3-(4'-Aminophenyl)pyrrolidine-2,5-dione (WSP3), a known reversible inhibitor of P450 aromatase, was modified using molecular graphics and our model of reversible inhibitor and substrate binding to resemble 10 beta-prop-2-ynylestr-4-ene-3,17-dione (PED), a mechanism-based inactivator of the enzyme. The analogues prepared were 3-substituted 3-(prop-2-enyl) or 3-(prop-2-ynyl) pyrrolidine-2,5-diones and
3-(4'-氨基苯基)吡咯烷-2,5-二酮(WSP3),一种已知的P450芳香化酶可逆抑制剂,已使用分子图形进行了修饰,我们的可逆抑制剂和底物结合模型类似于10 beta-prop-2- ynylestr-4-ene-3,17-dione(PED),一种基于机理的酶灭活剂。制备的类似物是3-取代的3-(丙-2-烯基)或3-(丙-2-炔基)吡咯烷-2,5-二酮及其N-烷基衍生物。报告的化合物对人胎盘P450芳香酶没有抑制作用(时间依赖性)。然而,在几种3-(丙-2-炔基)化合物中观察到一些可逆的活性。
