In this study, we reported the synthesis and biological characterization of a novel series of furan-carboxamide derivatives that were potent inhibitors of the influenza A H5N1 virus. The systematic structure–activity relationship (SAR) studies demonstrated that the 2,5-dimethyl-substituted heterocyclic moiety (furan or thiophene) had significant influence on the anti-influenza activity. In particular
在这项研究中,我们报道了一系列新型的呋喃甲酰胺衍生物的合成和生物学特性,这些衍生物是甲型H5N1流感病毒的有效抑制剂。系统的结构-活性关系(SAR)研究表明,2,5-二甲基取代的杂环部分(呋喃或噻吩)对抗流感活性具有重要影响。特别地,2,5-二甲基-N-(2-(((4-硝基苄基)硫代)乙基)-呋喃-3-羧酰胺1a显示出对H5N1病毒的最佳活性,其EC 50值为1.25μM。首次将简单的支架呋喃-羧酰胺衍生物鉴定为致命的H5N1甲型流感病毒的新型抑制剂。
