Description

Related Applications

[0001] This application claims the benefit of U.S. Provisional Application No. 60/021,997, filed June 27, 1996.

Field of the Invention

[0002] This invention relates to non-steroidal compounds that are modulators (i.e. agonists and antagonists) of androgen receptors, and to methods for the making and use of such compounds.

Background of the Invention

[0003] Intracellular receptors (IRs) form a class of structurally-related genetic regulators scientists have named "ligand dependent transcription factors." R.M. Evans, 240 Science, 889 (1988). Steroid receptors are a recognized subset of the IRs, including the progesterone receptor (PR), androgen receptor (AR), estrogen receptor (ER), glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Regulation of a gene by such factors requires both the IR itself and a corresponding ligand which has the ability to selectively bind to the IR in a way that affects gene transcription.

[0004] Ligands to the IRs can include low molecular weight native molecules, such as the hormones progesterone, estrogen and testosterone, as well as synthetic derivative compounds such as medroxyprogesterone acetate, diethylstilbesterol and 19-nortestosterone. These ligands, when present in the fluid surrounding a cell, pass through the outer cell membrane by passive diffusion and bind to specific IR proteins to create a ligand/receptor complex. This complex then translocates to the cell's nucleus, where it binds to a specific gene or genes present in the cell's DNA. Once bound to DNA, the complex modulates the production of the protein encoded by that gene. In this regard, a compound which binds an IR and mimics the effect of the native ligand is referred to as an "agonist", while a compound that inhibits the effect of the native ligand is called an "antagonist."

[0005] Ligands to the steroid receptors are known to play an important role in health of both women and men. For example, the native female ligand, progesterone, as well as synthetic analogues, such as norgestrel (18-homonorethisterone) and norethisterone (17α-ethinyl-19-nortestosterone), are used in birth control formulations, typically in combination with the female hormone estrogen or synthetic estrogen analogues. as effective modulators of both PR and ER. On the other hand, antagonists to PR are potentially useful in treating chronic disorders, such as certain hormone dependent cancers of the breast, ovaries, and uterus, and in treating non-malignant conditions such as uterine fibroids and endometriosis, a leading cause of infertility in women. Similarly, AR antagonists, such as cyproterone acetate and flutamide have proved useful in the treatment of prostatic hyperplasia and cancer of the prostate.

[0006] The effectiveness of known modulators of steroid receptors is often tempered by their undesired side-effect profile, particularly during long-term administration. For example, the effectiveness of progesterone and estrogen agonists, such as norgestrel and diethylstilbesterol respectively, as female birth control agents must be weighed against the increased risk of breast cancer and heart disease to women taking such agents. Similarly, the progesterone antagonist, mifepristone (RU486), if administered for chronic indications, such as uterine fibroids, endometriosis and certain hormone-dependent cancers, could lead to homeostatic imbalances in a patient due to its inherent cross-reactivity as a GR antagonist. Accordingly, identification of compounds which have good specificity for one or more steroid receptors, but which have reduced or no cross-reactivity for other steroid or intracellular receptors, would be of significant value in the treatment of male and female hormone responsive diseases.

[0007] A group of quinoline analogs having an adjacent polynucleic ring system of the indene or fluorene series or an adjacent polynucleic heterocyclic ring system with substituents having a nonionic character have been described as photoconductive reducing agents, stabilizers, laser dyes and antioxidants. See e.g., U.S. Patent Nos. 3,798,031; 3,830,647; 3,832,171; 3,928,686; 3,979,394; 4,943,502 and 5.147.844 as well as Soviet Patent No. 555,119; R.L. Atkins and D.E. Bliss, "Substituted Coumarins and Azacoumarins: Synthesis and Fluorescent Properties", 43 J. Org. Chem., 1975 (1978), E.R. Bissell et al., "Synthesis and Chemistry of 7-Amino-4-(trifluoromethyl)coumarin and Its Amino Acid and Peptide Derivatives", 45 J. Org. Chem., 2283 (1980) and G.N. Gromova and K.B. Piotrovskii, "Relative Volatility of Stabilizers for Polymer Materials," 43 Khim. Prom-st., 97 (Moscow, 1967). Further, a group of quinoline derivatives was recently described as modulators of steroid receptors. WO 96/19458, published June 27, 1996.

[0008] WO-A-95/11215 describes C-benzyl substituted cyclohexanes, cyclopentanes, tetrahydropyrans and piperidines which may also have a double bond in the carbocyclic or heterocyclic ring. The compounds are useful as androgen receptor antagonists and can be used to treat patients requiring androgen replacement therapy.

[0009] Furthermore, WO-A-91/00732 discloses steroid derivatives which may be used as androgen synthesis inhibitors. Finally, the Journal of the American Chemical Society, Vol. 98, pages 5012-14 (1976) describes a tetracyclic compound which differs from a compound of formula (V) of claim 1 in that the peri fused ring contains a CH₂-O linking group instead of a C=O-O linking group. However, this compound is disclosed as an antibiotic and no androgen receptor activity is suggested.

[0029] Compounds of the present invention, comprising classes of heterocyclic nitrogen compounds and their derivatives. that can be obtained by routine chemical synthesis by those skilled in the art, e.g., by modification of the heterocyclic nitrogen compounds disclosed or by a total synthesis approach.

[0030] The sequence of steps for several general schemes to synthesize the compounds of the present invention are shown below, In each of the Schemes the R groups (e.g., R¹, R², etc.) correspond to the specific substitution patterns noted in the Examples. However, it will be understood by those skilled in the art that other functionalities disclosed herein at the indicated positions of compounds of formulas I through V also comprise potential substituents for the analogous positions on the structures within the Schemes.

[0031] The process of Scheme I begins with an acetylide addition to 5-chloro-2-pentanone (Compound 1) with, for example, ethynylmagnesium bromide. The alcohol is then esterified to the corresponding acetate (Compound 2) with, for example, acetic anhydride and 4-dimethylaminopyridine in pyridine. A tandem propargylation/alkylation of Compound 2 with aniline (Compound 3) in the presence of a copper (I) or copper (II) salt, such as copper(I) chloride, and a base, such as triethylamine, affords Compound 4. See Y. Imada. M. Yuasa, I. Nakamura and S.-I. Murahashi, "Copper(I)-Catalyzed Amination of Propargyl Esters. Selective Synthesis of Propargylamines, 1-Alken-3-ylamines, and (Z)-Allylamines.", J. Org. Chem. 1994, 59, 2282, the disclosure of which is herein incorporated by reference. Cyclization of Compound 4 occurs in the presence of a copper catalyst, such as copper(I) chloride, to afford Compound 5. See N. R. Easton and D. R. Cassady, "A Novel Synthesis of Quinolines and Dihydroquinolines." J. Org. Chem. 1962, 27, 4713, and N. R. Easton and G. F. Hennion, "Metal Catalyst Process for Converting α-Amino-Acetylenes to Dihydroquinoline", U. S. Patent 3,331846 (1967), the disclosure of which is herein incorporated by reference.

[0032] Reduction of the olefin with, for example, hydrogen over a metal catalyst such as palladium on carbon, affords Compound 6. Nitration of Compound 6 with, for example, fuming nitric acid, followed by reduction of the nitro group with, for example, hydrogen over a metal catalyst such as palladium on carbon, affords the desired diamine (Compound 7A) along with small amounts of a regioisomer, which was separated (Compound 7B). A Knorr cyclization of Compound 7A with a β-keto ester or hydrated derivative, effected by, for example, zinc chloride, affords a compound of structure 8. See: E. T. McBee, O. R. Pierce, H. W. Kilbourne, and E. R. Wilson, "The Preparation and Reactions of Fluorine-containing Acetoacetic Esters." J. Am. Chem. Soc. 1953, 75, 3152, the disclosure of which is herein incorporated by reference, for the preparation of the fluorinated acetoacetate reagents. A compound of structure 8 may be further transformed into a compound of structure 9 by treatment of structure 8 with a base, such as sodium hydride, and an alkylating agent, such as methyl iodide.

[0033] The process of Scheme II begins with the nitration of a tricyclic tetrahydroquinoline such as julolidine, Compound 10, followed by reduction of the nitro group to afford an aniline such as Compound 11. Treatment of Compound 11 with a β-keto ester such as ethyl 4,4,4-trifluoroacetoacetate and a Lewis acid such as zinc chloride (the Knorr reaction) affords a tetracyclic quinolinone such as Compound 12. The quinoline may be further functionalized by alkytation of the amide nitrogen by, for example, treatment with a base such as sodium hydride followed by the addition of an alkylating agent such as iodomethane, to afford a compound like Compound 13.

[0034] The process of Scheme III begins with an esterification of a propargyl alcohol (structure 14) with, for example, acetic anhydride and 4-dimethylaminopyridine in pyridine (structure 15). Alkylation of the acetate with aniline (Compound 3) in the presence of a copper(I) or copper(II) salt, such as copper(I) chloride, and a base. such as triethylamine affords a compound of structure 16. Cyclization of structure 16 occurs in the presence of a copper catalyst, such as copper(I) chloride, to afford a compound of structure 17.

[0035] Reduction of the olefin, with for example, hydrogen over a metal catalyst, such as palladium on carbon, affords a compound of structure 18. Nitration of a compound of structure 18 with, for example, fuming nitric acid, followed by reduction of the nitro group, with, for example hydrogen over a metal catalyst such as palladium on carbon, affords a compound of structure 19. A Knorr cyclization of a compound of structure 19 with a β-keto ester or hydrated derivative, effected by, for example, zinc chloride, affords a compound of structure 20. A compound of structure 20 may be further transformed into a compound of structure 21 by treatment of structure 20 with a base, such as sodium hydride, and an alkylating agent, such as methyl iodide. A compound of structure 21 may be further transformed by reductive alkylation with, for example, paraformaldehyde and sodium borohydride in acetic acid, to afford a compound of structure 22.

[0036] The process of Scheme IV begins with the acylation of a 3-nitroaniline (structure 23) with an acylating agent, for example, di-tert-butyl dicarbonate or trimethylacetyl chloride, to afford a compound of structure 24. Reduction of the nitro group with, for example, hydrogen over a metal catalyst such as palladium on carbon, affords the corresponding aniline (structure 25). Treatment of a compound of structure 25 with acetone and a catalyst such as iodine affords a compound of structure 26, in a process known as the Skraup cyclization. See R.H.F. Manske and M. Kulka, "The Skraup Synthesis of Quinolines", Organic Reactions 1953, 7, 59, the disclosure of which is herein incorporated by reference. Deprotection by either acid or base, followed by treatment of the corresponding aniline with a β-keto ester (or corresponding hydrate) in the presence of a Lewis acid such as zinc chloride, affords as the major product a compound of structure 27. The cyclization of an aniline as described above is known as a Knorr cylization. See G. Jones, "Pyridines and their Benzo Derivatives: (v) Synthesis". In Comprehensive Heterocyclic Chemistry, Katritzky, A. R.; Rees, C. W., eds. Pergamon, New York, 1984. Vol. 2, chap. 2.08, pp 421-426. In turn, the quinolinone nitrogen may be alkylated by, for example, treatment with sodium hydride followed by iodomethane, to afford a compound of structure 28. Likewise, the quinoline nitrogen may be alkylated by, for example, treatment with paraformaldehdye and sodium cyano borohydride, to afford a compound of structure 29.

[0037] The process of Scheme V involves the reduction of the C(3)-C(4) olefin of a compound of structure 27 to afford a tetrahydroquinoline of structure 30, which may be accomplished by a hydrogenation with, for example, hydrogen over palladium on carbon, or by a cationic process with, for example, trifluoroacetic acid and triethylsilane.

[0038] The process of Scheme VI involves the oxidation of both the quinoline nitrogen and C(10) alkyl group of a compound of structure 30, followed cyclization and loss of water to afford a compound of structure 31. This may be effected by treatment of a compound of structure 30 (R¹ = alkyl, preferably methyl) with an oxygen transfer agent or combination of oxygen transfer agents, such as hydrogen peroxide in the presence of peracetic acid, to afford a compound of structure 31.

[0039] The process of Scheme VII involves the alkyation of one or both of the nitrogen atoms of a compound of structure 30. The quinolinone nitrogen may be selectively alkylated by treatment with a base, such as sodium hydride, followed by an alkylating agent, such as methyl iodide, to afford a compond of structure 32. The quinoline nitrogen may be selectively alkylated by a reductive alkylation procedure using, for example, paraformaldehdye in the presence of sodium cyano borohydride and acetic acid, to afford a compound of structure 33. Subsequently, the quinoline nitrogen of a compound of structure 32 may be reductively alkylated in a manner similar to the conversion of 30 to 33, or the quinolinone nitrogen of a compound of structure 33 may be alkylated in a manner similar to the conversion of 30 to 32. Either of these processes will afford a compound of structure 34.

[0040] The process of Scheme VIII begins with the oxidation of the quinoline nitrogen atom of a compound of structure 20 with an oxygen transfer agent or mixture of oxygen transfer agents, for example, hydrogen peroxide in the presence of peracetic acid, to afford a compound of structure 35. The quinolinone nitrogen may subsequently be alkylated by, for example, treatment with sodium hydride and methyl iodide, to afford a compound of structure 36.

[0041] The process of Scheme IX begins with the reaction of an aniline (structure 37) with an unsaturated acid, for example acrylic acid, followed by a cyclization reaction mediated by, for example, polyphosphoric acid to afford a 4-quinolinone. The nitrogen atom is then protected by treatment with a base, for example, 4-dimethylaminopyridine, followed by the addition of an acylating agent such as di-tert-butyldicarbonate, to afford a compound of structure 38. Addition of an organomagnesium or organolithium reagent, with, for example, ethyl magnesium bromide, affords an alcohol. Reduction of the alcohol with, for example hydrogen over palladium on carbon, followed by deprotection of the nitrogen atom, affords a compound of structure 39. Nitration of a compound of structure 39 by the action of nitric acid in the presence of, for example, sulfuric acid, followed by reduction of the nitro group with, for example, hydrogen over palladium on carbon, affords a 7-amino-1,2,3,4-tetrahydroquinoline of structure 40. A Knorr cyclization with a β-keto ester effected by, for example, zinc chloride, affords a compound of structure 41. A compound of structure 41 may be further transformed into a compounds of structure 42 by acylation of the quinoline nitrogen, which may be accomplished in one of 2 ways. Treatment of structure 41 with an acid chloride, for example, acetyl chloride, followed by treatment with a base, for example, potassium carbonate, to afford a compound of structure 42. Alternatively, treatment of structure 41 may be treated with an anhydride, for example, trifluoroacetic anhyride, likewise to afford a compound of structure 42.

[0042] The process of Scheme X involves the treatment of structure 43 with, for example, nitric acid in the presence of, for example, sulfuric acid, to afford compounds of structure 44, 45 and 46.

[0043] The compounds of the present invention also include racemates, stereoisomers and mixtures of said compounds, including isotopically-labeled and radio-labeled compounds. Such isomers can be isolated by standard resolution techniques, including fractional crystallization and chiral column chromatography.

[0044] As noted above, any of the steroid modulator compounds of the present invention can be combined in a mixture with a pharmaceutically acceptable carrier to provide pharmaceutical compositions useful for treating the biological conditions or disorders noted herein in mammalian, and more preferably, in human patients. The particular carrier employed in these pharmaceutical compositions may take a wide variety of forms depending upon the type of administration desired, e.g., intravenous, oral, topical, suppository or parenteral.

[0045] In preparing the compositions in oral liquid dosage forms (e.g., suspensions, elixirs and solutions), typical pharmaceutical media, such as water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like can be employed. Similarly, when preparing oral solid dosage forms (e.g., powders, tablets and capsules), carriers such as starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like will be employed. Due to their ease of administration, tablets and capsules represent the most advantageous oral dosage form for the pharmaceutical compositions of the present invention.

[0046] For parenteral administration, the carrier will typically comprise sterile water, although other ingredients that aid in solubility or serve as preservatives, may also be included. Furthermore, injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like will be employed.

[0047] For topical administration, the compounds of the present invention may be formulated using bland, moisturizing bases, such as ointments or creams. Examples of suitable ointment bases are petrolatum, petrolatum plus volatile silicones, lanolin, and water in oil emulsions such as Eucerin™ (Beiersdorf). Examples of suitable cream bases are Nivea™ Cream (Beiersdorf), cold cream (USP), Purpose Cream™ (Johnson & Johnson), hydrophilic ointment (USP), and Lubriderm™ (Warner-Lambert).

[0048] The pharmaceutical compositions and compounds of the present invention will generally be administered in the form of a dosage unit (e.g., tablet, capsule etc.) at from about 1 µg/kg of body weight to about 500 mg/kg of body weight, more preferably from about 10 µg/kg to about 250 mg/kg, and most preferably from about 20 µg/kg to about 100 mg/kg. As recognized by those skilled in the art, the particular quantity of pharmaceutical composition according to the present invention administered to a patient will depend upon a number of factors, including, without limitation, the biological activity desired, the condition of the patient, and tolerance for the drug.

[0049] The compounds of this invention also have utility when radio- or isotopically-labeled as ligands for use in assays to determine the presence of AR in a cell background or extract. They are particularly useful due to their ability to selectively activate androgen receptors, and can therefore be used to determine the presence of such receptors in the presence of other steroid receptors or related intracellular receptors.

[0050] Due to the selective specificity of the compounds of this invention for steroid receptors, these compounds can be used to purify samples of steroid receptors in vitro. Such purification can be carried out by mixing samples containing steroid receptors with one or more of the compounds of the present invention so that the compounds bind to the receptors of choice, and then separating out the bound ligand/receptor combination by separation techniques which are known to those of skill in the art. These techniques include column separation, filtration, centrifugation, tagging and physical separation, and antibody complexing, among others.

[0051] The compounds and pharmaceutical compositions of the present invention can advantageously be used in the treatment of the diseases and conditions described herein. In this regard, the compounds and compositions of the present invention will prove particularly useful as modulators of male sex steroid-dependent diseases and conditions such as the treatment of acne, male-pattern baldness, male hormone replacement therapy, wasting diseases, hirsutism, stimulation of hematopoiesis, hypogonadism, prostatic hyperplasia, various hormone-dependent cancers, including. without limitation, prostate and breast cancer and as anabolic agents.

[0052] The compounds and pharmaceutical compositions of the present invention possess a number of advantages over previously identified steroidal and non-steroidal compounds.

[0053] Furthermore, the compounds and pharmaceutical compositions of the present invention possess a number of advantages over previously identified steroid modulator compounds. For example, the compounds are extremely potent activators AR, preferably displaying 50% maximal activation of AR at a concentration of less than 100 nM, more preferably at a concentration of less than 50 nM, more preferably yet at a concentration of less than 20 nM, and most preferably at a concentration of 10 nM or less. Also, the selective compounds of the present invention generally do not display undesired cross-reactivity with other steroid receptors, as is seen with the compound mifepristone (RU486; Roussel Uclaf), a known PR antagonist that displays an undesirable cross reactivity on GR and AR, thereby limiting its use in long-term, chronic administration. In addition, the compounds of the present invention, as small organic molecules, are easier to synthesize, provide greater stability and can be more easily administered in oral dosage forms than other known steroidal compounds.

[0054] The invention will be further illustrated by reference to the following non-limiting Examples.

Steroid Receptor Activity

[0104] Utilizing the "cis-trans" or "co-transfection" assay described by Evans et aL, Science, 240:889-95 (May 13, 1988), the disclosure of which is herein incorporated by reference, the compounds of the present invention were tested and found to have strong, specific activity as both agonists, partial agonists and antagonists of AR. This assay is described in further detail in U.S. Patent Nos. 4,981,784 and 5,071,773, the disclosures of which are incorporated herein by reference.

[0105] The co-transfection assay provides a method for identifying functional agonists and partial agonists which mimic, or antagonists which inhibit, the effect of native hormones, and quantifying their activity for responsive IR proteins. In this regard, the co-transfection assay mimics an in vivo system in the laboratory. Importantly, activity in the co-transfection assay correlates very well with known in vivo activity, such that the co-transfection assay functions as a qualitative and quantitative predictor of a tested compounds in vivo pharmacology. See, e.g., T. Berger et al. 41 J. Steroid Biochem. Molec. Biol. 773 (1992), the disclosure of which is herein incorporated by reference.

[0106] In the co-transfection assay, a cloned cDNA for an IR (e.g., human PR, AR or OR) under the control of a constitutive promoter (e.g., the SV 40 promoter) is introduced by transfection (a procedure to induce cells to take up foreign genes) into a background cell substantially devoid of endogenous IRs. This introduced gene directs the recipient cells to make the IR protein of interest. A second gene is also introduced (co-transfected) into the same cells in conjunction with the IR gene. This second gene, comprising the cDNA for a reporter protein, such as firefly luciferase (LUC), controlled by an appropriate hormone responsive promoter containing a hormone response element (HRE). This reporter plasmid functions as a reporter for the transcription-modulating activity of the target IR. Thus, the reporter acts as a surrogate for the products (mRNA then protein) normally expressed by a gene under control of the target receptor and its native hormone.

[0107] The co-transfection assay can detect small molecule agonists or antagonists of target IRs. Exposing the transfected cells to an agonist ligand compound increases reporter activity in the transfected cells. This activity can be conveniently measured, e.g., by increasing luciferase production, which reflects compound-dependent, IR-mediated increases in reporter transcription. To detect antagonists, the co-transfection assay is carried out in the presence of a constant concentration of an agonist to the target IR (e.g., progesterone for PR) known to induce a defined reporter signal. Increasing concentrations of a suspected antagonist will decrease the reporter signal (e.g., luciferase production). The co-transfection assay is therefore useful to detect both agonists and antagonists of specific IRs. Furthermore, it determines not only whether a compound interacts with a particular IR, but whether this interaction mimics (agonizes) or blocks (antagonizes) the effects of the native regulatory molecules on target gene expression, as well as the specificity and strength of this interaction.

[0108] The activity of selected steroid receptor modulator compounds of the present invention were evaluated utilizing the co-transfection assay, and in standard IR binding assays, according to the following illustrative Examples.

EXAMPLE 29

Co-transfection assay

[0109] CV-1 cells (African green monkey kidney fibroblasts) were cultured in the presence of Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% charcoal resinstripped fetal bovine serum then transferred to 96-well microtiter plates one day prior to transfection.

[0110] To determine AR agonist and antagonist activity of the compounds of the present invention, the CV- 1 cells were transiently transfected by calcium phosphate coprecipitation according to the procedure of Berger et al., 41 J. Steroid Biochem. Mol. Biol., 733 (1992) with the following plasmids: pShAR (5 ng/well), MTV-LUC reporter (100 ng/well), pRS-β-Gal (50 ng/well) and filler DNA (pGEM; 45 ng/well). The receptor plasmid, pRShAR, contains the human AR under constitutive control of the SV-40 promoter, as more fully described in J.A. Simental et al., "Transcriptional activation and nuclear targeting signals of the human androgen receptor", 266 J. Biol. Chem., 510 (1991).

[0111] The reporter plasmid, MTV-LUC, contains the cDNA for firefly luciferase (LUC) under control of the mouse mammary tumor virus (MTV) long terminal repeat, a conditional promoter containing an androgen response element. See e.g, Berger et al. supra. In addition, pRS-β-Gal, coding for constitutive expression of E. colβ-galactosidase (β-Gal), was included as an internal control for evaluation of transfection efficiency and compound toxicity.

[0112] Six hours after transfection, media was removed and the cells were washed with phosphate-buffered saline (PBS). Media containing reference compounds (i.e. progesterone as a PR agonist, mifepristone ((11beta, 17beta)-11-[4-(dimethylamino)phenyl)-I7-hydroxy-17-(1-propynyl)estra-4,9-dien-3-one: RU486; Roussel Uclaf) as a PR antagonist; dihydrotestosterone (DHT; Sigma Chemical) as an AR agonist and 2-OH-flutamide (the active metabolite of 2-methyl-N-[4-nitro-3-(trifluoromethyl)phenyl]pronanamide; Schering-Plough) as an AR antagonist; estradiol (Sigma) as an ER agonist and ICI 164,384 (N-butyl-3,17-dihydroxy-N-methyl-(7-alpha, 17-beta)-estra-1,3,5(10)-triene-7-undecanamide; ICI Americas) as an ER antagonist: dexamethasone (Sigma) as a GR agonist and RU486 as a GR antagonist; and aldosterone (Sigma) as a MR agonist and spironolactone ((7-alpha-[acetylthio]-17-alpha-hydroxy-3-oxopregn-4-ene-21-carboxylic acid gamma-lactone; Sigma) as an MR antagonist) and/or the modulator compounds of the present invention in concentrations ranging from 10^-12 to 10^-5 M were added to the cells. Three to four replicates were used for each sample. Transfections and subsequent procedures were performed on a Biomek 1000 automated laboratory work station.

[0113] After 40 hours, the cells were washed with PBS, lysed with a Triton X-100-based buffer and assayed for LUC and β-Gal activities using a luminometer or spectrophotometer, respectively. For each replicate, the normalized response (NR) was calculated as:
   LUC response/β-Gal rate
where β-Gal rate = β-Gal•1x10^-5/β-Gal incubation time.

[0114] The mean and standard error of the mean (SEM) of the NR were calculated. Data was plotted as the response of the compound compared to the reference compounds over the range of the dose-response curve. For agonist experiments, the effective concentration that produced 50% of the maximum response (EC₅₀) was quantified. Agonist efficacy was a function (%) of LUC expression relative to the maximum LUC production by the reference agonist for PR, AR, ER, GR or MR. Antagonist activity was determined by testing the amount of LUC expression in the presence of a fixed amount of DHT as an AR agonist and progesterone as a PR agonist at the EC₅₀ concentration. The concentration of test compound that inhibited 50% of LUC expression induced by the reference agonist was quantified (IC₅₀). In addition, the efficacy of antagonists was determined as a function (%) of maximal inhibition.

IR Binding assay

[0115] AR Binding: For the whole cell binding assay, COS-1 cells in 96-well microtiter plates containing DMEM-10% FBS were transfected as described above with the following plasmid DNA: pRShAR (2 ng/well), pRS-β-Gal (50 ng/well) and pGEM (48 ng/well). Six hours after transfection, media was removed, the cells were washed with PBS and fresh media was added. The next day, the media was changed to DMEM-serum free to remove any endogenous ligand that might be complexed with the receptor in the cells.

[0116] After 24 hours in serum-free media, either a saturation analysis to determine the Kd for tritiated dihydrotestosterone (³H-DHT) on human AR or a competitive binding assay to evaluate the ability of test compounds to compete with ³H-DHT for AR was performed. For the saturation analysis, media (DMEM-0.2% CA-FBS) containing ³H-DHT (in concentrations ranging from 12 nM to 0.24 nM) in the absence (total binding) or presence (non-specific binding) of a 100-fold molar excess of unlabeled DHT were added to the cells. For the competitive binding assay, media containing 1 nM ³H-DHT and test compounds in concentrations ranging from 10^-10 to 10^-6 M were added to the cells. Three replicates were used for each sample. After three hours at 37°C, an aliquot of the total binding media at each concentration of ³H-DHT was removed to estimate the amount of free ³H-DHT. The remaining media was removed, the cells were washed three times with PBS to remove unbound ligand, and cells were lysed with a Triton X-100-based buffer. The lysates were assayed for amount of bound ³H-DHT and β-Gal activity using a scintillation counter or spectrophotometer, respectively.

[0117] For the saturation analyses, the difference between the total binding and the nonspecific binding, normalized by the β-Gal rate, was defined as specific binding. The specific binding was evaluated by Scatchard analysis to determine the Kd for ³H-DHT. See e.g., D. Rodbard, "Mathematics and statistics of ligand assays: an illustrated guide" In: J. Langon and J.J. Clapp, eds., Ligand Assay, Masson Publishing U.S.A., Inc., New York, pp. 45-99, (1981), the disclosure of which is herein incorporated by reference. For the competition studies, the data was plotted as the amount of ³H-DHT (% of control in the absence of test compound) remaining over the range of the dose-response curve for a given compound. The concentration of test compound that inhibited 50% of the amount of ³H-DHT bound in the absence of competing ligand was quantified (IC₅₀) after log-logit transformation. The K_i values were determined by application of the Cheng-Prusoff equation to the IC₅₀ values. where:

[0118] After correcting for non-specific binding, IC₅₀ values were determined. The IC₅₀ value is defined as the concentration of competing ligand needed to reduce specific binding by 50%. The IC₅₀ value was determined graphically from a log-logit plot of the data. The K_i values were determined by application of the Cheng-Prusoff equivuation to the IC₅₀ values, the labeled ligand concentration and the Kd of the labeled ligand.

[0119] The agonist, antagonist and binding activity assay results of selected androgen receptor modulator compounds of present invention and the standard reference compounds on AR, as well as the cross-reactivity of selected compounds on the PR, ER, MR and GR receptors, are shown in Tables 1-2 below. Efficacy is reported as the percent maximal response observed for each compound relative to the reference agonist and antagonist compounds indicated above. Also reported in Tables 1-2 for each compound is its antagonist potency or IC₅₀ (which is the concentration (nM), required to reduce the maximal response by 50%), its agonist potency or EC₅₀ (nM).

[0120] As can be seen in the Tables, Compounds 109 and 112 are highly selective AR antagonists, while Compounds 105, 111 and 113 are mixed AR agonists/antagonists. Importantly, these AR Compounds show very little or no cross reactivity on other sex steroid receptors. In contrast, the known PR antagonist. RU486, shows strong cross reactivity on both GR and AR, showing essentially equivual potency as both a PR and GR antagonist, and strong activity as an AR antagonist.

EXAMPLE 30

Mouse Renal Ornithine Decarboxylase (ODC) Activity as an in vivo assay for determining the activity of AR Modulators

[0121] Ornithine Decarboxylase (ODC) is the first rate-limiting enzyme for polyamine synthesis and catalyzes conversion of L-ornithine to putrescine, releasing CO₂. It is a constitutive enzyme present in all cells and tissues. ODC concentration is very low in quiescent cells; but. as part of a growth response, it increases many-fold within hours of exposure to trophic stimuli, such as hormones, drugs, and growth factors. See G. Scalabrino, et al. "Polyamines and Mammalian Hormones", Mol. Cell. Endocrinol. 77:1-35, 1991.

[0122] This enzyme in the mouse kidney is specifically stimulated by androgens. but not by estrogen, progesterone or glucocorticoids. See O. A. Janne, et al. "Omithine Decarboxylase mRNA in Mouse Kidney: A Low Abundancy Gene Product Regulated by Androgens with Rapid Kinetics", Ann New York Academy of Sciences 438:72-84, 1984 and J. F. Catterall, et al. "Regulation of Gene Expression by Androgens in Murine Kidney", Rec. Prog. Hor. Res. 42:71-109, 1986. Androgen induction of ODC activity and gene expression occurs rapidly, becoming maximally stimulated within 24 hr of a single dose of testosterone. Therefore, it is was used as an acute assay to determine the androgen specific response of compounds, including compounds of the present invention, in vivo.

[0123] In this assay, castrated male ICR mice (∼ 30 g, 5 - 6 week-old) were grouped in fours and treated for I or 3 days as follows:

1) Control vehicle

2) Testosterone propionate (TP) (0.01-1.0 mg/mouse or 0.3-30 mg/kg, s.c.)

3) TP (3 mg/kg, s.c.) plus a reference compound or a compound of the present invention (30-90 mg/kg, orally/s.c.) to demonstrate antagonist activity, or

4) A compound of the present invention alone (30-90 mg/kg. orally/s.c.) to demonstrate AR agonist activity

[0124] The animals are sacrificed 24 hr after last dosing, and the pair of kidneys were collected and homogenized. The homogenates were centrifuged to get supernatant (cytosol), which was incubated with [³H]ornithine for 1 hour. The activity of this enzyme was measured by a titrimetric analysis of the rate of [³H]putrescine production. Results were expressed as femtomoles of [³H]putrescine formed per mg of protein per hour. R. Djurhuus "Omithine Decarboxylase (EC4.1.1.17) Assay Based Upon the Retention of Putrescine by a Strong Cation-Exchange Paper". Anal. Biochem. 113:352-355,1981.

AR agonist mode:

[0125] Testosterone propionate (TP) induced the ODC activity in a dose-dependent manner within the doses of 0.01 to 1.0 mg/mouse. Even at the highest dose used (1 mg/mouse), the induced ODC activity was not saturated, which was a 700-fold increase compared to castrated controls. Testosterone also showed similar stimulatory effects on ODC activities with less potency compared to TP (See Table 3). However, estradiol (0.02 mg/mouse) or progesterone (1 mg/mouse) did not show any stimulatory activity on this enzyme. The increase in ODC activity was accompanied by parallel, but lesser, changes in seminal vesicle weights. For example, TP (1.0 mg/mouse/day) resulted in a 700-fold increase in ODC activity, whereas increases in seminal vesicle weights were 4- to 5-fold.

AR antagonist mode:

[0126] When testosterone propionate (0.1 mg/mouse) was used to induce the enzyme activity, the reference AR antagonists, flutamide, casodex and cyproterone acetate, inhibited this induction. Compounds of the present invention demonstrated AR antagonist activity in this assay model as shown in Table 4.
