Interaction of coumarin triazole analogs to serum albumins : Spectroscopic analysis and molecular docking studies
© 2020 John Wiley & Sons Ltd..
The interaction of triazole substituted 4-methyl-7-hydroxycoumarin derivatives (CUM1-4) with serum albumin (bovine serum albumin [BSA] and human serum albumin [HSA]) have been studied employing ultraviolet-visible (UV-Vis), fluorescence, circular dichroism (CD) spectroscopy, and molecular docking methods at physiological pH 7.4. The fluorescence quenching occurred with increasing concentration of CUMs, and the binding constant of CUM derivatives with BSA and HSA obtained from fluorescence quenching experiment was found to be ~ 104 L mol-1 . CD study showed conformational changes in the secondary structure of serum albumin upon titration of CUMs. The observed experimental results were further validated by theoretical studies involving density functional theory (DFT) and molecular docking.
