This study demonstrates the antiglycation activity of Nordihydroguaiaretic acid, a lignin from the creosote bush (Larrea tridentate), which has also been proven to assist in the treatment of cancer, neurological disorders, and cardiovascular complications. We determined the antiglycation activity of NDG based on spectroscopic analysis, molecular interactions and circular dichroism studies with albumin. It was also seen that NDG inhibits the aggregation of albumin, after glycation, using Thioflavin T binding and confocal imaging. Results suggest that NDG is a potent inhibitor of advanced glycation end products formation. NDG was found to impart protective effects on albumin by preventing glycation modification of lysine residues (Lys20, Phe36, Lys41, Lys131, and Lys132) due to glycation.
