TEMPOL is a cell-permeable spin label that has been used to quantify intracellular oxygen in various cell types by electron spin resonance (ESR) spectroscopy. Chemical Properties solid Uses A free radical scavenger Uses Spin label for EPR studies; phase transfer dehydration catalyst; antioxidant; inhibitor of olefin free radical polymerization. Uses Tempol, a water-soluble piperidine nitroxide derivative having nonspecific radical-scavenging and superoxide dismutase (SOD) activity, protects cultured aerobic, but not hypoxic, cells against radiation-induced killing. Protection does not depend on intracellular thiols and does not involve O2-depletion. Tempol reacts with peroxyl radicals and can also oxidize DNA-bound metal ions, thereby interfering with OH generation. Synthesis Reference(s) Synthetic Communications, 19, p. 3509, 1989 DOI: 10.1080/00397918908052760 General Description 4-Hydroxy-TEMPO is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative. It is a low-molecular weight compound and has been proposed as superoxide dismutase mimic.
