A number of chromone derivatives containing sulfonamide structure were designed and synthesized. Firstly, the target compounds were evaluated for anti-TSWV activities in vivo by the half-leaf method. We found that most of the compounds had good anti-TSWV activities. Among them, compound 12B had excellent anti-TSWV inactivating activity with an EC50 of 80.5 μg/mL, which was significantly better than
设计合成了多种含有磺酰胺结构的色酮衍生物。首先,通过半叶法评估目标化合物的体内抗TSWV活性。我们发现大多数化合物具有良好的抗 TSWV 活性。其中,化合物12B具有优异的抗TSWV灭活活性,EC 50为80.5 μg /mL,明显优于香草六索冰米(765.7 μg /mL)。其次,表达和纯化TSWV核衣壳蛋白(N),并通过微量热泳(MST)测试化合物与TSWV N的亲和力。化合物12B对 TSWV N 具有良好的亲和力,K d值为 5.02 μ M,优于香草柳索冰米(29.83 μ M)。最后,为了研究化合物12B与TSWV N之间的相互作用方式,我们进行了分子对接。结果表明,化合物12B可能通过破坏TSWV N寡聚体结构来灭活病毒。这些结果为进一步发现具有高抗TSWV活性的含磺酰胺结构的色酮衍生物奠定了坚实的基础。
