at 307 nm, which corresponds to tyrosine residues in the AF-1, is shifted by 11. Figure 17B: The overall fluorescence is also markedly altered by increasing concentrations of 11. Figure 17C: Data shown in Figure 17A was plotted as a difference in fluorescence between control and 11 treated samples (fluorescence in the absence of compound– fluorescence in the presence of compound), a dose dependent increase was observed in the presence of 11, consistent with binding to and stabilization of the intrinsically disordered AR-AF1 peptide derived from the NTD of AR. This data demonstrated binding of SARDs to the NTD domain. Only EPI-001 is reported to bind NTD but is not orally bioavailable. Enzalutamide and ARN-509 bind to the LBD only. This demonstrates the uniqueness of the compounds of this invention that are highly potent and selective androgen receptor degraders of a variety of full-length and splice-variant androgen receptors (Examples 5-8 and 13), potent inhibitors of LBD-dependent transactivation (Examples 5-8, 10, and 13), and inhibit NTD-dependent activity (Example 9) via binding to the NTD (Example 12). Based on their unique profile of AR antagonistic mechanisms, there is great expectation to expand the scope of diseases treatable with the androgen receptor antagonist compounds of this invention reported herein.

[00730] Based on half-maximum saturation for the change in fluorescence signal (at lmax 242 nm), the binding constant to AR-AF1 was calculated to be of KD=1.34 ±0.32 µM (n=3, mean ±SEM).

[00731] 1 µM AR-AF1 was pre-incubated without or with increasing concentrations of compound 11 (up to 15 µM) and steady-state fluorescence emission, after excitation at 287 nm, measured from 300 to 400 nm. Data was analysed as described by Epps et al (1999) J. Pharm 51, 41-48, Rawel et al (2006) Mol. Nutr. Food Res.50, 705-713 and Wang et al (2011) Mol. Endcor.25, 2041-2053 which are hereby incorporated by reference.

[00732] Surface Plasmon Resonance (SPR): To confirm the results obtained by FP assay, a biotin labeled method using AF-1 was employed. Biacore assay uses surface plasmon resonance (SPR) to measure protein-protein interaction and protein-small molecule interaction. In this assay, AR AF-1 and 50 nM of 11 were added to a Biacore chip and SPR was measured.11 demonstrated a change in the refraction index in the SPR, indicating an interaction with the AR AF-1 protein (Figure 47).

[00733] NMR studies confirm the binding of 11 to AF-1 between amino acids 244-360. 1 H NMR is consistently used in high-throughput screens to detect the binding of small molecules less than 500 Da to large proteins greater than 5 KDa [Dias, D.M., and Ciulli, A. (2014). NMR approaches in structure-based lead discovery: recent developments and new frontiers for targeting multi-protein complexes.

It is easier to use one-dimensional (1D) NMR to observe changes in line-width or line broadening as a high-throughput method to identify the binding of the molecules to proteins and then use two-dimensional (2D) NOE-based NMR techniques such as Water ligand- observed spectroscopy (WaterLOGSY) as confirmatory methodology [Dalvit, C., Pevarello, P., Tato, M., Veronesi, M., Vulpetti, A., and Sundstrom, M. (2000). Identification of compounds with binding affinity to proteins via magnetization transfer from bulk water. J Biomol NMR 18, 65-68; Shortridge et al., 2008].

[00734] All these experiments are based on the fact that NMR observables such as linewidths and NOE’s vary dramatically between small molecules and heavy molecules. The decreased rotational correlation times upon binding of a small molecule ligand to a heavy target molecule produce an atypical heavy molecule NMR result characterized by broadened and weaker of ligand peaks in 1D NMR and negative NOE peaks in the waterLOGSY as compared to the free state. In the absence of any affinity, the small molecule NMR result is obtained (sharp peaks in 1D NMR and positive NOE’s). This distinction provides the basis for NMR screening experiments. . [00793] Using these principles 1 H NMR was used to confirm the binding of 11 to AF-1 protein. In the first experiment, 11 or enzalutamide (500 mM) was dissolved in deuterated DMSO (DMSO-d6) and was incubated alone or mixed with 5 mM GST-AF-1 or GST and the binding of the molecules to the protein was determined by NMR. While 11 alone or in combination with GST exhibited sharp peaks revealing that the ligand was present in the free state, 11 in combination with GST-AF-1 provided a broadened and weaker peaks (Figure 46A; peaks in box) revealing that 11 has affinity for the AF-1 protein. Enzalutamide is a traditional AR antagonist known to competitively bind to the LBD. No line broadening was observed upon addition of enzalutamide to AF-1 revealing no affinity for AF-1. This result confirms that the 11, but not enzalutamide, binds to the AF-1 domain. To further confirm the 1D NMR results, we performed WaterLOGSY with 11 alone or in combination with AF- 1. While the 11 alone gave a flat signal, i.e., no negative NOE’s as expected for a free state small molecule, 11in combination with AF-1 provided a negative signal characteristic of binding to the protein (Figure 46B).

[00794] To determine precisely the region where 11 binds to the AF-1 region (since the AF-1 region is between 141 and 486 amino acids), we created smaller fragments of the AF-1 gene and purified the proteins coded for by fragments (Figure 46C).11 was incubated alone or in combination with GST, GST-AF-1 or with various fragments of the AF-1 region and 1D 1 H NMR profile was obtained. Similar to the results shown in Figure 46A, 11 provided a sharp signal by itself and when co-incubated with GST, but line broadening when incubated with the AF-1 (Figure 46D). Similar to the unbound ligand, 11 in combination with fragments 1A and 5T produced spectra suggestive of free state. However, when 11 was incubated with fragment 1T, the signal was almost indistinguishable from line, indicating a strong binding affinity to this region. The profile of 11 in combination with 1B looked similar to that of the AF-1, confirming the binding to this region. Binding of 11 to 1T and 1B, but not to 1A, indicates that amino acids 51-211 could be excluded and that potentially the binding occurs between amino acids 244 and 360.

[00795] Three separate biophysical phenomena, FP, SPR, and NMR indicate that 11

and other SARDs of this invention have significant affinity for AF-1, suggestive of binding strong enough to mediate some of the unique characteristics of the AR antagonists reported herein. EXAMPLE 13

Androgen Receptor Binding and Transactivation of Carbazole Based SARDs Ligand Binding Assay [00796] Objective: To determine SARDs binding affinity to the AR-LBD.

[00797] Method: hAR-LBD (633-919) was cloned into pGex4t.1. Large scale GST-tagged AR-LBD was prepared and purified using a GST column. Recombinant ARLBD was combined with [ 3 H]mibolerone (PerkinElmer, Waltham, MA) in buffer A (10 mM Tris, pH 7.4, 1.5 mM disodium EDTA, 0.25 M sucrose, 10 mM sodium molybdate, 1 mM PMSF) to determine the equilibrium dissociation constant (Kd) of [ 3 H]mibolerone. Protein was incubated with increasing concentrations of [ 3 H]mibolerone with and without a high concentration of unlabeled mibolerone at 4ºC for 18 h in order to determine total and non-specific binding. Non-specific binding was then subtracted from total binding to determine specific binding and non-linear regression for ligand binding curve with one site saturation to determine the Kd of mibolerone.

[00798] Increasing concentrations of SARDs or DHT (range: 10 -12 to 10 -2 M) were incubated with [ 3 H]mibolerone and AR LBD using the conditions described above. Following incubation, the ligand bound AR-LBD complex was isolated using BioGel HT® hydroxyapatite, washed and counted in a scintillation counter after adding scintillation cocktail. Values are expressed as Ki (Table 12). Transactivation Assay for wt and Mutant AR

[00799] Objective: To determine the effect of SARDs on androgen-induced transactivation of AR wildtype (wt) or AR carrying known AR-LB mutants (i.e., W741L or T877A).

[00800] Method: HEK-293 cells were plated at 125,000 cells/well of a 24 well plate in DME + 5% csFBS without phenol red. Cells were transfected with 0.25 ug GRE-LUC, 10 ng CMV-renilla LUC, and 50 ng CMV-hAR(wt) or CMV-hAR(W741L) or CMV-hAR(T877A) using Lipofectamine transfection reagent in optiMEM medium. Medium was changed 24 h after transfection to DME + 5% csFBS without phenol red and treated with a dose response of various drugs (Table 12: compounds 200-205) (1 pM to 10 ^M). SARDs and antagonists were treated in combination with 0.1 nM R1881. Luciferase assay was performed 24 h after treatment on a Biotek synergy 4 plate reader. Firefly luciferase values were normalized to renilla luciferase values. Transactivation Assay: wt and Mutant ARObjective:

[00802] Method: HEK-293 cells were plated at 125,000 cells/well of a 24 well plate in DME + 5% csFBS without phenol red. Cells were transfected with 0.25 ug GRE-LUC, 10 ng CMV-renilla LUC, and 50 ng CMV-hAR/W741L-AR/T877A-AR using Lipofectamine transfection reagent in optiMEM medium. Medium was changed 24 h after transfection to DME + 5% csFBS without phenol red and treated with a dose response of various drugs (1 pM to 10 ^M). SARDs and antagonists were treated in combination with 0.1 nM R1881. Luciferase assay was performed 24 h after treatment on a Biotek synergy 4 plate reader. Firefly luciferase values were normalized to renilla luciferase values. (Table 12) AR Degradation was performed using LNCaP, 22RV1, and AD1 cells as described herein above and in Example 13. Determination of metabolic stability (in vitro CLint) of test compounds:

[00803] Phase I metabolism

[00804] The assay was done in a final volume of 0.5 ml in duplicates (n=2). Test compound (1mM) was pre-incubated for 10 minutes at 37ºC in 100 mM Tris-HCl, pH 7.5 containing 0.5 mg/ml liver microsomal protein. After pre-incubation, reaction was started by addition of 1 mM NADPH (pre-incubated at 37ºC). Incubations were carried out in triplicate and at various time-points (0, 5, 10, 15, 30 and 60 minutes) 100 ml aliquots were removed and quenched with 100 ml of acetonitrile containing internal standard. Samples were vortex mixed and centrifuged at 4000 rpm for 10 minutes. The supernatants were transferred to 96 well plates and submitted for LC-MS/MS analysis. As control, sample incubations done in absence of NADPH were included. From %PCR (% Parent Compound Remaining), rate of compound disappearance is determined (slope) and in vitro CLint (ml/min/mg protein) was calculated.

[00805] Metabolic stability in Phase I & Phase II pathways

[00806] In this assay, test compound was incubated with liver microsomes and disappearance of drug was determined using discovery grade LC-MS/MS. To stimulate Phase II metabolic pathway (glucuronidation), UDPGA and alamethicin was included in the assay. [00807] LC-MS/MS analysis: [00808] The analysis of the compounds under investigation was performed using LC-MS/MS system consisting of Agilent 1100 HPLC with an MDS/Sciex 4000 Q-Trap™ mass spectrometer. The separation was achieved using a C18 analytical column (Alltima TM , 2.1 X 100 mm, 3 µm) protected by a C 18 guard cartridge system (SecurityGuard™ ULTRA Cartridges UHPLC for 4.6mm ID columns, Phenomenex). Mobile phase was consisting of channel A (95% acetonitrile + 5% water + 0.1% formic acid) and channel C (95% water + 5% acetonitrile + 0.1% formic acid) and was delivered at a flow rate of 0.4 mL/min. The volume ratio of acetonitrile and water was optimized for each of the analytes. Multiple reaction monitoring (MRM) scans were made with curtain gas, collision gas, nebulizer gas, and auxiliary gas optimized for each compound, and source temperature at 550°C. Molecular ions were formed using an ion spray voltage of -4200 V (negative mode). Declustering potential, entrance potential, collision energy, product ion mass, and cell exit potential were optimized for each compound. [00809] Table 12: AR Binding, Inhibition of wt and mutant AR Transactivation, AR degradation and in vitro metabolic stability of SARDs.

[00810] The relatively long half-lives (T 1/2 ) and low metabolic clearance (CL int ) values in vitro for compounds 200-202 of this invention suggest the possibility of oral bioavailability and stability in serum which would be favorable for systemic treatment of diseases of this invention such as prostate cancer, breast cancer, Kennedy’s disease, and various androgen-dependent diseases. Similarly, indazoles such as 96 also demonstrated enhanced stability, as discussed herein above.

AR Degradation Using Compounds of this Invention LNCaP Degradation Assay

Objective: To determine the effect of SARDs on AR expression in LNCaP cells.

Plasmid constructs and transient transfection.

[00813] Human AR cloned into CMV vector backbone was used for the transactivation study. HEK-293 cells were plated at 120,000 cells per well of a 24 well plate in DME + 5% csFBS. The cells were transfected using Lipofectamine (Invitrogen, Carlsbad, CA) with 0.25 µg GRE-LUC, 0.01 µg CMV-LUC (renilla luciferase) and 25 ng of the AR. The cells were treated 24 hrs after transfection as indicated in the figures and the luciferase assay performed 48 hrs after transfection. Data are represented as IC50 obtained from four parameter logistics curve.

Ligand binding assay.

[00814] hAR-LBD (633-919) was cloned into pGex4t.1. Large scale GST-tagged AR-LBD was prepared and purified using a GST column. Recombinant ARLBD was combined with [ 3 H]mibolerone (PerkinElmer, Waltham, MA) in buffer A (10 mM Tris, pH 7.4, 1.5 mM disodium EDTA, 0.25 M sucrose, 10 mM sodium molybdate, 1 mM PMSF) to determine the equilibrium dissociation constant (Kd) of [ 3 H]mibolerone. Protein was incubated with increasing concentrations of [ 3 H]mibolerone with and without a high concentration of unlabeled mibolerone at 4ºC for 18 h in order to determine total and non-specific binding. Non-specific binding was then subtracted from total binding to determine specific binding and non-linear regression for ligand binding curve with one site saturation to determine the Kd of mibolerone.

[00815] Increasing concentrations of SARDs or DHT (range: 10 -12 to 10 -4 M) were incubated with [ 3 H]mibolerone and AR LBD using the conditions described above. Following incubation, the ligand bound AR-LBD complex was isolated using BioGel HT hydroxyapatite, washed and counted in a scintillation counter after adding scintillation cocktail. Values are expressed as Ki.

LNCaP gene expression assay.

[00816] Method: LNCaP cells were plated at 15,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Forty-eight hours after plating, cells were treated with a dose response of SARDs. Twenty four hours after treatment, RNA was isolated using cells-to-ct reagent, cDNA synthesized, and expression of various genes was measured by realtime rtPCR (ABI 7900) using taqman primers and probes. Gene expression results were normalized to GAPDH.

LNCaP growth assay.

[00817] Method: LNCaP cells were plated at 10,000 cells/well of a 96 well plate in RPMI + 1% csFBS without phenol red. Cells were treated with a dose response of SARDs. Three days after treatment, cells were treated again. Six days after treatment, cells were fixed and cell viability was measured by SRB assay.

LNCaP or AD1 degradation.

[00818] Method: LNCaP or AD1 cells expressing full length AR were plated at 750,000- 1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed to RPMI + 1% csFBS without phenol red and maintained in this medium for 2 days. Medium was again changed to RPMI + 1% csFBS without phenol red and cells were treated with SARDs (1 nM to 10 µM) in combination with 0.1 nM R1881. After 24 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt- containing lysis buffer with three free-thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody from SantaCruz and actin antibody from Sigma.

22RV1 and D567es degradation.

[00819] Method: 22RV1 and D567es cells expressing AR splice variants were plated at 750,000-1,000,000 cells/well of a 6 well plate in growth medium (RPMI + 10% FBS). Twenty four hours after plating, medium was changed and treated. After 24-30 h of treatment, cells were washed with cold PBS and harvested. Protein was extracted using salt-containing lysis buffer with three free- thaw cycles. Protein concentration was estimated and five microgram of total protein was loaded on a SDS-PAGE, fractionated, and transferred to a PVDF membrane. The membrane was probed with AR N-20 antibody from SantaCruz and actin antibody from Sigma.

22RV1 growth and gene expression.

[00820] Methods: Cell growth was evaluated as described before by SRB assay. Cells were plated in 96 well plate in full serum and treated for 6 days with medium change after day 3. Gene expression studies were performed in 22RV1 cells plated in 96 well plate at 10,000 cells/well in RPMI + 10% FBS. Twenty four hours after plating, cells were treated for 3 days and gene expression studies were performed as described before.

Results:

[00821] Figure 26 presents AR degradation by 200 vs. ARN-509 in LNCaP cells. Western blot analysis by the method described above demonstrated the ability of 200 to degrade a mutant AR (i.e., T877A) at 100 nM and 10 µM in LNCaP cells whereas ARN-509 only degraded at 10 µM, suggesting that SARDs such as 200 will have clinical utility in prostate cancers including those whose growth is driven by antiandrogen resistance-conferring mutant AR’s (i.e., advanced prostate cancers and CRPC).

[00822] Figure 27 and Figure 28 present AR and AR-V7 degradation by 200 and 201 in 22RV-1 cells.200 was capable of degrading full length androgen receptor (AR-FL) and truncated AR (AR-V7) in 22RV-1 cells, suggesting that SARDs may be able to overcome AR-V7 dependent prostate cancers (i.e., CRPC). By comparison, 201 demonstrated low levels of degradation in 22RV- 1 cells.

[00823] These SARD activity demonstrations in Figures 26-28 as well as reported in the Tables suggest the compounds of this invention are able to degrade a variety of AR variants, and hence should provide the ability to inhibit the AR-axis activity whether it is androgen-dependent or androgen-independent. Degradation of the AR removes the possibility of promiscuous activation of mutant ARs, activation by intracellular processes such as signal transduction and kinase activation, etc.; and suggests that the SARDs should also degrade the polyQ polymorphism in hyperandrogenic dermatologic disorders (shortened polyQ) or Kennedy’s disease (extended polyQ), providing a rationale for treating either type of diseases by destroying the AR in the affected tissues (skin and neuromuscular system, respectively). EXAMPLE 15

Further studies with SARDs

PCa gene expression and cell growth:

[00824] PCa cells (LNCaP and 22RV1) will be plated at 10,000 cells per well of a 96 well plate in respective medium supplemented with 1% csFBS or in full serum. The cells will be maintained for 3 days and will be treated with SARDs or controls alone or in combination with 0.1 nM R1881 (1% csFBS). RNA will be isolated and cDNA prepared using cells-to-ct kits (Life Technologies). Expression of various androgen-regulated genes will be measured using TaqMan primer probe mix on an ABI 7900 realtime PCR machine. The expression of individual genes will be normalized to 18S rRNA levels.

[00825] PCa cells will be plated at 10,000 cells per well of a 96 well plate in respective medium supplemented with 1% csFBS or in full serum. The cells will be treated with SARDs alone or in combination with 0.1 nM R1881. The cell viability will be measured using Sulforhodamine blue reagent. As negative control, AR-negative PC3 cells will be treated similarly to ensure the absence of any non-specific growth inhibitory properties of SARDs. Preclinical Rodent Pharmacokinetic (PK) Studies:

[00826] The PK parameters of SARDs in various formulations will be determined in rats and mice as appropriate. Approximately 250 gram Sprague-Dawley rats will be randomized into groups of 5 and a catheter surgically implanted into the jugular vein. After a recovery period the rats will be administered test compound and 250 mL of venous blood will be serially sampled from the catheter at 0, 10, 20, 30, 60, 120, 240, 480, 720, 1440 and 2880 minutes post administration for an intravenous dose or 0, 20, 40, 60, 90, 120, 150, 180, 210, 240, 480, 720, 1440, and 2880 minutes post administration for a non-intravenous dose. For mice, approximately 20 gram C57BL/6 mice will be grouped into three per time point per route of administration. Following administration of an intravenous dose mice will be sacrificed and blood collected by cardiac puncture at 0, 10, 20, 30, 60, 120, 240, 480, 720, 1440 and 2880 minutes after intravenous dosing or 0, 30, 60, 90, 120, 150, 180, 210, 240, 480, 720, 1440, 2880 minutes after dosing for a non-intravenous dose. Samples will be collected in appropriate anti-coagulant containing tubes and plasma prepared for LC-MS-MS analyses. Relevant PK parameters will be estimated via non-compartmental analyses using Phoenix WinNonlin. PCa Xenograft studies: [00827] Nod Scid g (NSG)/nude mice (6-8 weeks in age) will be used in the xenograft experiments. Briefly, a mixture of 1:1 LNCaP or 22RV-1 cells in medium (10%FBS supplemented medium):matrigel mixture will be implanted subcutaneously in male NSG mice. Cell number to be implanted will depend on the cell type. Tumors will be implanted in male nude mice that have high circulating androgens or in castrated animals supplemented with DHT to streamline the hormone circulation and to reduce variability between animals. For CRPC model, animals will be castrated when VCaP tumors reach 100 mm 3 and the tumors will be allowed to re-grow as CRPC. Animals will be randomized into groups once the tumors reach 200 mm 3 and will be treated daily with vehicle or respective SARD. Tumor volume will be measured thrice weekly and the animals will be sacrificed at the end of the study. At sacrifice, tumors will be weighed and stored for further histological and molecular biological analysis. Tumor volume will be calculated using the formula length×width×width×0.5236. Cai et al. (Cancer Research, 71(20), 2011) have characterized VCaP cells as expressing high levels of androgen biosynthesis enzymes CYP17A1, AKR1C3, and HSD6B resulting in high intratumoral androgen levels. EXAMPLE 16

In Vivo Studies of SARDs (indoles and indolines)

[00828] Hershberger assay: Mice (6-7 weeks old) were treated with vehicle or indicated SARDs (100 mg/kg/day twice daily) for 14 days orally. Animals were sacrificed and seminal vesicles (S.V.) weights were recorded and represented.

[00829] Results: SARDs 11, 34, 36, 37, 38, 103, and 115 demonstrated varying levels of inhibition of seminal vesicles (S.V.) growth. 103 and 36 had the greatest effect on suppressing S.V. growth (Figures 30A and 30D), prostate (Figure 30C), and also had an effect of body weight (Figure 30B). This suggests that these SARDs, despite low levels in the serum, were able to exert antiandrogenic effects on androgen dependent organs, supporting their potential use as treatments for prostate cancer and other diseases as described herein.

[00830] SARDs were also investigated in xenograft studies. 103 demonstrated low levels of efficacy in patient derived (Figure 31) and mouse (Figure 32) xenografts despite very low levels in the plasma. Table 15: SARDs are detected in plasma and patient derived tumor.

[00831] However, unexpectedly 103 was found to accumulate in the tumor (Table 15), possibly explaining its activity in the xenografts.

SARDs selectively accumulate in tumor: NSG mice were implanted with patient-derived prostate cancer xenograft. Animals were treated for 14 days and tumor volumes were measured twice weekly. Animals were sacrificed, 103 extracted from serum and tumor and measured using a LC-MS/MS method.

[00832] 103 selectively accumulates in tumor with almost 10 times more tumor accumulation than in plasma. While 103 had weak activity in tumor xenografts, 36

demonstrated promising inhibition of tumor growth. Example 17

SARDs Inhibit Transcriptional Activation of F876L

[00833] To validate that SARDs of the invention can antagonize the R1881-driven transcriptional activation of mutant AR F876L, COS cells were transfected with F876L AR with a GRE-driven luciferase reporter construct, and a Renilla reporter construct as a control for transfection efficiency. Cells were treated 24 h after transfection with 0.1 nM R1881 (AR agonist) and a dose response of SARDs. Luciferase (and Renilla) assays were performed 48 h after transfection and reported as relative light unit (RLU). COS is not a prostate cancer cell line, so transfection with F876L does not confer enzalutamide resistance (Enz-R). Figure 50A (top middle panel) demonstrated potent (low nM) but not full efficacy antagonism by enzalutamide of R1881-driven F876L transactivation, whereas wt AR inhibition was less potent (low µM) and full efficacy. Importantly, at high concentrations (>1 µM), enzalutamide acts as an agonist of F876L transactivation (top right panel of Figure50A), which is not seen in wt AR. This is indicative that F876L acts like an agonist switch escape mutant of enzalutamide therapy. Given that SARDs of this invention were structurally novel high potency AR antagonists with a unique biological activity profile, representative compounds (i.e., 11 (5-F indole), 22 (4-F indole), 23 (6-F indole), 37 (5-F indole), 101 (4-F indoline), and 36 (4-F indole)) were tested for their ability to overcome the agonist switch behavior. Approximately equipotent nM range, full efficacy antagonism of R1881-driven transcriptional activation was observed in both F876L and wt. This suggested that SARDs of this invention would also exhibit activity in models of Enz-R (e.g., MR49F cells) and primary prostate cancer (PC) possessing wt AR. Example 18

SARD activity and cellular anti-proliferation in the MR49F model of of enzalutamide

resistant prostate cancer (Enz-R PC)

[00834] To ensure that SARD activity was also maintained in a Enz-R cell line, SARD assays were performed in MR49F LNCaP cells containing the F876L/T877A double mutant. As seen in Figure 50B, 36 (4-F indole) and 115 (5-F, 6-Ph indoline) degraded this mutant FL AR in MR49F cells in the low µM and high nM range, respectively, consistent with the relative activities seen in Tables 3 and 6. Densitometric evaluation of the immunoblots suggests that 115 demonstrated similar to improved potency of SARD activities in the Enz-R LNCaP (Figure 50A) when compared to the parental enzalutamide sensitive LNCaP shown supra (Figure 49A). This suggests that the optimized activity profile for 115 reported in Table 6 was conserved in this model of Enz-R. Enzalutamide was inactive in SARD activity assays in LNCaP (FL) and 22RV1 (SV) cells and was not tested in MR49F cells as it was not expected to be a SARD in this or any cellular context. The preservation of SARD activity for these representative compounds even in the Enz-R context suggested that SARDs of the invention may exhibit broad spectrum anti-proliferative and/or anti-tumor activities across many prostate cancers including enzalutamide-resistant prostate cancers.

[00835] Anti-proliferative assays in MR49F cells showed that 103 (4-F indoline), 36 (4-F indole), and 34 (5-F, 6-Ph indole) completely and dose-dependently inhibited cell growth with estimated IC50 values of less than 3 µM for 103 and 36, and less than 1 µM for 34 (Figure 51). For 36 at least, this correlates well with in vitro proliferative antagonism and SARD activity in MR49F cells (Figures 50A and 50B), suggesting that SARDs of this invention retained their unique biological profile in Enz-R PC. By comparison, enzalutamide demonstrated weak and incomplete efficacy as revealed by poor dose-dependence and only partial inhibition of growth. E.g., growth inhibitions at 3 µM, 10 µM and 30 µM were approximately 30%, 15% and 45%. This result demonstrated the enzalutamide resistant of these MR49F cells, and further affirmed our ability to overcome the Enz-R phenotype with representative examples of SARDs of this invention, supporting testing in MR49F xenografts. Example 19

In Vivo Antagonism

[00836] Hershberger assays. Hershberger assays were performed on several SARDs of this invention in intact mice and rats. Surprisingly, despite poor mouse liver microsome (MLM) stabilities, the tested SARDs (103, 104, 23, 34, 11, 36, 37, 38 and 115) caused atrophy of AR- dependent seminal vesicles tissue in intact mice (Figure 52A, left panels) whereas vehicle did not have any effect (0% change). Similar efficacy atrophy was also observed for 103 and 104 in rats (Figure 52A, right panel) and was demonstrated to be dose-dependent in prostate and seminal vesicles, with up to ~40% change in organ weights relative to castrated control (100%). This confirms that orally administered compounds are being absorbed and distributed to the site of action in these organs and suggests that the compound should also distribute to tumors in xenograft models to exert anti-tumor effects in sensitive models.

[00837] MR49F Xenografts in mice: MR49F xenografts were established by implanting the Enz-R LNCaP cells (from University of British Columbia) mixed with Matrigel (BD Biosciences, San Jose, CA) at 1:1 ratio and injecting subcutaneously in NOD SCID gamma (NSG) mice. Once tumor sizes reached 100-200 mm 3 , the mice were castrated and the tumors were allowed to regrow as CRPC. The animals were randomized once the tumors started to regrow and treated with vehicle (polyethylene glycol-300: DMSO 85:15 ratio) or 100 mg per kg of SARDs 34 or 36 for 14 d. In Figure 52B, 34 and 36 significantly reduced the tumor volume with a 40-60% tumor growth inhibition (TGI).

[00838] Further, the significant levels of TGI activity indicated that the oral bioavailability demonstrated in Hershberger assays translated to adequate levels of 34 and 36 in tumor to reveal to some extent the pharmacodynamic behavior of the SARDs of this invention. \The proof-of-concept that the SARDs of the invention can overcome Enz-R CRPC in vivo was established through the susceptibility of these Enz-R xenografts to 34 and 36. This promising result is surprising given the poor metabolic stability of these SARDs as a whole in the same species (mice) as seen in MLM (Tables 4 and 6; T1/2 for 34 and 36 were 9.13 min and 11.77 min). These experiments indicate that the SARDs of this invention with their unique biological profile could be used to overcome enzalutamide, and by extension apalutamide and abiraterone, resistances, in CRPC patients.

[00839] SARD compounds of the invention as described herein are potent AR antagonists and with a broad activity profile in models of prostate cancer, and in vivo AR antagonism when orally administered. For example, SARDs exhibited strong AR antagonistic activity in vitro in transcriptional activation and cellular proliferative assays including in models of enzalutamide sensitive and resistant PCs, and/or castration resistant PCs (CRPCs).

[00840] Additionally, SARDs of the invention showed selective AR [protein] degradation of full- length (FL AR; e.g., from LNCaP cells (T877A)) and splice variant (SV AR; e.g., from 22RV1 cells (AR-V7)) isoforms of AR, all at sub to low micromolar treatment levels, and in a variety of prostate cancer cell contexts including enzalutamide resistant PCs (e.g., MR49F). The ability to degrade SV AR in the study suggested the potential of SARDs of this invention to treat various currently untreatable advanced and refractory PCs, for example, those lacking the ligand binding domain (LBD) of AR such as AR-V7 and D567es AR truncations, which are not susceptible to androgen- deprivation therapy, abiraterone, or LBD-directed antiandrogens (e.g., enzalutamide, apalutamide, and bicalutamide), and are associated with short survival.

[00841] Further, in vivo investigation found thatthe SARDs of the invention overcome a variety of escape mutants including F876L and F876L/T877A (MR49F) that are known to emerge due to enzalutamide treatment. These mutations convert enzalutamide and apalutamide to agonists, conferring resistance to prostate cancer cells and tumors via an agonist switch mechanism as seen with other LBD-binding antiandrogens, e.g. W741L for bicalutamide and T877A for flutamide (N- (4-nitro-3-(trifluoromethyl)phenyl)isobutyramide). The intractability of truncation mutants and the frequency of the agonist switch mutations suggest that novel ways, potentially LBD-independent ways, of targeting the AR are needed. Moreover, these orally bioavailable SARDs are dual acting agents, i.e., potent inhibitors and degraders of AR, providing a higher evolutionary barrier to the development of resistance to SARDs. N-terminally directed SARDs such as the SARDs of this invention may provide a next generation of AR antagonists to treat a variety of refractory and/or advanced prostate cancers, including enzalutamide-resistant, castration resistant, and/or AR-V7 dependent PCs which are not amendable with current hormone therapies. As such, SARDs may delay the need to rely solely on chemotherapy.

[00842] SARDs of the invention have a unique biological activity profile optimized to address Enz-R CPRC, including:

1) Generally bind to LBD of AR;

2) Inhibit transcriptional activation of wildtype AR, escape mutant ARs (T877A in Tables 3 and 6, F876L in Figure 50A, and Q711A

3) Exert high efficacy and potency SARD activity against FL and SV AR whether wildtype or harboring point-mutations (LNCaP in Tables 3 and 6) or truncations (22RV1 in Tables 3 and 6), including an Enz-R cellular contexts (e.g., MR49F in Figure 50B);

4) Exert AR antagonism in vivo when administered orally in intact animals (Figure 52A); 5) Exert PC anti-proliferative activity in vitro (Figure 51) and in vivo (see LNCaP, 22RV1) including in Enz-R CRPC (Figure 52B); and

6) Bind to a secondary binding site in AF-1 believed to mediate SARD activity as demonstrated for 11 by steady fluorescence and NMR studies, as demonstrated herein.

SBMA Method

[00843] Transgenic mice that express AR121Q (121 polyglutamine repeats instead of the usual 15-24 repeats) will be treated with vehicle or SARD orally. One group of mice will be castrated to serve as positive control as circulating androgens will worsen the SBMA (X-linked spinal-bulbar muscular atrophy) condition. Body weight, composition, and grip strength will be measured before the initiation of the experiment. Animals will be treated and weekly measurements will be performed. Animals will be treated and monitored until they die. AR121Q mice live only up to 60-80 days and hence evaluating the survival in the presence of SARD treatment is possible. ALS Method

[00844] All experiments will be performed in male hSOD1-G93A mice (Jax labs; PMID: 26786249) as a model of anterior lateral sclerosis (ALS). Mice will be randomized and treated with either vehicle or SARD of this invention dissolved in DMSO + PEG-300 (15%+85%). Simultaneously, a group of mice will be castrated and used as positive control as castration has been shown to extend survival and disease duration in this model (PMID: 24630363). Mice will be treated orally every day until they reach morbidity. Weekly body weight and composition by magnetic resonance imaging (MRI) will be recorded. The mice performance will be measured each week by using a grip strength meter (Columbus instruments) or rotarod. Inability for the mice to move will be considered as a terminal disease state and the mice will be sacrificed. Example 21

(S)-N-(6-Cyano-5-(trifluoromethyl)pyridin-3-yl)-3-(3,5-diflu oro-1H-indazol-1-yl)-2-hydroxy- 2-methylpropanamide (99)

[00883] To a dry, nitrogen-purged 50 mL round-bottom flask equipped with a dropping funnel under argon atmosphere, NaH of 60% dispersion in mineral oil (15 mg, 0.36 mmol) was added in 5 mL of anhydrous THF solvent in the flask at ice-water bath, and 3,5-difluoro-1H-indazole (27 mg, 0.18 mmol) was stirred 30 min at the ice-water bath. Into the flask, (R)-3-bromo-N-(6-cyano-5- (trifluoromethyl)pyridin-3-yl)-2-hydroxy-2-methylpropanamide (8a, 62 mg, 0.18 mmol) in 5 mL of anhydrous THF was added through dropping funnel under argon atmosphere at the ice-water bath and stirred overnight at room temperature. After adding 1 mL of H2O, the reaction mixture was condensed under reduced pressure, and then dispersed into 50 mL of EtOAc, washed with 50 mL (x 2) water, evaporated, dried over anhydrous MgSO 4, and evaporated to dryness. The mixture was purified with flash column chromatography as an eluent EtOAc/ hexane = 2/3 to produce the designed compound (99) as white solid.
