General description
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 efflux = 4.6/1 μM MitoPQ vs 2.6/1 mM PQ; rat heart mitochondria). MitoPQ is a valuable tool for conducting cellular and in vivo investigations into the role of mitochondrial superoxide generation in redox biology. Additionally, it can be utilized as a catalyst or co-stressor to replicate metabolic and neurodegenerative disease traits in experimental models.
Application
MitoPQ has been used to enhance mitochondrial reactive oxygen species (mitoROS) production in T-cell culture and investigate its influence over T-cell differentiation.
