Thiazolidine-4-carboxylic acid (TC) is a cyclic sulfur amino acid, a condensation product of cysteine and formaldehyde. The chemistry, biological effects and clinical use of TC are reviewed. Extensive animal experiments and studies on human subjects carried out in Europe indicate that a combination of TC and folic acid, 'Folcysteine', has revitalizing effects on age-related biochemical variables of blood and tissues. Further animal studies confirmed the anti-toxic effects of TC, particularly on the liver.

A series of 3-aryl amino/amino-4-aryl-5-imino-Delta(2)-1,2,4-thiadiazoline have been synthesized using an appropriate synthetic route and characterized by elemental analyses and spectral data. The anticonvulsant activity of all the synthesized compounds was evaluated against maximal electroshock induced seizures (MES) and subcutaneous pentylenetetrazole (ScPTZ) induced seizure models in mice. The neurotoxicity was assessed using the rotorod method.

Cell culture work suggests that signaling to polymerize cortical filamentous actin (F-actin) represents a required pathway for the optimal redistribution of the insulin-responsive glucose transporter, GLUT4, to the plasma membrane. Recent in vitro study further suggests that the actin-regulatory neural Wiskott-Aldrich syndrome protein (N-WASP) mediates the effect of insulin on the actin filament network. Here we tested whether similar cytoskeletal mechanics are essential for insulin-regulated glucose transport in isolated rat epitrochlearis skeletal muscle.

Oxidant-mediated injury plays an important role in the pathophysiology of inflammatory bowel disease (IBD). Recently, antioxidants were shown to modulate colitis in mice. In this study, the protective effects of L-cysteine and glutathione (GSH) prodrugs are further evaluated against progression of colitis in a murine model. ICR mice were fed compounds incorporated into chow as follows: Group (A) received chow supplemented with vehicle. Group (B) was provided 2-(RS)-n-propylthiazolidine-4(R)-carboxylic-acid (PTCA), a cysteine prodrug.
