General description

N-Acetylserotonin (NAS)/normelatonin acts as a precursor of melatonin in the tryptophan metabolic pathway.

Application

N-Acetyl-5-hydroxytryptamine has been used to treat neuron cells and to analyze its effects on Krüppel-like factor 15 (KLF15) expression.

Biochem/physiol Actions

N-acetyl-serotonin (NAS/normelatonin) can act as a shelter to neurons due to its protecting ability against oxidative challenges. It can also repress the actions of the transcription factor NF-kappaB. NAS possesses antioxidant and antiaging actions. It has protective action against β-amyloid induced neurotoxicity. It helps to maintain the optimal fluidity of the biological membranes.
Immediate precursor of melatonin. It is formed from serotonin and acetyl-CoA in a reaction catalyzed by serotonin N-acetyl transferase, the rate-limiting enzyme in melatonin biosynthesis. This indoleamine is a weak agonist at melatonin receptors, and has moderate effects on G-protein stimulation and inhibition of cAMP accumulation.
