英文摘要: Discovery and optimization of the novel lead structure is the key bottleneck of novel pesticide research. Accelerating the speed of the lead structure discovering and optimizing can shorten the periods of novel pesticide development. On the basis of our previous study, the structurally diverse database will be built. The high-effect virtual screening based on the advanced QSAR and molecular docking methods will be carried out. And synthesis of novel ecdysone analogues and the biological activity validation between ligands and EcR/USP will be done. The aim is to find one or two lead compounds with high activity and novel structure. The whole research will carry on the cross-cooperation of computational chemistry, statistics, organic chemistry, pesticides and molecular biology and will benefit on the discovering of novel lead compound and give the theoretical guidance and potential practice value.
