mitop

MitoP is a phenol product produced by the reaction of H2O2 with the ratiometric mass spectrometry probe MitoB . MitoB contains a triphenylphosphonium cation component that drives its accumulation in mitochondria where its arylboronic moiety selectively reacts with H2O2 to produce MitoP. Quantifying the MitoP/MitoB ratio by LC-MS/MS reflects the mitochondrial matrix H2O2 concentration.

MitoPQ (MitoParaquat) is a mitochondria-targeted small molecule compound that selectively enhances mitochondrial superoxide and hydrogen peroxide levels and inhibits insulin-stimulated glucose uptake and translocation of glucose transport protein 4 (GLUT4) to the plasma membrane in adipocytes and myotubes.MitoPQ can be used to MitoPQ can be used to study mitochondrial oxidative stress and regulated GLUT4 transporter.

Mitopodozide, as an ethylhydrazide derivative of podophyllic acid, acts as a mitotic poison in carcinomas of the ovary.

a fluorescent probe for imaging hydrogen peroxide (H2O2) in mitochondria of living cells

MitoPBN is a mitochondria-targeted antioxidant that accumulates in the mitochondria following the generation of a mitochondrial membrane potential by succinate, an effect blocked by the addition of the mitochondrial membrane potential uncoupler FCCP. MitoPBN inhibits superoxide activation of mitochondrial uncoupling protein 1 (UCP1), UCP2, and UCP3 at a concentration of 250 nM in vitro, but does not react with superoxide. It traps hydroxyl (IC50 = ~77 μM) and carbon-centered radicals and inhibits the initiation of lipid peroxidation in isolated bovine heart mitochondria.

P62-mediated mitophagy inducer (PMI) is a regulator of mitophagy.
