摘　　要：目的基于人精子顶体酶活性位点的三维结构设计并合成新型苯并咪唑类衍生物。方法计算机模拟设计及化学合成。结果设计并合成了10个苯并咪唑类化合物,进行了抑酶活性测试。结论所有合成的化合物具有较好的抑酶活性,其中化合物8a是对照物Nα-对甲苯磺酰-L-赖氨酸氯甲基酮(TLCK)的1426倍。Objective To design and synthesize novel 1-（1H-benzimidazole-2-yl） urea compounds on the basis of the active site of human acrosin. Methods The compounds were designed by computer modeling and synthesized. Results Ten 1-（ 1H-benzimi- dazole-2-yl） urea compounds were designed and synthesized, in vitro anti-acrosin activity were tested. Conclusions The results of in vitro anti-acrosin test showed that all the compounds had better acrosin inhibitory activity than that of the control compound TLCK. A- mong them compound 8a was the most potent one, with IC50 0. 098 9 mmol/L.
