Short description of ongoing research projects

Our research is focused on NMR spectroscopy, NMR based Metabolomics Structure elucidation of biomolecules, natural products and drugs, as well as Structure Based Drug Design, Molecular Simulations, in silico screening and Structure Activity Relationships. Specific calculation protocols have been established and used in order to design new molecules with desired biological activity. Important experience has been gained through the systematic study of receptors like Kinases (CDKs, GSK3, DYRK, CK1), Nuclear Receptors (ERα, ERβ, AR), Epigenetic targets (bromodomains, UHRF) and membrane transporters. The group is also involved in several metabolomic projects covering areas like characterization of metabolic responses to chemical exposure (hepatotoxicity, cardiotoxicity), Functional genomics (NRF2) disease diagnosis (inborn error of metabolism, cancer), sports biochemistry and plant metabolic profiling.
