Biochanin obstructs human serum albumin from non-enzymatic glycation: an in vitro approach

Abstract

Various serum proteins, like Human Serum Albumin (HSA) and others, are susceptible to glycation and the formation of Advanced Glycation End Products (AGEs). Diabetes and other diseases are associated with AGE development. Recently, isoflavones have been studied for their therapeutic benefits. In the present study, we glycated HSA with Methylglyoxal (MGO) with and without the test compound, i.e., Biochanin A (BCA), to test its antiglycating capacity. We studied the biochemical and biophysical effects of glycation on HSA with and without BCA and also took the help of the in silico technique. Analytical methods included intrinsic and extrinsic fluorescence, polyacrylamide gel electrophoresis (PAGE), UV spectroscopy, far UV circular dichroism, and others. For structural comprehension, TEM and SEM were used. Molecular docking and simulation were employed to observe BCA-HSA's site-specific interaction. Since HSA is a therapeutically relevant protein involved in many disorders, this study’s findings are important. Communicated by Ramaswamy H. Sarma
