We identified and explored the structure–activity-relationship (SAR) of an adamantane carboxamide chemical series of Ebola virus (EBOV) inhibitors. Selected analogs exhibited half-maximal inhibitory concentrations (EC50 values) of ∼10–15 nM in vesicular stomatitis virus (VSV) pseudotyped EBOV (pEBOV) infectivity assays, low hundred nanomolar EC50 activity against wild type EBOV, aqueous solubility
我们确定并探索了埃博拉病毒(EBOV)抑制剂的金刚烷羧酰胺化学系列的结构-活性关系(SAR)。选定的类似物在水疱性口炎病毒(VSV)假型EBOV(pEBOV)感染性试验中显示出约10–15 nM的半数最大抑制浓度(EC 50值),对野生型EBOV的低百纳摩尔EC 50活性,水溶性> 20 mg / mL,并且在人和非人肝微粒体中具有诱人的代谢稳定性。含EBOV糖蛋白(GP)的先导化合物的X射线共晶体表征确定EBOV GP为直接化合物抑制活性的靶标,并进一步提供了相关结构模型,可帮助鉴定优化的治疗候选物。
