high activity, broad spectrum and low-toxicity, 17 benzamides substituted with quinoline-linked 1,2,4-oxadiazole were designed using the splicing principle of active substructures and were synthesized. The biological activities were evaluated against 10 fungi, indicating that some of the synthetic compounds showed excellent fungicidal activities. For example, at 50 mg/L, the inhibitory activity of 13p
为开发具有高活性、广谱、低毒的新化合物,利用活性亚结构的剪接原理,设计合成了17种喹啉连接的1,2,4-恶二唑取代的苯甲酰胺。对 10 种真菌的生物活性进行了评估,表明一些合成化合物表现出优异的杀菌活性。如50 mg/L时,13 p (3-Cl-4-Cl取代,86.1%)对核盘菌的抑制活性优于喹氧芬(77.8%),13f(3 -CF 3取代,77.8%)与喹氧芬相当。13 f的杀菌活性和13 p 对核盘菌的影响优于喹氧芬(14.19 mg/L),EC 50分别为6.67 mg/L和5.17 mg/L。此外,13 p的急性毒性为19.42 mg/L,属于低毒化合物。
