Main research topics

Studies are based on QSAR (quantitative structure-activity relationships) and molecular modeling approaches for characterizing the relationship between the structure of chemical compounds and their biological effect. The models use integral and local two-dimensional (2D) and / or three-dimensional (3D) structural features; the effect may be medicinal (therapeutic), toxic etc.

Depending on the information available on the 3D structure of the target biomacromolecule, ligand-based and structure-based approaches are used including: pharmacophore modeling, molecular fields analysis, homology modeling of proteins, docking and virtual screening of bioactive compounds, identification and analysis of protein-lignad interactions, formation of chemical categories using different chemometrical methods. The applications are in the field of rational drug design and evaluation of toxic effects of chemicals on human health and environment. Subject matter is highly interdisciplinary and integrates knowledge from scientific fields such as medicine, pharmacology, physics, chemistry, methods of structural analysis, mathematical and engineering methods (mathematical statistics, pattern recognition, experimental design, programming, software development etc.
