designed, synthesized, and studied on the antiviral and antifungal activities. Most of these compounds displayed higher antiviral activities than ribavirin. The antiviral activities of compounds 1a and 13e–13h are similar to or higher than that of ningnanmycin (perhaps the most efficient anti-plant-virus agent). Compound 13h was selected for further antiviral mechanism research via transmission electron
随着植物病害的日益严重和病原体抗性的出现,迫切需要开发新型高效、环保的农药。海洋天然产物(MNP)资源丰富多样。基于 MNP 的结构简化是寻找新型农药候选物的重要策略。在这项工作中,海洋天然产物 6"-debromohamacanthin A ( 1a ) 被有效地制备并选择为母体结构。设计、合成了一系列金黄素衍生物,并研究了其抗病毒和抗真菌活性。大多数这些化合物显示出比利巴韦林更高的抗病毒活性。化合物1a和13e – 13h的抗病毒活性与宁南霉素(可能是最有效的抗植物病毒剂)相似或更高。通过透射电子显微镜、分子对接和荧光滴定,选择化合物13h进行进一步的抗病毒机制研究。结果表明,化合物13h可与TMV CP结合,干扰TMV CP与RNA的组装过程。此外,这些金黄素衍生物还对八种常见的农业病原体表现出广谱抑制作用。化合物1a、12b和12f具有优异的杀菌活性,可作为新的杀菌候选物进行进一步
