6-Hydroxymelatonin

Description6-hydroxy Melatonin is an active metabolite of melatonin . It is formed from melatonin by the cytochrome P450 (CYP) isoform CYP1A2 in human liver microsomes. 6-hydroxy Melatonin is a melatonin 1A (MT1A), MT1B, and MT2 receptor agonist. It inhibits dopamine release from isolated rabbit retina (IC50 = 0.0016 μM). 6-hydroxy Melatonin (10 and 100 μM) reduces increases in the levels of NF-κB, IL-6, and IL-8 and decreases in glutathione (GSH) levels in LPS- and peptidoglycan G-stimulated human umbilical vein endothelial cells (HUVECs) in an in vitro model of sepsis. It reduces iron-induced lipid oxidation in rat hippocampal homogenate when administered at a dose of 10 mg/kg.

UsesA metabolite of Melatonin (M215000).

UsesA major human metabolite of Melatonin

UsesA metabolite of Melatonin (S689050).

Uses6-Hydroxymelatonin has been used as a melatonin derivative to test its protective effects in ultra violet B (UVB)-induced oxidative stress melanocytes and keratinocytes.

General Description6-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.
