designed and synthesized a series of novel 6-methyl-7-acetylenenyl-7-deazapurine nucleoside analogs as potential inhibitors of ZIKV replication. The biological activities against ZIKV replication were evaluated and the structure-activity relationship (SAR) was also studied. Among the compounds evaluated, nucleoside analog 38 (EC50 = 2.8 ± 0.8 μM, EC90 = 6.8 ± 2.3 μM) showed the most potent anti-ZIKV
寨卡病毒 (ZIKV) 是一种由蚊子传播的黄病毒,最近在非洲、美洲和世界其他地区报告了寨卡病毒的爆发。近年来,ZIKV 流行病因其能够引起严重的医疗后果和并发症,如小头畸形和格林-巴利综合征等而受到广泛关注。到目前为止,还没有针对 ZIKV 感染的特定治疗方法或疫苗,这凸显了开发新疗法的迫切需要。在这项工作中,我们设计并合成了一系列新型 6-甲基-7-乙炔基-7-脱氮嘌呤核苷类似物,作为 ZIKV 复制的潜在抑制剂。评估了针对 ZIKV 复制的生物活性,并研究了构效关系 (SAR)。在评估的化合物中,核苷类似物38(EC 50 = 2.8 ± 0.8 μM, EC 90 = 6.8 ± 2.3 μM ) 在基于 A549 的细胞模型中 显示出最有效的抗 ZIKV 活性和低细胞毒性 (CC 50 = 54.1 ± 6.9 μM)。38的抑制活性比阳性对照NITD008强约5倍。值得注意的是,在包括
