[0001] This application claims priority of US provisional application 62/216, 150, filed September 9, 2015, the entire disclosure of which is hereby incorporated herein by reference.

FIELD OF THE INVENTION

[0002] The invention relates to the use of chemical modulators of PP2A, comprising ring constrained diarylamino sulfonamides to treat diseases such as cancer, neurodegenerative disease and other disorders.

BACKGROUND

[0003] The FOXO (Forkhead transcription factors, Class O) proteins are a group of transcription factors involved in control of a variety of physiological, metabolic and developmental pathways. They are downstream effectors in a number of signaling pathways including insulin and growth factor signaling; they are also regulated by oxidative stress and nutrient deprivation. Cellular processes affected by FOXO activity include cell cycle control, differentiation, proliferation and apoptosis. Disregulation of FOXO mediated processes has been implicated in a number of pathologies including tumorigenesis, inflammation, diabetes and neurodegenerative conditions amongst others. Activity of FOXO transcription factors are controlled in part by their sub-cellular localization, in particular their localization to the nucleus from the cytosol, and their subsequent transcriptional activation.

[0004] Four FOXO proteins designated FOXOl, FOX03a, FOX04 and FOX06 are present in human cells and their activity is controlled by a variety of mechanisms including stability (proteolytic cleavage), sub-cellular localization and transcriptional activation. Activity of the first three members of the family is controlled by cytosolic-nuclear translocation.

[0005] FOXOl regulates expression of a number of genes that play critical roles in cell cycle and apoptosis. A pivotal regulatory mechanism of FOXO is reversible

phosphorylation, catalyzed by kinases and phosphatases. Phosphorylation of FOXOl is associated with 14-3-3 binding and cytosolic localization, whereas dephosphorylated FOXOl translocates to the nucleus and is transcriptionally active.

[0006] Protein phosphatase 2A is one of the four major serine threonine phosphatases and is implicated in the negative control of cell growth and division. Protein phosphatase 2A holoenzymes are heterotrimeric proteins composed of a structural subunit A, a catalytic subunit C, and a regulatory subunit B. The PP2A heterotrimeric protein phosphatase is a ubiquitous and conserved phosphatase with broad substrate specificity and diverse cellular functions. Among the targets of PP2A are proteins of oncogenic signaling cascades, such as Raf, MEK, and AKT.

[0007] PP2 A interacts directly with FOXOl and dephosphorylates FOXOl . Inhibition of PP2 A phosphatases rescues FOXOl -mediated cell death by regulating the level of the pro- apoptotic protein BIM. In addition, PP2 A directly regulates FOX03a subcellular localization and transcriptional activation. Without wishing to be held to any particular theory, it may be that the compounds described herein promote apoptosis by acting on FOXO transcription factors via activation of PP2A.

[0008] Myc proteins (c-myc, Mycn and Mycl) target proliferative and apoptotic pathways vital for progression in cancer and they are overexpressed and deregulated in many human cancers. The control of Myc abundance through protein degradation has attracted considerable interest and Ser-62 phosphorylation by a number of kinases has been shown to stabilize the protein. PP2A is responsible for Ser-62 dephosphorylation which primes the protein for ubiquitylation and degredation, thus PP2A functions as a negative regulator of Myc.

[0009] Prostate cancer is the second leading cause of cancer death in men in America, behind lung cancer. According to the American Cancer Society, approximately 1 man in 36 will die of prostate cancer. Male hormones, specifically testosterone, fuel the growth of prostate cancer. By reducing the amount and activity of testosterone, the growth of advanced prostate cancer is slowed. Endocrine therapy, known as androgen ablation, is the first line of treatment for metastatic prostate cancer. Androgen deprivation therapy for metastatic prostate cancer results in tumor regression and symptomatic improvement in the majority of patients. However, metastatic prostate cancer inevitably progresses despite castrate levels of serum testosterone. Several new therapies have been approved for patients with castration-resistant prostate cancer (CRPC); however, none are curative and tumors ultimately develop resistance. To combat CRPC new approaches and novel therapies are required.

[0010] Breast cancer can affect both men and women. Breast cancer is the most prevalent cancer in women, after skin cancers, with about 1 in every 8 women expected to develop invasive breast cancer at some point. One subset of breast cancer expresses the androgen receptor (AR), which has been implicated as a therapeutic target in that subset. About 10- 20% of breast cancers— more than one out of every 10— are found to be triple-negative. "Triple negative breast cancer" refers to a breast cancer that does not contain estrogen receptors, progesterone receptors, or human epidermal growth factor receptor 2 (HER2). This means that the growth of the cancer is not supported by the hormones estrogen and progesterone, nor by the presence of too many HER2 receptors. Therefore, triple-negative breast cancer does not respond to hormonal therapy (such as tamoxifen or aromatase inhibitors) or therapies that target HER2 receptors, such as Herceptin (chemical name: trastuzumab). While these tumors are often treatable, the chemotherapy is not targeted, and response durations are short. For doctors and researchers, there is intense interest in finding new medications that can treat breast cancer.

[0011] The compounds described herein exhibit anti-proliferative effects and are useful as monotherapy in cancer treatment. Additionally, they can be used in combination with other drugs to restore sensitivity to chemotherapy where resistance has developed.

[0074] The compounds described herein contain three or more asymmetric centers and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms which may be defined in terms of absolute stereochemistry as (R)- or (S)-. The present invention is meant to include all such possible diastereomers as well as their racemic and optically pure forms. Optically active (R)- and (S)- isomers may be prepared using homo-chiral synthons or homo-chiral reagents, or optically resolved using conventional techniques. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended to include both (£)- and {∑)- geometric isomers. Likewise, all tautomeric forms are intended to be included.

[0075] The graphic representations of racemic, ambiscalemic and scalemic or

enantiomerically pure compounds used herein are a modified version of the denotations taken from Maehr J. Chem. Ed. 62, 114-120 (1985): simple lines provide no information about stereochemistry and convey only connectivity; solid and broken wedges are used to denote the absolute configuration of a chiral element; solid and broken bold lines are geometric descriptors indicating the relative configuration shown but not necessarily denoting racemic character; and wedge outlines and dotted or broken lines denote enantiomerically pure compounds of indeterminate absolute configuration. For example, the graphic representation

indicates either, or both, of the two trans: trans enantiomers:

in any ratio, from pure enantiomers to racemates. The graphic representation:

indicates a single enantiomer of unknown absolute stereochemistry, i.e. it could be either of the two preceding structures, as a substantially pure single enantiomer. And, finally, the representation:

indicates a pure (lR,2R,6,S)-2,6-diaminoheterocyclyl-4-ol. For the purpose of the present disclosure, a "pure" or "substantially pure" enantiomer is intended to mean that the enantiomer is at least 95% of the configuration shown and 5% or less of other enantiomers. Similarly, a "pure" or "substantially pure" diastereomer is intended to mean that the diastereomer is at least 95% of the relative configuration shown and 5% or less of other diastereomers. In the text describing the stereochemistry of the examples, the convention of Chemical Abstracts is used. Thus "(lR,2R,6S)-re/-" indicates that the three chiral centers are in that relative relationship, which would be depicted in a structural diagram by solid bold and dashed lines, whereas "(1R,2R,6,S)" without the "re/" indicates a single enantiomer of that absolute configuration, which would be depicted in a structural diagram by solid and broken wedges.

[0076] It may be found upon examination that certain species and genera are not patentable to the inventors in this application. In this case, the exclusion of species and genera in applicants' claims are to be considered artifacts of patent prosecution and not reflective of the inventors' concept or description of their invention, which encompasses all members of the genus I that are not in the public's possession.

Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium cations and carboxylate, sulfonate and phosphonate anions attached to alkyl having from 1 to 20 carbon atoms.

[0079] Also provided herein is a pharmaceutical composition comprising a compound disclosed above, or a pharmaceutically acceptable salt form thereof, and a pharmaceutically acceptable carrier or diluent.

[0080] While it may be possible for the compounds of formula I to be administered as the raw chemical, it is preferable to present them as a pharmaceutical composition. According to a further aspect, the present invention provides a pharmaceutical composition comprising a compound of formula I or a pharmaceutically acceptable salt thereof, together with one or more pharmaceutically carriers thereof and optionally one or more other therapeutic ingredients. The carrier(s) must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.

[0081] The formulations include those suitable for oral, parenteral (including subcutaneous, intradermal, intramuscular, intravenous and intraarticular), rectal and topical (including dermal, buccal, sublingual and intraocular) administration. The most suitable route may depend upon the condition and disorder of the recipient. The formulations may

conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing into association a compound of formula I or a pharmaceutically acceptable salt thereof ("active ingredient") with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into

association the active ingredient with liquid carriers or finely divided solid carriers or both and then, if necessary, shaping the product into the desired formulation.

[0082] Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a

predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be presented as a bolus, electuary or paste.

[0083] A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, lubricating, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated so as to provide sustained, delayed or controlled release of the active ingredient therein.

[0084] Formulations for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient.

Formulations for parenteral administration also include aqueous and non-aqueous sterile suspensions, which may include suspending agents and thickening agents. The formulations may be presented in unit-dose of multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of a sterile liquid carrier, for example saline, phosphate-buffered saline (PBS) or the like, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

[0085] It will be recognized that the compounds of this invention can exist in radiolabeled form, i.e., the compounds may contain one or more atoms containing an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Radioisotopes of hydrogen, carbon, phosphorous, fluorine, and chlorine include ² H, H, ¹ C, ¹⁴ C, ¹⁵ N, ⁵ S, ¹⁸ F, and ⁶ C1, respectively. Compounds that contain those radioisotopes and/or other radioisotopes of other atoms are within the scope of this invention. Tritiated, i.e. H, and carbon-14, i.e., ¹⁴ C, radioisotopes are particularly preferred for their ease in preparation and detectability. Compounds that contain isotopes ^U C, ¹ N, ¹⁵ 0 and ¹⁸ F are well suited for positron emission tomography. Radiolabeled compounds of formula I of this invention and prodrugs thereof can generally be prepared by methods well known to those skilled in the art. Conveniently, such radiolabeled compounds can be prepared by carrying out the procedures disclosed in the Examples and Schemes by substituting a readily available radiolabeled reagent for a non-radiolabeled reagent.

[0090] Cancers may be solid tumors that may or may not be metastatic. Cancers may also occur, as in leukemia, as a diffuse tissue.

[0091] The compounds described herein can also be administered in combination with existing methods of treating cancers, for example by chemotherapy, irradiation, or surgery. Thus, there is further provided a method of treating cancer comprising administering an effective amount of a compound according to formula I to a patient, wherein a therapeutically effective amount of one or more additional cancer chemotherapeutic agents are administered to the patient.

[0092] Also provided herein is a method for treating diabetes in a patient, the method comprising administering to the patient a therapeutically effective amount of a compound of formula I.

[0093] Further provided herein is a method for treating an autoimmune disease in a patient, the method comprising administering to the patient a therapeutically effective amount of a compound of formula I. The autoimmune disease can be, for example, inflammatory bowel disease (IBD). Immune responses are constantly and tightly regulated and one important cellular component in maintaining self tolerance (i.e., prevention of autoimmunity) and tolerance of benign commensal gut flora are regulatory T cells (Treg). Treg can be subdivided into multiple phenotypes, but the most common are CD4+CD25+ T cells that express the transcription factor Foxp3. Foxp3 is a direct transcriptional target of FOXO proteins, particularly FOXOl and FOX03. Thus activation of FOXO proteins in naive T- cells promotes and directs differentiation to maintain a population of Treg cells.

[0094] Acute immune mediated rejection and chronic immune mediated rejection are key obstacles to successful solid organ transplantation. It is believed that these forms of rejection can be prevented/overcome by amplifying Treg number and or function.

Similarly, a common and morbid complication of allogeneic hematopoietic cell transplants (Allo-HCT) used to treat various malignant and non-malignant conditions, is graft versus host disease, in which the transplanted immune cells from the donor damage multiple organs in the recipient (most notably skin, gut, and liver). Increasing experimental and clinical data indicate that Tregs can be harnessed to prevent and or treat this disease process.

[0095] Thus compounds of the present invention are useful in treatment of autoimmune and related diseases, by activating FOXO proteins and inducing T cell differentiation to Tregs. Compounds may be administered therapeutically to subjects directly, or alternatively, T cells may be collected from a subject and differentiated ex vivo to Tregs as described by Taylor et al. [Blood 99, 3493-3499 (2002)].

[0096] Aspects of the invention include methods for treatment of autoimmune disease characterized by deficiency in Treg function comprising administering a therapeutically useful amount of compound of Formula I. The method can also include extraction of naive T-cells from a patient, differentiation of T-cells to Tregs ex vivo by treatment with a compound of Formula I, optionally supplemented with an FIDACi, followed by

administration of Tregs to patient with optional separation of compound of Formula I from Tregs prior to their administration. As stated above, autoimmune diseases that can be so treated include IBD, solid organ transplant rejection, and GvFID in allo-HCT

[0097] In some embodiments, the compounds can be administered to a patient to treat an autoimmune disorder, for example, Addison's disease, Amyotrophic Lateral Sclerosis, celiac disease, Crohn's disease, diabetes, eosinophilic fasciitis, Guillain-Barre syndrome (GBS), Graves' disease, Lupus erythematosus, Miller-Fisher syndrome, psoriasis, rheumatoid arthritis, ulcerative colitis, and vasculitis. In some embodiments, the compound provided herein can be used for treating a disease or disorder in a patient wherein the disease or disorder involves excessive or unregulated cellular proliferation, the method comprising administering to the patient a therapeutically effective amount of a compound of formula (I). Also provided herein is a method for treating a disease or disorder in a patient where the disease or disorder involves the dysregulation of the pi3K-AKT-FOXO signaling pathway, the method comprising administering to the patient a therapeutically effective amount of a compound of formula I.

[0098] Further provided herein is a method for treating a disease in a patient wherein the disease is characterized by proteotoxicity, including age onset proteotoxicity leading to neurodegeneration, the method comprising administering to the patient a therapeutically effective amount of a compound of formula I. Hyperphosphorylated Tau has been implicated as the pathogenic protein in several neurodegenerative diseases and furthermore PP2A has been shown to be an important phosphatase in reversing aberrant

phosphorylation of Tau; see for example Ludovic Martin et al, Tau protein phosphatases in Alzheimer's disease: The leading role of PP2A in Ageing Research Reviews 12 (2013) 39- 49; Miguel Medina and Jesus Avila, Further understanding of tau phosphorylation:

implications for therapy in Expert Rev. Neurotherapy, 15(1), 115-112 (2015) and Michael Voronkov et al, Phosphoprotein phosphatase 2A: a novel druggable target for Alzheimer's disease in Future Med Chem. 2011 May, 3(7) 821-833. Hyperphosphorylated alpha- Synuclein is a second exemplar of a toxic protein, and again PP2A has been shown to reverse its aberrantly phosphorylated state; see for example Kang-Woo Lee et al, Enhanced Phosphatase Activity Attenuates alpha- Synucleinopathy in a Mouse Model in Neurobiology of Disease, May 11, 2011, 31(19) 6963-6971. In some embodiments, the disease is selected from the group consisting of: Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, frontotemporal dementia, progressive supranuclear palsy, corticobasal degeneration and Pick's disease.

[0099] The compounds provided herein may further be used in a method for treating a mood disorder in a patient by administering to the patient a therapeutically effective amount of a compound of formula I. In some embodiments, the mood disorder is stress-induced depression.

[00100] Also provided herein is a method for treating acne vulgaris in a patient by administering to the patient a therapeutically effective amount of a compound of formula I.

[00101] Further provided herein is a method for treating cardiac hypertrophy in a patient by administering to the patient a therapeutically effective amount of a compound of formula I. In some embodiments, the cardiac hypertrophy is associated with a disease selected from hypertension, myocardial infarction, and valvular heart disease.

[00102] The compounds provided herein may further be used in a method for treating a viral infection in a patient by administering to the patient a therapeutically effective amount of a compound of formula I. Examples of viruses that may cause viral infections to be treated include, but are not limited to: a polyomavirus, such as John Cunningham Virus (JCV), Simian virus 40 (SV40), or BK Virus (BKV); influenza, Human Immunodeficiency Virus type 1 (HIV-1), Human Papilloma Virus (HPV), adenovirus, Epstein-Barr Virus (EBV), Hepatitis C Virus (HCV), Molluscum contagiosum virus (MCV); Human T- lymphotropic virus type 1 HTLV-1), Herpes Simplex Virus type 1 (HSV-1),

cytomegalovirus (CMV), hepatitis B virus, Bovine papillomavirus (BPV-1), human T-cell lymphotropic virus type 1, Japanese encephalitis virus, respiratory syncytial virus (RSV), and West Nile virus.

[00103] Further provided herein is a method for treating a parasitic infection in a patient by administering to the patient a therapeutically effective amount of a compound of formula I. Examples of parasites that may cause parasitic infections to be treated include, but are not limited to, Plasmodium and Theileria. [00104] PP2A enzymes are involved in the regulation of cell transcription, cell cycle, and viral transformation. Many viruses, including cytomegalovirus, parainfluenza, DNA tumor viruses, and HIV-1, utilize different approaches to exploit PPA2 in order to modify, control, or inactivate cellular activities of the host [Garcia et al, Microbes and Infection, 2, 2000, 401-407]. Therefore, the compounds provided herein may further be used in a method for treating a viral infection in a patient by administering to the patient a therapeutically effective amount of a compound of formula (I). Examples of viruses that may cause viral infections to be treated include, but are not limited to: a polyomavirus, such as John Cunningham Virus (JCV), Simian virus 40 (SV40), or BK Virus (BKV); influenza, Human Immunodeficiency Virus type 1 (HIV-1), Human Papilloma Virus (HPV), adenovirus, Epstein-Barr Virus (EBV), Hepatitis C Virus (HCV), Molluscum contagiosum virus (MCV); Human T-lymphotropic virus type 1 HTLV-1), Herpes Simplex Virus type 1 (HSV-1), cytomegalovirus (CMV), hepatitis B virus, Bovine papillomavirus (BPV-1), human T-cell lymphotropic virus type 1, Japanese encephalitis virus, respiratory syncytial virus (RSV), and West Nile virus.

[00105] Serine/Threonine phosphatases, including PP2A are involved in modulation of synaptic plasticity (D. G. Winder and J. D. Sweatt, Nature Reviews Neuroscience, vol 2, July 2001, pages 461 - 474). Persistently decreased PP2A activity is associated with maintenance of Long Term Potentiation (LTP) of synapses, thus treatment PP2A activators such as those described here may reverse synaptic LTP. Psychostimulant drugs of abuse such as cocaine and methamphetamine are associated with deleterious synaptic LTP (L. Mao et al, Neuron 67, September 9, 2010 and A. Stipanovich et al, Nature vol 453, 2008, pages 879 - 884), which may underlie the pathology of addiction and relapse therefore PP2A activators described here may be useful as treatments for psychostimulant abuse.

[00106] Abnormalities in synaptic structure and signaling are linked to autistic spectrum disorder, see for example, Y Chen et al, CTTNBP2, but not CTTNBP2NL, regulates dendritic spinogenesis and synaptic distribution of the striatin-PP2A complex, Molecular Biology of the Cell, 23, November 15, 2012, 4383-4392. PP2A has been shown to be important in normal development of dendritic spines, and treatment with compounds of the present invention may ameliorate or reverse autistic spectrum disorder.

[00107] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. A comprehensive list of abbreviations utilized by organic chemists (i.e. persons of ordinary skill in the art) appears in the first issue of each volume of the Journal of Organic Chemistry. The list, which is typically presented in a table entitled "Standard List of Abbreviations" is incorporated herein by reference. In the event that there is a plurality of definitions for terms cited herein, those in this section prevail unless otherwise stated.

[00108] As used herein, the terms "comprising" and "including" or grammatical variants thereof are to be taken as specifying the stated features, integers, steps or components but do not preclude the addition of one or more additional features, integers, steps, components or groups thereof. This term encompasses the terms "consisting of and "consisting essentially of.

[00109] The phrase "consisting essentially of or grammatical variants thereof when used herein are to be taken as specifying the stated features, integers, steps or components but do not preclude the addition of one or more additional features, integers, steps, components or groups thereof, but only if the additional features, integers, steps, components or groups thereof do not materially alter the basic and novel characteristics of the claimed composition or method.

[00110] A "patient," as used herein, includes both humans and other animals, particularly mammals. Thus the methods are applicable to both human therapy and veterinary applications. In some embodiments, the patient is a mammal, for example, a primate. In some embodiments, the patient is a human.

[00111] Treatment can involve administering a compound described herein to a patient diagnosed with a disease, and may involve administering the compound to a patient who does not have active symptoms. Conversely, treatment may involve administering the compositions to a patient at risk of developing a particular disease, or to a patient reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made.

[00112] The terms "administer", "administering" or "administration" in reference to a dosage form of the invention refers to the act of introducing the dosage form into the system of subject in need of treatment. When a dosage form of the invention is given in combination with one or more other active agents (in their respective dosage forms), "administration" and its variants are each understood to include concurrent and/or sequential introduction of the dosage form and the other active agents. Administration of any of the described dosage forms includes parallel administration, co-administration or sequential administration. In some situations, the therapies are administered at

approximately the same time, e.g., within about a few seconds to a few hours of one another.

[00113] A "therapeutically effective" amount of the compounds described herein is typically one which is sufficient to achieve the desired effect and may vary according to the nature and severity of the disease condition, and the potency of the compound. It will be appreciated that different concentrations may be employed for prophylaxis than for treatment of an active disease. A therapeutic benefit is achieved with the amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the patient, notwithstanding that the patient may still be afflicted with the underlying disorder.

[00114] The term "modulate" with respect to a FOXO transcription factor protein refers to activation of the FOXO transcription factor protein and its biological activities associated with the FOXO pathway. Modulation of FOXO transcription factor proteins includes up-regulation (i.e., agonizing, activation or stimulation). The mode of action of a FOXO modulator can be direct, e.g., through binding to the FOXO transcription factor protein as a ligand. The modulation can also be indirect, e.g., through binding to and/or modifying another molecule which otherwise binds to and activates the FOXO transcription factor protein.

[00115] Throughout this specification the terms and substituents retain their definitions.

[00116] Ci to C20 hydrocarbon includes alkyl, cycloalkyl, polycycloalkyl, alkenyl, alkynyl, aryl and combinations thereof. Examples include benzyl, phenethyl,

cyclohexylmethyl, adamantyl, camphoryl and naphthylethyl. Hydrocarbyl refers to any substituent comprised of hydrogen and carbon as the only elemental constituents. Aliphatic hydrocarbons are hydrocarbons that are not aromatic; they may be saturated or unsaturated, cyclic, linear or branched. Examples of aliphatic hydrocarbons include isopropyl, 2- butenyl, 2-butynyl, cyclopentyl, norbornyl, etc. Aromatic hydrocarbons include benzene (phenyl), naphthalene (naphthyl), anthracene, etc. [00117] Unless otherwise specified, alkyl (or alkylene) is intended to include linear or branched saturated hydrocarbon structures and combinations thereof. Alkyl refers to alkyl groups from 1 to 20 carbon atoms, preferably 1 to 10 carbon atoms, more preferably 1 to 6 carbon atoms. Examples of alkyl groups include methyl, ethyl, propyl, isopropyl, n-butyl, s-butyl, t-butyl and the like.

[00118] Cycloalkyl is a subset of hydrocarbon and includes cyclic hydrocarbon groups of from 3 to 8 carbon atoms. Examples of cycloalkyl groups include cy-propyl, cy-butyl, cy-pentyl, norbornyl and the like.

[00119] Unless otherwise specified, the term "carbocycle" is intended to include ring systems in which the ring atoms are all carbon but of any oxidation state. Thus (C3-C10) carbocycle refers to both non-aromatic and aromatic systems, including such systems as cyclopropane, benzene and cyclohexene; (C ₈ -C ₁₂ ) carbopolycycle refers to such systems as norbornane, decalin, indane and naphthalene. Carbocycle, if not otherwise limited, refers to monocycles, bicycles and polycycles.

[00120] Heterocycle means an aliphatic or aromatic carbocycle residue in which from one to four carbons is replaced by a heteroatom selected from the group consisting of N, O, and S. The nitrogen and sulfur heteroatoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. Unless otherwise specified, a heterocycle may be non-aromatic (heteroaliphatic) or aromatic (heteroaryl). Examples of heterocycles include pyrrolidine, pyrazole, pyrrole, indole, quinoline, isoquinoline,

tetrahydroisoquinoline, benzofuran, benzodioxan, benzodioxole (commonly referred to as methylenedioxyphenyl, when occurring as a substituent), tetrazole, morpholine, thiazole, pyridine, pyridazine, pyrimidine, thiophene, furan, oxazole, oxazoline, isoxazole, dioxane, tetrahydrofuran and the like. Examples of heterocyclyl residues include piperazinyl, piperidinyl, pyrazolidinyl, imidazolyl, imidazolinyl, imidazolidinyl, pyrazinyl,

oxazolidinyl, isoxazolidinyl, thiazolidinyl, isothiazolyl, quinuclidinyl, isothiazolidinyl, benzimidazolyl, thiadiazolyl, benzopyranyl, benzothiazolyl, tetrahydrofuryl,

tetrahydropyranyl, thienyl (also historically called thiophenyl), benzothienyl,

thiamorpholinyl, oxadiazolyl, triazolyl and tetrahydroquinolinyl.

[00121] Alkoxy or alkoxyl refers to groups of from 1 to 20 carbon atoms, preferably 1 to 10 carbon atoms, more preferably 1 to 6 carbon atoms of a straight or branched configuration attached to the parent structure through an oxygen. Examples include methoxy, ethoxy, propoxy, isopropoxy and the like. Lower-alkoxy refers to groups containing one to four carbons. For the purpose of this application, alkoxy and lower alkoxy include methylenedioxy and ethylenedioxy.

[00122] The term "halogen" means fluorine, chlorine, bromine or iodine atoms. In one embodiment, halogen may be a fluorine or chlorine atom.

[00123] Unless otherwise specified, acyl refers to formyl and to groups of 1, 2, 3, 4, 5, 6, 7 and 8 carbon atoms of a straight, branched, cyclic configuration, saturated, unsaturated and aromatic and combinations thereof, attached to the parent structure through a carbonyl functionality. Examples include acetyl, benzoyl, propionyl, isobutyryl and the like.

Lower-acyl refers to groups containing one to four carbons. The double bonded oxygen, when referred to as a substituent itself is called "oxo".

[00124] As used herein, the term "optionally substituted" may be used interchangeably with "unsubstituted or substituted". The term "substituted" refers to the replacement of one or more hydrogen atoms in a specified group with a specified radical. For example, substituted alkyl, aryl, cycloalkyl, heterocyclyl etc. refer to alkyl, aryl, cycloalkyl, or heterocyclyl wherein one or more H atoms in each residue are replaced with halogen, haloalkyl, alkyl, acyl, alkoxyalkyl, hydroxy lower alkyl, carbonyl, phenyl, heteroaryl, benzenesulfonyl, hydroxy, lower alkoxy, haloalkoxy, oxaalkyl, carboxy, alkoxycarbonyl [- C(=0)0-alkyl], alkoxycarbonylamino [ FINC(=0)0-alkyl], aminocarbonyl (also known as carboxamido) [-C(=0)NH ₂ ], alkylaminocarbonyl [-C(=0) H-alkyl], cyano, acetoxy, nitro, amino, alkylamino, dialkylamino, (alkyl)(aryl)aminoalkyl, alkylaminoalkyl (including cycloalkylaminoalkyl), dialkylaminoalkyl, dialkylaminoalkoxy, heterocyclylalkoxy, mercapto, alkylthio, sulfoxide, sulfone, sulfonylamino, alkylsulfinyl, alkylsulfonyl, acylaminoalkyl, acylaminoalkoxy, acylamino, amidino, aryl, benzyl, heterocyclyl, heterocyclylalkyl, phenoxy, benzyloxy, heteroaryloxy, hydroxyimino, alkoxyimino, oxaalkyl, amino sulfonyl, trityl, amidino, guanidino, ureido, benzyloxyphenyl, and benzyloxy. "Oxo" is also included among the substituents referred to in "optionally substituted"; it will be appreciated by persons of skill in the art that, because oxo is a divalent radical, there are circumstances in which it will not be appropriate as a substituent (e.g. on phenyl). In one embodiment, 1, 2, or 3 hydrogen atoms are replaced with a specified radical. In the case of alkyl and cycloalkyl, more than three hydrogen atoms can be replaced by fluorine; indeed, all available hydrogen atoms could be replaced by fluorine. In preferred embodiments, substituents are halogen, haloalkyl, alkyl, acyl, hydroxyalkyl, hydroxy, alkoxy, haloalkoxy, aminocarbonyl oxaalkyl, carboxy, cyano, acetoxy, nitro, amino, alkylamino, dialkylamino, alkylthio, alkylsulfinyl, alkylsulfonyl,

alkylsulfonylamino arylsulfonyl, arylsulfonylamino, and benzyloxy.

[00125] Substituents R ⁿ are generally defined when introduced and retain that definition throughout the specification and in all independent claims.

Examples

[00126] Preparation of compounds can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. Suitable groups for that purpose are discussed in standard textbooks in the field of chemistry, such as Protective Groups in Organic Synthesis by T.W.Greene and P.G.M.Wuts [John Wiley & Sons, New York, 1999], in Protecting Group Chemistry, 1 ^st Ed., Oxford University Press, 2000; and in March 's Advanced Organic chemistry: Reactions, Mechanisms, and Structure, 5 ^th Ed., Wiley-Interscience Publication, 2001.

[00127] Many compounds of formula I may be prepared by the schemes shown in U.S. Provisional Application US 62/201,819, which is incorporated herein by reference. In general, compounds of formula I can be prepared by: reacting a compound of formula XII

with a compound of formula XIII wherein R is (Ci-C4)alkyl, in the presence of a palladium catalyst to provide a product of formula XIV

and

oxidizing the product of formula XIV with osmium tetroxide to provide the cis diol XV or with meta chloroperbenzoic acid followed by hydrolysis of the resulting epoxide to provide the trans diol XVI:

XV XVI [00128] If a chiral palladium catalyst is used in the initial step to make XIV, the stereochemistry can thus be controlled for all products downstream.

[00129] The diol of formula XV/XVI

XV/XVI

may be reacted with thionyl chloride or a sulfonyl chloride, such as methanesulfonyl chloride, to provide a sulfonylated product; and the sulfonylated product may be reacted with an alkali metal azide to provide a 3-azido-4-hydroxy-5-aminoheterocycle of formula XVII:

XVII

The azide may be reduced to provide the corresponding amine XVIII:

XVIII A convenient reducing agent is triphenyl phosphine, but there are many procedures known to persons of skill that may be employed for reducing an azide to an amine. The amine XVIII may be reacted with the appropriate sulfonyl chloride to provide the products described herein in which Y is OH and Q is oxygen. When Q is NR, the compounds may be made in the same fashion as above but with R initially being a protecting group, such as t-Boc or Cbz. The protecting group is then cleaved after synthesis is complete, and the resulting NH condensed with any acylating or alkylating agent needed by procedures well- known in the art. Introduction of aryl or heteroaryl moieties onto the ring nitrogen may be achieved by SNAT substitution reactions for electron deficient aromatic systems such 4- nitrophenyl or electrophilic heteroaromatic systems such as 4-pyrimidinyl systems. More generally arylation or heteroarylation of the ring nitrogen may be achieved by palladium mediated N-aryl amination: the Buchwald-Hartwig reaction, see for example N. Marion et al, in "Modified (NHC)Pd(allyl)Cl (NHC ) N-Heterocyclic Carbene) Complexes for Room- Temperature Suzuki-Miyaura and Buchwald-Hartwig Reactions" J. Am. Chem. Soc. 2006, 128, 4101 or J. P. Wolfe et al in "Rational Development of Practical Catalysts for Aromatic Carbon-Nitrogen Bond Formation. Examples as applied to compounds of the present invention are shown in the scheme below:

When Q is sulfur, the ring will either start out in the sulfone oxidation state or it will be oxidized to the sulfone when dihydroxylating the allylic olefin. When compounds in which Y is hydrogen are desired, the olefin XIV may be treated with a sterically hindered hydroborating agent such as 9-BBN or the like, followed by oxidation of the alkyboron to the alcohol with an oxidant such as N-methylmorpholine-N-oxide or aqueous hydrogen peroxide. The alchol intermediate is converted to leaving group such as the mesylate and displaced with azide. This is carried forward to the target compound by reduction and reaction with the appropriate aryl sulfonyl chloride. This process is illustrated in the scheme below:

Alternatively compounds in which Y = H maybe accessed via radical mediated

deoxgenation processes as described in, for example, W. Hartwig in "Modern Methods For The Radical Deoxgenation of Alcohols", Tetrahedron Vol. 39, No. 16, page 2609 (1983). One example of this type of transformation as applied to compounds of the present invention (Barton-McCombie conditions) is shown below:

[00207] To a solution of tert-butyl 5-hydroxy-5,6-dihydropyridine-l(2H)-carboxylate

(10.0 g, 50.1 mmol) in THF (160 mL) was added «-butyllithium (2.5 M in hexanes, 19.8 mL, 2.50 mmol) at -78 °C. The resulting solution was warmed to 0 °C and stirred for 5 min prior to addition of di-tert-butyl dicarbonate (12.0 g, 55.1 mmol) in THF (80.0 mL). The reaction was warmed to RT, stirred for 16 h. The reaction was then quenched with water, extracted with ethyl acetate, washed with brine, concentrated, and the residue purified by flash chromatography (S1O2, 0%-3% ethyl acetate-hexanes) to afford slightly crude tert- butyl 5-((tert-butoxycarbonyl)oxy)-5,6-dihydropyridine-l(2H)-carbo xylate (15.3 g) as a colorless oil which was taken to the next step without further purification. This material serves as the alkylating agent in the first step of Scheme 6.

[00208] A Pd mediated alkylation may be carried out as follows: a 350 mL glass ^® pressure vessel was charged with Pd ₂ .dba . CHC1 (1.11 g, 1.07 mmol, 5 mol%), and triphenylphosphine (0.841 g, 3.21 mmol, 15 mol%). The vessel is sealed, evacuated and backfilled with argon three times. Dry degassed dichloromethane (60.0 mL) is added, and the mixture is stirred at room temperature for 60 min. Racemic tert-butyl cyclohex-2-en-l- yl carbonate (15.3 g, 51.1 mmol) is added followed by bis(4-(trifluoromethyl)phenyl)amine (21.4 mmol) in dry degassed dichloromethane. The reaction mixture is sealed and stirred at room temperature for one to ten days. At this point, the reaction mixture is evaporated onto silica gel and subjected to column chromatography on silica gel eluting with ethyl acetate- hexane to afford tert-butyl 3-(bis(4-(trifluoromethyl)phenyl)amino)-3,6-dihydropyridine- l(2H)-carboxylate which is taken to the next step without purification. Use of chiral bisphosphine ligands such as DACH-phenyl Trost ligand will yield enantiomerically enriched material.

[00209] Jert-butyl 3-(bis(4-(trifluoromethyl)phenyl)amino)-3,6-dihydropyridine- l(2H)-carboxylate obtained in the above process (or by other routes) is carried forward using the steps shown in Scheme 6, using conditions analogous to those described for Scheme 1. Boc-protected Example 21 may be deprotected using trifluoroacetic acid in methylenechloride to give Example 22, which is then further elaborated to give Example 23 or related compounds.

[00210] Alternate Epoxidation Route

Scheme 7

[00211] An alternative route to compounds of the present invention is outlined in Scheme 7 in which a cyclic or heterocyclic allylic carbonate is first reacted with a protected aryl sulfonamide in the presence of a palladium catalyst. This may be carried out with control of the newly formed chiral center by using a chiral ligand such as the Trost-DACH bisphosphine. Thus reagents of type (i) are reacted with an optionally protected arylsulfonamide(ii), for example 4-trifluoromethoxybenzene sulfonamide in the presence of a chiral palladium catalyst to give enantiomerically enriched allylarylsulfonamides of type (iii). Protecting groups, Pg, include but are not limited to, benzyl(Bn) and substituted benzyl groups or alkoxycarbonyl groups such as Boc or Cbz. The protected allylic sulfonamides (iii) may be epoxidized in a non-diastereoselective fashion to give a diasteromeric mixture of epoxides, (iv), which are separated by chromatographic techniques; or alternatively steroselective expoxidation will give access to one

diastereoisomer preferentially. Epoxidation reagents include peroxoic acids such as mCPBA, dioxiranes such as dimethyldioxirane, oxaziridines such as 3-phenyl-2-tosyl-l,2- oxaziridine or hydroperoxides such as t-butylhydroperoxide with transition metal ion catalysis. Either isomer of compound (iv) is converted to PP2A activators of the present invention by treatment with an optionally substituted diaryl amine in the presence of a base such as sodium amide, sodium hydride or potassium t-butoxide in an aprotic solvent.

Protecting groups are removed by, for example hydrogenolysis where Pg = benzyl, or other condition appropriate for the original choice of protecting groups. Alternatively the diastereomeric mixture of (iv) may be carried forward and isomers separated at the penultimate benzyl protected stage or the final deprotected products.

[00212] A specific example of this process is shown in Scheme 8:

Cell viability assays (IC50 determination)

[00215] Cell viability assays were performed according to Denizot, F. and R. Lang, Journal of Immunological Methods, 1986. 89(22): p. 271 - 277. H1650 lung cancer cells were plated at 150,000 cells per well in a 12 well plate. Twenty-four hours after plating, cells were treated as described with increasing concentrations of drug and control. Forty- eight hours after drug treatment, cells were treated with 100 μΕ of 3-(4,5-Dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) and incubated for 2 hours at 37 C. The MTT solution was subsequently replaced with 300 μΕ of n-propyl alcohol and re-aliquoted to a 96 well plate. Spectrophotometric analysis of each solution was performed using a 96 well plate reader at 600 nm in triplicate. Results are shown in Table 1 : [00216] Table 1. Cell Viability Data

Colony Formation Assay

[00217] Protocol for clonogenic assay follows Sangodkar et al, J Clin Invest

2012;122:2637-51.

[00218] Cell culture and staining: For both A5491uc and HI 650 cells, 500 cells are seeded into each well of a 6-well plate and allowed to attach for 24 hours before drug treatment. The following day, cells are treated with either the appropriate dose of drug or an equivalent volume of DMSO (two replicates are treated for each condition). For each condition, depleted media is replaced with fresh media containing the equivalent drug dose four days after initial treatment. Cells are harvested either 7 (A5491uc) or 8 (HI 650) days after initial treatment. Briefly, medium is aspirated from each well and the cells are washed twice with ice-cold PBS, then plates are allowed to dry at room temperature for 4 hours. Cells are fixed for one hour in a fixing solution consisting of 10% methanol and 10% glacial acetic acid in distilled water, then stained overnight in 1% (w/v) crystal violet dissolved in methanol. The next day, staining solution is aspirated from the wells and plates are washed gently with distilled water to remove excess stain before colony counting. Colonies are imaged on a ChemiDoc XRS+ (Bio-Rad) and images are exported as 8-bit TIFF files. Colonies are counted using the Colony Counter plugin in ImageJ, with colony size defined as between 4 and 400 square pixels, and minimum circularity set at 0.6.

Duplicate wells are averaged to obtain a single value for each condition. Results (number of colonies) for A5491uc cells and results (number of colonies) for H1650 cells may be analyzed separately.

In vivo cancer model

[00219] To assess the in vivo effects of the compounds, subcutaneous xenograft of lung cancer cell line H441 is generated. Cells (5 ^χ 10 ⁶ ) are injected into the right flank of 6- to 8-week-old male BALB/c nu/nu mice (Charles River, Wilmington, MA). Tumor volume is assessed twice a week by caliper measurement. Mice are randomized to treatment groups based on initial tumor volume average of 100mm ³ per group. Mice are dosed by oral gavage with, for example, 15 mg/kg QD, 15 mg/kg BID, 50 mg/kg QD, or 50 mg/kg BID. Mouse tumors are measured twice a week for the duration of the study. Mouse body weights are recorded weekly and percentage of mice body weights during treatment is calculated as: weight at each time point/initial weight xlOO. Animals are observed for signs of toxicity (mucous diarrhea, abdominal stiffness and weight loss). Mice undergo treatment for 30 days and are sacrificed 2 hours after the last dose. Tumors are then excised and cut for both formalin-fixation and snap frozen in liquid nitrogen.
