Nitrones: not only extraordinary spin traps, but also good nitric oxide sources in vivo
Acta Pharmaceutica, 2015 Free radicals are involved in the development of reperfusion injuries. Using a spin trap, the intensity of such lesions can be reduced. Nitrones (effective in vivo spin traps) were tried in this work as in vivo nitric oxide donors.
