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 کاملBlood dyscrasia in calves induced by S-(dichlorovinyl)-L-cysteine.
I N THEIR SEARCH for the toxic factor in trichloroethylene-extracted soybean oil meal which can induce fatal aplastic anemia in calves,”2 cattle,3 and horses,4 McKinney et al.5 synthesized S-( dichlorovinyl)-L-cysteine (DCVC). They reported that the oral administration of this compound to calves produced leukopenia, thrombocytopenia, a relative lymphocytosis and a hemorrhagic syndrome, conditio...

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 کاملPotent and selective inhibition of human nitric oxide synthases. Selective inhibition of neuronal nitric oxide synthase by S-methyl-L-thiocitrulline and S-ethyl-L-thiocitrulline.
Potent and selective inhibition of neuronal nitric oxide synthase (nNOS) compared to endothelial NOS (eNOS) and inducible NOS (iNOS) may be useful to treat cerebral ischemia (stroke) and other neurodegenerative diseases. S-Methyl-L-thiocitrulline (Me-TC) and S-ethyl-L-thiocitrulline (Et-TC) inhibited the oxidation of L-arginine and the L-arginine-independent oxidation of NADPH by nNOS from huma...
