features responsible for the inhibitory activity of aminoglutethimide [3-(4-aminophenyl)-3-ethylpiperidine-2,6-dione] (1) toward the cholesterol side chain cleavage (CSCC) enzyme from bovine adrenals and the human placental aromatase enzyme, analogues have been synthesized in which the piperidine-2,6-dione ring is replaced by substituted or unsubstituted azabicyclo[3.1.0]hexane-2,4-dione rings. The unsubstituted
在探索氨基谷氨酰胺[3-(4-氨基苯基)-3-乙基哌啶-2,6-二酮](1)对牛肾上腺和人的胆固醇侧链裂解(CSCC)酶的抑制活性的结构特征时合成了胎盘芳香酶,其中哌啶-2,6-二酮环被取代或未取代的氮杂双环[3.1.0]己烷-2,4-二酮环取代。未取代的类似物1-(4-氨基苯基)-3-氮杂双环[3.1.0]己烷-2,4-二酮(9a)是一种比1更为有效的芳香化酶抑制剂(Ki = 1.2 microM,参见1.8 microM 1)但对CSCC酶无抑制作用。取代的类似物1-(4-氨基苯基)-3-丁基-3-氮杂双环[3.1.0]己烷-2,4-二酮(9e)和1-(4-氨基苯基)-3-戊基-3-氮杂双环[ 3.1.0]己烷-2,4-二酮(9f)在抑制芳香化酶方面的效力比1(Ki值分别为1、9e和9f分别为1.8、0.015和0.02 microM)高1倍,对CSCC酶没有明显的活性。II型差异谱在
