CAS:2-Mercapto-L-histidine is a dietary amino acid that has been shown to be an effective inhibitor of opportunistic fungal growth in vitro. It has been shown to have a second-order rate constant of 0.0037 s−1, which is the same as lysine and arginine. This compound also inhibits the growth of fungi by competing with tryptophan for binding sites on the enzyme histidine ammonia-lyase. 2-Mercapto-L-histidine can also react with nucleophiles such as divalent cations and form covalent bonds, which may lead to its antimicrobial activity against Gram-positive bacteria. 2-Mercapto-L-histidine is not active against Gram negative bacteria or yeast due to structural differences in their cell walls. 2-Mercapto-L-histidine has been shown to inhibit glucose metabolism and plasma glucose levels in vitro, but it does not affect insulin secretion orFormel:C6H9N3O2SReinheit:Min. 95%Farbe und Form:PowderMolekulargewicht:187.22 g/mol2-Mercapto-L-histidine
CAS:Kontrolliertes ProduktApplications An intermediate in the formation of L-egothioneine, a natural amino acid ubiquitously present in cells and tissues of most plants and mammalian species. In humans, L-ergothioneine is found in red blood cells, liver, kidney, brain, seminal fluid, and cataract-free lenses at concentrations ranging from 100 uM to 2 mM. L-ergothioneine is exclusively biosynthesized in fungi and mycobacteria. Hence, humans assimilate it through dietary intake.L-ergothioneine has been proven to act as an antioxidant in vivo and to afford protection from g and UV radiation as well as from singlet oxygen in vivo. Recently, it has been shown that L-ergothioneine protects isolated perfused heart against the deleterious effect of post-ischemic reperfusion.The intermediate, 2-mercaptohistine has been used for the
