Inhibition of glycation is an important approach for alleviating diabetic complications. Alliin, the most abundant sulphur compound in garlic has been demonstrated to possess antidiabetic activity. However, there is no scientific evidence supporting its antiglycating activity. The objective of this study was to determine the inhibitory effect of alliin on glucose and methyglyoxal (MG)-induced glycation of an important antioxidant enzyme, superoxide dismutase (SOD). Glycation of SOD resulted in a decrease in enzyme activity, fragmentation/cross-linking, reduced cross-reactivity with anti-SOD antibodies, both tertiary and secondary structural changes, and formation of AGEs and fibrils. Alliin offered protection against glucose or MG induced glycation of SOD. The antiglycating potential of alliin appears to be comparable with that of quercetin which is reported to be a potent natural inhibitor of glycation. Alliin has a good antiglycating effect and hence is expected to have therapeutic potential in the prevention of glycation-mediated diabetic complications.
