Reductic acid (2,3-dihydroxy-2-cyclopentenone, 1) decreased the ESR signal of 5,5-dimethyl-1-pyrroline 1-oxide (DMPO)-OH produced by hydroxyl radical and DMPO. 1 also inhibited lipid peroxidation initiated by cytochrome P450 and tertbutyl hydroperoxide. 1 inhibited xanthine oxidase activity, while ascorbic acid and 2-hydroxytetronic acid, an ascorbic acid analogue without side chain, did not.
