Enterovirus infections are common in humans, yet there are no approved antiviral treatments. In this study we concentrated on inhibition of one of the Enterovirus B (EV-B), namely Coxsackievirus A9 (CVA9), using a combination of medicinal chemistry, virus inhibition assays, structure determination from cryogenic electron microscopy and molecular modeling, to determine the structure activity relationships for a promising class of novel N-phenylbenzylamines. Of the new 29 compounds synthesized, 10 had half maximal effective concentration (EC50) values between 0.64–10.46 μM, and of these, 7 had 50% cytotoxicity concentration (CC50) values higher than 200 μM. In addition, this new series of compounds showed promising physicochemical properties and act through capsid stabilization, preventing capsid expansion and subsequent release of the genome.

新型柯萨奇病毒 A9 衣壳结合剂的 SAR 分析



肠道病毒感染在人类中很常见,但尚无批准的抗病毒治疗方法。在这项研究中,我们专注于抑制肠道病毒 B (EV-B) 之一,即柯萨奇病毒 A9 (CVA9),结合使用药物化学、病毒抑制测定、低温电子显微镜的结构测定和分子建模,以确定一类有前途的新型 N-苯基苄胺的结构活性关系。在合成的 29 种新化合物中,10 种化合物的半数最大有效浓度 (EC50) 值在 0.64–10.46 μM 之间,其中 7 种化合物的细胞毒性浓度 (CC50) 值高于 200 μM。此外,这一系列新化合物显示出有希望的物理化学性质,并通过衣壳稳定发挥作用,防止衣壳扩增和随后的基因组释放。
