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

4,5-Dihydro-1H-imidazole 3-oxides bearing different substituents at positions 1 and 2 of the heterocycle were shown to react with a wide range of acceptor-substituted alkynes forming corresponding cycloadducts - derivatives of 1,2,3,7a-tetrahydroimidazo[1

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.
