Thirty-five novel chromone derivatives containing dithioacetal moiety were designed, synthesized, and their anti-TMV activities were evaluated through half-leaf method. The results showed compound c23 illustrates highly curative, protective and inactivating activities against TMV at 500 mg/L, with the values of 68.8%, 58.8%, 86.0% respectively, which were superior to that of Ribavirin (42.3%, 49.8%
设计合成了二十五种含二硫缩醛部分的色酮衍生物,并通过半叶法评价了它们的抗TMV活性。结果表明,化合物c23对500 mg / L的TMV具有很高的治愈,保护和灭活活性,其值分别为68.8%,58.8%,86.0%,优于利巴韦林(42.3%,49.8%,68.4)分别为%和宁南霉素(分别为59.4%,52.4%,88.4%)。化合物c23的灭活活性EC50值为9.3 mg / L,优于利巴韦林(135.2 mg / L),与宁南霉素(8.8 mg / L)相当。此外,化合物c23可以破坏TMV-CP的完整性,导致TMV的传染性降低。同时,化合物c23可与TMV蛋白涂层结合并水解TMV蛋白涂层,影响TMV的自组装过程,缔合常数(Kd)为4.5 mg / L。这一发现表明,含有二硫缩醛部分的色酮衍生物可以用作新的抗病毒剂。
