structurally novel dipeptidyl peptidase IV (DPP-4) inhibitor. In this study, we obtained the X-ray co-crystal structure between nicotinic acid derivative 1 and DPP-4. From these X-ray co-crystallography results, to achieve more potent inhibitory activity, we targeted Arg125 as a potential amino acid residue because it was located near the pyridine core, and some known DPP-4 inhibitors were reported to
我们以前已经发现烟酸衍生物1作为结构上新颖的二肽基肽酶IV(DPP-4)抑制剂。在这项研究中,我们获得了烟酸衍生物1之间的X射线共晶体结构和DPP-4。根据这些X射线共晶体学结果,为了获得更强的抑制活性,我们将Arg125定位为潜在的氨基酸残基,因为它位于吡啶核附近,并且据报道一些已知的DPP-4抑制剂与该残基相互作用。我们假设Arg125的胍基可以双齿方式与两个氢键受体相互作用。因此,我们设计了一系列3-吡啶基乙酰胺衍生物,它们具有一个额外的氢键受体,可以与Arg125发生所需的二齿相互作用。我们发现了1-[5-(氨基甲基)-2-甲基-4-(4-甲基苯基)-6-(2-甲基丙基)吡啶-3-基]乙酰基} -1-脯氨酰胺的二盐酸盐(13j)是一种有效且选择性的DPP-4抑制剂,可以以独特的双齿方式与Arg125的胍基相互作用。
