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).

Night work is associated with disrupted circadian rhythms, fatigue, accidents, and chronic disease. Melatonin secretion helps regulate sleep and circadian rhythms. Melatonin, sleep disturbances, and symptoms (sleep, fatigue, mental) were compared among workers on permanent day, swing, and night shifts.

Melatonin, an indolic pineal hormone, is produced primarily at night in mammals and is important in controlling biological rhythms. Although melatonin is known to be effective as a free radical scavenger and has an anti-cancer effect, carcinogenic properties have also

The present study was carried out to identify the cytochrome P450 enzyme(s) involved in the 6-hydroxylation and O-demethylation of melatonin. The formation kinetics of 6-hydroxymelatonin and N-acetylserotonin were determined using human liver microsomes and cDNA yeast-expressed human enzymes (CYP1A2, 2C9
