provides an enhanced fit into this active site S2 pocket. In the present paper, we also report on the structure of these inhibitors in solution and conformational analysis of inhibitors in the active site in order to asses the consequences of the replacement of the central alpha-CH by a nitrogen functionality. In vitro biological testing of the designed inhibitors shows that elimination of R, S stereoisomerism
理论和结构研究,然后进行定向合成和体外生物学测试,使我们获得了新型的非共价凝血酶假肽抑制剂。我们已经将氮杂肽支架整合到经典三肽D-Phe-Pro-Arg抑制剂结构的中心部分,从而从分子中消除了一个立体定位中心。设计了一系列化合物以优化凝血酶S2口袋的占用率。在P2处增加的疏水性增强了对该活性位点S2口袋的贴合性。在本文中,我们还报告了这些抑制剂在溶液中的结构以及活性位点中抑制剂的构象分析,以评估氮官能团取代中心α-CH的后果。
