melatonin

Melatonin (Melatonine) is a natural hormone secreted by the pineal gland that activates melatonin receptors. Melatonin is a hormone that regulates the biological clock and also has antioxidant and anti-inflammatory activities.

6-Hydroxymelatonin is the main active metabolite and endogenous metabolite of Melatonin via CYP1A2, an agonist of MT2 receptor with antioxidant and neuroprotective effects, and effectively reduces KCN-induced lipid peroxidation and superoxide anion production.

5-Methoxyindole-3-acetic acid (5-Methoxyindoleacetic acid) is a metabolite of Melatonin and is isolated from pineal tissue.

N-Acetyl-5-hydroxytryptamine (O-Demethylmelatonin) , also known as Normelatonin, is the immediate precursor of melatonin. It is produced from serotonin by the enzyme aralkylamine N-acetyltransferase and is converted to melatonin by acetylserotonin O-methyltransferase. It can potently activate TrkB receptor.

Catechol O-methyltransferase (COMT) is a key enzyme in the regulation of melatonin synthesis, which is involved in the regulation of plant growth and development, and can be inhibited by structurally specific heparin oligosaccharides.

Poricoic acid A (Poricoic acid A(F)) is a natural product with antitumor activity. It also enhances melatonin inhibition of AKI-to-CKD transition by regulating the Gas6 AxlNFκB Nrf2 axis.
