20-hydroxyecdysone. Because synthetic EcR ligands disrupt the normal growth of insects, they are attractive candidates for new insecticides. In this study, the Molecular Mechanics/Poisson-Boltzmann Surface Area (MM/PBSA) method was used to predict the binding activity of EcR ligands. Validity analyses using 40 known EcR ligands showed that the binding activity was satisfactorily predicted when the ligand conformational
蜕皮激素受体(EcR)是一种昆虫蜕皮受体,被蜕皮激素20-羟基蜕皮激素激活。由于合成的EcR配体破坏了昆虫的正常生长,因此它们是新型杀虫剂的诱人候选物。在这项研究中,使用分子力学/泊松玻尔兹曼表面积(MM / PBSA)方法来预测EcR配体的结合活性。使用40种已知EcR配体的有效性分析表明,当引入配体构象自由能术语时,可以令人满意地预测结合活性。随后,将此MM / PBSA方法应用于基于结构的分层虚拟筛选,并从380万种化合物的数据库中选择了12种候选化合物。这些化合物中的五个在基于细胞的竞争性结合测定中具有活性。
