## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application Ser. No. 61/367,612, filed Jul. 26, 2010, incorporated herein by reference in its entirety.
DESCRIPTION
The present invention generally relates to sulfonamide compounds useful as CYP17 inhibitors. Provided herein are sulfonamide compounds, compositions comprising such compounds, and methods of their use. The invention further pertains to pharmaceutical compositions comprising at least one compound according to the invention that is useful for the treatment of conditions related to the CYP17 enzyme, such as cancer and other proliferative diseases.
Prostate cancer is the second leading cause of cancer related mortality in American men. In 2007, there were 218,890 new cases with 27,000 deaths associated with prostate cancer. It is well known that androgens, such as testosterone and dihydrotestosterone, drive the growth of the prostate as well as prostate cancer at the level of the androgen receptor. The standard of care for advanced hormone sensitive prostate cancer involves surgical or chemical castration with a leutenizing releasing hormone agonist/antagonist to remove the androgens produced in the gonads from circulation. However, approximately 90% of androgens are produced in the testes with the remaining 10% being produced through the action of the adrenal gland. Thus, castration does not alleviate the action of all androgens. Further once a patient progresses to castration resistant prostate cancer, androgens are also produced at the level of the tumor, making treatment with antiandrogens more difficult.
The cytochrome P450 monooxygenase 17α-hydroxylase/17,20-lyase (CYP17) is responsible for the biosynthesis of both dihydroepiandrostenedione and androstenedione which are precursors of both androgens and estrogen. Thus the production of androgens and estrogens in the human body is mediated by CYP17. Blocking this enzyme would inhibit the production of gonadal, adrenal, and tumoral androgens and could offer a new treatment option for prostate cancer and estrogen receptor-positive breast cancer patients. Clinical proof-of-concept for CYP17 as a target for prostate cancer has been achieved with the antifungal ketoconazole and the steroidal CYP17 inhibitor abiraterone, which has progressed to Phase III clinical trials for prostate cancer. Despite the advances recently made in the art, there is a clear need for new compounds that are useful as inhibitors of CYP17 enzymes.
Applicants have found potent sulfonamide compounds that have activity as CYP17 inhibitors, and these compounds may be useful for the treatment of conditions related to the CYP17 enzyme.
Certain sulfonamide compounds have been reported in patent publications. Such publications, for example, include the following: WO 01/82916; WO 2004/113279; U.S. 2007/0287708; U.S. 2008/003949; WO 2008/042867; WO 2008/136378; U.S. 2004/0048891; U.S. 2006/0030543; U.S. 2008/0167348; U.S. 2006/0258671; and WO 2010/005922.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; and alkali or organic salts of acidic residues such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th Edition, p. 1418, Mack Publishing Company, Easton, Pa. (1985), the disclosure of which is hereby incorporated by reference.
Salt(s) of the Formula (I) compounds can be formed by, for example, reacting a Formula (I) compound with, for example, an equivalent amount of acid or base in a medium that allows the newly formed salt to, for example, either be precipitated out, or be isolated via lyophilization.

Such salts can be formed in accordance with methods known to a person of ordinary skill in the art.
Exemplary basic salt(s) that the compounds of Formula (I) can form with inorganic and/or organic bases include, but are not limited to, for example, ammonium salts; alkali metal salts, such as, for example, sodium, lithium and potassium salts: alkaline earth metal salts, such as, for example, calcium and magnesium salts; salts formed with organic bases, such as, for example, benzathines, dicyclohexylamines, 2-amino-2-(hydroxymethyl)propane-1,3-diol (trisamine or tris), hydrabamines (such as, for example, N,N-bis(dehydroabietyl)ethylenediamine), N-methyl-D-glucamines, N-methyl-D-glycamides, and t-butyl amines; salts formed with amino acids, such as, for example, arginine and lysine; and salts formed by using agents, such as, for example, lower alkyl halides (e.g., methyl, ethyl, propyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g., dimethyl, diethyl, dibutyl, and diamyl sulfates), long chain halides (e.g., decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides), and aralkyl halides (e.g., benzyl and phenethyl bromides) to quaternize basic nitrogen-containing groups. Such salts can be formed in accordance with methods known to a person of ordinary skill in the art.
The term “protecting group” refers to a substituent that is commonly employed to block or protect a particular functionality while reacting with other functional group on the compound. For a general description of protection groups and their use, see Greene, T.W., Protective Groups In Organic Synthesis”, John Wiley & Sons, New York (1991).
Compounds of the Formula (I) may also have prodrug forms. Any compound that can be converted in vivo to provide the bioactive agent (i.e., the compound of Formula (I)) is a prodrug within the scope and spirit of the invention.
The term “prodrugs” as employed herein includes esters and carbonates formed by reacting one or more hydroxyls of compounds of Formula (I) with alkyl, alkoxy, or aryl substituted acylating agents employing procedures known to those skilled in the art to generate acetates, pivalates, methylcarbonates, benzoates, and the like.

As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state.
Compounds of the present invention may contain one or more additional asymmetric carbon atoms and therefore exist in two or more stereoisomeric forms. The present invention includes all of the possible individual stereoisomers, the individual tautomeric forms thereof, together with mixtures thereof. Separation of diastereoisomers may be achieved by conventional techniques, e.g., by fractional crystallization, chromatography or HPLC of a stereoisomeric mixture of a compound of the present invention, or a suitable salt or derivative thereof. An individual enantiomer of the compound may also be prepared from a corresponding optically pure intermediate or by resolution, such as by HPLC of the corresponding racemate using a suitable chiral support or by fractional crystallization of the diastereoisomeric salts formed by reaction of the corresponding racemate with a suitable optically active acid or base, as appropriate. All stereoisomers of the compounds of the instant invention are contemplated, either in admixture or in pure or substantially pure form.
The compounds of the present invention are intended to include all isotopes of atoms occurring in the present compounds. Isotopes include those atoms having the same atomic number but different mass numbers. By way of general example and without limitation, isotopes of hydrogen include deuterium and tritium. Isotopes of carbon include 13C and 14C. Isotopically-labeled compounds of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed.
Also embraced within this invention is a class of pharmaceutical compositions comprising the compounds of Formula (I), or stereoisomers, or pharmaceutically acceptable salts thereof in association with one or more non-toxic, pharmaceutically-acceptable carriers and/or diluents and/or adjuvants (collectively referred to herein as “carrier” materials) and, if desired, other active ingredients. The compounds of Formula (I) may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. The compounds and compositions of the present invention may, for example, be administered orally, mucosally, or parentally including intravascularly, intravenously, intraperitoneally, subcutaneously, intramuscularly intrasternally and infusion techniques, in dosage unit formulations containing conventional pharmaceutically acceptable carriers, adjuvants, and vehicles. For example, the pharmaceutical carrier may contain a mixture of mannitol or lactose and microcrystalline cellulose. The mixture may contain additional components such as a lubricating agent, e.g., magnesium stearate and a disintegrating agent such as crospovidone. The carrier mixture may be filled into a gelatin capsule or compressed as a tablet.
The pharmaceutically active compounds of this invention can be processed in accordance with conventional methods of pharmacy to produce medicinal agents for administration to patients, including humans and other mammals.
For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension, or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are tablets or capsules. For example, these may contain an amount of active ingredient from about 0.05 to 2000 mg, preferably from about 0.05 to 500 mg, more preferably from about 0.05 to 150 mg. A suitable daily dose for a human or other mammal may vary widely depending on the condition of the patient and other factors, but, once again, can be determined using routine methods.
The amounts of compounds that are administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex, the medical condition of the subject, the type of disease, the severity of the disease, the route and frequency of administration, and the particular compound employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. A daily dose of about 0.01 to 1500 mg/kg body weight, preferably about 0.05 to 50 mg/kg body weight, and most preferably about 0.05 to 20 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day.
For therapeutic purposes, the active compounds of this invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered orally, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinyl alcohol, and/or polyvinylpyrrolidone, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose.
The oily phase of the emulsions comprising compounds of Formula (I) may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make-up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, sodium lauryl sulfate, glyceryl distearate alone or with a wax, or other materials well known in the art.
The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used.
Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules using one or more of the carriers or diluents mentioned for use in the formulations for oral administration or by using other suitable dispersing or wetting agents and suspending agents.

UTILITY
The compounds of Formula (I) are useful for the treatment of cancer, for example, cancers dependent upon androgen receptor signaling. These compounds inhibit the activity of the CYP17 enzyme, which is involved in biosynthesis of androgens. Blocking this enzyme would inhibit the production of gonadal, adrenal, and tumoral androgens and could offer a new treatment option for cancers dependent upon androgen receptor signaling, such as prostate cancer and estrogen receptor-positive breast cancer patients. Thus, the treatment comprises administering to the patient a compound of Formula (I), or a stereoisomer, or a pharmaceutically acceptable salt thereof.
In one embodiment, a method is provided for treating cancer comprising administering a compound of Formula (I), a stereoisomer, or a pharmaceutically acceptable salt thereof. The method of this embodiment can be used to treat a variety of cancers, including, but not limited to, breast cancer, ovarian cancer, and prostate cancer. Preferably, the method of this embodiment is used to treat prostate cancer and/or breast cancer. In one method of this embodiment, the compound of Formula (I), a stereoisomer, or a pharmaceutically acceptable salt thereof is administered in a therapeutically effective amount.
In one embodiment, provided are methods for treating cancer in a patient wherein the cancer is dependent upon CYP17 activation, comprising administering to the patient in need thereof a therapeutically effective amount of a compound of Formula (I), a stereoisomer, or a pharmaceutically acceptable salt thereof. In one method of this embodiment, a compound of Formula (I), a stereoisomer, or a pharmaceutically acceptable salt thereof is administered to treat prostate cancer. In another method of this embodiment, a compound of Formula (I), a stereoisomer, or a pharmaceutically acceptable salt thereof is administered to treat breast cancer. Preferably, a therapeutically effective amount of Compound (I), a stereoisomer, or a pharmaceutically acceptable salt thereof is administered.
The amount of a compound of Formula (I) which is administered and the dosage regimen for treating a particular cancer depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the type of disease, the severity of the disease, the route and frequency of administration, and the particular compound employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. A daily dose of about 0.01 to 500 mg/kg body weight, preferably about 0.05 to 50 mg/kg body weight, and most preferably about 0.05 to 20 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day.
In treating cancer, a combination of chemotherapeutic agents and/or other treatments (e.g., radiation therapy) is often advantageous. The second (or third) agent may have the same or different mechanism of action than the primary therapeutic agent. It may be especially useful to employ cytotoxic drug combinations wherein the two or more drugs being administered act in different manners or in different phases of the cell cycle, and/or where the two or more drugs have overlapping toxicities or side effects, and/or where the drugs being combined each has a demonstrated efficacy in treating the particular disease state manifested by the patient.
Accordingly, a compound of Formula (I) may be administered in combination with other anti-cancer treatments useful in the treatment of cancer or other proliferative diseases. The invention herein further comprises use of a compound of Formula (I) in preparing medicaments for the treatment of cancer, and/or it comprises the packaging of a compound of Formula (I) herein together with instructions that the compound be used in combination with other anti-cancer or cytotoxic agents and treatments for the treatment of cancer. The present invention further comprises combinations of a compound of Formula (I) and one or more additional agents in kit form, e.g., where they are packaged together or placed in separate packages to be sold together as a kit, or where they are packaged to be formulated together.
The compound of Formula (I) can be formulated or co-administered with other therapeutic agents that are selected for their particular usefulness in addressing side effects associated with the aforementioned conditions. For example, the compound of Formula (I) may be formulated with agents to prevent nausea, hypersensitivity and gastric irritation, such as antiemetics, and H1 and H2 antihistaminics.
The phrase “anti-cancer treatment” includes but is not limited to, for example, radiation therapy and surgery.
The other anti-cancer agents may be selected from any one or more of the following: alkylating agents (including nitrogen mustards, alkyl sulfonates, nitrosoureas, ethylenimine derivatives, and triazenes); anti-angiogenics (including matrix metalloproteinase inhibitors); antimetabolites (including adenosine deaminase inhibitors, folic acid antagonists, purine analogues, and pyrimidine analogues); antibiotics or antibodies (including monoclonal antibodies, CTLA-4 antibodies, anthracyclines); aromatase inhibitors; cell-cycle response modifiers; enzymes; farnesyl-protein transferase inhibitors; hormonal and antihormonal agents and steroids (including synthetic analogs, glucocorticoids, estrogens/anti-estrogens [e.g., SERMs], androgens/anti-androgens, progestins, progesterone receptor agonists, and luteinizing hormone-releasing [LHRH] agonists and antagonists); insulin-like growth factor (IGF)/insulin-like growth factor receptor (IGFR) system modulators (including IGFR1 inhibitors); integrin-signaling inhibitors; kinase inhibitors (including multi-kinase inhibitors and/or inhibitors of Src kinase or Src/abl, cyclin dependent kinase [CDK] inhibitors, panHer, Her-1 and Her-2 antibodies, VEGF inhibitors, including anti-VEGF antibodies, EGFR inhibitors, mitogen-activated protein [MAP] inhibitors, MEK inhibitors, Aurora kinase inhibitors, PDGF inhibitors, and other tyrosine kinase inhibitors or serine/threonine kinase inhibitors; microtubule-disruptor agents, such as ecteinascidins or their analogs and derivatives; microtubule-stabilizing agents such as taxanes, and the naturally-occurring epothilones and their synthetic and semi-synthetic analogs; microtubule-binding, destabilizing agents (including vinca alkaloids); topoisomerase inhibitors; prenyl-protein transferase inhibitors; platinum coordination complexes; signal transduction inhibitors; and other agents used as anti-cancer and cytotoxic agents such as biological response modifiers, growth factors, and immune modulators.

METHODS OF PREPARATION
The compounds of the present invention may be prepared by synthetic routes that include processes analogous to those well-known in the chemical arts, particularly in light of the description provided herein. For illustrative purposes, general Schemes 1 to 8 below show general methods for preparing the compounds of the present invention, as well as key intermediates. For a more detailed description of the individual reaction steps, see the Example section below. Those skilled in the art will appreciate that other synthetic routes may be used to synthesize the inventive compounds. Although specific starting material and reagents are depicted in the Schemes and discussed below, other starting materials and reagents can be easily substituted to provide a variety of compounds of the present invention. In addition, many of the compounds prepared by the methods below can be further modified in light of this disclosure using conventional chemistry well known to those skilled in the art.
As shown in Scheme 1, for instance a 3-pyridylboronic acid or ester II can be coupled to an aryl halide of type III, where P is a common protecting group known to those skilled in the art, via standard Suzuki coupling conditions to give a coupled product of general structure IV. Removal of protecting group via standard conditions gives the aniline of general structure V. Treatment of the aniline with a sulfonyl chloride VI in the presence of an organic base such as triethylamine, will give the desired sulfonamide of general structure (I).




Alternatively, the boronic acid or ester of general structure II (Scheme 2) can be coupled with an aryl halide of general structure VII where the sulfonamide functionality is already present under standard Suzuki coupling conditions to give products of general structure (I).




Scheme 3 depicts another preparation beginning with sulfonamides of general structure VII where G is bromo or iodo. Treatment of the halide at low temperature with excess alkyl lithium, such as tertiary butyl lithium, followed by trapping of the resultant anion with a boronic ester such as pinacol borane, will give products of general structure VIII with a boronic ester para to the sulfonamide. This boronic ester can then be coupled to the 3-bromopyridine of general structure IX under standard Suzuki conditions to afford compounds of general structure (I).




Starting with the commercial pyridine X, treatment with PBr5 will afford the tribromide XI. Substitution at the 4-position of XI with various alkoxides and amines under conditions well-known to one skilled in the art will afford compounds of general structure XII. Standard Suzuki coupling with the boronic acid/ester VIII will give compounds of general structure XIII. Functionalization at the 5-position of the pyridine in XIII via Suzuki or Buchwald coupling will give compounds of general structure (I).




An alternative coupling strategy is shown in Scheme 5. Treatment of optionally substituted pyridines of general structure XIV with an organolithium such as LDA followed by addition of ZnCl2 and Pd(O) in the presence of an aryl halide such as the bromide of general structure XV, will afford the coupled product of general structure XVI. The 4-position of the pyridine can then be further functionalized by chemistry well-known to one skilled in the art such as Suzuki couplings with aryl boronic acids to afford compounds of general structure XVII. Reduction of the nitro group under standard conditions such as iron/acetic acid or Pd catalyzed hydrogenation will afford the aniline of general structure V which can be converted to the sulfonamide of general structure (I) by methods discussed previously.




Sulfamides can were also prepared and are encompassed by general Formula (I). Treatment of the aniline V with chlorosulfonylisocyanate and 2-hydroxychloroethane in the presence of Hunig's base gives the intermediate oxazolidinone of structure XVIII. Subsequent treatment with an amine at high temperatures, such as 80° C. in CH3CN, will give the sulfamide of general structure XIX, which is a structure of general Formula (I).




Substituted pyrimidines can also be prepared from the commercially available 4-chloro-5-iodo-pyrimidine XX. Treatment of this pyrimidine with an amine in a solvent such as DMSO and cesium carbonate will afford the 4-aminopyridimine of structure XXI. This intermediate can then be coupled to boronic acids/esters of general structure VIII under standard Suzuki coupling conditions to afford compounds of general structure XXII which is a compound of general Formula (I).




In a similar manner, the 4-alkoxy-pyrimidines of general structure XXIII can be prepared leading to compounds of general structure XXIV which is a compound of general Formula (I).

Example 178
N-(3-Chloro-4-(4-methylpyridin-3-yl)phenyl)methanesulfonamide




To a solution of Intermediate 27 (0.102 g, 0.466 mmol) and methanesulfonyl chloride (0.043 mL, 0.560 mmol) in DMF (3.26 mL) was added sodium hydride (0.037 g, 0.933 mmol) at room temperature. The reaction mixture was allowed to stir at room temperature for 3 days, then quenched with saturated aqueous NH4Cl solution and diluted with EtOAc. The layers were separated and the aqueous phase was extracted with EtOAc (5×). The organic phases were combined, dried over Na2SO4, filtered, and concentrated to afford a yellow residue, which was further dried under high vacuum. The crude material was dissolved in CH2Cl2 and purified by silica gel chromatography using an ISCO machine (12 g column, 30 mL/min, 0-10% MeOH in CH2Cl2 over 25 min, tr=14 min) to afford the title compound (5.1 mg, 0.016 mmol, 3.54% yield) as a white solid.

Biological Assays
The pharmacological properties of the compounds of this invention may be confirmed by a number of biological assays. The exemplified biological assays, which follow, have been carried out with the compounds of the present invention.
CYP17 Total SPA Assay
The assays were performed in U-bottom 384-well optiplates. The final assay volume was 15 μl prepared from 7.5 μl additions of microsomes (prepared as a high-speed pellet from homogenized HEK2 cells stably transfected with CYP17), substrates (3H-Pregnenolone and NADPH) and test compounds in assay buffer (50 mM Potassium phosphate pH 7.2, 10% glycerol). The reaction was initiated by the combination of the microsomes and substrates in wells containing compound. The reaction was incubated at room temperature for 45 minutes and terminated by adding 7.5 μl of 0.2N HCl to each well. Following an incubation period of 10 minutes, anti-DHEA-coated SPA beads were added to the terminated reaction. The plate was sealed and incubated overnight with shaking at 4° C. The beads were allowed to settle in the plate for 1 hour and the plate read on a TOPCOUNT® (Perkin-Elmer) plate reader.
Inhibition data were calculated by comparison to no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentration of reagents in the assays are NADPH, 2 mM; 3H-Pregnenolone, 1 uM; microsomes, 1.25 ug/ml; Anti-DHEA-SPA beads (0.125 mg/well) in 0.5% Triton X-100 and DMSO, 0.05%. Dose response curves were generated to determine the concentration required inhibiting 50% of enzyme activity (IC50). Compounds were dissolved at 10 mM in dimethylsulfoxide (DMSO) and evaluated at eleven concentrations, each in duplicate. IC50 values were derived by non-linear regression analysis.
Table 22 below lists the IC50 values for the following Examples of this invention measured in the Total CYP17 SPA Assay hereinabove. The compounds of the present invention, as exemplified by the following Examples, showed Human CYP17 SPA IC50 values of less than 1 μM.

CYP17 Lyase Assay

Human CYP17 was expressed in HEK293 cells and microsomal preparations were made and subsequently used as the source of enzyme in the lyase assay. The reaction consists of 200 nM [3H]-Hydroxypregnenolone (ARC), 200 nM 17-Hydroxypregnenolone (Sigma), 2 mM NADPH (CalBiochem), and CYP17-HEK293 microsomes which were incubated in the presence of DMSO or test compounds for 20 minutes at room temperature. Compounds were dissolved in DMSO and serially diluted. The reaction was stopped by the addition of 0.2 N HCl and the product was captured using anti-mouse YSi SPA beads (GE) conjugated to an anti-DHEA monoclonal antibody (Abcam). Signal intensity determined by a Packard Top Count was used to calculate percent inhibition and IC50 values.
Cyp17 Hydroxylase Assay
E. coli was transformed to express active human CYP17 and membranes prepared from the transformed E. coli were used as the source of enzyme. The reaction was carried out in a 50 μL, final volume containing 200 nM hCYP17 membranes, 25 μM Pregnenolone (Sigma), 7 mM NADPH (CalBiochem), 1 μM cytochrome P450 reductase (Invitrogen), and 50 mM sodium phosphate buffer, pH 7.3. The IC50 determination of compounds dissolved in 100% DMSO was done by serial dilution into the assay buffer to a final concentration of 0.2% DMSO. The reaction was incubated at 37° C. for 120 minutes and stopped by the addition of 200 μL of 0.02N HCl in acetonitrile. Samples were then spun at 750000 g and 200 μL of the supernatant was transferred to a clean tube for analysis. The product of the reaction, 17 alpha pregnenolone, was measured via LC/MS.
Cyp17 HEK293 Cell Based Assay
HEK293 cells were stably transfected with human Cyp17 and individual clones analyzed for Cyp17 enzymatic activity via LC/MS. A single clone showing robust activity was selected and scaled up. Cells were seeded in 96 well plates and a serial dilution of compounds dissolved in DMSO was added to the cells. Following an incubation of 4 hours, reactions were neutralized by the addition of 200 ul of acetonitrile containing 0.5 uM pregnenolone as tracer. Plates were spun down at 2K for 15 minutes and supernatants transferred to siliconized 96 well plates. The end product of the reaction DHEA was analyzed via LC/MS.
1-Day Cyno PK/PD Study Protocol
Animals: All procedures involving animals and their care were conducted in conformity with the guidelines that are in compliance with the Bristol-Myers Squibb Institutional Animal Care and Use Committee. Fully mature male cynomolgus monkeys (>4 yrs of age; 5-6 kg) were from an in-house colony. All the monkeys used had chronically implanted femoral vein access ports. For oral studies, all animals were fasted overnight prior to dosing and were fed 4 hr after dosing. All animals had free access to water and were conscious throughout the study.
Drug: For all oral pharmacokinetic studies in cynomolgus monkeys, the tested compound was formulated in polyethylene glycol (PEG 400): water (80:20, v:v) at concentrations of 1-5 mg/mL.
Drug Treatment: The tested compound was administered by oral gavage to cynomolgus monkeys.
Sampling: Blood samples were collected from the femoral port, at 15, 30, and 45 min, and 1, 2, 4, 6, 8, 12, 24, 30, and 48 hr after oral administration. All blood samples were collected into syringes containing sodium heparin. The plasma fraction was immediately separated by centrifugation (14,000 rpm, 10 min, 4° C.), frozen on dry ice, and stored at −20° C. until the samples were analyzed.
Analysis of Tested Compound: Plasma samples were thawed and treated with two volumes of acetonitrile containing internal standard. After centrifugation to remove precipitated proteins, an aliquot of supernatant was analyzed by LC/MS/MS.
Analysis of Steroids: Plasma samples were thawed, and assayed in accordance with package insert instructions for the following kits: Coat-A-Count total testosterone solid phase RIA kit, Coat-A-Count total progesterone solid phase RIA kit, and Coat-A-Count total cortisol solid phase RIA kit (Diagnostic Product Corp, Siemens Healthcare Diagnostics, Deerfield, Ill.).
FIG. 1 shows the results of a 1-day PK/PD study in NHP cynomolgus monkeys with Example 217. Example 217 was formulated in 80% PEG-400/water at a volume of 1 mL/Kg of monkey and a dose of 5 mg/Kg. The formulation was then administered orally at time=0 and blood samples were taken over a 24 hour period to monitor for drug exposure and testosterone levels. FIG. 1 shows that testosterone levels are reduced after single oral dose of Example 217, consistent with an inhibitor of CYP17 lyase.
