α-Methylmelatonin, also known as α-methyl-5-methoxy-N-acetyltryptamine, is a synthetic tryptamine derivative and analogue of the monoamine neurotransmitter melatonin. [1] It is a metabolite of α-methyltryptophan, α-methyl-5-hydroxytryptophan, and α-methylserotonin that can be formed in small amounts via aralkylamine N-acetyltransferase (AANAT).
