In order to find novel and environmental friendly insecticides targeting the ryanodine receptor, three series of novel phthalamides containing heptafluoroisopropyl group, low fluorine atoms group and non-fluorine group were designed and synthesized. 35 novel structures of three series were obtained. Insecticidal activities of title compounds against oriental armyworm (Mythimna separata) and diamondback
为了找到针对ryanodine受体的新型环保杀虫剂,设计并合成了含有七氟异丙基,低氟原子基团和非氟基团的三组新型邻苯二甲酰胺。获得了三个系列的35个新颖结构。标题化合物对东方粘虫(Mythimna separata)和小菜蛾(Plutella xylostella)的杀虫活性表明,大多数标题化合物在测试浓度下均表现出中等至高活性。详细讨论了构效关系(SAR)。在合成标题化合物B 8,C 7,D 1,D时如图9和D 12所示,提供它们相应的位置异构体( B 8 ', C 7 ', D 1 ', D 9 '和D 12 '),并通过2D NMR确认其结构。钙成像技术还用于研究化合物B 2, B 10, C 4和C 5对细胞内钙离子浓度([Ca 2+ ] i),这表明它们从内质网释放了储存的钙离子,这表明某些化合物可能是昆虫瑞丹素受体(RyR)的潜在调节剂。
