5-(Diethoxyphosphoryl)-5-methyl-1-pyrroline N-oxide (DEPMPO, 2), a new spin trap, has been synthesized via a two-step synthetic route, and its ability to spin trap oxy radicals in biological milieu has been addressed. The in vitro spin trapping of hydroxyl and superoxide radicals was investigated in a phosphate buffer 0.1 M, and the hyperfine coupling constants of the spin adducts were determined. The rates of spin trapping of hydroxyl and superoxide radicals with 2 were found to be close to those reported for 5,5-dimethyl-1-pyrroline N-oxide (DMPO). However, the DEPMPO-superoxide spin adduct was shown to be significantly more persistent (15 times at pH 7) than the DMPO--superoxide spin adduct. Using 2 as a spin trap, the production of superoxide has been clearly characterized during the reperfusion of ischemic isolated rat hearts.
