atoms at both C-2 and C-4 positions (13β-, 13α-methyl-17-keto halogen derivatives) were the most potent inhibitors of AKR1C1. The lowest IC50 values were for the 13α-epimers 2_2I,4Br and 2_2I,4Cl (IC50, 0.7 μM, 0.8 μM, respectively), both of which selectively inhibited the AKR1C1 isoform. The 13α-methyl-17-keto halogen derivatives 2_2Br and 2_4Cl were the most potent inhibitors of AKR1C2 (IC50, 1.5 μM
摘要 酶 AKR1C 在受体前水平调节雌激素、雄激素和孕酮的作用,并且还与化学抗性有关。在重组 AKR1C 酶上研究了这些雌酮卤化物的活性。在 C-2 和 C-4 位具有卤原子的雌酮卤化物(13β-、13α-甲基-17-酮卤衍生物)是 AKR1C1 最有效的抑制剂。最低的 IC 50值是针对13α-差向异构体2 _2I,4Br 和2 _2I,4Cl(IC 50分别为 0.7 μM、0.8 μM),它们都选择性地抑制了 AKR1C1 异构体。13α-甲基-17-酮卤衍生物2 _2Br 和2 _4Cl 是最有效的 AKR1C2 抑制剂 (IC 50,分别为 1.5 μM 和 1.8 μM),对 AKR1C2 同种型具有高选择性。化合物1 _2Cl,4CL显示出最好的AKR1C3抑制,而且它也能抑制AKR1C1(KI:AKR1C1,0.69μM; AKR1C3,1.43μM)。这些数据表明,雌酮
