The 3-(4-cyano-3-trifluoromethylphenyl)-5,5-dimethylthiohydantoin derivatives which have carboxy-terminal side chains were synthesized and their agonistic/antagonistic activities against androgen receptor (AR) measured. Among them, compound 13b showed antagonistic activity (IC50=130 nM) with no agonistic activity even at 10000 nM. This compound exhibited significant metabolic stability and oral antiandrogenic activity (ED50=7 mg/kg).
合成了具有羧基末端侧链的3-(4-氰基-3-三氟甲基苯基)-5,5-二甲硫基乙内酰脲衍生物,并测量了它们对雄激素受体(AR)的激动/拮抗活性。其中,化合物13b显示拮抗活性(IC50=130 nM),即使在10000 nM也无激动活性。该化合物表现出显着的代谢稳定性和口服抗雄激素活性(ED50 = 7 mg/kg)。
