countries. Currently, there are no approved drugs against the virus, and the development of anti-Zika virus drugs is thus urgent. The present investigation describes the discovery and hit expansion of a N-acyl-2-aminobenzothiazole series of compounds against Zika virus replication. A structure–activity relationship study was obtained with the synthesis and evaluation of anti-Zika virus activity and cytotoxicity
寨卡病毒感染与先天性小头畸形和寨卡热等严重疾病有关,对人类造成严重伤害,特别引起低收入国家卫生系统的关注。目前,尚无针对该病毒的批准药物,因此开发抗寨卡病毒药物刻不容缓。目前的研究描述了抗寨卡病毒复制的N-酰基-2-氨基苯并噻唑系列化合物的发现和命中扩展。通过合成和评价 19 种衍生物的抗寨卡病毒活性和对 Vero 细胞的细胞毒性,获得了构效关系研究。三种优化化合物的效力比初始化合物强 2.2 倍,选择性分别高 20.9、7.7 和 6.4 倍。随后进行表型和生化测定,以证明非结构蛋白(例如复合物 NS2B-NS3pro)是否与最活性化合物的作用机制有关。
