摘要
Mito-DEPMPO, a new DEPMPO analogue bearing a triphenylphosphonium group, was synthesized via a novel NH2-reactive DEPMPO. The half-life of the Mito-DEPMPO superoxide adduct was estimated to be ca. 40 min. Using Mito-DEPMPO, reactive oxygen species generated in intact mitochondria were detected and characterized by EPR.
