Title : Improvements of computational optimization of drug-target interactions

Abstract:

Optimization of drug-target interactions is a central issue of structure-based drug design. There are fast docking methods available for calculation of the structure and energy of target-ligand complexes. Docking is the computational alternative of experimental structure determination methods such as X-ray crystallography, and it can help to reduce the costs of the drug discovery process. However, there are various limitations of computational docking such as inadequate input geometries of the target or the ligand, lack of convergence criteria during random search, inappropriate water models and force fields. The present lecture focuses on the problematics of water models. We show, how the correct prediction of hydration structure of target-ligand interfaces can help overcoming the above-mentioned various limitations of docking, and improve calculation of drug-target interactions.

Takeaway Notes:
The lecture provides practical examples on improvements of calculation of drug-target interactions with the help of open source program packages such as AutoDock, GROMACS, and MobyWat. Such information will help the members of the audience in future drug design projects and improve the efficiency of their job. The message of the lecture will also help teaching of up-to-date solutions of drug design problems.
