Inhibitors of the cytochrome P450 enzyme aromatase, which is involved in the biosynthesis of estrogens from androgens, are of proven utility in the treatment of hormone-dependent breast cancer. The determination of the crystal structure of one such inhibitor, 3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (2) and its 3-butyl analogue (3) is described. In the absence of three-dimensional structural information
细胞色素P450酶芳香酶的抑制剂与雄激素的生物合成有关,已证明可用于治疗激素依赖性乳腺癌。描述了一种这样的抑制剂3-乙基-3-(4-吡啶基)哌啶-2,6-二酮(2)及其3-丁基类似物(3)的晶体结构的确定。在缺乏该酶的三维结构信息的情况下,为了确定可能的“活性”构象,进行了构象分析和与天然底物的比较。3的增强抑制活性可能与侧链和通常与类固醇底物的B和C环相互作用的酶部分之间的疏水相互作用有关。
