AGE modification of proteins and thereby damages to cells and tissues have been confirmed to contribute to the pathophysiology of aging and long-term complications of various age-related diseases. Anti-AGEs therapy has thus received significant attention, and several flavonoids including quercetin (1) and (−)-epigallocatechin gallate (EGCG) (2) have shown anti-AGEs activity through trapping and inactivating methylglyoxal (MGO), the crucial intermediate of AGEs formation. However, in the field of MGO-scavenging activity, (−)-epigallocatechin (EGC) (3), one of the key flavonoids in green tea, has received less attention compared with other flavonoids. In this study, we have shown strong MGO-scavenging activity of EGC (3), and EGC (3) was found to be equipotent to previously identified MGO-scavengers such as quercetin (1) and EGCG (2).
