piperidine-2,6-dione] as inhibitors of the cholesterol side-chain cleavage enzyme system desmolase and the estrogen forming system aromatase, analogues have been synthesized in which the aminophenyl substituent is replaced by pyridyl or substituted pyridyl. The 4-pyridyl analogue 5 [3-ethyl-3-(4-pyridyl)-piperidine-2,6-dione] is a strong competitive inhibitor of aromatase (Ki = 1.1 microM; value for
在进一步探讨影响氨基谷氨酰胺[1,3-(4-氨基苯基)-3-乙基哌啶-2,6-二酮]类似物的相对功效的结构特征时,这些抑制剂作为胆固醇侧链裂解酶系统脱糖酶和合成了雌激素形成系统芳香酶,其中氨基苯基取代基被吡啶基或取代的吡啶基取代的类似物。4-吡啶基类似物5 [3-乙基-3-(4-吡啶基)-哌啶-2,6-二酮]是芳香酶的强竞争性抑制剂(Ki = 1.1 microM;值1,0.60 microM),具有II型差异光谱(Ks = 0.28 microM; 1的值,0.13 microM),但对脱粘酶没有抑制作用。2-和3-吡啶基类似物(3和4)均不抑制任何酶系统。1-氨基-3-乙基-3-苯基哌啶-2,6-dione(2)是强力的脱氢酶选择性抑制剂,但4-吡啶基类似物10 [1-氨基-3-乙基-3-(4-吡啶基)-哌啶-2,6-dione]是弱抑制剂脱模酶和芳香化酶。还制备了具有较少碱性芳族取代基的5的类似物,即N-氧化物11和2
