was superior to those of commercial fungicides hymexazol and chlorothalonil. Furthermore, compound 5 b could completely suppress the spore germination of V. mali at a concentration of 10 μg/mL. Finally, molecular docking revealed that the potential target for the antifungal activity of compound 5 b was succinate dehydrogenase (SDH). This research provides novel candidate compounds for the prevention
设计并合成了四个系列的新型1,3,4-恶二唑/1,2,4-三唑杂化苯并呋喃衍生物,以寻找新型潜在的抗真菌剂。初步抗真菌活性测定结果表明,化合物4a 、 4b 、 4m 、 5b 、 5f 、 5h和7h对一些植物病原真菌表现出中等至优异的抑制活性。其中,化合物5b对苹果曲霉和核盘菌的抗真菌作用最为突出,EC 50平均值分别为3.96 μg/mL和5.60 μg/mL,优于市售杀菌剂恶霉唑和百菌清。 。此外,化合物5b在10μg/mL的浓度下可以完全抑制苹果弧菌孢子的萌发。最后,分子对接揭示化合物5b抗真菌活性的潜在靶点是琥珀酸脱氢酶(SDH)。这项研究为预防植物病原真菌提供了新的候选化合物。
