the discovery and development of natural products‐based fungicides, a series of thirty‐one sarisan attached 3‐phenylisoxazolines were synthesized and evaluated for their antifungal activities against five phytopathogenic fungi (B. cinerea, C. lagenarium, A. solani, F. solani, and F. graminearum). Among all title sarisan derivatives, compounds IV2, IV14 and IV23 showed potent antifungal activity against
许多植物病原真菌对作物产量造成严重损害。为了继续我们旨在发现和开发基于天然产物的杀菌剂的研究,合成了一系列 31 种附着有 3-苯基异恶唑啉的纱丽,并评估了它们对五种植物病原真菌(B. cinerea、C. lagenarium、 A. solani、F. solani 和 F. graminearum)。在所有标题 sarisan 衍生物中,化合物 IV2、IV14 和 IV23 对某些植物病原真菌显示出有效的抗真菌活性。特别是,化合物 IV2 表现出比商业杀菌剂 Hymexazol 更广谱和更有效的抗病曲霉、茄病镰刀菌和禾谷镰刀菌的抗真菌活性。此外,化合物IV2、IV14和IV23对正常NRK-52E细胞的毒性也相对较低。
