To explore the novel compounds with high antiviral activity, three series ferulic acid derivatives containing amide moiety were gradually designed and synthesized based on antiviral activity tracking. The bioassay results exhibited that some target compounds had notable antiviral activities against tomato spotted wilt virus (TSWV) and cucumber mosaic virus (CMV). Compounds Y1, Y2, Y8, Z1 and Z2 presented
为了探索具有高抗病毒活性的新型化合物,基于抗病毒活性追踪,逐步设计和合成了三个系列含有酰胺部分的阿魏酸衍生物。生物测定结果表明,一些目标化合物对番茄斑枯病病毒(TSWV)和黄瓜花叶病毒(CMV)具有显着的抗病毒活性。化合物Y1、Y2、Y8、Z1和Z2在500 μg/mL时对TSWV和CMV表现出极好的治疗、保护和灭活活性。特别是,这些化合物与 EC 50对 TSWV 显示出出色的灭活效果值分别为 225.9、126.1、224.6、216.1 和 147.3 μg/mL,优于宁南霉素(249.1 μg/mL)和利巴韦林(315.7 μg/mL)。此外,通过进行微尺度热泳实验和分子对接实验,研究了化合物Y2的抗病毒机制。结果表明,化合物Y2对TSWV外壳蛋白(TSWV CP)具有优异的结合亲和力,结合常数为2.14 μM,这是由于化合物Y2与TSWV CP的关键氨基酸ARG94具有两个强氢键
