Description

General description

6-Hydroxymelatonin (6-OHM) is a melatonin metabolite. It is produced in the liver by the action of cytochrome P450 enzyme as well as by photodegradation of melatonin. In the central nervous system, it exists as a sulfated form. 6-OHM is a partial melatonin receptor MT2 agonist.

Application

6-Hydroxymelatonin has been used as a melatonin derivative to test its protective effects in ultra violet B (UVB)-induced oxidative stress melanocytes and keratinocytes.

Biochem/physiol Actions

6-Hydroxymelatonin (6-OHM) is an antioxidant with a free radical scavenging role. Like melatonin, it reduces the impact of UVB-induced oxidative stress in melanocytes. It also aids protection during iron (Fe²⁺)-induced neurotoxicity. 6-OHM effectively reduces lipid peroxidation and superoxide anion production induced by potassium cyanide (KCN).
