Article abstract of DOI:10.1246/cl.1997.1059

New nitrones of 5,5-dimethyl-1-pyrroline N-oxide (DMPO)-type , 3-hydroxymethyl-5,5-dimethyl-1-pyrroline N-oxide (3HM-DMPO) and 3-(3-hydroxypropyl)-5,5-dimethyl-1-pyrroline N-oxide (3HP-DMPO), were synthesized and tested for the ability in radical trapping of oxygen-centered radicals. 3HM-DMPO trapped superoxide but did not hydroxyl radicals, whereas 3HP-DMPO served as a trap for both radicals.
