STATEMENT REGARDING FEDERALLY SUPPORTED RESEARCH OR

DEVELOPMENT

[003] The invention described herein was made with government support under Grant No. CA148706, awarded by The National Institutes of Health. The government has certain rights in the invention.

BACKGROUND OF THE INVENTION

[004] Cancer is the second most common cause of death in the United States, exceeded only by heart disease. In the United States, cancer accounts for 1 of every 4 deaths. The 5-year relative survival rate for all cancer patients diagnosed in 1996-2003 is 66%, up from 50% in 1975-1977 {Cancer Facts & Figures American Cancer Society: Atlanta, GA (2008)). This improvement in survival reflects progress in diagnosing at an earlier stage and improvements in treatment. Discovering highly effective anticancer agents with low toxicity is a primary goal of cancer research.

[005] Microtubules are cytoskeletal filaments consisting of a and b-tubulin heterodimers and are involved in a wide range of cellular functions, including shape maintenance, vesicle transport, cell motility, and division. Tubulin is the major structural component of the microtubules and a P-579080-PC well verified target for a variety of highly successful anti-cancer drugs. Compounds that are able to interfere with microtubule-tubulin equilibrium in cells are effective in the treatment of cancers. Anticancer drugs like taxol and vinblastine that are able to interfere with microtubule-tubulin equilibrium in cells are extensively used in cancer chemotherapy. There are three major classes of antimitotic agents. Microtubule- stabilizing agents, which bind to fully formed microtubules and prevent the depolymerization of tubulin subunits, are represented by taxanes and epothilones. The other two classes of agents are microtubule-destabilizing agents, which bind to tubulin dimers and inhibit their polymerization into microtubules. Vina alkaloids such as vinblastine bind to the vinca site and represent one of these classes. Colchicine and colchicine- site binders interact at a distinct site on tubulin and define the third class of antimitotic agents.

[006] Both the taxanes and vinca alkaloids are widely used to treat human cancers, while no colchicine- site binders are currently approved for cancer chemotherapy yet. However, colchicine binding agents like combretastatin A-4 (CA-4) and ABT-751, are now under clinical investigation as potential new chemotherapeutic agents (Luo et al., ABT-751, "A novel tubulin binding agent, decreases tumor perfusion and disrupts tumor vasculature," Anticancer Drugs 2009, 20(6), 483-92; Mauer et al., "A phase II study of ABT-751 in patients with advanced non small cell lung cancer," J. Thorac. Oncol., 2008, 3(6), 631-6; Rustin et al., "A Phase lb trial of CA4P (combretastatin A-4 phosphate), carboplatin, and paclitaxel in patients with advanced cancer," Br. J. Cancer, 2010, 102(9), 1355-60).

[007] Unfortunately, microtubule-interacting anticancer drugs in clinical use share two major problems, drug resistance development and neurotoxicity. A common mechanism of drug resistance is because of multidrug resistance proteins (MDRs), namely ATP binding cassette (ABC) transporter protein-mediated drug efflux, limits the efficacy of these drugs (Green et al., "Beta-Tubulin mutations in ovarian cancer using single strand conformation analysis-risk of false positive results from paraffin embedded tissues," Cancer Letters, 2006, 236(1), 148-54; Wangei al., "Paclitaxel resistance in cells with reduced beta -tubulin," Biochimica et Biophysica Acta, Molecular Cell Research, 2005, 1744(2), 245-255; Leslie et al., "Multidrug resistance proteins: role of P-glycoprotein, MRP1, MRP2, and BCRP (ABCG2) in tissue defense," Toxicology and Applied Pharmacology, 2005, 204(3), 216-237). P-579080-PC

[008] P- glycoproteins (P-gp protein is encoded by the MDR1 gene) are important members of the ABC superfamily. P-gp prevents the intracellular accumulation of many cancer drugs by actively effluxing drug out of cancer cells, as well as contributing to normal hepatic, renal, or intestinal clearance pathways. Attempts to co-administer P-gp modulators or inhibitors to increase cellular availability by blocking the actions of P-gp have met with limited success (Gottesman et al., "The multidrug transporter, a double-edged sword," J. Biol. Chem., 1988, 263(25), 12163-6; Fisher et al., "Clinical studies with modulators of multidrug resistance," Hematology/Oncology Clinics of North America, 1995, 9(2), 363-82).

[009] The other major problem with taxanes, as with many biologically active natural products, is its lipophilicity and lack of solubility in aqueous systems. This leads to the use of emulsifiers like Cremophor EL and Tween 80 in clinical preparations. A number of biologic effects related to these drug formulation vehicles have been described, including acute hypersensitivity reactions and peripheral neuropathies (Hennenfent, et al., "Novel formulations of taxanes: a review. Old wine in a new bottle?" Ann. Oncol., 2006, 17(5), 735-49; ten Tije, et al., "Pharmacological effects of formulation vehicles : implications for cancer chemotherapy," Clin. Pharmacokinet., 2003, 42(7), 665-85).

[0010] Compared to compounds binding the paclitaxel- or vinca alkaloid binding site, colchicine binding agents usually exhibit relatively simple structures. Thus, providing a better opportunity for oral bioavailability via structural optimization to improve solubility and pharmacokinetic (PK) parameters. In addition, many of these drugs appear to circumvent P-gp-mediated drug resistance. Therefore, these novel colchicine binding site targeted compounds hold great promise as therapeutic agents, particularly since they have improved aqueous solubility and overcome P- gp mediated drug resistance.

[0011] Triple negative breast cancer is found in 15% of all cases of breast cancer in the United States. Triple negative breast cancer is defined as tumor that lack expression of estrogen receptor (ER), progesterone receptor (PR), and human epithermal growth factor receptor (HER-2). Triple negative breast cancer is characterized by aggressive clinical behavior and poor prognosis due to rapid resistance to many chemotherapeutic drugs and lack of suitable targets. Currently, there are no approved targeting therapies available. Classic microtubule-targeted drugs (MTDs), such as paclitaxel and its semisynthetic derivatives, have achieved considerable success in the clinical P-579080-PC management of breast cancer neoplasms. Anthracyclines and taxanes based chemotherapy is a standard care for triple negative breast cancer. However, eventually most triple negative breast cancer patients will develop drug resistance, tumor relapse, and/or metastasis after a transient response to initial rounds of therapies. There is an urgent need to develop innovative and more effective therapeutic approaches that achieve a more durable response to triple negative breast cancer treatment.

[0012] Metastatic ovarian cancer is the most lethal gynecological malignancy in women and chemotherapy is one of the standard treatment options. Even though there are several FDA approved anti-tubulin agents, mainly taxanes, that are included in the effective management of ovarian cancer, drug resistance to taxanes often develops with resulting disease progression.

[0013] With the rising incidence of triple negative breast cancer and ovarian cancer and the high resistance to current therapeutic agents, developing more effective drugs for treating such cancers that can effectively circumvent MDR will provide significant benefits to cancer patients.

Figure 16A illustrates the MDA-MD-231 cell viability after treatment with colchicine, paclitaxel, and compound l7ya with IC50 (nM) of 17.46, 3.05, and 8.23, respectively, and SEM of 3.40, 0.42, and 1.34, respectively. Figure 16B illustrates the MDA-MD- 468 cell viability after treatment with colchicine, paclitaxel, and compound l7ya with IC50 (nM) of 9.80, 4.61, and 9.59, respectively, and SEM of 1.45, 0.63, and 1.78, respectively.

[0038] Figures 17A-B illustrate the cell migration inhibition of compound l7ya and colchicine. Figure 17A illustrates the effect of colchicine or compound l7ya on cell migration as compared to P-579080-PC the control.

[0040] Figure 19 illustrates the effect of compound l7ya (VERU-l l l) on apoptosis induction in TNBC cells where MDA-MB-231 cells were treated with 100 nM compound l7ya in a time- dependent manner and the compound induced the cells to apoptosis as compared to the control at 24h, 48h, and 72h with various times and concentrations.

[0041] Figure 20 illustrates the anti-cancer activity of compound l7ya (VERU-l 11) in orthotopic TNBC mouse model to determine if the potent effect of compound l7ya could be observed in vivo as determined over time, including after 33 days of treatment, where compound l7ya inhibited TNBC tumor growth in a dose dependent manner without interfering the body weight of mice.

[0042] Figure 21 illustrates the comparison of the efficacy of compound l7ya (VERU-l 11) with paclitaxel in a model since paclitaxel is one of the standard cares for TNBC treatment in clinic, were compound l7ya and paclitaxel significantly regressed the tumor size and tumor weight.

[0043] Figure 22 illustrates H & E staining of tumors in a comparison study of compound l7ya (VERU-l 11) and paclitaxel in induced TNBC tumor necrosis in the lung tissue where the vehicle group were full of metastasis (indicated by yellow arrow), while the lungs in compound l7ya and paclitaxel group had little, suggesting that compound l7ya significantly reduced metastasis of TNBC.

[0044] Figure 23 illustrates IHC staining of tumors in a comparison study of compound l7ya (VERU-l 11) and paclitaxel in induced TNBC tumor necrosis in the lung tissue where the vehicle group were full of metastasis (indicated by yellow arrow), while the lungs in compound l7ya and paclitaxel group had little, suggesting that compound l7ya significantly reduced metastasis of TNBC.

[0045] Figure 24 illustrates a brief compound summary showing that compound VERU-l 11 (compound l7ya) is a novel, oral, next generation tubulin inhibitor targeting a and b subunits of microtubules with low nanomolar inhibition of tubulin polymerization, high oral bioavailability, P-579080-PC high brain penetration, and having efficacy against prostate, breast, and other cancers in vivo and in vitro.

[0046] Figure 25 illustrates that VERU-l l l (compound l7ya) is built on a proven mechanism- inhibiting microtubule assembly and comparing the microtubules disrupted from spindle shape (control) versus globular shape (compound l7ya).

[0047] Figures 26A-B illustrate molecular modeling of VERU-l l l (compound l7ya) with tubulin complex (compound l7ya = 6a). Figure 26A illustrates the molecular modeling of compound l7ya with the colchine binding site, where the compound is closer in its binding pose to TN-16 than it is to colchine itself. Figure 26B illustrates that compound l7ya is more linear and penetrates deeper in the binding pocket of the b-tubulin monomer than TN-16 and has hydrogen bonding which results in differential and stronger binding to a and b tubulin.

[0048] Figure 27 illustrates drug-like attributes of VERU-l l l (compound l7ya) and VERU-112 (compound 55).

[0049] Figure 28 illustrates pharmacokinetic parameters of VERU-l l l (compound l7ya) and VERU-l 12 (compound 55) in mice, rats, and dogs.

[0050] Figure 29 illustrates a metabolism pathway for VERU-l l l (compound l7ya) in human and dogs, where the abundant metabolite M+34 was only found in dog liver microsomes resulting in high clearance in dog in vivo.

[0051] Figure 30 illustrates brain penetration of VERU-l l l (compound l7ya) and VERU-l 12 (compound 55). VERU-l 12 (compound 55) demonstrated high brain penetration. Brain/plasma concentration ratio was about 20% 4h after oral treatment. Brain/plasma concentration ratios remained relatively constant over time for VERU-l 11 (compound l7ya) and VERU-l 12 (compound 55) suggesting that brain concentrations were in the same pharmacokinetic compartment as plasma and will not accumulate in the brain; perhaps, reducing the possibility for neurotoxicity.

[0052] Figure 31 illustrates compound’s activity on p-glycoprotein ATPase (Pgp ATPase). VERU-l 11 (compound l7ya) was not a substrate for p-glycoprotein, where p < 0.05.

[0053] Figure 32 illustrates a summary of VERU-l l l (compound l7ya) in vitro and in vivo cytotoxic activities, demonstrating similar or greater potency as paclitaxel and docetaxel in parental lines; while paclitaxel and docetaxel lose activity in taxane-resistant cell lines, VERU-l l l P-579080-PC

(compound l7ya) has potent antiproliferative activity; and the compound is cytotoxic against multiple cancer types: prostate, taxane resistant prostate cancer, breast, triple negative breast, lung, melanoma, glioma, colon, uterine, ovarian, and pancreatic cancers.

[0054] Figure 33 illustrates VERU-l l l (compound l7ya) In vitro cytotoxicity after 96 hours (IC50 values - nM). VERU-l l l (compound l7ya) has similar potency as paclitaxel and docetaxel in the parental PC-3 cell line. VERU-l l l (compound l7ya) retains its potency in the paclitaxel resistant PC-3 cells whereas paclitaxel and docetaxel lose potency.

[0055] Figures 34A-D illustrate VERU-l l l (compound l7ya) (P) and VERU-112 (IAT) inhibited paclitaxel resistant prostate cancer xenograft growth. Figure 34A illustrates the resistance against PC-3, where treatment was initiated when tumors reached 150-300 mm ³ . Figure 34B illustrates the resistance against TxR (PC-3/TxR is taxane resistant), where treatment was initiated when tumors reached 150-300 mm ³ . Figure 34C illustrates the resistance against TxR (PC-3/TxR is taxane resistant), where treatment was initiated when tumors reached 150-300 mm ³ . Figure 34D illustrates the resistance against TxR (PC-3/TxR is taxane resistant), where treatment was initiated when tumors reached 150-300 mm ³ .

[0056] Figure 35 illustrates anti-tumor activity of VERU-l l l (compound l7ya) and VERU-112 versus docetaxel in vivo. In contrast to the lack of efficacy of Docetaxel in PC-3/TxR tumors, VERU-l l l (compound l7ya) was dosed orally and had > 100% TGI without an effect on body weight.

[0057] Figure 36 illustrates VERU-l 11 (compound l7ya) tested in additional xenograft models.

[0058] Figure 37 illustrates anti-cancer activity of VERU-l l l (compound l7ya) in triple negative breast cancer (TNBC) in vitro , where in MDA-MB-231 colchine had IC50 of 17.46 (SE 0.05); paclitaxel ha IC50 of 3.05 (SE 0.04); and VERU-l l l (compound l7ya) had IC50 of 8.23 (SE 0.05). In MDA-MB-468 colchine had IC50 of 9.80 (SE 0.02); paclitaxel ha IC50 of 4.61 (SE 0.03); and VERU-l 11 (compound l7ya) had IC50 of 22.96 (SE 0.02).

[0059] Figure 38 illustrates anti-tumor activity of VERU-l 11 (compound l7ya) in TNBC in vivo , where VERU-l l l (compound l7ya) inhibits TNBC tumor growth in a dose dependent manner without interfering the body weight of mice. P-579080-PC

[0060] Figure 39 illustrates that VERU-l l l (compound l7ya) inhibited triple negative breast cancer xenographs in mice.

[0061] Figure 40 illustrates that VERU-l l l (compound l7ya) inhibited triple negative breast cancer metastases in mice.

When the dosage unit form is a capsule, it can contain, in addition to materials of the above type, a liquid carrier such as a fatty oil.

[00233] Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets can be coated with shellac, sugar, or both. A symp can contain, in addition to active ingredient, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye, and flavoring such as cherry or orange flavor.

[00234] For oral therapeutic administration, the active compounds can be incorporated with excipients and used in the form of tablets, capsules, elixirs, suspensions, symps, and the like. Such compositions and preparations should contain at least 0.1% of active compound. The percentage of the compound in these compositions can, of course, be varied and can conveniently be between about 2% to about 60% of the weight of the unit. The amount of active compound in such therapeutically useful compositions is such that a suitable dosage will be obtained. Preferred compositions according to the present invention are prepared so that an oral dosage unit contains between about 1 mg and 800 mg of active compound.

[00235] The active compounds or formulations thereof may be orally administered, for example, with an inert diluent, or with an assimilable edible carrier, or they can be enclosed in hard or soft shell capsules, or they can be compressed into tablets, or they can be incorporated directly with the food of the diet.

[00236] The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form should be sterile and should be fluid to the extent that easy syringability exists. It should be stable under the conditions of manufacture and storage and should be preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.

[00237] The compounds or pharmaceutical compositions of the present invention may also be administered in injectable dosages by solution or suspension of these materials in a physiologically acceptable diluent with a pharmaceutical adjuvant, carrier or excipient. Such adjuvants, carriers and/or excipients include, but are not limited to, sterile liquids, such as water and oils, with or without the addition of a surfactant and other pharmaceutically and physiologically acceptable components. Illustrative oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, or mineral oil. In general, water, saline, aqueous dextrose and related sugar solution, and glycols, such as propylene glycol or polyethylene glycol, are preferred liquid carriers, particularly for injectable solutions.

[00238] The active compounds or formulations thereof may also be administered parenterally. Solutions or suspensions of these active compounds can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof in oils. Illustrative oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, or mineral oil. In general, water, saline, aqueous dextrose and related sugar solution, and glycols such as, propylene glycol or polyethylene glycol, are preferred liquid carriers, particularly for injectable solutions. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

[00239] For use as aerosols, the compounds or formulations thereof in solution or suspension may be packaged in a pressurized aerosol container together with suitable propellants, for example, hydrocarbon propellants like propane, butane, or isobutane with conventional adjuvants. The materials of the present invention also may be administered in a non-pressurized form such as in a nebulizer or atomizer.

[00240] The compounds used in the methods of the invention are administered in combination with an anti-cancer agent. In one embodiment, the anti-cancer agent is a monoclonal antibody. In some embodiments, the monoclonal antibodies are used for diagnosis, monitoring, or treatment of cancer. In one embodiment, monoclonal antibodies react against specific antigens on cancer cells. In one embodiment, the monoclonal antibody acts as a cancer cell receptor antagonist. In one embodiment, monoclonal antibodies enhance the patient's immune response. In one embodiment, monoclonal antibodies act against cell growth factors, thus blocking cancer cell growth. In one embodiment, anti-cancer monoclonal antibodies are conjugated or linked to anti-cancer drugs, radioisotopes, other biologic response modifiers, other toxins, or a combination thereof. In one embodiment, anti-cancer monoclonal antibodies are conjugated or linked to a compound as described hereinabove.

[00241] Yet another aspect of the present invention relates to a method of treating triple negative breast cancer and/or ovarian cancer that includes selecting a subject in need of treatment the cancer and administering to the subject a pharmaceutical composition comprising at least one compound and a pharmaceutically acceptable carrier under conditions effective to treat the cancer.

[00242] When administering the compounds, they can be administered systemically or, alternatively, they can be administered directly to a specific site where cancer cells or precancerous cells are present. Thus, administering can be accomplished in any manner effective for delivering the compounds or the pharmaceutical compositions to the cancer cells or precancerous cells. Exemplary modes of administration include, without limitation, administering the compounds or compositions orally, topically, transdermally, parenterally, subcutaneously, intravenously, intramuscularly, intraperitoneally, by intranasal instillation, by intracavitary or intravesical instillation, intraocularly, intraarterially, intralesionally, or by application to mucous membranes, such as, that of the nose, throat, and bronchial tubes.

Biological Activity

[00243] The invention encompasses compounds and compositions for use in treating triple negative breast cancer and/or ovarian cancer. At least one compound or a composition comprising the same will have utility in inhibiting, suppressing, enhancing or stimulating a desired response in a subject, as will be understood by one skilled in the art. The compositions may further comprise additional active ingredients, whose activity is useful for the particular application for which the compound of this invention is being administered. [00244] Drug resistance is the major cause of cancer chemotherapy failure. One major contributor to multidrug resistance is overexpression of P-glycoprotein (P-gp). This protein is a clinically important transporter protein belonging to the ATP-binding cassette family of cell membrane transporters. It can pump substrates including anticancer drugs out of tumor cells through an ATP-dependent mechanism. The TNBC may be taxane-resistant TNBC, taxane- sensitive TNBC, and/or metastasis.

[00245] The method of treating TNBC was illustrated by the in vitro studies of compound l7ya determining the anticancer activity of the compound. Compound l7ya anti-TNBC activity was compared to colchicine and paclitaxel against cell lines MDA-MB-231 and MDA-MB-468. In tests with MDA-MB-231, the IC ₅ o(nM) was determined to be 17.46, 3.05, and 8.23 for colchicine, paclitaxel, and compound l7ya, respectively, and the SE was 0.05, 0.04, and 0.05, respectively. In tests with MDA-MB-468, the IC ₅ o(nM) was determined to be 9.80, 4.61, and 22.96 for colchicine, paclitaxel, and compound l7ya, respectively, and the SE was 0.02, 0.03, and 0.02, respectively. Figure 1 graphically illustrates the results of the anti-cancer activity of compound l7ya in vitro as compared to colchicine and paclitaxel for cell lines MDA-MB-231 and MDA-MB-468. Figure 2 illustrates the anti-migration of compound l7ya (16 nM) on TNBC cells as compared to colchicine (16 nM) and a control in cell lines MDA-MB-231 and MDA-MB- 468. The anti-invasion properties of compound l7ya (40 nM) was also determined in TNBC cell lines MDA-MB-231 and MDA-MB-468 as compared to a control, colchicine (32 nM) and paclitaxel (32 nM).

[00246] The cell apoptosis induction of compound l7ya on TNBC cells was also determined as compared against a control were 100 nM compound l7ya was studied at 24 hours, 48 hours, and 72 hours. See Figure 7 for illustration. Compound l7ya induced TNBC cell apoptosis in a dose and time-dependent manner as compared to a control where compound l7ya was studied at 50 nm, 100 nM, 150 nM, and 200 nM for 48 hours and compared to colchicine (200 nM, 48 hours) and paclitaxel (200 nM, 48 hours). The results are illustrated in Figure 8. The anti-cancer active of compound l7ya was studied in vivo at 5 mg/kg and 10 mg/kg and compared to a control and it was determined that compound l7ya inhibited TNBC tumor growth in a dose dependent manner without interfering with body weight. Figure 9 illustrates the percent tumor growth and body weight (g) comparison of compound l7ya at 5 mg/kg and 10 mg/kg to a control. Figure 10 illustrates the size comparison of tumors as compound l7ya inhibited TNBC tumor growth in a dose dependent manner.

[00247] The anti-cancer activity of compound l7ya was compared against paclitaxel. It was determined that compound l7ya inhibited TNBC tumor growth significantly over the control and similarly to paclitaxel treatment. Figure 11 illustrates the graphical comparison between vehicle, compound l7ya (12.5 g/kg), and paclitaxel (12.5 g/kg) effect on tumor weight (g) and final tumor volume (mm ³ ).

[00248] The anti-metastatic activity of compound l7ya in vivo was also studied. The activity of compound l7ya (10 mg/kg) was compared to a control and paclitaxel (10 mg/kg) in H 7 E sections from lungs. Figure 12 illustrates the results of this study, where compound l7ya resulted in very few metastases similarly to paclitaxel but in contrast to the control that had many metastases.

[00249] The efficacy of compound l7ya in vitro was determined using an orthotopic ovarian cancer mouse model. Two weeks after transplantation of SKOV3 cells into the left-side ovaries in NSG female mice, the mice were treated with vehicle or compound l7ya (10 mg/kg) orally for 4 weeks (5 treatments per week). To test the activity of compound l7ya in SKOV3 and OVCAR3 cells, cell survival ability was studied by performing colony formation assay. Cell migration and invasion were examined by using a modified transwell chamber. Precoated matrigel on the transwell inserts were used to test cells invasion ability.

[00250] Treatment with compound l7ya significantly inhibited SKOV3 ovarian tumor growth and metastasis to major organs (liver and spleen) in vivo, compared with the vehicle control (Table 1). Upon treatment with compound l7ya for 2 weeks at 10 nM or 30 nM concentration, cell growth in both SKOV3 and OVCAR3 was significantly reduced. Consistent with this finding, abilities of ovarian cancer cell migration and invasion were substantially inhibited with 20 nM of compound l7ya treatment in both SKOV3 and OVCAR3 cells. The results are summarized in the following Table 1:

*Note: for these dataset, the denominator is the number of tested mice, the numerator is the number of metastasized mice.

[00251] The test results demonstrated that orally available compound l7ya effectively inhibited tumor growth and metastasis in orthotopic ovarian cancer mouse model without acute toxicity and reduce ovarian cancer cells survival, migration and invasion abilities and concluding that compound l7ya is a tubulin inhibitor for the treatment of ovarian cancer.

[00252] In one embodiment, this invention provides methods for treating triple negative breast cancer and/or ovarian cancer comprising administering to the subject at least one compound described above and/or an isomer, metabolite, pharmaceutically acceptable salt, pharmaceutical product, tautomer, hydrate, /V-oxide, polymorph, or crystal of said compound, or any combination thereof in a therapeutically effective amount to treat the triple negative breast cancer.

[00254] A still further aspect of the present invention relates to a method of treating or preventing a cancerous condition that includes: providing at least one compound described above and then administering an effective amount of the compound to a patient in a manner effective to treat or prevent a cancerous condition. [00255] According to one embodiment, the patient to be treated is characterized by the presence of a precancerous condition, and the administering of the compound is effective to prevent development of the precancerous condition into the cancerous condition. This can occur by destroying the precancerous cell prior to or concurrent with its further development into a cancerous state.

[00256] According to another embodiment, the patient to be treated is characterized by the presence of a cancerous condition, and the administering of the compound is effective either to cause regression of the cancerous condition or to inhibit growth of the cancerous condition, i.e., stopping its growth altogether or reducing its rate of growth. This preferably occurs by destroying cancer cells, regardless of their location in the patient body. That is, whether the cancer cells are located at a primary tumor site or whether the cancer cells have metastasized and created secondary tumors within the patient body.

[00257] As used herein, subject or patient refers to any mammalian patient, including without limitation, humans and other primates, dogs, cats, horses, cows, sheep, pigs, rats, mice, and other rodents. In one embodiment, the subject is male. In another embodiment, the subject is female. In some embodiments, while the methods as described herein may be useful for treating either males or females.

[00258] When administering the compounds, they can be administered systemically or, alternatively, they can be administered directly to a specific site where cancer cells or precancerous cells are present. Thus, administering can be accomplished in any manner effective for delivering the compounds or the pharmaceutical compositions to the cancer cells or precancerous cells. Exemplary modes of administration include, without limitation, administering the compounds or compositions orally, topically, transdermally, parenterally, subcutaneously, intravenously, intramuscularly, intraperitoneally, by intranasal instillation, by intracavitary or intravesical instillation, intraocularly, intraarterially, intralesionally, or by application to mucous membranes, such as, that of the nose, throat, and bronchial tubes.

[00259] The method encompasses administering at least one compound in combination with an anti-cancer agent by administering the compounds as herein described, alone or in combination with other agents. [00260] When the compounds or pharmaceutical compositions of the present invention are administered to treat, suppress, reduce the severity, reduce the risk, or inhibit a cancerous condition, the pharmaceutical composition can also contain, or can be administered in conjunction with, other therapeutic agents or treatment regimen presently known or hereafter developed for the treatment of various types of cancer. Examples of other therapeutic agents or treatment regimen include, without limitation, radiation therapy, immunotherapy, chemotherapy, surgical intervention, and combinations thereof.

[00261] The following examples are presented to more fully illustrate the preferred embodiments of the invention. They should in no way, however, be construed as limiting the broad scope of the invention.

EXAMPLE 1

OVARIAN CANCER TUMOR GROWTH SUPPRESSION

[00265] Cell clonogenic survival assay. 350 SKOV3 or OVCAR3 cells were seeded on 6- well plates and cultured for 3 days with DMEM containing 10% FBS ( i.e ., growth media). On the third day of culture, the media was replaced with fresh growth media containing varying concentrations of compound l7ya ranging from 0, 1.25, 2.5,5,10 and 30 nM. The media was replaced every 3 days with fresh growth media containing compound l7ya until the l3th day of culture. Cells were then fixed with 70% ethanol and stained with crystal violet. Colonies from triplicate wells were counted for statistical analysis.

[00266] Cell migration assay. The cell migration assay was performed using a modified transwell chamber (BD FALCON, San Jose, CA). The chambers were inserted into 24-well cell culture plates. 3 x 104 SKOV3 or OVCAR3 cells with compound l7ya (20nM) and vehicle treatment in 300 pl serum-free DMEM were added to the upper chamber. DMEM containing 10% FBS (serving as the chemoattractant) was added into the lower chamber of each well and incubated for 8 h. The medium and nonmigrated cells in the upper chamber were removed, while the migrated cells on the lower side of the membranes were fixed with methanol and stained with crystal violet. Pictures were taken at 10X magnification, and cells from at least three different fields were counted.

[00267] Cell invasion assay. SKOV3 or OVCAR3 (5 x 10 ⁵ ) cells with compound l7ya (20nM) and vehicle treatment were seeded in 300 mΐ serum-free DMEM onto inserts precoated with Matrigel (BD BIOCOAT using 24-well Tumor Invasion System (BD BioSciences, San Jose, CA). DMEM containing 10% FBS was added to the bottom chamber of the invasion system as the chemoattractant and incubated for 24 h. The medium and nonmigrated cells in the upper chamber were removed, while the migrated cells on the lower side of the membranes were fixed with methanol and stained for 5 min with hematoxylin and eosin. Pictures were taken at 10X magnification. Invaded cells were counted in at least three different fields.

[00268] Orthotopic ovarian cancer mouse model. 5 x 105 SKOV3 cells labeled with a lentiviral vector expressing luciferase (pLenti-UBC-Luc2-T2A-mKate) were intrabursally injected into 10 two-month old NOD.Cg-Prkdcscid Il2rgtmlWjl/SzJ severely immunocompromised female mice (NSG). Two weeks after transplantation of SKOV3 cells into the left- side ovaries in NSG female mice, the mice were treated with vehicle or compound l7ya (10 mg/kg) orally for 4 weeks (5 treatments per week). Five mice were used for each group. Tumor initiation and metastasis were monitored once a week using a Xenogen imaging system. All mice were sacrificed at two months; the ovaries and metastasized organs were harvested and imaged using Xenogen imaging system; the tumors were weighed and tissues were processed for H&E staining.

[00269] The treatment with compound l7ya inhibited ovarian cancer cell survival. To test the effect of compound l7ya on ovarian cancer cells, cell survival was examined by assaying cell colony formation, as described above. 350 SKOV3 and OVCAR3 ovarian cells were cultured in 6-well plates and treated with compound l7ya at six doses of: 0, 1.25, 2.5, 5, 10 and 30 nM. On the l3th day, the colonies were stained with crystal violet. Compound l7ya significantly inhibited cell survival in both SKOV3 and OVCAR3 cells as illustrated in Figure 13 (**p<0.0l, ***p<0.00l).

[00270] Treatment with compound l7ya inhibited ovarian cancer cells migration and invasion. Using transwell plates, cell migration was tested against compound l7ya and vehicle treatment cells. It was found that cell migration was significantly reduced in both SKOV3 and OVCAR3 cells with compound l7ya as illustrated in Figure 14A. Cell invasion was assessed using Matrigel-coated transwells. Treatment with compound l7ya significantly reduced cells compared to the vehicle cells in both SKOV3 and OVCAR3, as illustrated in Figure 14B.

[00271] Compound l7ya inhibited ovarian tumor growth and metastasis in vivo. An orthotopic ovarian cancer mouse model was established. 5 xl05 Wildtype SKOV3-Luc2 cells were intrabursally injected into 2 month old NSG female mice and mice were treated five days a week for 4 weeks. Tumors were collected and imaged using Xenogen system. SKOV3 cells transduced with a lentiviral luciferase vector were injected into the left-side ovaries in two-month NSG mice, the mice were treated with vehicle or compound l7ya (lOmg/kg) for 4 weeks. Treatment with compound l7ya significantly inhibited SKOV3 ovarian tumor growth as illustrated in Figure 15B. Treating with compound l7ya inhibited metastasis to major organs (liver and spleen) in vivo as compared to the vehicle control as illustrated in Figure 15 A. The H.E staining on ovaries, tumors and livers showed that treatment with compound l7ya inhibited ovarian tumor growth and metastasis, as illustrated in Figure 15C. Tumors were not visible in ovaries, liver and spleen of mice treated with Compound l7ya.

EXAMPLE 2

[00272] Materials and Methods

[00273] Chemical compounds and cell lines. Colchicine was purchased from Sigma (St. Louse, MO). Paclitaxel was purchased from LC Laboratories (Woburn, MA). Compound l7ya was synthesized as described (Chen et al.,“Discovery of novel 2-aryl-4-benzoyl-imidazole (ABI- III) analogues targeting tubulin polymerization as antiproliferative agents.” J. Med. Chem ., 2012, 55. 7285-7289.), with purity ( 98%) and identity verified by HPLC, HR-MS (Waters, Milford, MA) and proton nuclear magnetic resonance (Bruker, Billerica, MA). Two human triple negative breast cancer (TNBC) cell lines were used in this study: MDA-MB-231 and MDA-MB-468 purchased from ATCC (Manassas, VA) and authenticated prior to use for this study. These cells were cultured in DMEM medium (Mediatech, Inc., Manassas, VA) supplemented with 10% fetal bovine serum (Atlanta Biologicals, Lawrenceville, GA) and 1% antibiotic-antimycotic Solution (Sigma-Aldrich, St. Louis, MO) at 37 °C in a humidified atmosphere containing 5% C0 ₂ .

[00274] Cell viability assay. The anti-proliferative effect of compound l7ya was investigated in human melanoma (A375 and M14), human HER2-positive breast (MDA-MB-453 and SKBR3) and TNBC (MDA-MB-231 and MDA-MB-468) cancer cell lines using routine MTS assay as described by Li et al.,“A Potent, Metabolically Stable Tubulin Inhibitor Targets Colchicine Binding Site and Overcomes Taxane Resistance,” Cancer Res., 2018, 78, 265-277. IC50 (50% of cell growth inhibition) values were calculated by GraphPad Prism 7 software using nonlinear regression.

[00275] Colony formation assay. MDA-MB-231 or MDA-MB-468 cells were seeded into l2-well plates with cell density of 200 cells/well and incubated for 24h. Cells were then treated with colchicine, paclitaxel and Compound l7ya at different concentrations. The medium of each group was renewed once a week. After culture for 7 days (MDA-MB-231) and 14 days (MDA- MB-468), the cells were washed with PBS, fixed with methanol and stained with 0.5% crystal violet. The morphology of colonies was captured under a microscope and colony area was quantified using ImageJ software (NIH, Bethesda, MD). The drug treatment was performed in triplicate. [00276] Caspase 3/7 activity assay. Apoptosis induced by compound l7ya was measured using Caspase Glo 3/7 assay system (Promega, Madison WI) according to the manufacturer’s instructions as described in Li et al.,“Design, Synthesis and Structure-Activity Relationship Studies of Novel Surviving Inhibitors with Potent Anti-Proliferative Properties,” PLoS One, 2015, 10, e0l29807. 5000 cells were seeded in each well of a 96-well plate and treated with compound l7ya 20 nM for 24h in triplicate. The caspase 3/7 activity was normalized by total protein content in each sample.

[00277] Cell migration and invasion assay. Chemotactic cell migration was carried out using Transwell 96-well plate contained a membrane insert (pore size 8pm) and a tray (BD Biosciences, CA), and the effect of compound l7ya on cell invasion was performed using matrigel invasion chamber (Coming, NY). In both assays, MDA-MB-231 and MDA-MB-468 cells in serum-free medium were starved for 24 h, followed by suspending the cells in serum-free medium containing 16 nM colchicine and compound l7ya and plating them in the top chamber of the membrane insert or matrigel-coated membrane in triplicate. Medium containing serum was added in the lower chamber as a chemoattractant. After 24 h incubation for MDA-MB-231 cells and 48 h incubation for MDA-MB-468 cells, the cells that did not migrate through the membrane or invade through the matrigel were removed by cotton swabs while the cells that had migrated or invaded to the bottom surface of the chamber were fixed in 4% buffered formalin phosphate solution, stained with 0.5% crystal violet solution and imaged by a microscope. The number of cells migrated or invaded were counted manually using ImageJ software.

[00278] Cell migration was also analyzed by the scratch assay. Briefly, MDA-MB-231 cells (10 ⁵ cells/well) and MDA-MB-468 (2 x 10 ⁵ cells/well) cells were seeded in l2-well plates and incubated overnight. The following day, a scratch was made in the cell monolayer by using a sterile 200-pl pipette tip. After washing away the floating cells, the cell culture medium was replaced by medium containing vehicle DMSO, colchicine, paclitaxel or compound l7ya at specific concentration (e.g., 16 nM). After 12 h, 24 h and 48 h, the wound width was determined and imaged with Evos Fl Imaging System (Life Technologies, Carlsbad, CA). The extent of wound closure was shown as the percentage of decrease of the original scratch width at each measured time point. Experiments were done in triplicate.

[00279] Immunofluorescence staining. 10 ⁵ MDA-MB-231 cells or 2 x 10 ⁵ MDA-MB-468 cells were seeded in 6-well plates on sterile coverslips for 24 h prior to treatment with 32 nM colchicine, paclitaxel and compound l7ya for 18 h. For tubulin visualization, cells were washed three times with PBS, fixed with 4% paraformaldehyde for 15 min and permeabilized with 0.2% Triton X-100 in PBS for 15 min. Then the cells were blocked in 1.5% bovine serum albumin (BSA), 0.1% Tween 20 in PBS for 1 h and incubated anti-a-tubulin antibody (Thermo Fisher Scientific, Waltham MA) in 1% bovine serum albumin (BSA), 0.1% Tween 20 in PBS overnight at 4 °C. The following day, cells were washed and incubated with Alexa Fluor 647 goat anti mouse IgG (Molecular Probes, Eugene OR) in dark for 1 h at room temperature, followed by the addition of Prolong Diamond Antifade reagent with DAPI (Invitrogen, Carlsbad, CA) and subsequent mounting with slides. Images depicted in figures were obtained with a Keyence BZ- X700 microscope (Keyence, Osaka Japan).

[00280] Detection of apoptosis. MDA-MB-231 and MDA-MB-468 Cells were seeded in

6- well plates (2 x l0 ⁵ /well). After incubating overnight, cells were treated with 100 nM compound l7ya for 24 h, 48 h and 72 h. A dose dependent investigation was carried out by treating cells with increasing doses for 48 h. Cells were then washed twice with PBS and 10 ⁵ cells were suspended in 200 ul Annexin V-FITC binding buffer (eBioscience, Grand Island, NY). 185 pl cell suspension were added 5 mΐ Annexin V-FITC and 10 mΐ propidium iodide cell suspension, after mixture and incubation for 10 min at room temperature, the cells were analyzed by a Bio-Rad ZE5 cell analyzer (Bio-rad, Hercules, CA).

[00281] Cell cycle analysis, Western blotting, In vivo orthotopic xenograft model.

[00282] All animal studies were carried out in adherence to the NIH Principles of

Laboratory Animal Care and protocols approved by the Institutional Animal Care and Use Committee at the University of Tennessee Health Science Center. Female Nod-Scid-g (NSG) mice at 5-6 weeks of age were housed in a specific pathogen free environment with a l2:l2-hour light-dark cycle. Temperature was maintained at 20-26 °C and the relative humidity was maintained at 30-70%. 2.5 x 10 ⁵ MDA-MB-231 cells in 10 mΐ of HBSS were surgically inoculated into the left and right inguinal mammary gland fat pads of NSG mice as described by Pfeffer et al.,“Comprehensive analysis of microRNA (miRNA) targets in breast cancer cells,” J. Biol. Chem., 2013, 288, 27480-27493, hereby incorporated by reference. Mice were inspected weekly for tumor appearance until the average tumor size reached 100 mm ³ . Then the mice were randomly divided into 3 groups (n=5 per group) and drug treatment was started. The control group was administered with vehicle (1:1 ratio of PEG 300: water) orally, drug treatment groups were administered 5 mg/kg compound l7ya or 10 mg/kg compound l7ya orally five times a week, respectively. Primary tumor size was monitored twice a week using a digital caliper and body weight of the mice was recorded during the treatment. The tumor volume was calculated using the formula volume = (width ² x length)/2. After 33 days treatment, when the tumor size in the vehicle group reached 1000 mm ³ , tumors and major organs were imaged and collected in 10% buffered formalin phosphate solution for histological analysis. Another similar orthotopic xenograft model for comparing the efficacy of compound l7ya with paclitaxel was performed as described above. The mice were randomized into 3 groups with 8 mice per group. Identically, the control group was administered with vehicle (1:1 ratio of PEG 300: water) orally, paclitaxel group was administered 12.5 mg/kg paclitaxel via intraperitoneal injection every other day and compound l7ya group was administered 12.5 mg/kg compound l7ya orally five times a week, and tumors and major organs were collected in 10% buffered formalin phosphate solution for histological analysis when the tumor size in the vehicle group reached 1000 mm ³ .

[00283] Experimental lung metastasis model: 7-8-week-old NSG mice were used to investigate the efficacy of compound l7ya to inhibit the metastasis of TNBC. 2 x 10 ⁵ MDA-MB- 231 cells in 100 pl of HBSS was inoculated into each mouse via tail vein injection. Vehicle, 10 mg/kg compound l7ya and 10 mg/kg paclitaxel treatments with the same dose frequency of the orthotopic xenograft model were started after 24 h. Animal health and body weight were monitored weekly during the treatment. After 23 days, the mice were sacrificed and all major organs were imaged and collected in 10% buffered formalin phosphate solution for subsequent histology and immunohistochemistry analysis.

[00284] Histology and immunohistochemistry (IHC) analysis: Fixed tumors and organs were embedded in paraffin and several section slides were cut for further Hematoxylin/eosin (H&E) staining and IHC staining. H&E staining and IHC staining were carried out as previously described. Primary antibodies used in IHC staining included rabbit anti-Ki67 (1:400), rabbit anti- CD31 (1:100), rabbit anti-cleaved Parp (1:50) and rabbit anti-cleaved caspase 3 (1:200) (#9027; #77699; #5625; #9661, Cell Signal Technology, Danvers MA), and biotinylated horse anti-rabbit IgG antibody (BA-1100, Vector Laboratories Inc., Burlingame, CA) was used as the secondary antibody. Anti-mitochondria IHC staining was performed to visualize the metastasis of MDA- MB-231 cells in experimental lung metastasis model. Images were acquired with a Keyence BZ- X700 microscope.

[00285] Compound l7ya extenuates the proliferation of different breast cancer cells. Compound l7ya previously was tested in a panel of melanoma cancer cell lines with an IC50 of 10 nM as described by Li el al,“Discovery of novel 2-aryl-4-benzoyl-imidazole (ABI-III) analogues targeting tubulin polymerization as antiproliferative agents,” J. Med. Chem ., 2012, 55 7285-7289. Compound l7ya was evaluated to determine whether it could also inhibit the growth of breast cancer cells using MTS assay. Table 2 showed that compound l7ya had anti proliferative effect against breast cancer cell lines, especially in TNBC. The testing incorporated two well-known tubulin inhibitors, colchicine and paclitaxel, to compare the efficacy of compound l7ya against TNBC cell growth. The results of the test are illustrated in Figure 16. All three tubulin inhibitors were potent in inhibiting the proliferation of TNBC. Colony formation assay is always used for assessing the cell proliferation by determining the colony growth from microcolonies to macrocolonies. The colony formation results showed that compound l7ya attenuated the capacity of proliferation of MDA-MB-231 and MDA-MB-468 cells in a dose- dependent manner.

[00286] Compound l7ya inhibited TNBC cells migration and invasion. The effect of compound l7ya on the migration and invasion of TNBC cells after 24 or 48 hours of drug treatment was investigated. Figure 17 illustrates the results. Compound l7ya inhibited the cells ability to migrate through a membrane insert in the presence of 16 nM concentration, showing the similar potency as of colchicine. Likewise, Compound l7ya reduced the TNBC cells capacity to invade through the matrigel-coated membrane. To further confirm these results, a scratch assay was performed using paclitaxel and colchicine as positive control. At a dose of 16 nM, Compound l7ya, colchicine and paclitaxel showed effective inhibition of cell migration. Based on these findings, we concluded that Compound l7ya suppressed cell migration significantly, emphasizing a potential role Compound l7ya plays in inhibiting the TNBC metastasis.

[00287] Compound l7ya interfered with microtubule assembly and mitotic spindle organization: Compound l7ya was used with immunofluorescence staining to visualize the microtubule network and compared with known microtubule-destabilizing agent colchicine and microtubule-stabilizing agent paclitaxel. TNBC cells in negative control group showed intact microtubule fibers and organization of microtubules. Figure 18 illustrates these results. Treatment with paclitaxel resulted multipolar spindles with highly condensed chromosomes due to the enhance of tubulin polymerization in TNBC cells. Like the treatment of colchicine, cells treated with Compound l7ya had shrunken and the cell shape was changed from spindle to round and irregular, which confirmed that Compound l7ya targeted the tubulin and interfere the tubulin polymerization.

[00288] Compound l7ya induced increased apoptosis in TNBC cells: Since many tubulin inhibitors were reported to have pro-apoptotic effect on cancer cells, compound l7ya was studied to determine the effect on apoptosis induction in TNBC cells. MDA-MB-231 cells were treated with 100 nM Compound l7ya in a time-dependent manner. Compound l7ya induced the cells to apoptosis as illustrated in Figure 19. Cells were treated with increasing concentrations of compound l7ya for 48h. Compound l7ya initiated apoptotic cell death in a dose-dependent manner, and thus caused apoptosis of TNBC cells.

[00289] Compound l7ya inhibited TNBC tumor growth and metastasis in vivo. To validate in vitro results, the anti-cancer activity of compound l7ya in orthotopic TNBC mouse model was studied to determine if the potent effect of compound l7ya in vitro could be observed in vivo. After 33 days of treatment, treatment with compound l7ya inhibited TNBC tumor growth in a dose dependent manner without interfering with the body weight of mice. The results are illustrated in Figure 20. The efficacy of compound l7ya in mice bearing TNBC tumors was shown by reduced tumor size and tumor weight compared with the control (vehicle treated) mice. The shape of all tumors in these three groups furthered showed that tumor size decreased with as the dose of compound l7ya increased. The H & E staining of the tumor sections determined that compound l7ya induced TNBC tumor necrosis, which is similar to what was observed in vitro. A study compared the efficacy of compound l7ya with paclitaxel in the same model since paclitaxel is one of the standard cares for TNBC treatment in clinic. Both compound l7ya and paclitaxel significantly regressed the tumor size and tumor weight. The results are illustrated in Figure 21. The overall tumor picture confirmed that tumor size decreased in both compound l7ya and paclitaxel treated mice. Although compound l7ya was less potent than paclitaxel in regressing the tumor growth, it was better to dissolve and administer in the treatment of cancer compared to the paclitaxel. H & E staining of tumors in a comparison study further suggested that both compound l7ya and paclitaxel induced TNBC tumor necrosis. A tail vein study determined the efficacy of compound l7ya in anti-metastasis of TNBC in vivo. Figure 22 and Figure 23 demonstrated that the lungs in vehicle group were full of metastasis (indicated by yellow arrow), while the lungs in compound l7ya and paclitaxel group had little, which suggested that compound l7ya significantly reduced metastasis of TNBC. Similar results were found in liver, kidney and spleen tissues, which further demonstrated that compound l7ya inhibited the metastasis of TNBC.

EXAMPLE 3

[00290] In addition to the materials and methods described above, the following examples utilized the following procedures.

[00291] Cell cycle analysis. To determine the cell cycle profile in the mitotic phase (especially G2 and M phase), cells were treated with colchicine, paclitaxel, and compound l7ya. The cells were harvested by trypsinization, fixed, permeabilized, stained with anti-phospho- Histone H3-AlexaFluor® 488 antibody on ice for 1 h in the dark and incubated with freshly prepared propidium iodide/Rnase solution for 30 min at room temperature in the dark according to the manufacturer’s protocol (#FCCH0225l03, EMD Millipore Corp., Burlington MA). Stained cells were then analyzed by Bio-Rad ZE5 cell analyzer (Bio-Rad, Hercules, CA). Data were processed, and graphs generated using FlowJo (FlowJo, LLC, Ashland, OR).

[00292] Western Blotting. Cells were incubated with increasing doses of compound l7ya and 100 nM colchicine and paclitaxel for 24 h, or 100 nM compound l7ya for 24h, 48 h, and 72 h as time-dependent investigation. Then the cells were harvested, washed with ice-cold PBS, lysed in RIPA buffer (25 nM Tris pH 7.6, 150 nM NaCl, 1% NP-40, 1% sodium deoxycholate, 0.1% SDS) with Halt™ protease and phosphatase inhibitor (Thermo Fischer Scientific) and then centrifuged at 13000 rpm at 4 °C for 10 min. Protein in the supernatant was determined by BCA Protein Assay (Thermo Fischer Scientific). Equal amounts of each denatured protein sample were loaded and separated by SDS-PAGE gradient gels (Bio-Rad, #456-1083). Protein was wet- box transferred to PVDF membranes. The membranes were then blocked in 5% non-fat milk in TBST solution at room temperature for 1 h, incubated with primary antibodies overnight at 4 °C and bound with secondary antibody for 1 h subsequently. The following primary antibodies were used: rabbit anti-Poly (ADP-ribose) polymerase (PARP, 1:1000), rabbit anti-cleaved PARP (1:1000), rabbit anti-cleaved-capase-3 (1:1000) and rabbit anti-GAPDH HRP conjugate (#9532; #5625; #9661; #3683, Cell Signal Technology, Danvers, MA). Bound proteins were detected using Clarity™ Western ECL Substrate (Bio-Rad, #1705060) and visualized by ChemiDoc-It2 Imager system (UVP, LCC, Upland, Ca).

[00293] In vivo orthotoxic xenograft model. All animal studies were carried out in adherence to the NIH Principles of Laboratory Animal Care and protocols approved by the Institutional Animal Care and Use Committee at the University of Tennessee Health Science Center. Female Nod-Scid-g (NSG) mice at 5-6 weeks of age were housed in a specific pathogen free environment with a l2:l2-hour light-dark cycle. Temperature was maintained at 20-26 °C and the relative humidity was maintained at 30-70%. 2.5 x 10 ⁵ MDA-MB-231 cells in 10 pl of HBSS were surgically inoculated into the left and right inguinal mammary gland fat pads of NSG mice as described by Pfeffer et al.,“Comprehensive analysis of microRNA (miRNA) targets in breast cancer cells,” J. Biol. Chem., 2013, 288, 27480-27493, hereby incorporated by reference. Mice were inspected weekly for tumor appearance until the average tumor size reached 100 mm ³ . Then the mice were randomly divided into 5 groups (n=l4 in vehicle control group, n=8 in drug treated group) and drug treatment was started. The control group was administered with vehicle (1:1 ratio of PEG 300: water) orally, drug treatment groups were administered 5 mg/kg compound l7ya, 10 mg/kg compound l7ya, 12.5 mg/kg compound l7ya orally five times a week, and 12.5 mg/kg paclitaxel via intraperitoneal injection every other day, respectively. Primary tumor size was monitored twice a week using a digital caliper and body weight of the mice was recorded during the treatment. The tumor volume was calculated using the formula volume = (width ² x length)/2. After 18 days treatment, when the tumor size in the vehicle group reached 1000 mm ³ , tumors and major organs were imaged and collected in 10% buffered formalin phosphate solution for histological analysis.

[00294] Compound l7ya extenuated the proliferation of different breast cancer cells and interfered microtubule assembly and mitotic spindle organization. Compound l7ya previously was tested in a panel of melanoma cancer cell lines with an average IC50 of 4 nM, and now was evaluated to determine whether compound l7ya could inhibit the growth of breast cancer cells using MTS assay. The results demonstrated that compound l7ya had an anti-proliferative effect against breast cancer cell lines, with IC ₅₀ value of 14 nM in HER2-positive breast cancer cells and 8 nM in TNBC cells. Tubulin-destabilizing colchicine and tubulin- stabilizing agent paclitaxel were incorporated to compare the efficacy of colchicine, paclitaxel, and compound l7ya against TNBC cell growth. (See Figure 58A for MDA-MB-231 and Figure 58B for MDA- MB-486). All three tubulins inhibitors were potent in inhibiting the proliferation of TNBC, where IC ₅₀ values of compound l7ya ranged from 8.2-9.6 nM. Colony formation assay results demonstrated that compound l7ya attenuated the capacity of the proliferation of TNBC cells in a dose dependent manner. (See Figure 59A for MDA-MB-231 and Figure 59B for MDA-MB- 486). Paclitaxel showed the most remarkable effect with relative percentage of colonies covering 27.5% compared to colchicine (100%) at 8 nM and compound l7ya (55%) was more potent than colchicine. In MDA-MB-468 cells, reductions in colony formation were observed in colchicine (51%), paclitaxel (7.4%), and compound l7ya (37.7%) at the dose of 8 nM, which indicated that all three tubulin inhibitors inhibited the colony formation of TNBC cells.

[00295] Immunofluorescence staining was used to visualize the microtubule network in comparison with colchicine and paclitaxel. TNBC cells in the negative control group showed intact microtubule fibers and organization of microtubules, as illustrated in Figure 60. Treatment with paclitaxel resulted in multipolar spindles with highly condensed chromosomes due to the increase of tubulin polymerization in TNBC cells. Fike the treatment of colchicine, cells treated with compound l7ya has shrunken and the cell shape was changed from spindle to round and irregular, that confirmed compound l7ya targeted tubulin and interfered with tubulin polymerization.

EXAMPLE 4

[00296] Compound l7ya inhibited TNBC cell migration and invasion. The example focused on the effect of compound l7ya on the migration and invasion of TNBC cells after 24 or 48 hours of treatment. Compound l7ya inhibited TNBC cells ability to migrate through a membrane insert in the presence of 16 nM concentration by an average migration rate of 40% in MDA-MB-231 cells and 34% in MDA-MB-468 cells as compared to a control group (migration rate 100%) as illustrated in Figure 61. Compound l7ya reduced the TNBC cells capacity to invade through the Matrigel-coated membrane with an average invasion rate of 55% and 36% in MDA-MB-231 and MDA-MB-468 cells, respectively, when invasion rate of the control group was set as 100%. The results are illustrated in Figure 62. A scratch assay was performed using paclitaxel and colchicine as positive controls. At a dose of 16 nM, compound l7ya, colchicine, and paclitaxel showed effective inhibition of cell migration as illustrated in Figure 63A for MDA-MB-231 and Figure 63B for MDA-MB-486. After 24 hours, the average migration rates of DMSO, colchicine, paclitaxel, and compound l7ya treated MDA-MB-231 cells were 100%, 67.3%, 13.3%, and 44.9%, respectively. Similarly, after 48 hours treatment with colchicine, paclitaxel, and compound l7ya were able to reduce the migration of MDA-MB-231 cells with average migration rates of l5.8%m 14.5%, and 17.9%, respectively. The findings concluded that compound l7ya significantly suppressed cell migration.

EXAMPLE 5

[00297] Compound l7ya blocks TNBC cells in G2/M phase and induced cell apoptosis. Microtubule dynamics play a significant role in cell division. Its disruption may lead to the mitotic arrest of growing cells in metaphase and ultimately cause cell death. In this example it was determined that compound l7ya can affect cell cycle arrest. A flow cytometry analysis was conducted of cells treated for 24 hours with 100 nM colchicine, 100 nM paclitaxel, and different concentrations of compound l7ya. Different compounds showed divergent effects on the cell cycle progression in different cells lines. Compound l7ya treatment induced the accumulation of MDA-MB-231 cells in the G2 and M phase with a reduction in the population of cells in the Gl and S phase in a dose dependent manner. Colchicine and paclitaxel, employed as positive controls, also arrested MDA-MB-231 cells in G2/M phase as illustrated in Figure 64A. Compound l7ya induced a G2 phase arrest in MDA-MB-468 cells and reduced the cell population of the Gl phase, while it had little effect in the percentage of cells in S phase as illustrated in Figure 64B. A small increase of cells in the M phase was observed. Colchicine arrested MDA-MB-468 cells in G2 phase, paclitaxel arrested cells in both G2 and M phase as illustrated in Figure 64B. Compound l7ya concentration resulted in a large accumulation of cells in G2/M phase starting with 20 nM in MDA-MB-231 cells, 50 nM in MDA-MB-468 cells, with maximum accumulation observed by 100 nM. Compound l7ya thus induced G2/M phase arrest of TNBC cells, leading to growth inhibition.

[00298] The pro-apoptotic effect on TNBC cells by compound l7ya was studied. The effect of compound l7ya on apoptosis induction in TNBC cells was studied using Annexn V- FITC-PI double staining method. MDA-MB-231 and MDA-MB-468 cells were treated with increasing concentrations of compound l7ya for 24 h. Quantitatively, compound l7ya initiated apoptotic cell death in a dose dependent manner, indicated by the appearance of Annexin-WPT cells, Annexin-V ⁺ /PI ⁺ cells and Annexin-V7PI ⁺ cells shown in the representative histograms of Figures 65A-B. The potency of compound l7ya to induce TNBC cell apoptosis was identical to colchicine, but higher than paclitaxel. The results illustrated that MDA-MB-231 (Figure 66A) and MDA-MB-468 (Figure 66B) cell treated with 100 nM of compound l7ya for 24, 48, and 72 hours underwent apoptosis in a time-dependent manner.

[00299] Caspases and PARP play an important role in the initiation and execution of programmed cell death. We determined the effect of compound l7ya on whether it triggered apoptotic cell death through regulating caspase-3/PARP pathway, expression of cleaved-caspase- 3, and cleaved PARP in TNBC cells treated with compound l7ya as analyzed by Western blotting. The results demonstrated that the expression of cleaved-caspase-3 and cleaved-PARP were increased in a dose dependent manner after 24 hours of treatment of compound l7ya, although their expression were lower than those in paclitaxel-treated group both in MDA-MB- 231 (Figure 67 A) and MDA-MB-468 (Figure 67B) cells. Colchicine was also able to induce the upregulation of cleaved-caspase-3 and cleaved-PARP in MDA-MB-468 cells after 24 hours of treatment. Compound l7ya increased cleaved-caspase-3 and cleaved-PARP in a time dependent manner as illustrated in Figure 68. To confirm the effect of compound l7ya on the expression of cleaved-caspase-3 and cleaved-PARP in the protein level, the caspase 3/7 activity was evaluated on MDA-MB-231 and MDA-MB-468 cells using the Caspase Glo 3/7 assay system. The results are illustrated in Figure 69. Colchicine and paclitaxel were used as positive controls. Compared to the cells in the control group, compound l7ya, colchicine, and paclitaxel displaced up to 4-fold higher caspase 3/7 activity, that is consistent with enhanced apoptosis induction of TNBC cells.

EXAMPLE 5

[00300] Compound l7ya inhibits TNBC tumor growth in vivo. Compound l7ya affects the in vivo growth of human cancer cell lines, as investigated by the anticancer activity in orthotopic TNBC mouse model. Since paclitaxel is one of the widely used chemotherapeutics for TNBC treatment in the clinic; it was incorporated as a comparison. NSG mice bearing MDA- MB-231 xenografts were treating with vehicle, 5 mg/kg Compound l7ya, 10 mg/kg compound l7ya, 12.5 mg/kg compound l7ya, and 12.5 mg/kg paclitaxel for 18 days. As compared to the vehicle treated group, the percentage increase of tumor size was significantly decreased in 10 mg/kg and 12.5 mg/kg compound l7ya and paclitaxel-treated groups, while the 5 mg/kg oral administration showed relatively weak tumor growth inhibition as illustrated in Figure 70. During treatment, no loss of body weight was observed for compound l7ya treated groups an indication of lack of toxicity. While 12.5 mg/kg paclitaxel treatment decreased mice body weight significantly, suggesting accumulated toxicity of paclitaxel during the treatment as illustrated in Figure 71. Compared to the vehicle-treated control group, compound l7ya at 5 mg/kg reduced average tumor volume and tumor weight by 38.66% and 26.83%, respectively. Compound l7ya at 10 mg/kg decreased average tumor volume and weight by 55.73% and 56.10%, respectively, and a dose of 12.5 mg/kg decreased average tumor volume and tumor weight by 61.32% and 62.6%, respectively. The results indicated that compound l7ya inhibited TNBC tumor growth in a dose dependent manner as illustrated in Figures 72 and 73. The group treated with 12.5 mg/kg compound l7ya was comparable to paclitaxel in average final tumor weight (0.46 g vs. 0.38 g). The efficacies of compound l7ya and paclitaxel against tumors were evident on tumor images, where treatment displayed significant reduction in tumor volume compared to the vehicle group.

EXAMPLE 6

[00301] Compound l7ya induces tumor necrosis, anti-angiogenesis, and apoptosis in vivo. Tumors were excised stained with H&E and the expression of cell proliferation marker Ki67, prognostic angiogenic marker CD31, apoptotic markers cleaved-PARP, and cleaved-caspase-3 were determined through IHC staining. Natural necrosis happens inside the tumor caused by internal hypoxia, both H&E and IHC were imaged near the margin of the tumor. Both compound l7ya and paclitaxel treatment increased the number of necrotic tumor cells with pyknosis, indicated by nuclear shrinkage. Necrotic cells increased with the dose of compound l7ya from 5 mg/kg to 12.5 mg/kg. An increased percentage of necrotic area of whole tumors was observed with the compound l7ya treated group as compared to the vehicle treated counterpart as illustrated in Figure 74. Tumors in the compound l7ya (12.5 mg/kg) treated group had 49.5% of necrotic area, comparable to the percentage of paclitaxel induced tumor necrosis (41.5%), that demonstrated the potency of compound l7ya to induce tumor necrosis, which was more efficacious to induce tumor necrosis than paclitaxel. IHC analysis demonstrated that compound l7ya treatment significantly decreased the number of Ki67-positive cells (Figure 75) and CD31- positive cells (Figure 76) in tumor tissues, demonstrated by 71% and 87% decrease in compound l7ya (12.5 mg/kg) treated tumors compared to the tumors in the vehicle control group, respectively, which suggested that compound l7ya inhibited the proliferation of TNBC cells and disrupt tumor vasculature in vivo. The results demonstrated that there was a clear dose-dependent increase of cells expressing the cleaved-PARP (Figure 77) and cleaved-caspase-3 (Figure 78), that confirmed the increased apoptosis due to treatment with compound l7ya. Tumor growth suppression, tumor vasculature disruption, and apoptotic cell death induction after paclitaxel treatment were evident from IHC histological results and the anticancer activity of paclitaxel was similar to compound l7ya. Taken together, the results demonstrated that compound l7ya exhibit similar anticancer activity as paclitaxel that suppressed tumor growth significantly at the in vivo level.

EXAMPLE 7

[00302] Compound l7ya inhibited TNBC spontaneous metastasis and cancer in lung metastasis mouse model. The experiment tested the inhibition of spontaneous lung metastasis of mice in vehicle, compound l7ya at 5 mg/kg, 10 mg/kg, and 12.5 mg/kg, and paclitaxel 12.5 mg/kg. In the vehicle group, the lung metastasis foci were increased in the lung lobe (four mice had large metastasis, 10 mice had more than five lung metastases). Compound l7ya inhibited the spontaneous metastasis of TNBC cells with some few metastasis foci in 5 mg/kg treated group (six mice with few metastases, two mice without metastases), one or two small metastasis foci in 10 mg/kg treated group (four mice with few metastases, four mice without metastases), a metastasis or none observed in the 12.5 mg/kg treated group (one mouse with one lung metastasis, seven with no metastasis), and no metastasis was observed in the 12.5 mg/kg paclitaxel treated group (all eight mice had no metastasis), indicating the significant role of compound to inhibit metastasis of TNBC.

[00303] Since compound l7ya decreased the number and size of TNBC metastases in an orthotopic mouse model, an experimental lung metastasis model was used to evaluate the anti metastasis effect of the compound. Due to the weakness of mice after tail vein inoculation, 10 mg/kg of paclitaxel and 10 mg/kg of compound l7ya were chosen as the dosage for this study. After 22 days of treatment, mice were euthanized and lungs, livers, kidneys, and spleens were harvested, fixed, and examined by anti-mitochondria IHC and H&E staining. The lungs in the vehicle group were full of metastasis (indicated by brown dots), while the lungs in the compound l7ya and paclitaxel treated groups exhibited significantly inhibited lung metastasis of TNBC. Results of the liver and spleen tissues were similar. Fever metastases were detected in the kidneys of vehicle mice, while the kidneys of the compound l7ya and paclitaxel treated groups were clear, that demonstrated that compound l7ya inhibited metastases of TNBC. Body weights and physical activities of mice were normal in the compound l7ya treated group, while body weights and physical activities of mice in the paclitaxel treated group were slightly decreased, demonstrating the toxicity of paclitaxel during long term treatment. H&E staining showed that multiple metastases with varying sized were observed in the lung, liver, kidney, and spleen of vehicle mice, whereas the metastases of compound l7ya and paclitaxel treated mice were sparse and smaller. The lung results indicated that compound l7ya showed comparable efficacy to paclitaxel in suppressing metastasis of TNBC cells without significant toxicity in mice.
