Virtual screening (VS) is a computational technique used in drug discovery research. By using computers, it deals with the quick search of large libraries of chemical structures in order to identify those structures which are most likely to bind to a drug target, typically a protein receptor (biochemistry)|receptor or enzyme. Virtual screening has become an integral part of the drug discovery process. Related to the more general and long pursued concept of database searching, the term virtual screening is relatively new. Walters, et al. define virtual screening as automatically evaluating very large libraries of compounds using computer programs. As this definition suggests, VS has largely been a numbers game focusing on questions like how can we filter down the enormous chemical space of over 1060 conceivable compounds to a manageable number that can be synthesized, purchased, and tested. Although filtering the entire chemical universe might be a fascinating question, more practical...
