Metabolite Identification

Common Name

N-Acetylserotonin

Description

N-Acetylserotonin (NAS), also known as normelatonin, is a naturally occurring chemical precursor and intermediate in the endogenous production of melatonin from serotonin. It also has biological activity in its own right, including acting as a melatonin receptor agonist, an agonist of the TrkB, and having antioxidant effects. N-Acetylserotonin is an intermediate in the metabolic pathway of melatonin and indoleamine in the pineal gland of mammalians. Serotonin-N-acetyltransferase (SNAT), which regulates the rate of melatonin biosynthesis in the pineal gland, catalyzes the acetylation of 5HT to N-acetylserotonin (NAS). A methyl group from S-adenosylmethionine is transferred to NAS by hydroxyindole-O-methyltransferase (HIOMT), and finally NAS is converted to 5-methoxy-N-acetyltryptamine, or melatonin. In most mammalian species the content of NAS (and melatonin) in the pineal gland shows clear circadian changes with the highest level occurring during the dark period. This elevation of the contents of NAS (and melatonin) in the dark period is due to the increase of SNAT activity and the elevation of SNAT gene expression. Experimental studies show that N-acetylserotonin possess free radical scavenging activity. Acute administration of irreversible and reversible selective MAO-A inhibitors and high doses (or chronic administration of low doses) of relatively selective MAO-B inhibitors (but not of highly selective MAO-B inhibitors) suppressed MAO-A activity and stimulated N-acetylation of pineal serotonin into N-acetylserotonin, the immediate precursor of melatonin. N-acetylserotonin increase after MAO-A inhibitors might mediate their antidepressive and antihypertensive effects. N-Acetylserotonin is the product of the O-demethylation of melatonin mediated by cytochrome P-450 isoforms: Cytochrome p450, subfamily IIc, polypeptide 19 (CYP2C19, a clinically important enzyme that metabolizes a wide variety of drugs), with a minor contribution from Cytochrome p450, subfamily I, polypeptide (2CYP1A2, involved in O-deethylation of phenacetin). (PMID 15616152 , 11103901 , 10721079 , 10591054 ). N-Acetylserotonin acts as a potent antioxidant, NAS effectiveness as an anti-oxidant has been found to be different depending on the experimental model used, it has been described as being between 5 and 20 times more effect than melatonin at protecting against oxidant damage. NAS has been shown to protect against lipid peroxidation in microsomes and mitochondria. NAS has also been reported to lower resting levels of ROS in peripheral blood lymphocytes and to exhibit anti-oxidant effects against t-butylated hydroperoxide- and diamide-induced ROS.

Enzymes

Enzyme Details

1. Serotonin N-acetyltransferase

General function:: Involved in N-acetyltransferase activity
Specific function:: Controls the night/day rhythm of melatonin production in the pineal gland. Catalyzes the N-acetylation of serotonin into N-acetylserotonin, the penultimate step in the synthesis of melatonin.
Gene Name:: AANAT
Uniprot ID:: Q16613
Molecular weight:: 23343.8

Reactions

Acetyl-CoA + Serotonin → Coenzyme A + N-Acetylserotonin	details

Enzyme Details

2. Acetylserotonin O-methyltransferase

General function:: Involved in O-methyltransferase activity
Specific function:: Isoform 1 catalyzes the transfer of a methyl group onto N-acetylserotonin, producing melatonin (N-acetyl-5-methoxytryptamine). Isoform 2 and isoform 3 lack enzyme activity.
Gene Name:: ASMT
Uniprot ID:: P46597
Molecular weight:: 41660.34

Reactions

S-Adenosylmethionine + N-Acetylserotonin → S-Adenosylhomocysteine + Melatonin	details
