Enterovirus A71 (EV-A71), one of the major pathogens that causes hand, foot and mouth disease (HFMD), has seriously threatened the health and safety of young children. In this study, aminothiazole derivatives were synthesized and screened against EV-A71 in Rhabdomyosarcoma (RD) cells. The best compound (12s), with a biphenyl group, showed activity against EV-A71 (EC50: 0.27 μM) but also against a series
肠道病毒 A71 (EV-A71) 是导致手足口病 (HFMD) 的主要病原体之一,严重威胁幼儿的健康和安全。在这项研究中,合成了氨基噻唑衍生物,并在横纹肌肉瘤 (RD) 细胞中针对 EV-A71 进行了筛选。最好的化合物 ( 12 s ),带有一个联苯基,对 EV-A71 (EC 50 : 0.27 μM) 显示出活性,而且对一系列不同的人类肠道病毒也没有显着的细胞毒性 (CC 50 > 56.2 μM)。包括药物添加时间测定、病毒进入测定和微量热泳 (MST) 实验在内的机制研究表明,12 s与 EV-A71 衣壳结合并阻断病毒蛋白 VP1 与相关的人类清道夫受体 B 类成员 2 (hSCARB2) 之间的结合。
