摘要/Abstract

摘要： 基于埃博拉病毒跨膜单链糖蛋白（single glycoprotein of ebolavirus，EBOV-sGP）为靶标，运用类药性评估、分子对接、ADME预测、结合自由能计算、分子动力学模拟等计算机虚拟筛选技术，从中药数据库TCMSP中挖掘抗病毒天然产物活性分子。以药效分子托瑞米芬（toremifene）为阳性对照，最终筛选出4个类药性良好的先导化合物MOL006834、MOL000174、MOL002192、MOL012524，它们与EBOV-sGP亲和力及相互作用基团均接近于toremifene。该研究结果可促进从中药天然产物库中提取、设计以及实验合成抗埃博拉病毒的药效分子。

Abstract:

In this study,ebolavirus single glycoprotein of ebolavirus (EBOV-sGP) was used as the target,using diverse virtual screening technologies,such as drug-like evaluation,molecular docking,ADME prediction,binding free energy calculation,molecular dynamics simulation,etc.,in order to mine potential antiviral natural products from the database of traditional Chinese medicine.Taking toremifene as a positive control,four lead compounds,MOL006834,MOL000174,MOL002192,and MOL012524 with good drug-like properties were finally sorted.Their affinity values and interaction groups with EBOV-sGP are close to or similar to toremifene.The research results can promote the work of extracting,designing and experimentally synthesizing anti-ebolavirus compounds from natural products library of traditional Chinese medicine.

Key words: ebolavirus, Chinese natural products, antiviral active molecule, virtual screening, molecular dynamic simulation
