Ergothioneine
Ergothioneine is a naturally occurring metabolite of histidine that has antioxidant properties. -- Pubchem. Ergothioneine is a product of plant origin that accumulates in animal tissues. Ergothioneine is biosynthesized exclusively by fungi and mycobacteria and is captured by plants through their roots. As an ingredient of human food, ET is distributed very unevenly. By far, the highest levels of Ergothioneine have been found in mushrooms (0.1-1 mg/g dried material). Ergothioneine is rapidly cleared from the circulation and then avidly retained with minimal metabolism: the whole-body half-life of ingested Ergothioneine in rats is 1 month. The content of Ergothioneine varies greatly among tissues and is strongly dependent on its dietary level. In addition to erythrocytes and bone marrow, high Ergothioneine levels have also been found in seminal fluid. The precise physiological role of ET has remained elusive since its discovery in 1909. It is known that Ergothioneine is a powerful scavenger of hydroxyl radicals and an inhibitor of iron or copper ion-dependent generation of hydroxyl radicals from hydrogen peroxide (H2O2). A specific ergothioneine transporter has recently been identified (gene symbol SLC22A4 - PMID: 15795384). Ergothioneine appears to play a pivotal protective role in monocytes, because the occurrence of rheumatoid arthritis and Crohns disease has very recently been linked to variant ergothioneine transporter genes (PMID: 15795384). SLC22A4 is highly expressed in the kidney, where it is thought to aid in active secretion of organic cations, and may facilitate the active reabsorption of ergothioneine.

D020011 - Protective Agents > D000975 - Antioxidants Ergothioneine is an imidazole-2-thione derivative with orally active histidine betaine. Ergothioneine is a specific inhibitor of p38-MAPK and Akt, which plays a protective role in cell apoptosis induced by stress. Ergothioneine has antioxidant activity[1][2]. Ergothioneine, an imidazole-2-thione derivative of histidine betaine, is synthesized by certain bacteria and fungi. Ergothioneine is generally considered an antioxidant[1].
Orgothionenine
Orgothionenine belongs to histidine and derivatives class of compounds. Those are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Orgothionenine is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Orgothionenine can be found in oat, which makes orgothionenine a potential biomarker for the consumption of this food product.
Ergothioneine
A L-histidine derivative that is N(alpha),N(alpha),N(alpha)-trimethyl-L-histidine in which the hydrogen at position 2 on the imdazole ring is replaced by a mercapto group. A naturally occurring metabolite of histidine synthesized by bacteria and fungi with antioxidant properties. It is found ubiquitously in plants and animals and is present in many human foodstuffs.
