To search a novel lead structure for antiphytopathogenic fungus agent, a series of novel psoralen derivatives possessing sulfonohydrazide or acylthiourea structure were designed and synthesized, and their fungicidal activity against seven phytopathogens was evaluated. Their structures were confirmed by melting points, 1H NMR, 13C NMR and HRMS, and the typical crystal structure was determined by X-ray
为了寻找抗植物病原真菌剂的新型先导结构,设计合成了一系列具有磺酰肼或酰基硫脲结构的新型补骨脂素衍生物,并评价了它们对七种植物病原体的杀真菌活性。它们的结构通过熔点、1 H NMR、13 C NMR和HRMS确定,典型的晶体结构通过X射线衍射确定以进行验证。初步杀真菌活性表明,一些标题化合物表现出一定至高的杀真菌活性。化合物I-13对Botrytis cinerea、Cercospora arachidicola和Physalospora piricola具有良好的杀真菌活性,具有 EC50 个值分别为 12.49、13.22 和 12.12 μg/mL。化合物II-9和II-15在体外显示出 50 μg/mL对B. cinerea的超过 90% 的抑制作用。特别是,II-9表现出显着更高的杀真菌活性,EC 50值为 9.09 μg/mL,低于阳性对照 YZK-C22 (13.41 μg/m
