| Hazard Information | Back Directory | [Description]
Mito-TEMPO (1334850-99-5) is a mitochondria-targeted antioxidant. Partially prevents mitochondrial permeability transition pore opening, necrosis and mitochondrial apoptosis after ATP depletion recovery.1?Resolves mitochondrial oxidative stress and rescues coronary collateral growth in Zucker obese fatty rats.2?Protects mitochondrial membrane potential and attenuates reperfusion-induced ROS production in a mouse ventricular myocyte model.3?Abrogates the induction of senescence in a human vascular smooth muscle cell model.4 | [Uses]
MitoTEMPO has been used as a mitochondria-targeted antioxidant. | [Biochem/physiol Actions]
MitoTEMPO is a mitochondrially targeted antioxidant, a specific scavenger of mitochondrial superoxide. MitoTEMPO is a combination of the antioxidant piperidine nitroxide TEMPO with the lipophilic cation triphenylphosphonium, giving MitoTEMPO the ability to pass through lipid bilayers with ease and accumulate several hundred-fold in mitochondria. Mitochondrial dysfunction and oxidative stress contribute to a variety of disorders involving cardiovascular, kidney, liver disorders, Parkinson′s and Alzheimer′s disease. | [References]
