Protocol

Kinase Assay [1]
The human cancer epithelial breast cell lines MDA MB-453 and T47D, which endogenously express AR and progesterone receptor (PR), respectively, are used for radioligand competition binding assays. Binding assays are conducted by incubating BMS-564929 at various concentrations with either [3H]DHT or [3H]progesterone with the cells for 2 h at room temperature. For ERα and ERβ, fusion proteins expressed in Escherichia coli, consisting of maltose binding protein, a specific biotinylation sequence, an enterokinase cleavage site, and either the ERα or ERβ LBD is used. Binding reactions are conducted by incubating ERα and ERβ LBD with BMS-564929 and [3H]E2 for 2 h at room temperature. Specific binding activity to the mineralocorticoid receptor (MR) by BMS-564929 is evaluated by competition binding assay using kidney cytosolic preparations and [3H]aldosterone. The kidneys are obtained from adrenalectomized rats to remove the endogenous source of aldosterone and to increase the MR concentration in the cytosol of kidney cells. Binding reactions are incubated for 2 h on ice in the presence of excess mifepristone (RU486) to block nonspecific glucocorticoid receptor (GR) binding. A fluorescence polarization based assay is used for GR binding, as per manufacturer recommendations. Inhibitory constants (Ki, app) defining apparent binding affinity of test compounds to intracellular receptors are calculated from the observed inhibition of natural ligand binding at multiple concentrations of test compound. SHBG binding is performed using a standard charcoal assay. Reagents: 1 mg lyophilized SHGB powder (Tris), [3H]DHT, 3% charcoal, and 0.4% Dextran in PBS; binding buffer: 50 mM Tris, pH 7.6, 100 mM NaCl, 1 mM EDTA, 1 mM DTT, and mock lysate (3.5 μg/100 μL buffer); stock solutions: stock SHBG protein: 1 mg/mL in water=20 μM; stock [3H]DHT ligand: 9 μM; DHT: 10 mM in DMSO; BMS 564929: 10 mM in DMSO. Compounds diluted in binding buffer are added to 40 nM [3H]DHT and 20 nM SHBG protein in 200 μL volume and incubated for 1 h at room temperature. Total binding: 40 nM [3H]DHT and 20 nM SHBG protein in 200 μL volume; nonspecific binding: 40 nM [3H]DHT and 20 nM SHBG protein and 1 mM cold DHT in 200 μL volume. At the end of the incubation period, 200 μL of the charcoal solution (3% containing 0.04% dextran) is added to 200 μL of the reactions and shaken for 15 min before centrifugation. Supernatant (200 μL) is then transferred to the wells of a 24-well white Optiplate; 200 μL of scintillant are added with mixing. Radioactivity counts are read in Topcount[1].

Animal Administration [1]
Rats[1] Matched sets of castrated, sexually mature Harlan Sprague Dawley rats (42-56 d old, 200-250 g) are dosed once daily by oral gavage with BMS-564929 (0.00001-10 mg/kg) in solution/suspension of 80% PEG 400 and 20% Tween 20 for 14 d. Two control groups, one sham operated intact and one castrated, are dosed orally with the PEG/TW vehicle only, beginning on d 15 after surgery. Animals are dosed (vol/wt) at 1 mL/kg body weight. T propionate (TP) is dosed once daily sc in a 10% ethanol/90% peanut oil vehicle as a reference compound (0.03-10 mg/kg). After 14 d of treatment, the animals are killed by carbon dioxide asphyxiation, the levator ani and the ventral prostate are surgically removed and weighed, and serum is collected for LH measurements.

Background on BMS-564929

BMS-564929 is a selective androgen receptor (AR) modulator with Ki value of 2.11 ± 0.16 nM [1].
The AR is a type of nuclear receptor that is activated by the androgenic hormones, testosterone, or dihydrotestosterone. The important function is regulating gene expression.
BMS-564929 is a muscle-tissue specific agonist for AR with a bicyclic hydantoin structure [2]. BMS-564929 is about 400-fold selective for AR vs. PR and more than 1000-fold selective for AR vs. GR, MR and ERα and β. In the C2C12 myoblast cell line, BMS-564929 shows a potency of 0.44 ± 0.03 nM compared with 2.81 ± 0.48 nM measured for testosterone [1].
In castrated male rats, BMS-564929 is substantially more potent than testosterone (T) in promoting the growth of the levator ani muscle, and is highly selective for muscle vs. Prostate. Because of its potent oral activity and tissue selectivity, BMS-564929 is expected to yield beneficial clinical effects in muscle and other tissues with a more favorable safety way [1].

Determination of benzimidazole- and bicyclic hydantoin-derived selective androgen receptor antagonists and agonists in human urine using LC-MS/MS.[Pubmed:18270691]

Selective androgen receptor modulators (SARMs) represent a novel class of drugs with tissue-specific agonistic and antagonistic properties, which are prohibited in sports from January 2008 according to the World Anti-Doping Agency. Preventive approaches to restrict the use of SARMs include early implementation of target analytes into doping control screening assays. Five model SARMs were synthesized, four of which are analogs to prostate-specific androgen receptor antagonists with a 5,6-dichloro-benzimidazole nucleus. The fifth SARM is a muscle-tissue specific agonist with a bicyclic hydantoin structure (BMS-564929). Dissociation pathways after negative electrospray ionization were studied using an LTQ-Orbitrap mass analyzer, and diagnostic product ions and common fragmentation patterns were employed to establish a screening procedure that target the intact SARMs as well as putative metabolic products. Sample preparation based on solid-phase extraction and subsequent LC-MS/MS measurement allowed for detection limits of 1-20 ng/mL, intra- and interday precisions of between 2.4 and 13.2% and between 6.5 and 24.2%, respectively. Recoveries varied from 89 to 106%, and tests for ion suppression or enhancement effects were negative for all analytes. [figure: see text]

Pharmacological and x-ray structural characterization of a novel selective androgen receptor modulator: potent hyperanabolic stimulation of skeletal muscle with hypostimulation of prostate in rats.[Pubmed:17008401]

Endocrinology. 2007 Jan;148(1):4-12.

A novel, highly potent, orally active, nonsteroidal tissue selective androgen receptor (AR) modulator (BMS-564929) has been identified, and this compound has been advanced to clinical trials for the treatment of age-related functional decline. BMS-564929 is a subnanomolar AR agonist in vitro, is highly selective for the AR vs. other steroid hormone receptors, and exhibits no significant interactions with SHBG or aromatase. Dose response studies in castrated male rats show that BMS-564929 is substantially more potent than testosterone (T) in stimulating the growth of the levator ani muscle, and unlike T, highly selective for muscle vs. prostate. Key differences in the binding interactions of BMS-564929 with the AR relative to the native hormones were revealed through x-ray crystallography, including several unique contacts located in specific helices of the ligand binding domain important for coregulatory protein recruitment. Results from additional pharmacological studies effectively exclude alternative mechanistic contributions to the observed tissue selectivity of this unique, orally active androgen. Because concerns regarding the potential hyperstimulatory effects on prostate and an inconvenient route of administration are major drawbacks that limit the clinical use of T, the potent oral activity and tissue selectivity exhibited by BMS-564929 are expected to yield a clinical profile that provides the demonstrated beneficial effects of T in muscle and other tissues with a more favorable safety window.

Detection of SARMs in doping control analysis.[Pubmed:28137616]

Mol Cell Endocrinol. 2018 Mar 15;464:34-45.

The class of selective androgen receptor modulators (SARMs) has been the subject of intense and dedicated clinical research over the past two decades. Potential therapeutic applications of SARMs are manifold and focus particularly on the treatment of conditions manifesting in muscle loss such as general sarcopenia, cancer-associated cachexia, muscular dystrophy, etc. Consequently, based on the substantial muscle- and bone-anabolic properties of SARMs, these agents constitute substances with significant potential for misuse in sport and have therefore been added to the Word Anti-Doping Agency's (WADA's) Prohibited List in 2008. Since then, numerous adverse analytical findings have been reported for various different SARMs, which has underlined the importance of proactive and preventive anti-doping measures concerning emerging drugs such as these anabolic agents, which have evidently been misused in sport despite the fact that none of these SARMs has yet received full clinical approval. In this review, analytical data on SARMs generated in the context of research conducted for sports drug testing purposes are summarized and state-of-the-art test methods aiming at intact drugs as well as diagnostic urinary metabolites are discussed. Doping control analytical approaches predominantly rely on chromatography hyphenated to mass spectrometry, which have allowed for appropriately covering the considerable variety of pharmacophores present in SARMs such as the non-steroidal representatives ACP-105, BMS-564929, GLPG0492 (DT-200), LG-121071, LGD-2226, LGD-4033/VK 5211, ostarine/enobosarm, RAD-140, S-40503, etc. as well as steroidal compounds such as MK-0773 and YK-11.
