Cancer chemoprevention by the antioxidant tempol acts partially via the p53 tumor suppressor.
Hum Mol Genet. 2005 Jun 15;14(12):1699-708. Epub 2005 May 11. Erker L¹, Schubert R, Yakushiji H, Barlow C, Larson D, Mitchell JB, Wynshaw-Boris A. ¹Department of Pediatrics, UCSD School of Medicine, La Jolla, CA Abstract We previously demonstrated that the nitroxide antioxidant tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl) increased latency to tumorigenesis and doubled (100%) the lifespan of Atm-deficient […]

Nitroxide stable radical suppresses autoimmune uveitis in rats.
Free Radic Biol Med. 1999 Jul;27(1-2):7-15. Zamir E¹, Zhang R, Samuni A, Kogan M, Pe’er J. ¹Department of Ophthalmology, Hadassah-Hebrew University Medical School, Jerusalem, Israel. Abstract Free radicals have been implicated in the pathogenesis of experimental autoimmune uveoretinitis (EAU). Nitroxides are stable radicals with a superoxide-dismutase-mimicking activity, which exert an anti-inflammatory effect in various animal […]

Tempol produced regression of Crohn’s Disease
Oxidative stress plays a significant role in the pathogenesis of inflammatory bowel disease. Endogenous antioxidants such as superoxide dismutase (SOD), glutathione, and catalase are normally able to counteract oxidative stress in the intestinal mucosa. However, inflammation increases the demand for these important antioxidants and results in an imbalance between pro-oxidants and antioxidants, with subsequent mucosal […]
