چکیده مقاله
In the present study the binding of diversin (DIV), a prenylated coumarin isolated from Ferula diversivittata, to bovine serum albumin (BSA) was investigated using surface plasmon resonance (SPR), spectrofluorimetry, and molecular docking approaches. Following the activation of carboxylic groups, via NHS/EDC, BSA was immobilized on the carboxymethyl dextran (CMD) hydrogel coated Au sensor, and was used for real-time monitoring of the interactions between DIV and BSA. KD value of DIV binding to BSA increased with increasing temperature, confirmed that the affinity between BSA and DIV decreases with rising temperature. In addition, the fluorescence and synchronous fluorescence spectroscopic data revealed that the intrinsic emission intensity of BSA was quenched via a dynamic mechanism. In addition, the micro-region around BSA tyrosine residue was changed upon interaction with DIV.
