Products Often Used Together with MitoQ (Mitoquinone) Mesylate

Visomitin (SKQ1)

It specifically targets the mitochondrial matrix and is highly effective at limiting reactive oxygen species (ROS) levels, along with Visomitin (SKQ1).

Trolox

It completely inhibits mitochondrial lipid peroxidation, whereas Trolox only partially inhibits mitochondrial lipid peroxidation in pretreated hepatocytes.

Mechanism of Action

Targets/IC₅₀/Ki	mitochondria ^[1] ROS ^[1]
In vitro	Mitoquinone blocks H2O2-induced intracellular ROS responses inmurine pancreatic acinar cells. Mitoquinone does not reduce mitochondrial depolarisation induced by either cholecystokinin (CCK) or bile acid TLCS. Mitoquinone increases basal and CCK-induced cell death in a plate-reader assay.^[1]
In vivo	In a TLCS-induced AP model Mitoquinone treatment is not protective. In AP induced by caerulein hyperstimulation (CER-AP), Mitoquinone exerts mixed effects. Thus, partial amelioration of histopathology scores is observed but without reduction of the biochemical markers pancreatic trypsin or serumamylase. Lungmyeloperoxidase and interleukin-6 are concurrently increased by Mitoquinone in CER-AP. Mitoquinone causes biphasic effects on ROS production in isolated polymorphonuclear leukocytes, inhibiting an acute increase but elevating later levels.^[1]
