Virtual screening (VS) and chemical data extracted from evidence based sources are the backbone of computational drug discovery workflow, an indispensable component in all drug design programs. It involves a host of modelling techniques from simple similarity search methods to advanced algorithms for finding the accurate bioactive conformation of a molecule to bind to its corresponding target. Chemoinformatics supports virtual screening at multiple levels during the lead optimization stage by suggesting suitable filters for numerous screenings by utilizing the power of data integration from multiple sources and derived knowledge that is essential for decision support in drug discovery and development. It is therefore pertinent to develop tools, data and emerging methods in chemoinformatics to fully understand their role and applications in virtual screening. Recently we have developed chemical informatics tools to assist drug discovery by chemical data extraction from literature, virtual library design, analysis and screening methods on selected case studies.
