Virtual Screening (VS) is a screening of active compounds based on small molecule databases. Using the molecular docking operation between small molecule compounds and drug targets, virtual screening can quickly select active compounds with druggability from tens to millions of molecules, greatly reducing the number of experimental screening compounds, shortening the research period, and reducing the cost of drug development cost. According to reports, the positive rate of virtual screening is 5%-30%, and the number of successful use of virtual screening to assist drug design is increasing year by year, and virtual screening has become the most promising drug development tool. The bioinformatician of ComputaBio is proud to tell you that we are willing to provide you with virtual screening services!

Virtual screening methods are mainly divided into two types: structure-based virtual screening (SBVS) and ligand-based virtual screening (LBVS).
Receptor-based virtual screening is virtual screening based on molecular docking. It is based on the experimentally determined or homologously modeled three-dimensional structure of receptor biological macromolecules. Through molecular docking, the binding conformation of small molecules and receptors is determined. According to the affinity scoring function related to the binding energy, the binding ability of proteins and small molecule compounds is evaluated, and finally a compound with a reasonable binding mode and a higher prediction score is selected from a large number of compound molecules for subsequent biological use. Activity test.
Ligand-based virtual screening is virtual screening based on pharmacophore models. It is based on the analysis of the structure, physicochemical properties and activity relationships of existing drugs to establish a quantitative structure-activity relationship or pharmacophore model to predict the activity of screening new compounds.
