Disease relevance of NSC342431

• Furthermore, the effects of antioxidants (superoxide dismutase (SOD); catalase and 2-oxothiazolidine-4-carboxylic acid (OTZ) and buthionine sulfoximine (BSO) were added to search for the possible mechanism of action, as well as a method for the prevention, of cigarette smoking-associated periodontal diseases [1].

High impact information on NSC342431

• However, when incubated with L-cysteine, radioactivity incorporation in the acid-soluble fraction was almost doubled, and about one-third of the radioactivity of this fraction was identified as 2-oxothiazolidine 4-carboxylic acid [2].
• In contrast, generation of cysteine from 2-oxothiazolidine-4-carboxylate by the reaction of 5-oxoprolinase or from methionine by the transsulfuration pathway appears not to take place in these cultured neurons [3].
• The radiation responses at various oxygen tensions were evaluated in V79 Chinese hamster cells under conditions where their nonprotein thiols, primarily glutathione (GSH), were elevated by 2-oxothiazolidine-4-carboxylate (OTZ) [4].
• In contrast, treatment with 2-oxothiazolidine-4-carboxylic acid (OTZ, a precursor of cysteine) increased GSH levels 1.7 fold compared with that of untreated cells, inhibited cell death induced by CDDP and switched the mode of cell death from necrosis to apoptosis (n/a<0.8, similar to untreated cells) [5].
• Furthermore, to determine whether oxidative stress could modulate HO-1 expression in HGFs by root canal sealers, HGFs were pretreated with glutathione (GSH) synthesis precursor 2-oxothiazolidine-4-carboxylic acid (OTZ) and GSH synthesis inhibitor buthionine sulfoximine (BSO) for 24 h [6].

Analytical, diagnostic and therapeutic context of NSC342431

• The effect of lactated Ringer's (LR) resuscitation with or without the addition of 2-oxothiazolidine-4-carboxylate (OTC), a cysteine prodrug (enhancing glutathione production) on liver injury, if any, were investigated [7].
