| Summary, etc. | Objective:The aim of the present study was to investigate the mode and mechanism of interactions involved towards binding of valganciclovir (VGC) with Human Serum Albumin (HSA) by spectroscopic and molecular modeling studies which can be extrapolated for the ten folds increase of bioavailability over its prodrug galanciclovir. Methods: Herein we employed fluorescence spectroscopy for evaluating the binding constant value, site of interaction and changes in the microenvironment of HSA fluorophores. Circular dichroism (CD) and UV-Visible spectroscopy is used for conformational changes of HSA in the event of binding of valaganciclovir. These experimental studies were further corroborated with molecular modeling studies. Results: Considerable quenching of fluorescence intensities of fluorophores in the presence of VGC showed that VGC interacts with HSA strongly with a binding constant of 4.11x104 M-1Conclusion:The weaker dominant electrostatic interactions with minor contributions of hydrophobic interactions of VGC with HSA at site IB (catalytic domain) might be the probable reason for the relative increase of hydrolysis of VGC to galanciclovir. And moderate binding constant value with HSA implies that HSA can be able to transport VGC under physiological conditions. with a free energy change of-6.26 Kcal/mol. Synchronous fluorescence and CD studies show that the microenvironment and confirmation of HSA are slightly altered in the presence of VGC. Though site marker experiments does not give any clue for identification of site, molecular docking studies showed that VGC binds to site IB of HSA |
