In the present study, the mutual interaction of metformin hydrochloride (MET) with bovine serum albumin (BSA) was investigated using fluorescence spectroscopy under different conditions. It was observed that the fluorescence  quenching of BSA by metformin hydrochloride is a result of the formation of metformin hydrochloride- BSA complex with probable involvement of tryptophan residue. Fluorescence quenching constants were determined using  the Stern- Volmer equation and Van’t Hoff equation to provide a measure of the thermodynamic parameters ?<em>G</em>, ?<em>H</em>, and ?<em>S </em>at different temperatures indicating that the hydrogen bond and the hydrophobic forces play a major role for metformin hydrochloride- BSA association.</p> <p>DOI: <a href="http://dx.doi.org/10.3329/dujps.v11i1.12486">http://dx.doi.org/10.3329/dujps.v11i1.12486</a></p> <p>Dhaka Univ.
