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.
