H5N1 virus, one subtype of highly pathogenic influenza A virus in human infection, has recently received attention due to its unpredictable and high mortality. In this study, a series of arylsulfonamide derivatives were identified as improved H5N1 inhibitors for the influenza treatment by systematic structure-activity relationship investigation. Among them, the most potent H5N1 inhibitor 3h exhibited
H5N1病毒是人类感染中高致病性甲型流感病毒的一种亚型,最近由于其不可预测的高死亡率而受到关注。在这项研究中,通过系统的结构-活性关系研究,一系列芳基磺酰胺衍生物被确定为用于流感治疗的改良H5N1抑制剂。其中,最有效的H5N1抑制剂3h对H5N1病毒表现出优异的抗病毒活性,EC 50值为0.006μM,选择性指数为33543.3。此外,3h与M2质子通道蛋白的分子对接为理解这类化合物对H5N1的抑制提供了实用的方法。
