Abstract

Hypocrellin A underwent one-electron reduction to form semiquinone radical anion in the presence of reducing biol. mols. such as methionine, uric acid, and reduced glutathione. The ESR signals of hypocrellin A semiquinone radical anion were observed in deaerated solution The superoxide anion radical was detected in aerated solution Singlet oxygen production was decreased and superoxide anion radical production was initiated in the presence of reducing agents.

Key words: METHIONINE, PARAMAGNETIC RESONANCE, FREE RADICAL, GLUTATHIONE, SENSITIZATION, URIC ACID, SEMIQUINONE, SINGLET OXYGEN, HYPOCRELLIN A
