here we report at a 2-mm concentration , the monoethyl and monomethyl esters of gsh , n-acetyl-l-cysteine , and l-2-oxothiazolidine-4-carboxylate are all significantly more effective than gsh in inhibiting the sharp decline in the intracellular ratio of reduced gsh/oxidized glutathione ( gssg ) , the prolonged decrease in gsh peroxidase ( gsh : h2o2 oxidoreductase , ec 1.11.1.9 ) activity , and the induction of odc activity caused by 1 microm tpa .
