Zinc-binding groups (ZBGs) are exhaustively applied in the development of the new inhibitors against a wide variety of physiologically and pathologically important zinc proteases. Here the α-nitro ketone was presented as a new ZBG, which is a transition-state analog featured by the unique bifurcated hydrogen bonds at the active site of carboxypeptidase A based on the structural analysis. Introduction
锌结合基团(ZBGs)在开发针对各种生理和病理学上重要的锌蛋白酶的新抑制剂时已详尽应用。在这里,α-硝基酮是一种新的ZBG,它是一种过渡态类似物,基于结构分析,其特征是在羧肽酶A的活性位点具有独特的分叉氢键。在酮的α-位引入硝基可以提供更多的非共价相互作用,而不会损失形成四面体过渡态类似物的能力。
