associated with conventional insecticides and to search for potent insecticides targeting at ryanodine receptor (RyR), a series of novel anthranilic diamides containing N-substitued nitrophenylpyrazole were designed and synthesized. The insecticidal activities of target compounds against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella) were evaluated in our greenhouse by bio-assay
为了应对发展中的害虫抗性和与常规杀虫剂相关的生态问题,并寻找针对瑞丹定受体(RyR)的有效杀虫剂,设计并合成了一系列新型的含有N取代的硝基苯基吡唑的邻氨基苯甲酰胺。通过生物测定试验评价了目标化合物对东方粘虫(Mythimna separata)和小菜蛾(Plutella xylostella)的杀虫活性,并简要讨论了其相对的构效关系。大多数化合物均表现出中等至高活性,其中G 7和K 5对东方粘虫和K 2具有高活性。和K 4对抗小菜蛾的效果甚至优于对照氯虫腈。钙成像技术用于研究几种典型标题化合物对[Ca 2+ ] i的影响,尤其是G 7对神经元细胞内钙离子浓度([Ca 2+ ] i)的影响,这表明:一些标题化合物是RyR的有效激活剂。
