a lead for future development. Modeling the inhibitor-nAChR complexes by molecular docking studies explained the structure–activity relationships observed in vitro, and revealed an intriguing molecular binding mode at the active site of nAChR, which raised the possibility that these analogues may arbitrate their insecticidal activity through a mechanism other than imidacloprid.
设计并合成了一系列新的1,5-二取代的1,3,5-六氢三嗪-2- N-亚硝基亚胺(4a - 4x)作为新型手性新烟碱类似物。通过X射线衍射进一步确定4n的单晶结构,并确认其S构型。初步生物测定表明,化合物4e,4k,4u,4v在100 mg / L时表现出优异的杀虫活性,而4k在10 mg / L时具有> 90%的死亡率,这表明它可以用作未来开发的线索。通过分子对接研究对抑制剂-nAChR复合物进行建模,解释了体外观察到的结构-活性关系,并揭示了在nAChR活性位点上有趣的分子结合模式,这增加了这些类似物可能通过其他机制仲裁其杀虫活性的可能性。比吡虫啉。
