應用

3-Cyano-PROXYL is a stable free radical that can be used in the ESR technique as a nitroxide standard:
  • For the estimation of relative concentrations of the spin adducts of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) with ·OH and O2.- radicals.
  • For the determination of free radicals present in an aqueous cigarette tar extract.

The nitroxide Tempol, a stable free radical, has recently been shown to protect mammalian cells against several forms of oxidative stress including radiation-induced cytotoxicity. To extend this observation, six additional water-soluble nitroxides with different structural features were evaluated for potential
