showed good to excellent insecticidal activities against the oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). For the oriental armyworm, Ij displayed the same level of larvicidal activity as the positive control chlorantraniliprole, with an LC50 value of 0.21 mg/L. For the diamondback moth, In, Io, Ip, and Iq exhibited higher insecticidal activities than chlorantraniliprole
为了应对全球粮食短缺和虫害,迫切需要发现具有新颖作用方式的新型农药。Ryanodine受体(RyR)杀虫剂在病虫害综合治理中显示出广阔的前景。在本文中,我们报道了结合针对昆虫RyRs的吡咯部分的新型邻氨基苯甲酰胺衍生物的合成。通过1 H NMR,13 C NMR,19 F NMR和高分辨率质谱确认结构。初步的生物测定结果表明,大多数标题化合物对东方粘虫(Mythimna separata)和小菜蛾(Plutella xylostella)表现出良好的杀虫活性。对于东方粘虫,Ij表现出与阳性对照氯扑兰酯相同的杀幼虫活性,LC 50值为0.21 mg / L。对于小菜蛾,In,Io,Ip和Iq的杀虫活性高于氯氰菊酯。特别地,In在0.00001mg / L下具有50%的杀幼虫活性。钙成像技术用于研究Ij,In和Ip对细胞内钙离子浓度([Ca 2+ ] i)分离自东方粘虫的中枢神经元。结果表明,
