A class of novel myricetin derivatives containing 1,3,4-oxadiazole bisthioether were synthesized. The results of antiviral biological activity demonstrated that the partially compounds exhibited good antiviral effects against tobacco mosaic virus. The in vivo curative and protective activities of compound E12 against TMV was quite significant. The EC50 value of the curative activity of E12 was 128
合成了一类含有1,3,4-恶二唑二硫醚的新型杨梅素衍生物。抗病毒生物活性结果表明,部分化合物对烟草花叶病毒表现出良好的抗病毒作用。化合物E12对TMV的体内治疗和保护活性非常显着。E12的疗效EC 50值为128.8 μg/mL,而宁南霉素的值为296.4 μg/mL。同样, E12的保护活性的 EC 50值为99.1 μg/mL,而宁南霉素为307.6 μg/mL。微量热泳数据表明,宁南霉素与TMV-CP的结合值为2.726±1.301 μM,不如E12与TMV-CP的结合值为0.029±0.013 μM。本研究表明含有1,3,4-恶二唑二硫醚的新型杨梅素衍生物可能是一种极具潜力的农用抗病毒药物。
