Adrenochrome


Adrenochrome is a chemical compound with the molecular formula C9H9NO3 produced by the oxidation of adrenaline. The derivative carbazochrome is a hemostatic medication. Despite a similarity in chemical names, it is unrelated to chrome or chromium.

Chemistry

In vivo, adrenochrome is synthesized by the oxidation of epinephrine. In vitro, silver oxide is used as an oxidizing agent. In solution, adenochrome is pink and further oxidation of the compound causes it to polymerize into brown or black melanin compounds.

Effect on the brain

Several small-scale studies conducted in the 1950s and 1960s reported that adrenochrome triggered psychotic reactions such as thought disorder and derealization. Researchers Abram Hoffer and Humphry Osmond claimed that adrenochrome is a neurotoxic, psychotomimetic substance and may play a role in schizophrenia and other mental illnesses. In what they called the "adrenochrome hypothesis", they speculated that megadoses of vitamin C and niacin could cure schizophrenia by reducing brain adrenochrome. The treatment of schizophrenia with such potent anti-oxidants is highly contested. In 1973, the American Psychiatric Association reported methodological flaws in Hoffer's work on niacin as a schizophrenia treatment and referred to follow-up studies that did not confirm any benefits of the treatment. Multiple additional studies in the United States, Canada, and Australia similarly failed to find benefits of megavitamin therapy to treat schizophrenia.
The adrenochrome theory of schizophrenia waned, despite some evidence that it may be psychotomimetic, as adrenochrome was not detectable in people with schizophrenia. In the early 2000s, interest was renewed by the discovery that adrenochrome may be produced normally as an intermediate in the formation of neuromelanin. This finding may be significant because adrenochrome is detoxified at least partially by glutathione-S-transferase. Some studies have found genetic defects in the gene for this enzyme.

Legal status

Adrenochrome is unscheduled by the Controlled Substances Act in the United States. It is not an approved drug product by the Food and Drug Administration, and if produced as a dietary supplement it must comply with good manufacturing practice.
