Biochem/physiol Actions

MitoPQ (MitoParaquat) is a mitochondria-targeted redox cycler composed of the lipophilic triphenylphosphonium (TP) cation-conjugated paraquat that induces mitochondria superoxide production via redox cycling at the complex I flavin site. MitoPQ increases mitochondria superoxide production at a ~1000-fold higher efficacy than untargeted paraquat using either live cells (fold of change of MitoSox fluorescence = 1.4/1 μM & 3.2/5 μM MitoPQ vs 1.2/5 mM PQ; C2C12 myoblasts) or isolated mitochondria (fold of increase of H2O2 efllux = 4.6/1 μM MitoPQ vs 2.6/1 mM PQ; rat heart mitochondria).
