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。
Improved tack, green strength or non-black filler interaction capability are realized in a treated diene rubber. The method of treating diene rubberto achieve the improvements is shown, together with a composition in which maleamic acid or derivatives of maleamic acid are combined with sulfur or an organic sulfur compound capable of generating a thiyl radical.
