as a lead for future insecticides development. Modeling the ligand−receptor complexes by molecular docking study explained the structure−activity relationships observed in vitro and revealed an intriguing molecular binding mode at the active site of the nAChR model, thereby possibly providing some useful information for future receptor structure-based designs of novel insecticidal compounds.
设计并制备了两个系列的新亚硝基新烟碱类似物(2a - 2h和3a - 3h),并通过X射线衍射证实了其顺式构型。初步的生物分析表明,大多数类似物在500 mg / L时表现出优异的杀虫活性,而具有光学活性(2c - 2g)的类似物在100 mg / L时具有很高的效力,而化合物2d在20 mg / L时具有90%以上的死亡率,这表明它可以用作未来杀虫剂开发的先导。通过分子对接研究对配体-受体复合物进行建模,解释了体外观察到的结构-活性关系,并揭示了nAChR模型活性位点上有趣的分子结合模式,从而可能为将来基于新型受体结构的设计提供一些有用的信息。杀虫化合物。
