To explore novel molecules with unique mechanisms against plant pathogenic fungi, a series of phenylalanine derivatives containing a 1,3,4-oxadiazothioether moiety were designed and synthesized. Bioassays revealed that some target compounds at 100 μg/mL exhibited excellent antifungal activities against Thanatephorus cucumeris, such as G6 (92.1 %), G10 (94.3 %), G18 (99.1 %), and G19 (98.7 %), better
为了探索具有独特机制对抗植物病原真菌的新型分子,设计并合成了一系列含有 1,3,4-恶二偶氮硫醚部分的苯丙氨酸衍生物。生物测定表明,一些 100 μg/mL 的目标化合物表现出出色的抗南瓜的抗真菌活性,例如G 6 (92.1 %)、G 10 (94.3 %)、G 18 (99.1 %) 和G 19 (98.7 %),优于市售杀菌剂嘧菌酯(90.6%),G 10对黄瓜木霉的EC 50值为31.9 μg/mL。进一步的机制研究用G 10处理的黄瓜 T. cucumeris证明该化合物可以通过破坏膜的完整性来影响菌丝体的生长,并且该化合物的浓度越高,膜完整性的破坏程度越大,类似于商业杀菌剂嘧菌酯. 这些结论为进一步研究该系列苯丙氨酸衍生物的机理提供了重要信息。
