  Xa因子活性位点的分子识别：阳离子-π相互作用，平面肽表面堆积和结构水的置换

  摘要：

  Xa因子是一种来自凝血级联的丝氨酸蛋白酶，是分子识别研究的理想酶，因为其活性位点具有高度的形状持久性，并具有独特的凹子口袋。我们开发了一系列非肽小分子抑制剂，这些抑制剂具有中心三环核，该核将中性杂环取代基定向到S1袋中，并将季铵离子定向到S4袋中的芳族盒中。系统地改变了取代基的种类，以研究S4口袋中的阳离子与π相互作用，S1口袋内衬的扁平肽壁上的最佳杂环堆积以及S1和S4口袋中的潜在水替代物。建立了构效关系，以揭示和量化对结合自由焓的贡献，由单原子替换或配体位置变化引起的。一系列高亲和力配体，抑制常数低至获得了K i = 2 n M，并通过蛋白质-配体复合物的X射线共晶体结构证实了其拟定的结合几何形状。
