Insight into the mechanistic binding of bovine serum albumin (BSA) with doxofylline can layout pivotal enlightenment with relevance to pharmacokinetics and pharmacodynamics properties. Herein, many spectroscopic techniques and computational methods had been employed to interpret the structural and binding dynamics of BSA-doxofylline interaction. Doxofylline quenched the intrinsic fluorescence of BSA by static quenching. The stoichiometry and the binding constant of the BSA-doxofylline complex were 1:1 and in the order of 10³ M⁻¹. It was also concluded that the binding process was spontaneous and exothermic, primarily based on the thermodynamic study. Circular dichroism and three-dimensional excitation-emission matrix fluorescence results concluded pronounced conformational and microenvironmental changes in BSA structure on binding with doxofylline. The influence of metal ions and vitamins on the binding affinity of the BSA-doxofylline system were also explored. The in vitro findings were further supported by in silico analysis. With a score value of −6.25 kcal/mol, molecular docking showed strong interactions. Molecular dynamics simulation interpretation also suggested the stable binding with lower deviation in the values of RMSD and RMSF obtained by uninterrupted long simulation run. These studies will propose the optimum potency of distribution of the doxofylline into the bloodstream for asthma treatment.
