Molecular docking is a computational technique used to predict the preferred orientation of a ligand when bound to a receptor protein, helping researchers understand molecular interactions and aiding drug discovery. This method allows scientists to estimate binding affinities and identify potential drug candidates.

The concept of molecular docking was first explored by Irwin “Win” Kuntz in 1970, who pioneered computational approaches to predict ligand binding to receptors, laying the foundation for modern computer-aided drug design. His early work demonstrated that in silico predictions could complement experimental studies and accelerate drug discovery research.

By the end of this lecture, you’ll have the skills to confidently analyze docking results and clearly present your findings for research, academic, or professional use.

In this lecture, you will learn how to perform docking experiments using CB-Dock2, a free and user-friendly web-based tool for cavity detection and binding site prediction. We will explore how to upload receptor and ligand files, automatically identify potential binding pockets, and run docking simulations directly online without complex installations.

You’ll also learn how to interpret the docking scores, compare different binding sites, and download results for further visualization in tools like Discovery Studio. By the end of this lecture, you’ll be able to confidently use CB-Dock2 to complement your docking studies and enhance your research workflow with quick, reliable web-based predictions.
