Abstract:
The accurate prediction of the strength of protein–ligand interactions is a very difficult problem despite impressive advances in the field of biomolecular modeling. There are good reasons to believe that quantum mechanical methods can help with this task, but the application of such methods in the context of scoring is still in its infancy. Here we benchmark several wave function theory (WFT), density functional theory (DFT) and semiempirical quantum mechanical (SQM) approaches against high-level theoretical references for realistic test cases. Based on our findings for systematically generated model systems of real protein/ligand complexes from the PDB-bind database, we can recommend SCS-MP2 and B2-PLYP-D3 as reference methods, TPSS-D3+Dabc/def-TZVPP as the best DFT approach and PM6-DH+ as a fast and accurate alternative to full ab initio treatments.

Abstract:
Optimization of Semiempirical Quantum Mechanical Methods for in Silico Drug Design Doctoral thesis Kristian Kříž The subject of this thesis is the optimization of semiempirical quantum mechanical methods (SQM) for their use in in silico drug design. The thesis covers two topics - COSMO2 solvation model optimization part and PLF547, PLA15 dataset development part. The first part is devoted to the optimization of COSMO solvation model by addition of a nonpolar term and reparametrization of the model for SQM methods PM6 and PM7. We have shown that the accuracy of the resulting "COSMO2" optimized model improved on all the tested datasets and we have compared it to other selected SQM solvation models. The method has also been tested on the protein ligand complexes as a part of a scoring function, where it provides better preditction of binding affinity of drug candidates for their target protein. The second part of the thesis describes the construction of datasets for noncovalent interactions aimed speicificly to represent an environment of an enyzme active site complexed with a ligand with reliable benchmark values of interaction energies in vacuum and solvent (water). The developed PLF547 and PLA15 datasets are suitable for testing and development of methods for the use in drug design. We have...
