Description

Application

2-phenyl-4, 4, 5, 5,-tetramethylimidazoline-1-oxyl 3-oxide (PTIO) has been used as a nitric oxide (NO) scavenger.

Biochem/physiol Actions

2-phenyl-4, 4, 5, 5,-tetramethylimidazoline-1-oxyl 3-oxide (PTIOs) derivatives react with nitric oxide (NO) to yield the corresponding imino nitroxides (PTIs) and nitrogen dioxide (NO2).

A stable radical scavenger for nitric oxide; affects NO without affecting NO synthase; has significant inhibitory activity against NO biological actions.
