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 1 is a potent AR antagonist in the rat prostate (ID50= 0.15 mg/day).
