A novel series of N-arylpiperazine-1-carboxamide derivatives was synthesized and their androgen receptor (AR) antagonist activities and in vivo antiandrogenic properties were evaluated. Reporter assays indicated that trans-2,5-dimethylpiperazine derivatives are potent AR antagonists, and in this series trans-N-4-[4-cyano-3-(trifluoromethyl)phenyl]-N-(2,4-difluorophenyl)-2,5-dimethylpiperazine-1-carboxamide (18g, YM-175735) exhibited the most potent antiandrogenic activity. Compared to bicalutamide, YM-175735 is an approximately 4-fold stronger AR antagonist and has slightly increased antiandrogenic activity, suggesting that YM-175735 may be useful in the treatment of prostate cancer.
合成了一系列新型N-芳基哌嗪-1-羧酰胺衍生物,并评估了它们的雄激素受体(AR)拮抗活性和体内抗雄激素特性。报告实验表明,反式-2,5-二甲基哌嗪衍生物是有效的AR拮抗剂,在这一系列化合物中,反-N-4-[4-氰基-3-(三氟甲基)苯基]-N-(2,4-二氟苯基)-2,5-二甲基哌嗪-1-羧酰胺(18g,YM-175735)表现出最强的抗雄激素活性。与比卡鲁胺相比,YM-175735的AR拮抗活性约强4倍,且抗雄激素活性略微增强,这表明YM-175735可能在前列腺癌治疗中具有潜在的应用价值。
