Chapter 1 Stakes and Initials From the large literature on cheminformatics, we must choose the few, not the many. Virtual Screening and Molecular Docking Computational Chemists face a dilemma: either we apply virtual screening to find all possible active ligands, or we look for a ligand of some specific interest.
In practice, we must often choose between exploring a large number of potential candidates or producing a promising lead molecule for further development. Much effort is directed toward developing a rapid method for assessing activity, from the affinity of a ligand toward its receptor or enzyme target to the potency of a molecule in a biological assay. Most ligand-based virtual screening methods use a single criterion for prioritizing the search to avoid an exponential increase in the number of potential ligands as the number of compounds increases (Muegge et al. However, no single metric is appropriate for all cases. Therefore, the goal of a ligand-based virtual screening program should be to develop a method that favors candidates that could progress to a successful drug product. To achieve this goal, a ligand-based virtual screening method must be supported by a rational, data-driven process in which a diverse set of chemical structures is introduced to the screening method and analyzed using a wide range of activity-related metrics. During the course of a drug discovery program, many promising compounds are discarded due to lack of available resources, a pharmacologically significant bioassay, or other reasons. Consequently, for any given drug discovery program, we must ask how much is being gained by the choices made in the early stages of the project, and how much can be improved by running additional rounds of screening. A corollary of this is that we must be careful to not build up a backlog of undiscovered scaffolds. A Virtual Library The success of a virtual screening program in finding molecules of therapeutic interest depends upon the balance between the speed and the quality of the results. The speed of the screen is ultimately limited by the speed of search algorithms, the power of the computer performing the search, the size of the library of known active compounds, and the availability of library resources.
The quality of the results is determined by the accuracy and completeness of the information contained in the library of known active compounds. In addition, molecules that do not bind to a target are not necessarily worthless: they may bind very weakly or to an allosteric site and still be useful as tools for investigating receptor biology. The quality of the results also depends on
