Abstract

A selenium–quercetin complex (SEQC) was synthesized and its structure was identified by IR, LC-MS and 1H-NMR. Its biochemical effects on bovine serum albumin (BSA) were studied by measuring its molecular spectra including three-dimensional fluorescence, ultraviolet and circular dichroism (CD) spectra. The interaction of SEQC and BSA is discussed in terns of fluorescence quenching and Förster’s non-radiation energy transfer theory. The thermodynamic parameters \(\Delta H^{\uptheta}\), \(\Delta G^{\uptheta}\), and \(\Delta S^{\uptheta}\) were calculated at different temperatures and the results indicate that the interaction is an endothermic as well as an entropy generating process. The binding site was explored by the fluorescence probe technique using warfarin and ibuprofen as markers. It was found that around body temperature hydrophobic forces maintained the average distance from the tryptophan residue in domain II of BSA (donor) to SEQC (acceptor) at 3.76 nm. The conformational changes of BSA were investigated by three-dimensional fluorescence and circular dichroism spectra.
