A series of pyrrolidine amino nitrile DPP1 inhibitors have been developed and characterized. The S2 pocket structure–activity relationship for these compounds shows significant gains in potency for DPP1 from interacting further with target residues and a network of water molecules in the binding pocket. Herein we describe the X-ray crystal structures of several of these compounds alongside an analysis
已经开发和表征了一系列吡咯烷氨基腈DPP1抑制剂。这些化合物的S2口袋结构与活性之间的关系显示,与目标残基和结合口袋中的水分子网络进一步相互作用,DPP1的效力显着提高。本文中,我们描述了其中几种化合物的X射线晶体结构,并分析了对DPP1抑制效能的影响因素,其中使用大正则蒙特卡洛模拟和自由能计算证明了对水网的稳定作用主要是由于因素。
