the plasmodial type II fatty acid synthesis II (FAS II) pathway, is a promising target for liver stage malaria infections. Hence, pfENR inhibitors have the potential to be used as causal malarial prophylactic agents. In this study, we report the design, synthesis, structural characterization and evaluation of a new class of pfENR inhibitors. The search for inhibitors began with a virtual screen of the
最近的研究表明,疟原虫烯醇基ACP还原酶(pf ENR,FabI)是疟原虫II型脂肪酸合成II(FAS II)途径中的关键酶之一,是肝阶段疟疾感染的有希望的靶标。因此,pf ENR抑制剂具有用作因果疟疾预防剂的潜力。在这项研究中,我们报告了新型pf ENR抑制剂的设计,合成,结构表征和评估。通过分子对接,从iResearch数据库的虚拟屏幕开始寻找抑制剂。从虚拟屏幕中获得的匹配数据根据其Glide得分进行排名。选择了一个匹配项作为线索,并对其进行了改进以提高其与pf ENR; 由此,设计并合成了一系列苯氨基乙酸亚苄基酰肼。这些分子通过IR,1 H,13 C,15 N,2D-NMR(COSY,NOESY,1 H- 13 C,1 H- 15 N HSQC和HMBC)和X射线衍射进行了彻底表征。NMR研究表明,酰胺和亚胺官能团周围存在构象/构型异构体。DMSO溶液中的主要物质是E,E形式,它与Z
