Virtual Screening Service

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. The positive rate of VS has been reported to be 5%-30%, and the number of successful use of VS to assist drug design is increasing annually, making VS the most promising drug development tool. CD ComputaBio is proud to provide the most efficient and accurate virtual screening services to our clients.

Process of our virtual screening services

Virtual screening methods are mainly divided into two types: structure-based virtual screening (SBVS) and ligand-based virtual screening (LBVS).

• SBVS receptor-based virtual screening

Receptor-based virtual screening is virtual screening based on molecular docking. It uses an 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.

• LBVS ligand-based virtual screening

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.
