持久性有机污染物4,4’-DDE和CB-153的反向虚拟筛选

持久性有机污染物(POPs)会导致人类和动植物各种疾病的发生,已经成为一种新的全球性环境问题.研究发现,POPs分子能够特异性地结合到生物体内一些蛋白质受体上,发挥其致病机制.本文运用基于分子对接的反向虚拟筛选方法,从蛋白质结构数据库中筛选出配体分子可能的受体蛋白质,研究了持久性有机污染物4,4’-DDE和CB-153潜在的受体蛋白质.结合实验信息,讨论分析了排在前5%的蛋白质受体.值得注意的是,已知的一些蛋白质受体都排在了虚拟筛选结果的前列.该研究不仅有助于进一步了解这些有毒污染物分子的致病机制,还将为设计针对该类污染物分子的生物传感器提供有用的信息....

Persistent organic pollutants (POPs) cause various diseases in both human and wildlife and have become a new global environmental problem. The toxic effects of POPs can be induced through their binding to specific proteins in the body. In the present work, a reverse virtual screening method based on molecular docking was used to search for potential protein targets for two POPs, 4,4'-dichlorodiphenyldichloroethane (4, 4'-DDD) and 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153), from a protein structure database. Targets ranked in the top 5% were chosen for analysis using experimental information. All known targets appeared in the top 5% of targets. This study not only increases understanding of the toxic mechanism of POPs, but may also aid the design of novel recognition elements in biosensors.
