<u>STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH</u>

0002This invention was made with government support under CA164331 and CA12861, awarded by the National Institutes of Health. This work was supported by the U.S. Department of Veterans Affairs. The Government has certain rights in the invention.

<u>BACKGROUND OF THE INVENTION</u>

0003Prostate cancer is the most common cancer and the second leading cause of cancer death in Western men. When the cancer is confined locally, the disease can usually be treated by surgery or radiation. However, 30% of prostate cancers treated that way relapse with distant metastatic disease, and some patients have advanced disease at diagnosis. Advanced disease is treated by castration and/or administration of anti androgens, the so-called androgen deprivation therapy. Castration lowers the circulating levels of androgens and reduces the activity of androgen receptor (AR). Administration of antiandrogens blocks AR function by competing away androgen binding, thereby reducing the AR activity. Although initially effective, these treatments quickly fail and the cancer becomes hormone refractory, or castration resistant.

0004Castration resistant prostate cancer (CRPC) is typified by persistent expression and transcriptional activity of the androgen receptor (AR). Over the last decade, pre-clinical models, correlative studies involving patient material, and clinical studies have provided the evidence to support the notion that inhibiting the AR represents a viable approach to effectively treat CRPC. Accordingly, improved inhibitors of the AR are needed.

A) Physiologic regulation of androgen synthesis. Pulsatile secretion of LHRH induces luteinizing hormone (LH) secretion by the anterior pituitary, which in turn drives testosterone (T) synthesis and secretion by the testes, from which 90-95% of androgens are derived. LHRH analogues, by providing continuous, unremitting engagement of the LHRH receptors on the anterior pituitary, suppress LH secretion. The adrenal glands are a minor source of androgens; adrenal androgens (e.g. DHEA) are converted into T or dihydrotestosterone (DHT) in peripheral tissues. B) AR working mechanism. Upon ligand binding, AR dimerizes, translocates to the nucleus, and induces gene transcription. Novel AR targeting agents (in red), inhibit intratumoral steroidogenesis (e.g., abiraterone, a 17α-hydroxylase inhibitor) or function as pure AR antagonists (e.g., MDV3100). C) Schematic of full-length AR (AR^FL), the constitutively active ARΔLBD, and a Y1H system that can serve as the basis for a high-throughput screening assay.

Discussion

0083The present disclosure describes compounds that inhibit the AR in novel ways. In mammalian cell systems, the compounds of Formulas I, II, III, IV, V, VI, VII or VIII inhibit ligand-induced and constitutive AR transcriptional activity, and enhance AR degradation. The activity of endogenously and ectopically expressed wild-type and splice variant ARs is inhibited by JN018 over a wide range of concentrations and in a dose-dependent fashion. Importantly, JN018 does not inhibit the transcriptional activity of the closely related glucocorticoid receptor (GR). Domain swapping experiments revealed that JN018 inhibits the transactivation domain (TAD) of the AR. JN018 reduces the expression of AR target genes, including TMPRSS and NDRG. JN018 inhibited the growth of AR expressing prostate cancer cells in a dose-dependent fashion, but had no effect on AR null models. Mechanistic studies establish that JN018 targets the AR and its splice variants for degradation.

0084The compounds disclosed herein target the AR N-terminal TAD. These compounds, such as JN018, can be used to treat diseases, the growth of which is driven by the AR or its splice variants. Prostate cancer is an example of one such disease. These compounds offer competitive advantages over existing, approved compounds that target the AR because existing compounds target the LBD of the AR, whereas JN018 and are active against full length and constitutively active AR variants that lack a functional LBD (see below, section 6 for more details). JN018 targets the AR N-terminus and inhibits the activity of constitutively active AR variants that lack a functional LBD (see below, section 6 for more details). These AR variants have been shown to confer resistance to currently approved AR targeting agents. In addition, JN018 induces degradation of the AR including AR splice variants, which is not a known mechanism of any AR targeting agent that has received regulatory approval. These AR variants have been shown to confer resistance to current AR targeting agents.

Compositions and Modes of Administration

0085The compounds of this invention may be used in treating the conditions described herein, in the form of the free base, salts (preferably pharmaceutically acceptable salts), solvates, hydrates, prodrugs, isomers, or mixtures thereof. All forms are within the scope of the disclosure. Acid addition salts may be formed and provide a more convenient form for use; in practice, use of the salt form inherently amounts to use of the base form. The acids which can be used to prepare the acid addition salts include preferably those which produce, when combined with the free base, pharmaceutically acceptable salts, that is, salts whose anions are non-toxic to the subject organism in pharmaceutical doses of the salts, so that the beneficial properties inherent in the free base are not vitiated by side effects ascribable to the anions. Although pharmaceutically acceptable salts of the basic compounds are preferred, all acid addition salts are useful as sources of the free base form even if the particular salt per se is desired only as an intermediate product as, for example, when the salt is formed only for the purposes of purification and identification, or when it is used as an intermediate in preparing a pharmaceutically acceptable salt by ion exchange procedures.

0086Pharmaceutically acceptable salts within the scope of the disclosure include those derived from the following acids; mineral acids such as hydrochloric acid, sulfuric acid, phosphoric acid and sulfamic acid; and organic acids such as acetic acid, citric acid, lactic acid, tartaric acid, malonic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamic acid, quinic acid, and the like.

0087The compounds of the present invention can be formulated as pharmaceutical compositions and administered to a subject in need of treatment, for example a mammal, such as a human patient, in a variety of forms adapted to the chosen route of administration, for example, orally, nasally, intraperitoneally, or parenterally (e.g., by intravenous, intraperitoneal, subcutaneous, intramuscular, transepithelial, nasal, intrapulmonary, intrathecal, rectal or topical routes). Parenteral administration may be by continuous infusion over a selected period of time.

0088In accordance with the methods of the disclosure, the described compounds may be administered to a patient in a variety of forms depending on the selected route of administration, as will be understood by those skilled in the art. The compositions containing the compounds of the disclosure can be prepared by known methods for the preparation of pharmaceutically acceptable compositions which can be administered to subjects, such that an effective quantity of the active substance is combined in a mixture with a pharmaceutically acceptable vehicle. Suitable vehicles are described, for example, in Remington's Pharmaceutical Sciences (<nplcit id="ncit0001" npl-type="b"><text>Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pa., USA 1985</text></nplcit>). On this basis, the compositions include, albeit not exclusively, solutions of the substances in association with one or more pharmaceutically acceptable vehicles or diluents, and contained in buffered solutions with a suitable pH and iso-osmotic with the physiological fluids.

0089A composition comprising a compound of the present disclosure may also contain adjuvants, such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption, such as aluminum monostearate and gelatin.

0090A person skilled in the art would know how to prepare suitable formulations. Conventional procedures and ingredients for the selection and preparation of suitable formulations are described, for example, in <nplcit id="ncit0002" npl-type="b"><text>Remington's Pharmaceutical Sciences (1990 - 18th editi</text></nplcit>on) and in <nplcit id="ncit0003" npl-type="s"><text>The United States Pharmacopeia: The National Formulary (USP 24 NF19) published in 1999</text></nplcit>.

0091Thus, compounds of the invention may be systemically administered, e.g., orally, in combination with a pharmaceutically acceptable vehicle such as an inert diluent or an assimilable edible carrier; or by inhalation or insufflation. They may be enclosed in hard or soft shell gelatin capsules, may be compressed into tablets, or may be incorporated directly with the food of the patient's diet. For oral therapeutic administration, the compounds may be combined with one or more excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. The compounds may be combined with a fine inert powdered carrier and inhaled by the subject or insufflated. Such compositions and preparations should contain at least 0.1% of compounds of formulas I, II, III, IV, V, VI, VII or VIII. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2% to about 60% of the weight of a given unit dosage form. The amount of the compounds in such therapeutically useful compositions is such that an effective dosage level will be obtained.

0092In certain embodiments of the disclosure, compositions comprising a compound of the present disclosure for oral administration include capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or a suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and the like, each containing a predetermined amount of the compound of the present disclosure as an active ingredient.

0093In solid dosage forms for oral administration (capsules, tablets, troches, pills, dragees, powders, granules, and the like), one or more compositions comprising the compound of the present disclosure may be mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose, gum tragacanth, corn starch, and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, cetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like. Various other materials may be present as coatings or to otherwise modify the physical form of the solid unit dosage form. For instance, tablets, pills, or capsules may be coated with gelatin, wax, shellac or sugar and the like. A syrup or elixir may contain the active compound, sucrose or fructose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. Any material used in preparing any unit dosage form should be pharmaceutically acceptable and substantially non-toxic in the amounts employed. In addition, the compounds may be incorporated into sustained-release preparations and devices. For example, the compounds may be incorporated into time release capsules, time release tablets, and time release pills.

0094Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the compound of the present disclosure, the liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol (ethanol), isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming, and preservative agents.

0095Suspensions, in addition to the active compounds, salts and/or prodrugs thereof, may contain suspending agents such as ethoxylated isostearyl alcohols, polyoxyethylene sorbitol, and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

0096In certain embodiments, pharmaceutical compositions suitable for parenteral administration may comprise the compound of the present disclosure in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents. Examples of suitable aqueous and non-aqueous carriers which may be employed in the pharmaceutical compositions of the disclosure include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

0097The compounds may be administered intravenously or intraperitoneally by infusion or injection. Solutions of the compounds or their salts can be prepared in water, optionally mixed with a nontoxic surfactant. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, triacetin, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations can contain a preservative to prevent the growth of microorganisms.

0098The pharmaceutical dosage forms suitable for injection or infusion can include sterile aqueous solutions or dispersions or sterile powders comprising the compounds which are adapted for the extemporaneous preparation of sterile injectable or infusible solutions or dispersions, optionally encapsulated in liposomes. In all cases, the ultimate dosage form should be sterile, fluid and stable under the conditions of manufacture and storage. The liquid carrier or vehicle can be a solvent or liquid dispersion medium comprising, for example, water, ethanol, a polyol (for example, glycerol, propylene glycol, liquid polyethylene glycols, and the like), vegetable oils, nontoxic glyceryl esters, and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the formation of liposomes, by the maintenance of the required particle size in the case of dispersions or by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, buffers or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.

0099Sterile injectable solutions are prepared by incorporating the compounds in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filter sterilization. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze drying techniques, which yield a powder of the active ingredient plus any additional desired ingredient present in the previously sterile-filtered solutions.

0100For topical administration, the compounds may be applied in pure form. However, it will generally be desirable to administer them to the skin as compositions or formulations, in combination with a dermatologically acceptable carrier, which may be a solid or a liquid.

0101Useful solid carriers include finely divided solids such as talc, clay, microcrystalline cellulose, silica, alumina and the like. Other solid carriers include nontoxic polymeric nanoparticles or microparticles. Useful liquid carriers include water, alcohols or glycols or water/alcohol/glycol blends, in which the compounds can be dissolved or dispersed at effective levels, optionally with the aid of non-toxic surfactants. Adjuvants such as fragrances and additional antimicrobial agents can be added to optimize the properties for a given use. The resultant liquid compositions can be applied from absorbent pads, used to impregnate bandages and other dressings, or sprayed onto the affected area using pump-type or aerosol sprayers.

0102Thickeners such as synthetic polymers, fatty acids, fatty acid salts and esters, fatty alcohols, modified celluloses or modified mineral materials can also be employed with liquid carriers to form spreadable pastes, gels, ointments, soaps, and the like, for application directly to the skin of the user.

0103Examples of useful dermatological compositions which can be used to deliver the compounds to the skin are known to the art; for example, see <patcit id="pcit0003" dnum="US4608392A"><text>Jacquet et al. (U.S. Pat. No. 4,608,392</text></patcit>), <patcit id="pcit0004" dnum="US4992478A"><text>Geria (U.S. Pat. No. 4,992,478</text></patcit>), <patcit id="pcit0005" dnum="US4559157A"><text>Smith et al. (U.S. Pat. No. 4,559,157</text></patcit>) and <patcit id="pcit0006" dnum="US4820508A"><text>Wortzman (U.S. Pat. No. 4,820,508</text></patcit>), all of which are hereby incorporated by reference.

0104Useful dosages of the compounds of formulas I, II, III, IV, V, VI, VII or VIII can be determined by comparing their in vitro activity, and in vivo activity in animal models. Methods for the extrapolation of effective dosages in mice, and other animals, to humans are known to the art; for example, see <patcit id="pcit0007" dnum="US4938949A"><text>U.S. Pat. No. 4,938,949</text></patcit>, which is hereby incorporated by reference.

0105For example, the concentration of the compounds in a liquid composition, such as a lotion, can be from about 0.1-25% by weight, or from about 0.5-10% by weight. The concentration in a semi-solid or solid composition such as a gel or a powder can be about 0.1-5% by weight, or about 0.5-2.5% by weight.

0106The amount of the compounds required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the patient and will be ultimately at the discretion of the attendant physician or clinician.

0107Effective dosages and routes of administration of agents of the invention are conventional. The exact amount (effective dose) of the agent will vary from subject to subject, depending on, for example, the species, age, weight and general or clinical condition of the subject, the severity or mechanism of any disorder being treated, the particular agent or vehicle used, the method and scheduling of administration, and the like. A therapeutically effective dose can be determined empirically, by conventional procedures known to those of skill in the art. See, e.g., <nplcit id="ncit0004" npl-type="b"><text>The Pharmacological Basis of Therapeutics, Goodman and Gilman, eds., Macmillan Publishing Co., New York</text></nplcit>. For example, an effective dose can be estimated initially either in cell culture assays or in suitable animal models. The animal model may also be used to determine the appropriate concentration ranges and routes of administration. Such information can then be used to determine useful doses and routes for administration in humans. A therapeutic dose can also be selected by analogy to dosages for comparable therapeutic agents.

0108The particular mode of administration and the dosage regimen will be selected by the attending clinician, taking into account the particulars of the case (e.g., the subject, the disease, the disease state involved, and whether the treatment is prophylactic). Treatment may involve daily or multi-daily doses of compound(s) over a period of a few days to months, or even years.

0109In general, however, a suitable dose will be in the range of from about 0.001 to about 100 mg/kg, e.g., from about 0.01 to about 100 mg/kg of body weight per day, such as above about 0.1 mg per kilogram, or in a range of from about 1 to about 10 mg per kilogram body weight of the recipient per day. For example, a suitable dose may be about 1 mg/kg, 10 mg/kg, or 50 mg/kg of body weight per day.

0110The compounds of formulas I, II, III, IV, V, VI, VII or VIII are conveniently administered in unit dosage form; for example, containing 0.05 to 10000 mg, 0.5 to 10000 mg, 5 to 1000 mg, or about 100 mg of active ingredient per unit dosage form.

0111The compounds can be administered to achieve peak plasma concentrations of, for example, from about 0.5 to about 75 µM, about 1 to 50 µM, about 2 to about 30 µM, or about 5 to about 25 µM. Exemplary desirable plasma concentrations include at least or no more than 0.25, 0.5, 1, 5, 10, 25, 50, 75, 100 or 200 µM. For example, plasma levels may be from about 1 to 100 micromolar or from about 10 to about 25 micromolar. This may be achieved, for example, by the intravenous injection of a 0.05 to 5% solution of the compounds, optionally in saline, or orally administered as a bolus containing about 1-100 mg of the compounds. Desirable blood levels may be maintained by continuous infusion to provide about 0.00005-5 mg per kg body weight per hour, for example at least or no more than 0.00005, 0.0005, 0.005, 0.05, 0.5, or 5 mg/kg/hr. Alternatively, such levels can be obtained by intermittent infusions containing about 0.0002-20 mg per kg body weight, for example, at least or no more than 0.0002, 0.002, 0.02, 0.2, 2, 20, or 50 mg of the compounds per kg of body weight.

0112The compounds may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations; such as multiple inhalations from an insufflator.

0113The dosage of the compounds and/or compositions of the disclosure can vary depending on many factors such as the pharmacodynamic properties of the compound, the mode of administration, the age, health and weight of the recipient, the nature and extent of the symptoms, the frequency of the treatment and the type of concurrent treatment, if any, and the clearance rate of the compound in the subj ect to be treated. One of skill in the art can determine the appropriate dosage based on the above factors. The compounds of the disclosure may be administered initially in a suitable dosage that may be adjusted as required, depending on the clinical response. To calculate the human equivalent dose (HED) from a dosage used in the treatment of age-dependent cognitive impairment in rats, the formula HED (mg/kg) = rat dose (mg/kg) × 0.16 may be employed (see Estimating the Safe Starting Dose in Clinical Trials for Therapeutics in Adult Healthy Volunteers, December 2002, Center for Biologics Evaluation and Research). For example, using that formula, a dosage of 10 mg/kg in rats is equivalent to 1.6 mg/kg in humans. This conversion is based on a more general formula HED = animal dose in mg/kg × (animal weight in kg/human weight in kg) 0.33. Similarly, to calculate the HED from a dosage used in the treatment in mouse, the formula HED (mg/kg) = mouse dose (mg/kg) × 0.08 may be employed (see Estimating the Safe Starting Dose in Clinical Trials for Therapeutics in Adult Healthy Volunteers, December 2002, Center for Biologics Evaluation and Research).

0114The compounds and/or compositions of the disclosure can be used alone or conjointly with other therapeutic agents, or in combination with other types of treatment for treating cell proliferative disorders such as prostate cancer. For example, in some embodiments, the compounds and compositions of the disclosure can be used for treating CRPC or for treating cancers that are resistant to antiandrogen therapies such as enzalutamide, bicalutamide, abiraterone, flutamide, or nilutamide. For example, these other therapeutically useful agents may be administered in a single formulation, simultaneously or sequentially with the compound of the present disclosure according to the methods of the disclosure.

0115A number of the above-identified compounds exhibit little or no agonistic activities with respect to hormone refractory prostate cancer cells. Because these compounds are strong AR inhibitors, they can be used not only in treating prostate cancer, but also in treating other AR related diseases or conditions such as benign prostate hyperplasia, hair loss, and acne. Because AR belongs to the family of nuclear receptors, these compounds may serve as scaffolds for drug synthesis targeting other nuclear receptors, such as estrogen receptor and peroxisome proliferator-activated receptor. Therefore, they may be further developed for other diseases such as breast cancer, ovarian cancer, diabetes, cardiac diseases, and metabolism related diseases, in which nuclear receptors play a role.

0118Chemistry terms used herein are used according to conventional usage in the art, as exemplified by "<nplcit id="ncit0010" npl-type="b"><text>The McGraw-Hill Dictionary of Chemical Terms", Parker S., Ed., McGraw-Hill, San Francisco, C.A. (1985</text></nplcit>).

0119All of the above, and any other publications, patents and published patent applications referred to in this application are specifically incorporated by reference herein. In case of conflict, the present specification, including its specific definitions, will control.

0120The term "agent" is used herein to denote a chemical compound (such as an organic or inorganic compound, a mixture of chemical compounds), a biological macromolecule (such as a nucleic acid, an antibody, including parts thereof as well as humanized, chimeric and human antibodies and monoclonal antibodies, a protein or portion thereof, e.g., a peptide, a lipid, a carbohydrate), or an extract made from biological materials such as bacteria, plants, fungi, or animal (particularly mammalian) cells or tissues. Agents include, for example, agents whose structure is known, and those whose structure is not known. The ability of such agents to inhibit AR or promote AR degradation may render them suitable as "therapeutic agents" in the methods and compositions of this disclosure.

0121A "patient," "subject," or "individual" are used interchangeably and refer to either a human or a non-human animal. These terms include mammals, such as humans, primates, livestock animals (including bovines, porcines, etc.), companion animals (e.g., canines, felines, etc.) and rodents (e.g., mice and rats). "Treating" a condition or patient refers to taking steps to obtain beneficial or desired results, including clinical results. As used herein, and as well understood in the art, "treatment" is an approach for obtaining beneficial or desired results, including clinical results. Beneficial or desired clinical results can include, but are not limited to, alleviation or amelioration of one or more symptoms or conditions, diminishment of extent of disease, stabilized (i.e. not worsening) state of disease, preventing spread of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, and remission (whether partial or total), whether detectable or undetectable. "Treatment" can also mean prolonging survival as compared to expected survival if not receiving treatment.

0122The term "preventing" is art-recognized, and when used in relation to a condition, such as a local recurrence (e.g., pain), a disease such as cancer, a syndrome complex such as heart failure or any other medical condition, is well understood in the art, and includes administration of a composition which reduces the frequency of, or delays the onset of, symptoms of a medical condition in a subject relative to a subject which does not receive the composition. Thus, prevention of cancer includes, for example, reducing the number of detectable cancerous growths in a population of patients receiving a prophylactic treatment relative to an untreated control population, and/or delaying the appearance of detectable cancerous growths in a treated population versus an untreated control population, e.g., by a statistically and/or clinically significant amount.

0123"Administering" or "administration of" a substance, a compound or an agent to a subject can be carried out using one of a variety of methods known to those skilled in the art. For example, a compound or an agent can be administered, intravenously, arterially, intradermally, intramuscularly, intraperitoneally, subcutaneously, ocularly, sublingually, orally (by ingestion), intranasally (by inhalation), intraspinally, intracerebrally, and transdermally (by absorption, e.g., through a skin duct). A compound or agent can also appropriately be introduced by rechargeable or biodegradable polymeric devices or other devices, e.g., patches and pumps, or formulations, which provide for the extended, slow or controlled release of the compound or agent. Administering can also be performed, for example, once, a plurality of times, and/or over one or more extended periods.

0124Appropriate methods of administering a substance, a compound or an agent to a subject will also depend, for example, on the age and/or the physical condition of the subject and the chemical and biological properties of the compound or agent (e.g. solubility, digestibility, bioavailability, stability and toxicity). In some embodiments, a compound or an agent is administered orally, e.g., to a subject by ingestion. In some embodiments, the orally administered compound or agent is in an extended release or slow release formulation, or administered using a device for such slow or extended release.

0125As used herein, the phrase "conjoint administration" refers to any form of administration of two or more different therapeutic agents such that the second agent is administered while the previously administered therapeutic agent is still effective in the body (e.g., the two agents are simultaneously effective in the patient, which may include synergistic effects of the two agents). For example, the different therapeutic compounds can be administered either in the same formulation or in separate formulations, either concomitantly or sequentially. Thus, an individual who receives such treatment can benefit from a combined effect of different therapeutic agents.

0126A "therapeutically effective amount" or a "therapeutically effective dose" of a drug or agent is an amount of a drug or an agent that, when administered to a subject will have the intended therapeutic effect. The full therapeutic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations. The precise effective amount needed for a subject will depend upon, for example, the subject's size, health and age, and the nature and extent of the condition being treated, such as cancer or MDS. The skilled worker can readily determine the effective amount for a given situation by routine experimentation.

0127As used herein, the terms "optional" or "optionally" mean that the subsequently described event or circumstance may occur or may not occur, and that the description includes instances where the event or circumstance occurs as well as instances in which it does not.

Discussion

0184Adenocarcinoma of the prostate (PCa) is the most common non-cutaneous solid tumor diagnosed in men in the U.S. and represents the second leading cause of cancer-related mortality in men, second only to lung cancer. PCa is initially androgen dependent (AD), and androgen deprivation therapy (ADT), which is delivered by surgical or chemical castration in the form of luteinizing hormone releasing hormone (LHRH) analogues (<figref idref="f0004">Figure 5A</figref>), results in apoptosis and growth arrest of AD PCa cells and induces a clinical response in virtually all patients. Unfortunately, castration resistant prostate cancer (CRPC) inevitably develops and not only represents the terminal phase of the disease with a median survival of approximately 12-15 months, but also is associated with profound morbidity. Until recently, the chemotherapeutic agent, docetaxel, was the only systemic therapy for CRPC that prolonged median overall survival, albeit by a modest two to three months. In 2010, another cytotoxic chemotherapeutic, cabazitaxel, was also granted regulatory approval for docetaxel-resistant patients based on a three month improvement in survival, as was the cellular vaccine, Provenge, which extended survival by four months in a highly select sub-group of patients with excellent performance status. Thus, despite these modest, incremental advances, novel treatment approaches based on an understanding of the biology behind castration resistance are required to more substantially improve the outcomes of CRPC patients.

0185A large body of experimental and clinical evidence has established that restoration of AR activity underlies therapeutic resistance in the vast majority of CRPC patients. Although the AR has non-genotropic effects, reactivation of AR transcriptional activity represents the principal biochemical driving force that is necessary and sufficient for castration resistance. Cellular adaptations, including 1) AR gene amplification, 2) intratumoral steroidogenesis, 3) gain-of-function AR gene mutations that allow for ligand promiscuity, 4) somatic mosaicism of the AR, 5) heightened expression of AR transcriptional coactivators, 6) as well as truly ligand-independent AR activation mediated by growth factors, cytokines, and AR phosphorylation, are mutually non-exclusive mechanisms that drive AR transcriptional activity despite castrate serum levels of androgens. Activating mutations of the AR signaling axis has been identified in nearly all cases of CRPC in a recent integrative genomic analysis of over 200 CRPC patients.

0186Based on these observations, drugs that target the AR signaling axis through novel approaches, including pure AR antagonists (e.g. enzalutamide) and CYP17 inhibitors aimed at inhibiting intratumoral steroidogenesis (e.g. abiraterone acetate) have made their way through the clinic (<figref idref="f0004">Figure 5B</figref>). Abiraterone acetate and enzalutamide have both been approved for the treatment of metastatic CRPC (mCRPC). However, primary resistance to these agents occurs in roughly one third of patients, while the remaining patients develop secondary resistance manifested by progression of disease after an initial period of response of variable duration.

0187The phase 3 studies that demonstrated the clinical success of abiraterone acetate and enzalutamide in chemotherapy naive and post-chemotherapy patients confirmed the pathophysiologic relevance of the AR as a driver of castration resistance. Cross-resistance between abiraterone and enzalutamide is the norm as evidenced by the low response rate when one of these agents is used subsequent to progression on the other. Since the clinical implementation of these second-generation endocrine therapies, pre-clinical models as well as sequencing studies of cohorts of mCRPC patients have demonstrated ongoing AR expression and signaling in post-abiraterone/post-enzalutamide mCRPC. In fact, the AR is the most frequently mutated gene, and an AR-dependent transcriptional program is reactivated in this context. Thus, the AR represents a key driver of castration resistant growth in both newly developed CRPC and post-abiraterone/post-enzalutamide CRPC.

0188Constitutively active variants of the AR that lack a functional LBD have recently been shown to be expressed in prostate cancer specimens with increasing frequency in mCRPC specimens. These constitutively active variants confer resistance to abiraterone acetate and enzalutamide; in fact, these variants would not be expected to respond to any existing drug that directly or indirectly targets the LBD. Given the inevitable development of primary or secondary resistance to abiraterone and enzalutamide and the pathophysiologic relevance of the AR throughout the natural and treated history of the castration resistant state, there is an unmet need to develop novel AR targeting agents to improve the clinical outcomes of patients with metastatic CRPC.

0189All existing endocrine therapies in clinical use for the treatment of PCa, including but not limited to abiraterone and enzalutamide, directly or indirectly target the C-terminal ligand binding domain (LBD) of the AR. The C-terminal LBD of the AR represents the direct or indirect molecular target of new AR targeting agents in development as well as those that have long been employed, including luteinizing hormone releasing hormone (LHRH) analogues (e.g. leuprolide, a "chemical castration") and partial AR antagonists (e.g. bicalutamide) (<figref idref="f0004">Figure 5C</figref>). The other major domains of the AR, including the centrally located DNA binding domain (DBD) and N-terminal transactivation domain (TAD), have yet to be directly targeted and exploited for therapeutic benefit. These domains are required for AR transcriptional activity, yet no drug that targets either of these domains has been successfully brought to the point of regulatory approval to date. The centrally located DBD shares significant homology with other members of the nuclear steroid receptor family (e.g. glucocorticoid receptor [GR], progesterone receptor [PR]), whereas the N-terminally located AR TAD shares the least homology with that of other members of this family and accordingly could be selectively targeted.

0190The AR TAD is an intrinsically disordered protein that has not been amenable to crystallization. Hence, its structure has not been resolved, and, by extension, the AR TAD does not lend itself to structure based drug design. Proof-of-principle support for the notion of targeting the TAD has come from studies in which TAD decoy molecules inhibited AR-dependent growth.

0191Proof-of-principle support for the notion of targeting the TAD has come from recent studies by a group that identified TAD decoy molecules as well as a marine sponge extract that selectively targets the AR TAD. Importantly, this marine sponge extract, known as EPI-001, inhibited CRPC growth through interaction with the AF 1 region of the TAD. EPI-001 was not identified through a high throughput screen, and is likely to have been absorbed by marine sponges in vivo as an industrial compound. Other compounds have been shown to have an inhibitory effect on constitutively active AR splice variants. Galeterone binds to the AR LBD but was reported to induce degradation of AR splice variants. Galeterone entered into clinical trials, but a phase 3 studied was recently discontinued at an interim analysis due to futility. Niclosamide, an anti-fungal agent, also inhibits AR splice variants and has entered into early phase clinical trials.

0192It has been discovered that compound JN018 exhibits potent, specific AR inhibitory effects: <chemistry id="chem0029" num="0029"><img file="EP4397652A2_D0029.tif" /></chemistry>

0193In particular, JN018 has the following properties: (1) AR TAD is its molecular target. (2) JN018 exhibits direct, selective, high affinity covalent binding to the AR. (3) JN018 induces rapid degradation of the full-length AR (ARFL) and constitutively active AR splice variants (ARSV) that lack a functional LBD. (4) JN018 exhibits selective cytoreductive effects on AR-expressing prostate cancer cell lines, including ARSV expressing cell lines. (5) JN018 causes growth inhibition of castration resistant prostate cancer xenografts. (6) JN018 inhibits AR-driven gene expression.

0194For example, JN018 inhibits reporter activity driven by the ARE and MMTV promoters, but does not affect GR, AP1, or CREB mediated reporter activity. Importantly, JN018 inhibits the reporter activity of the endogenously and ectopically expressed full-length AR and AR-V7 (constitutively active AR splice variant) in the following cell systems: 1) LNCaP, which endogenously expresses full length AR, 2) LNCaP-AR, which is engineered to overexpress full length AR to recapitulate castration resistance, 3) 22Rv1, which expresses both full-length AR and the constitutively active ARV7, and 4) PC3 cells, which are AR null but were transfected with constitutively active ARΔ567.

0195In addition to JN018, a number of additional compounds have been prepared and tested, as listed in Table 1: <tables id="tabl0001" num="0001"><img file="EP4397652A2_D0030.tif" /></tables><tables id="tabl0002" num="0002"><img file="EP4397652A2_D0031.tif" /></tables><tables id="tabl0003" num="0003"><img file="EP4397652A2_D0032.tif" /></tables><tables id="tabl0004" num="0004"><img file="EP4397652A2_D0033.tif" /></tables><tables id="tabl0005" num="0005"><img file="EP4397652A2_D0034.tif" /></tables><tables id="tabl0006" num="0006"><img file="EP4397652A2_D0035.tif" /></tables><tables id="tabl0007" num="0007"><img file="EP4397652A2_D0036.tif" /></tables>

0196The compounds disclosed herein are believed to the first AR degraders that directly target the TAD. By eliminating the AR and its splice variants, these compounds offer the promise of overcoming AR-dependent castration resistance irrespective of the underlying molecular mechanism(s), including but not limited to the expression of constitutively active ARSVs that lack a functional C-terminal LBD.

General Materials and Methods

0199All solvents and reagents were purchased from commercial sources and used without further purification unless otherwise noted. Acetonitrile (MeCN), toluene (calcium hydride), dichloromethane (DCM), diethyl ether (EtO₂), and tetrahydrofuran (THF) used for the reactions were dried by distillation over calcium hydride (MeCN, toluene, DCM) or sodium (EtO₂, THF). All reactions were performed under an inert atmosphere of dry argon and monitored by thin layer chromatography (TLC) on pre-coated EMD silica gel 60 F₂₅₄ TLC aluminum sheets and visualized with a UV lamp. Flash column chromatography was performed on SiliaFlash P60 (SiliCycle Inc.) silica gel (40-63 µm, 60 Å pore size). NMR spectra were obtained on Bruker AV400 and AV500 instruments at the UCLA MIC Magnetic Resonance Laboratory. NMR data were analyzed using the MestReNova NMR software (Mestrelab Research S. L., version 11.0.2). Chemical shifts (δ) are expressed in ppm and are internally referenced for ¹H NMR (CHCl₃ 7.26 ppm, DMSO-<i>d</i>₆ 2.50 ppm) and ¹³C NMR (CDCl₃ 77.16 ppm, DMSO-<i>d</i>₆ 39.52 ppm). DART-MS spectra were collected on a Thermo Exactive Plus MSD (Thermo Scientific) equipped with an ID-CUBE ion source and a VAPUR Interface (IonSense). Both the source and MSD were controlled by Excalibur, version 3.0. The analyte was spotted onto OpenSpot sampling cards (IonSense) using DCM or chloroform as the solvent. Ionization was accomplished using He plasma with no additional ionization agents. Melting points were recorded on a Büchi^® B-545 melting point apparatus. Analytical HPLC was performed on a 2.0 × 50 mm Waters Corp. 1.5 µm C18 analytical HPLC column. A linear gradient of mobile phase was used over 5 min from 5 - 95% MeCN/water containing 0.2% HCOOH. The flow rate was 0.4 mL/min and the peaks were detected by a LCT-Premier ESI-TOF mass spectrometer in the positive ion mode.

<u>Example 3: Biological Assays Conducted on Exemplary Compounds</u>

0254The inhibitory activity of JN018 was further evaluated in experiments in which the AR transactivation domain (TAD) or the c-Jun or CREB TAD was fused to the heterologous GAL4 DNA-binding domain and thereby drive reporter gene expression governed by the GAL4 response element (<figref idref="f0001">Figure 1</figref>). JN018 selectively inhibits the AR-GAL4-DBD fusion protein, which indicates that JN018 targets AR activity through the AR TAD.

0255Next, the effects of the compounds on growth of prostate cancer cell lines in vitro were evaluated. JN018 inhibits the growth of AR expressing prostate cancer cells including those that express the AR splice variants, but not AR null cells (<figref idref="f0002">Figure 2</figref>).

0256Similar assays were performed on the compounds prepared above, as well as enzalutamide (MDV3100). The results are summarized in Table 3. <tables id="tabl0009" num="0009"><table frame="all"><title><u>Table 3: Assay Results</u></title><tgroup cols="11"><colspec colnum="1" colname="col1"

<u>Example 4: Further Evaluation of JN018</u>

0257JN018 was further evaluated to identify a mechanism for its activity in prostate cancer cell lines. It was discovered that JN018 inhibits the expression of AR regulated genes. Specifically, JN018 reduces expression of TMPRSS and NDRG in a dose-dependent fashion (<figref idref="f0002">Figure 3</figref>). Interestingly, JN018 also reduces both full length AR and AR-V7 expression. In principle, decreased AR expression can be attributed to several different effects, such as gene transcription, mRNA stability, translation, or protein stability.

0258In protein stability experiments with cycloheximide to inhibit protein translation, JN018 reduced the half-life (t_1/2) of full length AR in LNCaP-AR cells (<figref idref="f0003">Figure 4A</figref>). Given that JN018 seems to function through the AR TAD (see <figref idref="f0001">Figure 1</figref>), the impact of JN018 on full-length and splice variant AR was studied next. JN018 potently reduced the t_1/2 of both full length and splice variant AR (<figref idref="f0003">Figure 4B</figref>). JN018 also enhanced degradation of an AR splice variant known as AR Δ567 that was stably introduced into PC3 cells, which lack endogenous AR expression. This indicates that the effect of JN018 on AR splice variant degradation does not require the presence of the full-length AR. Not only did JN018 induce degradation of the AR in a time-dependent fashion, but also in a dose-dependent fashion. JN018 did not affect the t_1/2 of c-Jun or actin (<figref idref="f0003">Figure 4</figref>), nor that of the closely related glucocorticoid receptor. These results suggest that JN018 may be an effective therapy for heavily treated CRPC, in which expression of the constitutively active splice variant represents a mechanism of resistance to novel AR targeting agents such as enzalutamide and abiraterone acetate. Because JN018 targets the N-terminal domain of the AR, JN018 may demonstrate growth inhibitory effects in prostate cancer cells that exhibit resistance to AR targeting therapies in a mechanism that is independent of constitutively active splice variants. IC₅₀s and K_Ds determined during these studies are listed in Table 4. <tables id="tabl0010" num="0010"><table frame="all"><title><u>Table 4: Inhibition and Binding Parameters of JN018</u></title><tgroup cols="4"><colspec colnum="1" colname="col1" colwidth="33mm" align="center" /><colspec colnum="2" colname="col2" colwidth="41mm" align="center" /><colspec colnum="3" colname="col3" colwidth="31mm" align="center" /><colspec colnum="4" colname="col4" colwidth="38mm" align="center" /><thead valign="top"><row><entry>IC₅₀ for AR inhibition</entry><entry>IC₅₀ for Growth Inhibition</entry><entry>K_D for AR Binding</entry><entry>IC₅₀ for AR Degradation</entry></row></thead><tbody><row><entry>0.11 µM</entry><entry>1.5 µM</entry><entry>7.3×10^-9</entry><entry>∼2.0 µM</entry></row></tbody></tgroup></table></tables>

<u>Example 5: Further Evaluation of Additional compounds</u>

0259A number of variations on JN018 have been prepared and tested, as described herein, for example, a series of compounds was prepared the β-dialkylamino dienone R₁ (hereafter referred to as R₁) moiety has undergone SAR analysis. The first compound in this series is JN097; other analogues are denoted with numbers > 097. Based on SAR analysis performed to date, Ar₁ and Ar₂ are critical to the specificity of JN018, whereas R₁ is hypothesized to function as the "warhead" that confers androgen receptor inhibitory activity.

0260The synthetic approach to JN018 and its analogs is shown in <figref idref="f0004"><b>Figure 7</b></figref><b>.</b> Phenylacetones are reacted with benzaldehydes to undergo Knoevenagel condensation, giving rise to (<i>E</i>)-3,4-diarylbut-3-en-2-ones of general structure <b>2.</b> These methyl ketones are then reacted under Mannich reaction conditions to yield β-dialkylamino dienones <b>3</b> as a separable mixture of <i>E</i> (active) and <i>Z</i> (inactive) stereoisomers. In this series of compounds, substitutions have been made to the right-hand part of the molecule (i.e. R₁). <b>JN097</b>, in which an epoxide has replaced the β-dialkylamino enone, exhibits enhanced growth inhibitory effects as compared to JN018 (<figref idref="f0005"><b>Figure 8</b></figref>).

0261Further modifications of R₁ yielded compounds with a spectrum of growth suppressive effects. Of note, JN102 and JN103 exhibited improved growth suppressive effects, but JN104-112 did not (<figref idref="f0007 f0008"><b>Figure 10</b></figref>). JN102 and 103 suppressed growth of AR expressing cells (LAPC4, 22Rv1, CWR22, and LNCaP-AR), but did not influence growth of AR null prostate cancers (PC3 and DU145) or lung cancer cells (A549, not shown).

0262JN097, 102 and 103 inhibited reporter activity driven by tandem copies of the androgen response element (ARE) but not the glucocorticoid response element (GRE) (<figref idref="f0006"><b>Figure 9</b></figref>). Analogous to JN018, JN097, 102, and 103 accelerated the degradation (i.e. shorten the half-life) of the AR (not shown).

0263Additional compounds have been generated with sequential numbering through JN136. In vitro biologic activity and biochemical activity/selectivity for AR inhibition have been tested for JN104-133. JN118 and 121 demonstrated improved in vitro growth inhibitory effects with reduced off target effects on AR-expressing and AR-null prostate cancer cell lines, respectively, compared to the parent compound JN018. JN128 has also shown selective growth inhibitory effects. In addition to the excellent growth inhibitory profile of JN118 and JN121, these two compounds also demonstrated excellent inhibitory effects on AR transcriptional activity in several reporter systems (MMTV reporter, ARE reporter, and PSA promoter/enhancer reporter) with minimal effects on non-AR-dependent reporter systems.

0264Selected compounds were tested in a mouse xenograft model. In this model, the LNCaP-AR castration resistant cell line was grown subcutaneously in the flanks of castrated nude mice. When tumors reached 150-200 mm³, mice were administered selected JN series compounds, vehicle or positive control by oral gavage once per day for five days per week (Mon-Fri). JN018 exhibited similar activity as enzalutamide (<figref idref="f0010"><b>Figure 12A</b></figref>), although some mice exhibited signs of toxicity with increased duration of drug treatment. JN090, JN103, and JN121 were subsequently tested and demonstrated anti-tumor effects (<figref idref="f0011"><b>Figure 12B</b></figref>) with limited or no outward signs of toxicity (<figref idref="f0011"><b>Figure 12B</b></figref>).
