Biochem/physiol Actions

Adrenochrome is an oxidation product of adrenaline. It has been implicated in cardiotoxicity. It is a short-lived cytotoxic molecule and is part of the leukocyte response used to kill bacteria. Adrenochrome is also suggested to exhibit psychotomimetic effects. It is used to determine superoxide dismutase activity.

Complex I in bovine heart submitochondrial particles catalyses the NADH-supported generation of superoxide anion; adrenaline is oxidised by superoxide to adrenochrome that, on its hand, is reduced by Complex I, thus establishing a redox cycle that amplifies the superoxide production....
