designed and synthesized a series of novel mesoionic compounds that exhibited a range of insecticidal activities against A. craccivora. The LC50 values of compounds E1 and E2 were 0.73 and 0.88 μg/mL, respectively, better than triflumezopyrim (LC50 = 2.43 μg/mL). Proteomics and molecular docking analyses showed that E1 might influence the A. craccivora nervous system by interacting with neuronal nicotinic
豆蚜 ( Aphis craccivora ) 对常用杀虫剂的抗性使得控制这些害虫变得越来越困难。在这项研究中,我们通过支架跳跃策略将具有杀虫活性的异恶唑和异恶唑啉引入吡啶并[1,2- a ]嘧啶酮中。我们设计并合成了一系列新型中离子化合物,这些化合物对A. craccivora表现出一系列杀虫活性。化合物E1和E2的LC 50值分别为0.73和0.88 μg/mL,优于氟嘧啶(LC 50 = 2.43 μg/mL)。蛋白质组学和分子对接分析表明E1可能影响A. craccivora神经系统通过与神经元烟碱乙酰胆碱受体 (nAChRs) 相互作用。这项研究为开发新型中离子杀虫剂提供了一种新方法。
