Virtual drug screening is a computational technique used to identify small molecules with structures most likely to bind to a drug target. Virtual screening can be roughly divided into two broad categories: structure-based virtual screening (SBVS) and ligand-based virtual screening (LBVS).
SBVS is using the scoring function related to binding energy to evaluate and classify protein-ligand binding modes, from which a series of compounds with rational binding modes and high predicted scores are selected. The screening process is restricted by combining pharmacophore modeling and molecular dynamics (MD) simulations.
Ligand-based virtual screening methods use the information present in known active ligands rather than a target protein's structure for lead identification and optimization. Ligand-based methods are the only ones chosen when no 3D structure of the target protein is available.
