Identifying potential protein targets for a small-compound ligand query is crucial to the process of drug development. However, there are tens of thousands of proteins in human alone, and it is almost impossible to scan all the existing proteins for a query ligand using current experimental methods. Recently, a computational technology called docking-based inverse virtual screening (IVS) has attracted much attention. In docking-based IVS, a panel of proteins is screened by a molecular docking program to identify potential targets for a query ligand. Ever since the first paper describing a docking-based IVS program was published about a decade ago, the approach has been gradually improved and utilized for a variety of purposes in the field of drug discovery. In this article, the methods employed in docking-based IVS are reviewed in detail, including target databases, docking engines, and scoring function methodologies. Several web servers developed for non-expert users are also reviewed. Then, a number of applications are presented according to different research purposes, such as target identification, side effects/toxicity, drug repositioning, drug-target network development, and receptor design. The review concludes by discussing the challenges that docking-based IVS needs to overcome to become a robust tool for pharmaceutical engineering.
识别小分子配体查询的潜在蛋白质靶点对于药物开发过程至关重要。然而,仅人类体内就有成千上万种蛋白质,使用当前的实验方法对所有现有蛋白质进行查询配体扫描几乎是不可能的。最近,一种名为基于对接的反向虚拟筛选(IVS)的计算技术引起了广泛关注。在基于对接的IVS中,通过分子对接程序筛选一组蛋白质,以识别查询配体的潜在靶点。自从大约十年前发表第一篇描述基于对接的IVS程序的论文以来,该方法已逐渐得到改进,并在药物发现领域用于各种目的。在本文中,将详细回顾基于对接的IVS中使用的方法,包括目标数据库、对接引擎和评分函数方法。还将回顾为非专业用户开发的几个网络服务器。然后,根据不同的研究目的介绍一些应用,如靶点识别、副作用/毒性、药物重新定位、药物-靶点网络开发和受体设计。本文通过讨论基于对接的IVS要成为药物工程的强大工具需要克服的挑战来结束综述。
