mL−1. Both compounds 19 and 25 exhibited broad-spectrum fungicidal activity (>50% inhibitory activities against 13 phytopathogenic fungi), which were better than those of the commercial pesticide pyrimethanil (>50% inhibitory activities against eight phytopathogenic fungi). Furthermore, compounds 19 and 25 exhibited protective activity against Sclerotinia sclerotiorum on leaves of Brassica oleracea L
为了寻找具有杀虫和抗真菌活性的农药,设计并合成了一系列新型苯甲酰

生物。所有目标化合物均通过 1 H-NMR 光谱和 HRMS 进行鉴定。评估了这些化合物的杀虫和抗真菌活性,并清楚而全面地说明了构效关系 (
SAR)。化合物 7 对斑马鱼的毒性较低(LC50 = 378.387 µg mL − 1),浓度为 0.25 µg mL − 1 时对蚊子(淡色库蚊)有 100% 的抑制作用。化合物19和25均表现出广谱杀菌活性(对13种植物病原真菌的抑制活性> 50%),优于商业农药
嘧霉胺(对8种植物病原真菌的抑制活性> 50%)。此外,
