  Synthesis of potent and tissue-selective androgen receptor modulators (SARMs): 2-(2,2,2)-Trifluoroethyl-benzimidazole scaffold

  摘要：

  The synthesis and in vivo SAR of 2-(2,2,2)-trifluoroethyl-benzimidazoles are described. Prostate antagonism and/or levator am agonism can be modulated by varying the substitution at the 2-position of 5,6-dichloro-benzimidazoles. Potent androgen agonists on the muscle were discovered that strongly bind to the androgen receptor (2-17 nM) and show potent in vivo efficacy (0.03-0.11 mg/day). True SARMs showing both prostate antagonism and levator am agonism were revealed. (c) 2006 Elsevier Ltd. All rights reserved.

  Synthesis and SAR of potent and selective androgen receptor antagonists: 5,6-Dichloro-benzimidazole derivatives

  摘要：

  The synthesis and in vivo SAR of 5,6-dichloro-benzimidazole derivatives as novel selective androgen receptor antagonists are described. During screening of 2-alkyl benzimidazoles, it was found that a trifluoromethyl group greatly enhances antagonist activity in the prostate. Benzimidazole I is a potent AR antagonist in the rat prostate (ID50 = 0.15 mg/day). (c) 2006 Elsevier Ltd. All rights reserved.

  The synthesis and in vivo SAR of N-benzyl, N-aceto, and N-ethylene ether derivatives of 2-(2,2,2-trifluoroethyl)-5,6dichloro-benzimidazole as novel androgen receptor antagonists are described. SAR studies led to the discovery of 4-bromo-benzyl benzimidazole 17 as a more potent androgen receptor antagonist in the rat prostate (ID50 = 0.13 mg/day), compared with bicalutamide (ID50 = 0.23 mg/day).
