Procysteine

Procysteine is a prodrug form of cysteine that is metabolized to cysteine intracellularly and has antioxidant activity. It reduces TNF-alpha-induced increases in the expression of IL-6 and chemokine (C-C motif) ligand 2 (CCL2) in ARPE-19 human retinal pigment epithelial cells when used at a concentration of 0.5 mM. Procysteine (6.5 mmol/kg) also increases liver glutathione (GSH) levels in fasted, but not fed, mice. It reduces the production of reactive oxygen species (ROS) in bronchoalveolar lavage fluid (BALF) and decreases plasma extravasation in the lungs, as well as reverses decreases in the levels of hypoxia-inducible factor (HIF-1alpha) in a mouse model of allergic asthma when administered at doses of 80 and 160 mg/kg.Formal Name: 2-oxo-(4R)-4-thiazolidinecarboxylic acid.
