520 | 3 | _aSpectroscopy is an important tool for detecting drug binding to amino acid sequences. One such important spectroscopic process is the fluorescence quenching due to charge transfer (CT) processes between a drug molecule and the chromophore center of Human Serum Albumin (HSA). We present a theoretical investigation of the CT occurring upon electronic excitation when a dimetridazole (Dmz) molecule incorporated in HSA interacts with tryptophan residue (Trp214). Structures of the donor–acceptor complexes were optimized using density-functional theory in vacuum as well as extracted from molecular dynamics (MD) trajectories of the Dmz and Trp214 complexes in HSA (Dmz&Trp214@HSA). Absorption, emission, and fluorescence quenching of the Trp214&Dmz complex in a large number of MD conformers were calculated using various quantum-mechanical approaches in order to generate statistical spectra that are then used for studying the CT between the non-bonded donor and the acceptor. | |
