4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy Chemical Properties,Uses,Production

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.

Biological Activity

Superoxide scavenger that displays neuroprotective, anti-inflammatory and analgesic effects.
