The aim of the present study was investigate the interaction between bovine serum albumin and triamcinolone. For this purpose, the interaction between BSA and triamcinolone was evaluated by UV–Vis and fluorescence spectroscopy under different temperatures, and different salt concentration at physiological pH (7.4). The binding constant of BSA-Triamcinolone system were evaluated different temperature at constant (pH =7.4) and ionic strength (0.01 M). The binding constant dependence of binding constant on temperature was analysed by Van’t Hoff equation. The standard enthalpy change (DeltaH) and standard entropy change (DeltaS) values were determinated respectively as 9.0 kcal/mol while as 54.1 cal/mol.K.. In addition, the effect of salt concentration investigated for BSA-Triamcinolone system at constant temperature (T=25°C) and increasing salt concentration lead to decrement on the binding constant value. The obtained thermodynamic parameters indicate hydrophobic forces take major role in BSA-Triamcinolone interaction. The arousal of salt concentration prompted to diminution on affinity between Triamcinolone and BSA.
