2-Phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-Oxide (PTIO?) Radical Scavenging: A New and Simple Antioxidant Assay in Vitro

Current in vitro antioxidant assays have several limitations, which frequently cause inconsistent results. The study develops a new antioxidant assay using the 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide radical (PTIO?). After the in

The Oxidative Properties of Nitroxy-radicals in Their Reactions with Sterically Hindered Hydroxylamines

A relative scale of the oxidative properties of cyclic nitroxy-radicals has been constructed and the influence of various structural factors on the oxidising capacity of the nitroxy-group in the radicals has been investigated.It is shown that the oxidative properties of the nitroxy-group in cyclic nitroxy-radicals become more pronounced with the increase in ring size.A relation has been established between the oxidative properties and the electron-accepting properties of functional groups separated from the nitroxy-group by two and more ?-bonds.
