Neonicotinoid insecticides acting on the insect nicotinic acetylcholine receptors (nAChRs) play an essential role in contemporary pest control. In the present study, a series of novel neonicotinoid analogues with conjugated diene were synthesized. Bioassays indicated that compounds A3 and A12 had LC50 values of 1.26 and 1.24 mg/L against Myzus persicae, respectively, which were comparable to that of
作用于昆虫烟碱乙酰胆碱受体(nAChR)的新烟碱类杀虫剂在当代害虫防治中发挥着重要作用。在本研究中,合成了一系列具有共轭二烯的新型新烟碱类似物。生物测定表明,化合物A3和A12对桃蚜的LC 50值分别为1.26和1.24 mg/L ,与吡虫啉相当(IMI,LC 50 = 0.78 mg/L)。进行密度泛函理论(DFT)计算来解释目标化合物杀虫活性的差异。分子对接结果表明,化合物A3和A12与Lymnaea stagnalis AChBP 存在良好的相互作用。水解实验证实化合物A3和A12在水中的稳定性增强。
