intracellular calcium ion concentration ([Ca2+]i) in neurons were concentration-dependent. After the central neurons of Helicoverpa armigera were dyed by loading with fluo-5N and treated with 12i, the free calciumreleased in endoplasmic reticulum indicated the target of compound 12i is RyRs or IP3Rs. The activation of RyRs by natural ryanodine completely blocked the calciumrelease induced by 12i
为了发现针对ryanodine受体(RyRs)的有效杀虫剂,设计并合成了一系列含有N-取代苯基吡唑的新型邻氨基苯甲酰胺二酰胺类似物(12a – 12u)。这些化合物通过1 H NMR,13 C NMR和HRMS进行表征,并且化合物12u的结构通过X射线衍射确认。它们的杀虫活性表明这些化合物显示出中等至优异的活性。特别是,12i在0.25和0.05 mg L –1时对东方粘虫(Mythimna separata)表现出100%和37%的杀幼虫活性,相当于对氯吡虫啉(100%,0.25 mg L )的杀幼虫活性。–1 ; 和33%,0.05 mg L –1)。12i对小菜蛾(Plutella xylostella)的活性在0.05 mg L –1时为95%,而对照在0.05 mg L –1时为100%。钙成像技术实验结果表明,12i对神经元细胞内钙离子浓度([Ca 2+ ] i)的影响与浓度有
