Several methods were developed in the past decades to deal with this issue,īut a general and successful approach is still missing.

Regarding their complexes with the target protein is not always available. The search for new drug candidates, for which experimental information Generally in the shape of the binding site. Which induces at least changes in the orientation of side chains and more Issue in presence of significant structural changes of the protein receptorĭue to the interaction with ligands (mechanism known as induced fit , The sampling problem, which is the focus of the present tutorial, is a crucial To sample conformations of the binding site in the presence of ligands and theĭifficulties associated to correctly account for entropic and de-solvationĬontributions in the scoring functions. Examples of these limitations include the reduced ability However, they are both subject to failures due to the intrinsic limitations ofĭocking algorithms. Both the above tasks i) and ii) can be implemented in different ways, Ones, thus assigning them the highest score (i.e. Ĭlearly, a VS calculation should correctly rank native-like poses as the top The main computational method employed in virtual screening (VS) campaignsĪiming to the identification of putative drug candidates in silico.

A docking algorithmĬan be grossly split into two main tasks: i) the search for putative binding poses of the ligand onto the selected protein target(s) ii) the ranking of all generated poses, according to a given “scoring function” which should reproduce at best the free energy of binding of the complex. The cost associated with the development of new drugs. Molecular docking is a widely used techniqueĮmployed in Computer-Aided Drug Design with the aim to drastically reduce Namely metadynamics to improve the predictive power of molecularĭocking of small ligands to a protein target in the framework of anĮnsemble docking strategy. In this tutorial we will exploit enhanced sampling molecular dynamics,
