of novel mesoionic pyrido[1,2-a]pyrimidinone compounds containing a natural skeleton indole were designed and synthesized, and the insecticidal activities of the target compounds were tested. The results showed that the target compounds had good to excellent insecticidal activities against white-backed planthoppers (Sogatella furcifera) and bean aphids (Aphis craccivora). Among them, compound 7 showed
本研究设计合成了一系列含有天然骨架吲哚的新型介离子吡啶并[1,2- a ]嘧啶酮类化合物,并测试了目标化合物的杀虫活性。结果表明,目标化合物对白背飞虱(Sogatella furcifera)和豆蚜(Aphis craccivora)具有良好至优异的杀虫活性。其中,化合物7对S. furcifera和A. craccivora均表现出优异的杀虫活性,LC 50值分别为0.86和0.85 μg/mL。对豆蚜( A. craccivora)的杀虫活性) 优于氟虫嘧啶 (LC 50 = 3.67 μg/mL)。蛋白质组学和定量实时聚合酶链反应 (qRT-PCR) 结果表明,化合物7可能与S. furcifera的 α1 和 α7 nAChR 亚基相互作用。酶活性结果表明,化合物7是S. furcifera中AChE的抑制剂。本研究为发现新型中离子吡啶并[1,2- a ]嘧啶酮类杀虫剂提供了新思路。
