3-Ethyl-3-(4-pyridyl)piperidine-2,6-dione (1) is a strong competitive inhibitor of human placental aromatase (Ki = 1.1 microM; testosterone as substrate) that, unlike the structurally related aromatase inhibitor aminoglutethimide (2), is not also an inhibitor of the cholesterol side-chain cleavage enzyme desmolase. An improved synthesis of 1 is described, which was readily adapted to the preparation
3-乙基-3-(4-吡啶基)哌啶-2,6-二酮(1)是人类胎盘芳香酶(Ki = 1.1 microM;睾丸激素为底物)的强竞争抑制剂,与结构相关的芳香酶抑制剂氨基谷氨酰胺( 2),它也不是胆固醇侧链裂解酶脱糖酶的抑制剂。描述了1的改进的合成,其易于适应于一系列3-烷基-3-(4-吡啶基)-哌啶-2,6-二酮(6-13)中的同系物的制备。1的烷基化得到第二系列,其包含1-烷基-3-乙基-3-(4-吡啶基)-哌啶-2,6-二酮(14-23)。对于辛基衍生物,在两个系列中对芳香化酶的抑制活性最大。以睾丸酮为底物的3-辛基(12)和1-辛基(21)类似物发挥竞争抑制作用的Ki值分别为0.09和0.12 microM。化合物1、2、12和21作为睾丸激素和雄烯二酮芳构化抑制剂的相对效能不同。各自的Ki值如下:1、1.1和14 microM(比率12.7);2,0.6和1.8 microM(3); 12、0
