Neuraminidase (NA) is an effective target for research and development of anti-influenza drugs. Herein, based on structure-based virtual screening, it was found that ZINC05250774, an oxalamide derivative, was a lead NA inhibitor. In this paper, a series of novel inhibitors (Z1–Z10) were designed and synthesized through modification and transformation of ZINC05250774. From the inhibition results, compound
神经氨酸酶(NA)是抗流感药物研发的有效靶点。在此,基于基于结构的虚拟筛选,发现草酰胺衍生物ZINC05250774是一种先导 NA 抑制剂。本文通过对ZINC05250774的修饰和转化,设计合成了一系列新型抑制剂( Z1-Z10 ) 。从抑制结果来看,化合物Z2对NA的抑制活性最好(IC 50 = 0.09 μM),优于阳性对照羧酸奥司他韦(OSC)(IC 50 = 0.10 μM)和铅ZINC05250774(IC 50 )= 1.91 微米)。分子对接结果表明Z2的良好效力可能归因于3-氯取代的苯基,其可以通过草酰胺链延伸到430-腔中。此外,草酰胺基团对于这一系列化合物也很重要,它可以在活性位点与三个必需的带正电荷的精氨酸残基(Arg118、Arg292 和 Arg371)形成强氢键相互作用。这项工作的结果可能有助于开发更有效的 NA 抑制剂来对抗流感病毒。
