DescriptionWe employ spectroscopic, photophysical and computational tools to monitor molecular structure and behavior. We are interested in proteins and their interaction with drug candidates. Designing and testing mechanistic models for enzyme activity and inhibition by candidate drugs is our final goal. We are also interested in the linear and non-linear electronic spectra and photophysics of chromophoric compounds that show a potential for photonic applications. Steady-state spectroscopic properties are investigated by UV-vis, CD and fluorescence spectroscopies, including linear polarization and anisotropy measurements. Sub-ns time-resolved fluorescence decay measurements provide additional information on fluorophores, including single tyrosines and tryptophans in proteins. State-of-the-art computational tools, including those based on TDDFT theory and on multi-reference multi-state approaches, are used to analyze the excited electronic states of relevant chromophores. We mainly work in vitro. However, we develop fluorescence-based assays for confocal microscopic monitoring of localization, interaction and inhibition of target enzymes within cells.
