L-Ergothioneine is a stable antioxidant that can be found under conditions of excessive oxidative stress in plant and animal tissue. L-ergothioneine has the ability to scavenge free radicals and protect cells from UV-induced ROS with higher efficiency than antioxidants coenzyme Q(10) or idebenone, thus making it more effective antioxidant. The compound has been shown to be a non-toxic thiol buffering antioxidant, enhance cell viability induced by hydrogen peroxide (H2O2), and inhibit DNA oxidation by peroxynitrite (ONOO-) in the human neuronal hybridoma cell line (N-18-RE-105).
L-(+)-Ergothioneine is a naturally-occurring amino acid derived from histidine via hercynine.1 Ergothioneine is a stable antioxidant that scavenges and detoxifies free radicals and oxidants, increases intracellular thiol levels, controls nuclear factor-κB activation, and inhibits inflammatory gene expression.In addition, it inhibits the peroxynitrite-dependent nitration of nitrotyrosine, blocks oxidative DNA damage and cell death, and prevents the formation of xanthine and hypoxanthine. Ergothioneine is transported by the organic cation/carnitine transporter, which has been linked with autoimmune diseases, including rheumatoid arthritis and Crohn’s disease.
