MedKoo CAT#: 317102

CAS#: 845959-50-4 (mesylate)

Description: Mitoquinone mesylate, also known as MitoQ or MitoQ10; is a mitochondria-targeted antioxidant designed to accumulate within mitochondria in vivo in order to protect against oxidative damage. MitoQ comprises a positively charged lipophilic cation that drives its extensive accumulation within the negatively charged mitochondria inside cells. The active antioxidant component of MitoQ is ubiquinone, which is identical to the active antioxidant in Coenzyme Q10. It is this approximately thousand-fold greater concentration of MitoQ within mitochondria that makes it more effective at preventing mitochondrial oxidative damage when compared to untargeted antioxidants such as Coenzyme Q10. NOTE: For the convenience of use, this product is supplied as 200mg /mL solution in ethanol-water (1:1, v/v) solution since pure MitoQ10 is a tar-like or waxy semi-solid and very hard to transfer between containers.

Additional Information

MitoQ is the first molecule specifically designed to decrease mitochondrial oxidative damage to have undergone clinical trials in humans.

MitoQ was designed in the late 1990s as a mitochondria-targeted antioxidant by Michael P. Murphy and Robin A. J. Smith. At the time, both were at the University of Otago, Dunedin, New Zealand where Murphy was a mitochondrial biochemist in the Department of Biochemistry and Smith was an organic chemist at the Department of Chemistry. The molecule was made by a PhD student in Smith’s lab, Geoffrey Kelso, and the first publication on MitoQ was in 2001. Since then over 180 publications on MitoQ have been recorded. MitoQ is the first physiologically active form of CoQ10 specifically targeted to mitochondria in order to decrease oxidative damage to have undergone clinical trials in human patients.

MitoQ was designed to accumulate extensively within mitochondria in vivo in order to increase the local antioxidant capacity and thereby decrease mitochondrial oxidative damage. To do this MitoQ incorporates a lipophilic cation, that is a positively charged component that is sufficiently hydrophobic, or “oily”, to be able to pass directly through biological membranes. The lipophilic cation used is based on the triphenylphosphonium structure, which is well known to accumulate within the negative mitochondrial matrix. In the solid form of MitoQ the positive charge is neutralised with a negatively charged anion, typically mesylate, to form a salt. MitoQ is present in two different forms, the oxidised ubiquinone form, MitoQuinone and the reduced ubiquinol form, MitoQuinol. MitoQ can refer to either form or to a mixture of the forms.

One on the Phase II clinical trials was on Parkinson's disease where patients were given an oral MitoQ dose of 40 or 80 mg per day for a year and compared with placebo. This trial was registered on clinicaltrials.gov as NCT00329056.

The Parkinson’s Disease trial did not show a benefit of MitoQ, probably because the irreversible neuronal damage was too great by the time the patients were diagnosed; however, this study did provide a year’s safety data. In the other trial patients with hepatitis C virus who were not responding to antiviral treatments were assessed for prevention of liver inflammation. This trial was registered on clinicaltrials.gov as NCT00433108. The trial in hepatitis C virus patients did show liver protection. These two trials showed that it was safe to target mitochondria in humans long term and other trials for MitoQ are now planned.

The development of MitoQ has led to two further developments. One was a skin cream incorporating MitoQ which is used to combat the signs of skin ageing (mitoq.com). The other was an oral supplement containing a low dose of MitoQ which can be used as a nutritional supplement. (from https://en.wikipedia.org/wiki/MitoQ).
