A new method for the preparation of S-trityl(i.e. triphenylmethyl) and S-diphenylmethyl-cysteines or -cysteine peptides involves treatment of cysteine or cysteine peptides with aralkylcarbinols in the presence of trifluoroacetic acid or hydrogen halides in acetic acid solution. The optimal conditions for the removal of these S-protecting aralkyl groups by trifluoroacetic acid or hydrogen halide...
متن کاملS-Alkylcysteinase: Enzymatic Cleavage of S-Methyl-L-cysteine and Its Sulfoxide*
S-Methylcysteine has been isolated from the nonprotein nitrogen fractions of cabbage, turnips, and several other crucifers, and the structure of the amino acid was established by chemical studies and by comparison with a synthetic material (14). Subsequently, this compound has been found in garlic and onion (5)) kidney bean seeds (6)) Neurospora crassa (7)) and the hemolymph of Prod&a ericlenia...
متن کاملMethionine sulfoxide reductase A and a dietary supplement S-methyl-L-cysteine prevent Parkinson's-like symptoms.
Parkinson's disease (PD), a common neurodegenerative disease, is caused by loss of dopaminergic neurons in the substantia nigra. Although the underlying cause of the neuronal loss is unknown, oxidative stress is thought to play a major role in the pathogenesis of PD. The amino acid methionine is readily oxidized to methionine sulfoxide, and its reduction is catalyzed by a family of enzymes call...
متن کاملPost-Intake of S-Ethyl Cysteine and S-Methyl Cysteine Improved LPS-Induced Acute Lung Injury in Mice
The effects of S-ethyl cysteine (SEC) and S-methyl cysteine (SMC) on lipopolysaccharide (LPS)-induced acute lung injury in mice were examined. Eight hours after LPS challenge, SEC or SMC was supplied in drinking water at 0.5% or 1% for 3 days. LPS increased lung myeloperoxidase activity, neutrophil counts and edema. SEC or SMC post-intake attenuated these events. SEC or SMC suppressed LPS-induc...
