Paper Abstract
We report here on a recent time-resolved fluorescence study [1] of the interaction between flurbiprofen (FBP), a chiral
non-steroidal anti-inflammatory drug, and human serum albumin (HSA), the main transport protein in the human body.
We compare the results obtained for the drug-protein complex with those of various covalently linked flurbiprofentryptophan
dyads having well-defined geometries. In all cases stereoselective dynamic fluorescence quenching is
observed, varying greatly from one system to another. In addition, the fluorescence anisotropy decays also display a clear
stereoselectivity. For the drug-protein complexes, this can be interpreted in terms of the protein microenvironment
playing a significant role in the conformational relaxation of FBP, which is more restricted in the case of the (R)-
enantiomer.
