Zika virus (ZIKV), an arbovirus of the Flaviviridae family, has emerged as a significant public health concern owing to its association with congenital abnormalities and severe neurological sequelae. Thus, there is an urgent need to develop effective therapeutic approaches to efficiently treat ZIKV infections. This study used phenotypic screening to identify a series of 1,2,4-oxadiazole derivatives that possess antiviral activity against ZIKV infection. Subsequently, 28 new derivatives were designed, synthesized, and evaluated for this purpose. Among these compounds, 4-(5-phenyl-1,2,4-oxadiazol-3-yl)-N-(pyridin-3-ylmethyl)aniline (5d) had potent antiviral activity against ZIKV infections. Furthermore, a structure–activity relationship analysis indicated that a benzyl substitution on the aniline nitrogen of this compound improved potency while augmenting its drug-like properties. In addition, 5d exhibited antiviral activity against various viruses of Flaviviridae family of worldwide public health importance, such as dengue, Japanese encephalitis and classical swine fever viruses, indicating its potential as a lead compound for generating 1,2,4-oxadiazole derivatives with broad-spectrum anti-flaviviral properties.
寨卡病毒(ZIKV)是黄病毒科的一种虫媒病毒,由于与先天性畸形和严重的神经系统后遗症有关,已成为一个重大的公共卫生问题。因此,迫切需要开发有效的治疗方法来有效治疗 ZIKV 感染。本研究利用表型筛选鉴定了一系列具有抗 ZIKV 感染病毒活性的 1,2,4-恶二唑衍生物。随后,为此目的设计、合成和评估了28种新的衍生物。在这些化合物中,4-(5-苯基-1,2,4-恶二唑-3-基)-N-(吡啶-3-基甲基)苯胺(5d)对寨卡病毒感染具有有效的抗病毒活性。此外,结构-活性关系分析表明,该化合物苯胺氮上的苄基取代提高了效力,同时增强了其药物样特性。此外,5d 对对全球公共卫生具有重要意义的黄病毒科多种病毒(例如登革热、日本脑炎和猪瘟病毒)表现出抗病毒活性,表明其作为先导化合物用于生成具有广泛作用的 1,2,4-恶二唑衍生物的潜力。 -广谱抗黄病毒特性。
