## Background
RELATED APPLICATIONS
Priority is claimed to U.S. Provisional Patent Application No. 60/552,690, filed Mar. 12, 2004, entitled “ANDROGEN RECEPTOR MODULATOR COMPOUNDS AND METHODS.” This application is a divisional of U.S. application Ser. No. 10/590,119, filed Jun. 11, 2007, entitled “ANDROGEN RECEPTOR MODULATOR COMPOUNDS AND METHODS”, which is a National Stage of International Application No. PCT/US2005/007867, filed 11 Mar. 2005, entitled “ANDROGEN RECEPTOR MODULATOR COMPOUNDS AND METHODS.”
Where permitted, the disclosures of the above-referenced applications are incorporated herein by reference in their entireties.


FIELD
Provided herein are compounds that bind to androgen receptors and/or modulate activity of androgen receptors, and to methods for making and using such compounds. Also provided are compositions containing such compounds and methods for making and using such compositions.
BACKGROUND
Certain intracellular receptors (IRs) have been shown to regulate transcription of certain genes. See e.g., R. M. Evans, Science, 240, 889 (1988). Certain of such IRs are steroid receptors, such as androgen receptors, glucocorticoid receptors, estrogen receptors, mineralocorticoid receptors, and progesterone receptors. Gene regulation by such receptors typically involves binding of an IR by a ligand.
In certain instances, a ligand binds to an IR, forming a receptor/ligand complex. Such a receptor/ligand complex may then translocate to the nucleus of a cell, where it may bind to the DNA of one or more gene regulatory regions. Once bound to the DNA of a particular gene regulatory region, a receptor/ligand complex may modulate the production of the protein encoded by that particular gene. In certain instances, an androgen receptor/ligand complex regulates expression of certain proteins. In certain instances, an androgen receptor/ligand complex may interact directly with the DNA of a particular gene regulatory region. In certain instances, an androgen receptor/ligand complex may interact with other transcription factors, such as activator protein-1 (AP-1) or nuclear factor κB (NFκB). In certain instances, such interactions result in modulation of transcriptional activation.
SUMMARY
Compounds for use in compositions and methods for modulating the activity of androgen receptor are provided. In one embodiment, the compounds provided herein are agonists of androgen receptor. In another embodiment, the compounds provided herein are antagonists of androgen receptor.

It is to be understood that the compounds provided herein can contain chiral centers. Such chiral centers can be of either the (R) or (S) configuration, or can be a mixture thereof. Thus, the compounds provided herein can be enantiomerically pure, or be stereoisomeric or diastereomeric mixtures.
As used herein, substantially pure means sufficiently homogeneous to appear free of readily detectable impurities as determined by standard methods of analysis, such as thin layer chromatography (TLC), gel electrophoresis, high performance liquid chromatography (HPLC) and mass spectrometry (MS), used by those of skill in the art to assess such purity, or sufficiently pure such that further purification would not detectably alter the physical and chemical properties, such as enzymatic and biological activities, of the substance. Thus, substantially pure object species (e.g., compound) is the predominant species present (i.e., on a molar basis it is more abundant than any other individual species in the composition). In certain embodiments, a substantially purified fraction is a composition wherein the object species contains at least about 50 percent (on a molar basis) of all species present. In certain embodiments, a substantially pure composition will contain more than about 50%, 60%, 70%, 80%, 85%, 90%, 95%, or 99% of all species present in the composition. In certain embodiments, a substantially pure composition will contain more than about 80%, 85%, 90%, 95%, or 99% of all species present in the composition. Methods for purification of the compounds to produce substantially chemically pure compounds are known to those of skill in the art. A substantially chemically pure compound can, however, be a mixture of stereoisomers. In such instances, further purification might increase the specific activity of the compound. The instant disclosure is meant to include all such possible isomers, as well as, their racemic and optically pure forms. Optically active (+) and (−), (R)- and (S)-, or (D)- and (L)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, such as reverse phase HPLC. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.
As used herein, the term “co-administer” refers to administering more than one pharmaceutical agent to a patient. In certain embodiments, co-administered pharmaceutical agents are administered together in a single dosage unit.

Examples of characteristics that constitute phenotype included, but are not limited to, cell size, cell proliferation, cell differentiation, cell survival, apoptosis (cell death), or the utilization of a metabolic nutrient (e.g., glucose uptake). Certain changes or the absence of changes in cell phenotype are readily monitored using techniques known in the art.
As used herein, the term “cell proliferation” refers to the rate at which cells divide. The number of cells growing in a vessel can be quantified by a person skilled in the art (e.g., by counting cells in a defined area using a light microscope, or by using laboratory apparatus that measure the density of cells in an appropriate medium). One skilled in that art can calculate cell proliferation by determining the number of cells at two or more times.
As used herein, the term “contacting” refers to bringing two or more materials into close enough proximity that they can interact. In certain embodiments, contacting can be accomplished in a vessel such as a test tube, a petri dish, or the like. In certain embodiments, contacting can be performed in the presence of additional materials. In certain embodiments, contacting can be performed in the presence of cells. In certain of such embodiments, one or more of the materials that are being contacted can be inside a cell. Cells can be alive or can be dead. Cells can or cannot be intact.

C. Preparation of the Compounds
In certain embodiments, of the compounds provided herein can be synthesized using the following synthesis schemes. In each of the Schemes the R groups correspond to the definitions described above.




Scheme I describes the alkylation of the substituted anilines such as Structure 1. Reductive alkylation of the substituted anilines (e.g., Structure 1) with an aldehyde or ketone or acid in the presence of a reducing agent, such as sodium cyanoborohydride or sodium borohydride affords compounds of Structure 2. Alternatively, treatment of the substituted anilines of Structure 1 with an organohalide in the presence of a base provides the compounds of Structure 2.





Scheme II describes the preparation of compounds of Structure 5 from the substituted aryl halides such as Structure 3. Palladium catalyzed coupling reaction of Structure 3 and compounds of Structure 4 provide the products of Structure 5.





Scheme III describes the indole synthesis from substituted anilines such as Structure 6. Diazotization of the substituted anilines (e.g., Structure 6) followed by treatment with a reducing agent, such tin dichloride affords the corresponding hydrazine. Treatment of the hydrazines with a ketone, such as Structure 7, under acidic conditions affords the indoles of Structure 8.




Scheme IV describes the substitution reaction of aromatic fluorides of Structure 9 with amines such as Structure 10 to give compounds of Structure 11.




Scheme V describes the substitution reaction of aromatic fluorides of Structure 12 with amino alcohols to give compounds of Structure 13. Alkylation of the nitrogen atom, followed by cyclization gives the substituted benzoxazines of Structure 14.




Scheme V describes the synthesis of indoles of structure 16, from hydrazines such as 15. Alkylation of the nitrogen atom under reductive conditions gives the indolines of Structure 17. These can be oxidized to the N-alkylated indoles of Structure 18.




Scheme VII describes the nitration reaction of fused heterocyclic aromatics of Structure 19 with nitric acid to give compounds of Structure 20.
In certain embodiments, provided herein is a salt corresponding to any of the compounds provided herein. In certain embodiments, the salt corresponding to a selective androgen receptor modulator or selective androgen binding agent is provided herein.

Typically, the compositions are formulated for single dosage administration. To formulate a composition, the weight fraction of compound is dissolved, suspended, dispersed or otherwise mixed in a selected vehicle at an effective concentration such that the treated condition is relieved or ameliorated. Pharmaceutical carriers or vehicles suitable for administration of the compounds provided herein include any such carriers known to those skilled in the art to be suitable for the particular mode of administration.
In addition, the compounds can be formulated as the sole pharmaceutically active ingredient in the composition or can be combined with other active ingredients. Liposomal suspensions, including tissue-targeted liposomes, such as tumor-targeted liposomes, can also be suitable as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art. For example, liposome formulations can be prepared as described in U.S. Pat. No. 4,522,811. Briefly, liposomes such as multilamellar vesicles (MLV's) can be formed by drying down egg phosphatidyl choline and brain phosphatidyl serine (7:3 molar ratio) on the inside of a flask. A solution of a compound provided herein in phosphate buffered saline lacking divalent cations (PBS) is added and the flask shaken until the lipid film is dispersed. The resulting vesicles are washed to remove unencapsulated compound, pelleted by centrifugation, and then resuspended in PBS.
The active compound is included in the pharmaceutically acceptable carrier in an amount sufficient to exert a therapeutically useful effect in the absence of undesirable side effects on the patient treated.
The concentration of active compound in the pharmaceutical composition will depend on absorption, inactivation and excretion rates of the active compound, the physicochemical characteristics of the compound, the dosage schedule, and amount administered as well as other factors known to those of skill in the art. For example, the amount that is delivered is sufficient to ameliorate one or more of the symptoms of diseases or disorders associated with androgen activity or in which androgen activity is implicated, as described herein.
The effective amount of a compound provided herein can be determined by one of ordinary skill in the art, and includes exemplary dosage amounts for a mammal of from about 0.05 to 100 mg/kg of body weight of active compound per day, which can be administered in a single dose or in the form of individual divided doses, such as from 1 to 4 times per day. It will be understood that the specific dose level and frequency of dosage for any particular subject can be varied and will depend upon a variety of factors, including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the species, age, body weight, general health, sex and diet of the subject, the mode and time of administration, rate of excretion, drug combination, and severity of the particular condition.
The active ingredient can be administered at once, or can be divided into a number of smaller doses to be administered at intervals of time. It is understood that the precise dosage and duration of treatment is a function of the disease being treated and can be determined empirically using known testing protocols or by extrapolation from in vivo or in vitro test data. It is to be noted that concentrations and dosage values can also vary with the severity of the condition to be alleviated.
It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the compounds, compositions, methods and other subject matter provided herein.
Pharmaceutically acceptable derivatives include acids, bases, enol ethers and esters, salts, esters, hydrates, solvates and prodrug forms. The derivative is selected such that its pharmacokinetic properties are superior to the corresponding neutral compound.
Thus, effective concentrations or amounts of one or more of the compounds described herein or pharmaceutically acceptable derivatives thereof are mixed with a suitable pharmaceutical carrier or vehicle for systemic, topical or local administration to form pharmaceutical compositions. Compounds are included in an amount effective for ameliorating one or more symptoms of, or for treating or preventing diseases or disorders associated with androgen receptor activity or in which androgen receptor activity is implicated, as described herein. The concentration of active compound in the composition will depend on absorption, inactivation, excretion rates of the active compound, the dosage schedule, amount administered, particular formulation as well as other factors known to those of skill in the art.
The compositions are intended to be administered by a suitable route, including orally in form of capsules, tablets, granules, powders or liquid formulations including syrups; parenterally, such as subcutaneously, intravenously, intramuscularly, with inteasternal injection or infusion techniques (as sterile injectable aq. or non-aq. solutions or suspensions); nasally such as by inhalation spray; topically, such as in the form of a cream or ointment; rectally such as in the form of suppositories; liposomally; and locally. The compositions can be in liquid, semi-liquid or solid form and are formulated in a manner suitable for each route of administration.

For example, in certain embodiments, pharmaceutical compositions include liposomes coated with a tissue-specific antibody.
In certain embodiments, a pharmaceutical composition containing one or more compounds provided herein contains a co-solvent system. Certain of such co-solvent systems contain, for example, benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. In certain embodiments, such co-solvent systems are used for hydrophobic compounds. A non-limiting example of such a co-solvent system is the VPD co-solvent system, which is a solution of absolute ethanol containing 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant Polysorbate 80TM, and 65% w/v polyethylene glycol 300. The proportions of such co-solvent systems may be varied considerably without significantly altering their solubility and toxicity characteristics. Furthermore, the identity of co solvent components may be varied: for example, other surfactants may be used instead of Polysorbate 80TM; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g., polyvinyl pyrrolidone; and other sugars or polysaccharides may substitute for dextrose.
In certain embodiments, solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include any of the following components: a sterile diluent, such as water for injection, saline solution, fixed oil, polyethylene glycol, glycerine, propylene glycol or other synthetic solvent; antimicrobial agents, such as benzyl alcohol and methyl parabens; antioxidants, such as ascorbic acid and sodium bisulfite; chelating agents, such as ethylenediaminetetraacetic acid (EDTA); buffers, such as acetates, citrates and phosphates; and agents for the adjustment of tonicity such as sodium chloride or dextrose. Parenteral preparations can be enclosed in ampules, disposable syringes or single or multiple dose vials made of glass, plastic or other suitable material.
In instances in which the compounds exhibit insufficient solubility, methods for solubilizing compounds can be used. Such methods are known to those of skill in this art, and include, but are not limited to, using cosolvents, such as dimethylsulfoxide (DMSO), using surfactants, such as TWEEN®, or dissolution in aqueous sodium bicarbonate. Derivatives of the compounds, such as prodrugs of the compounds can also be used in formulating effective pharmaceutical compositions.
In certain embodiments, a pharmaceutical composition containing one or more compounds provided herein contains a sustained-release system. A non-limiting example of such a sustained-release system is a semipermeable matrix of solid hydrophobic polymers. In certain embodiments, sustained release systems may, depending on their chemical nature, release compounds over a period of hours, days, weeks or months.
In certain embodiments, upon mixing or addition of the compound(s), the resulting mixture can be a solution, suspension, emulsion or the like. The form of the resulting mixture depends upon a number of factors, including the intended mode of administration and the solubility of the compound in the selected carrier or vehicle. The effective concentration is sufficient for ameliorating the symptoms of the disease, disorder or condition treated and can be empirically determined.
The pharmaceutical compositions are provided for administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, granules, sterile parenteral solutions or suspensions, and oral solutions or suspensions, and oil-water emulsions containing suitable quantities of the compounds or pharmaceutically acceptable derivatives thereof. The pharmaceutically active compounds and derivatives thereof are typically formulated and administered in unit-dosage forms or multiple-dosage forms. Unit-dose forms as used herein refers to physically discrete units suitable for human and animal subjects and packaged individually as is known in the art. Each unit-dose contains a predetermined quantity of the therapeutically active compound sufficient to produce the desired therapeutic effect, in association with the required pharmaceutical carrier, vehicle or diluent. Examples of unit-dose forms include ampoules and syringes and individually packaged tablets or capsules. Unit-dose forms can be administered in fractions or multiples thereof. A multiple-dose form is a plurality of identical unit-dosage forms packaged in a single container to be administered in segregated unit-dose form. Examples of multiple-dose forms include vials, bottles of tablets or capsules or bottles of pints or gallons. Hence, multiple dose form is a multiple of unit-doses which are not segregated in packaging.
The composition can contain along with the active ingredient: a diluent such as lactose, sucrose, dicalcium phosphate, or carboxymethylcellulose; a lubricant, such as magnesium stearate, calcium stearate and talc; and a binder such as starch, natural gums, such as gum acaciagelatin, glucose, molasses, polyinylpyrrolidine, celluloses and derivatives thereof, povidone, crospovidones and other such binders known to those of skill in the art. Liquid pharmaceutically administrable compositions can, for example, be prepared by dissolving, dispersing, or otherwise mixing an active compound as defined above and optional pharmaceutical adjuvants in a carrier, such as, for example, water, saline, aqueous dextrose, glycerol, glycols, ethanol, and the like, to thereby form a solution or suspension. If desired, the pharmaceutical composition to be administered can also contain minor amounts of nontoxic auxiliary substances such as wetting agents, emulsifying agents, or solubilizing agents, pH buffering agents and the like, for example, acetate, sodium citrate, cyclodextrin derivatives, sorbitan monolaurate, triethanolamine sodium acetate, triethanolamine oleate, and other such agents. Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pa., 15th Edition, 1975. The composition or formulation to be administered will, in any event, contain a quantity of the active compound in an amount sufficient to alleviate the symptoms of the treated subject.
Dosage forms or compositions containing active ingredient in the range of 0.005% to 100% with the balance made up from non-toxic carrier can be prepared. For oral administration, a pharmaceutically acceptable non-toxic composition is formed by the incorporation of any of the normally employed excipients, such as, for example pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose derivatives, sodium crosscarmellose, glucose, sucrose, magnesium carbonate or sodium saccharin. Such compositions include solutions, suspensions, tablets, capsules, powders and sustained release formulations, such as, but not limited to, implants and microencapsulated delivery systems, and biodegradable, biocompatible polymers, such as collagen, ethylene vinyl acetate, polyanhydrides, polyglycolic acid, polyorthoesters, polylactic acid and others. Methods for preparation of these compositions are known to those skilled in the art. The contemplated compositions can contain 0.001%-100% active ingredient, in one embodiment 0.1-85%, in another embodiment 75-95%.
In certain embodiments, the compounds can be administered in a form suitable for immediate release or extended release. Immediate release or extended release can be achieved with suitable pharmaceutical compositions or, particularly in the case of extended release, with devices such as subcutaneous implants or osmotic pumps.

It is to be understood that such combination therapy constitutes a further aspect of the compositions and methods of treatment provided herein.
In certain embodiments, a pharmaceutical composition containing one or more compounds provided herein is formulated as a prodrug. In certain embodiments, prodrugs are useful because they are easier to administer than the corresponding active form. For example, in certain instances, a prodrug may be more bioavailable (e.g., through oral administration) than is the corresponding active form. In certain instances, a prodrug may have improved solubility compared to the corresponding active form. In certain embodiments, a prodrug is an ester. In certain embodiments, such prodrugs are less water soluble than the corresponding active form. In certain instances, such prodrugs possess superior transmittal across cell membranes, where water solubility is detrimental to mobility. In certain embodiments, the ester in such prodrugs is metabolically hydrolyzed to carboxylic acid. In certain instances the carboxylic acid containing compound is the corresponding active form. In certain embodiments, a prodrug contains a short peptide (polyaminoacid) bound to an acid group. In certain of such embodiments, the peptide is metabolized to form the corresponding active form.
In certain embodiments, a pharmaceutical composition containing one or more compounds provided herein is useful for treating a conditions or disorder in a mammalian, and particularly in a human patient. Suitable administration routes include, but are not limited to, oral, rectal, transmucosal, intestinal, enteral, topical, suppository, through inhalation, intrathecal, intraventricular, intraperitoneal, intranasal, intraocular and parenteral (e.g., intravenous, intramuscular, intramedullary, and subcutaneous). In certain embodiments, pharmaceutical compositions are administered to achieve local rather than systemic exposures. For example, pharmaceutical compositions may be injected directly in the area of desired effect (e.g., in the renal or cardiac area). In certain embodiments in which the pharmaceutical composition is administered locally, the dosage regimen is adjusted to achieve a desired local concentration of a compound provided herein.
In certain embodiments, a pharmaceutical composition containing one or more compounds provided herein is administered in the form of a dosage unit (e.g., tablet, capsule, bolus, etc.). In certain embodiments, such dosage units contain a selective androgen receptor modulator in a dose from about 1 μg/kg of body weight to about 50 mg/kg of body weight. In certain embodiments, such dosage units contain a selective androgen receptor modulator in a dose from about 2 μg/kg of body weight to about 25 mg/kg of body weight. In certain embodiments, such dosage units contain a selective androgen receptor modulator in a dose from about 10 μg/kg of body weight to about 5 mg/kg of body weight. In certain embodiments, pharmaceutical compositions are administered as needed, once per day, twice per day, three times per day, or four or more times per day. It is recognized by those skilled in the art that the particular dose, frequency, and duration of administration depends on a number of factors, including, without limitation, the biological activity desired, the condition of the patient, and tolerance for the pharmaceutical composition.
In certain embodiments, a pharmaceutical composition provided herein is administered for a period of continuous therapy. For example, a pharmaceutical composition provided herein may be administered over a period of days, weeks, months, or years.
Dosage amount, interval between doses, and duration of treatment may be adjusted to achieve a desired effect. In certain embodiments, dosage amount and interval between doses are adjusted to maintain a desired concentration of compound in a patient. For example, in certain embodiments, dosage amount and interval between doses are adjusted to provide plasma concentration of a compound provided herein at an amount sufficient to achieve a desired effect. In certain of such embodiments the plasma concentration is maintained above the minimal effective concentration (MEC). In certain embodiments, pharmaceutical compositions provided herein are administered with a dosage regimen designed to maintain a concentration above the MEC for 10-90% of the time, between 30-90% of the time, or between 50-90% of the time.

The articles of manufacture provided herein contain packaging materials. Packaging materials for use in packaging pharmaceutical products are well known to those of skill in the art. See, e.g., U.S. Pat. Nos. 5,323,907, 5,052,558 and 5,033,252. Examples of pharmaceutical packaging materials include, but are not limited to, blister packs, bottles, tubes, inhalers, pumps, bags, vials, containers, syringes, bottles, and any packaging material suitable for a selected formulation and intended mode of administration and treatment. A wide array of formulations of the compounds and compositions provided herein are contemplated as are a variety of treatments for any disease or disorder in which androgen receptor activity is implicated as a mediator or contributor to the symptoms or cause.
In certain embodiments, the pharmaceutical compositions can be presented in a pack or dispenser device which can contain one or more unit dosage forms containing a compound provided herein. The pack can for example contain metal or plastic foil, such as a blister pack. The pack or dispenser device can be accompanied by instructions for administration. The pack or dispenser can also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, can be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. Compositions containing a compound provided herein formulated in a compatible pharmaceutical carrier can also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition.
E. Evaluation of the Activity of the Compounds
Standard physiological, pharmacological and biochemical procedures are available for testing the compounds provided herein to identify those that possess activity as androgen receptor modulators. In vitro and in vivo assays known in the art can be used to evaluate the activity of the compounds provided herein as androgen receptor modulators. Exemplary assays include, but are not limited to fluorescence polarization assay, luciferase assay, co-transfaction assay. In certain embodiments, the compounds provided herein are capable of modulating activity of androgen receptor in a “co-transfection” assay (also called a “cis-trans” assay), which is known in the art. See e.g., Evans et al., Science, 240:889-95 (1988); U.S. Pat. Nos. 4,981,784 and 5,071,773; Pathirana et al., “Nonsteroidal Human Progesterone Receptor Modulators from the Marie Alga Cymopolia Barbata,” Mol. Pharm. 47:630-35 (1995)). Modulating activity in a co-transfection assay has been shown to correlate with in vivo modulating activity. Thus, in certain embodiments, such assays are predictive of in vivo activity. See, e.g., Berger et al., J. Steroid Biochem. Molec. Biol. 41:773 (1992).
In certain co-transfection assays, two different co-transfection plasmids are prepared. In the first co-transfection plasmid, cloned cDNA encoding an intracellular receptor (e.g., androgen receptor) is operatively linked to a constitutive promoter (e.g., the SV 40 promoter). In the second co-transfection plasmid, cDNA encoding a reporter protein, such as firefly luciferase (LUC), is operatively linked to a promoter that is activated by a receptor-dependent activation factor. Both co-transfection plasmids are co-transfected into the same cells. Expression of the first co-transfection plasmid results in production of the intracellular receptor protein. Activation of that intracellular receptor protein (e.g., by binding of an agonist) results in production of a receptor-dependent activation factor for the promoter of the second co-transfection plasmid. That receptor-dependent activation factor in turn results in expression of the reporter protein encoded on the second co-transfection plasmid. Thus, reporter protein expression is linked to activation of the receptor. Typically, that reporter activity can be conveniently measured (e.g., as increased luciferase production).
Certain co-transfection assays can be used to identify agonists, partial agonists, and/or antagonists of intracellular receptors. In certain embodiments, to identify agonists, co-transfected cells are exposed to a test compound. If the test compound is an agonist or partial agonist, reporter activity is expected to increase compared to co-transfected cells in the absence of the test compound. In certain embodiments, to identify antagonists, the cells are exposed to a known agonist (e.g., androgen for the androgen receptor) in the presence and absence of a test compound. If the test compound is an antagonist, reporter activity is expected to decrease relative to that of cells exposed only to the known agonist.
In certain embodiments, compounds provided herein are used to detect the presence, quantity and/or state of receptors in a sample. In certain of such embodiments, samples are obtained from a patient. In certain embodiments, compounds are radio- or isotopically-labeled. For example, compounds provided herein that selectively bind androgen receptors may be used to determine the presence of such receptors in a sample, such as cell homogenates and lysates.
