Metabolite Identification
Common NameN-Methylserotonin
DescriptionN-Methylserotonin, also known as lopac-m-1514, belongs to the class of organic compounds known as serotonins. Serotonins are compounds containing a serotonin moiety, which consists of an indole that bears an aminoethyl a position 2 and a hydroxyl group at position 5. Chemically, it is a derivative of serotonin in which a methyl group resides at its alkyl amine. N-Methylserotonin is a very strong basic compound (based on its pKa). N-methylserotonin and S-adenosylhomocysteine can be biosynthesized from serotonin and S-adenosylmethionine through the action of the enzyme indolethylamine N-methyltransferase. These include the plants, Actaea racemosa (black cohosh) and Zanthoxylum piperitum, the Green and Golden Bell Frog, Litoria aurea, and Amanita mushrooms. The compound binds to several serotonin receptors, including the 5-HT7 and 5-HT1A receptors, with high affinity (IC50 ≤ 2 nM) and selectivity, and displays agonist activity; besides its direct interaction with the serotonin receptors, N-methylserotonin also acts as a selective serotonin reuptake inhibitor. N-Methylserotonin is not scheduled at the federal level in the United States, but could be considered an analog (of bufotenin), in which case, sales or possession intended for human consumption could be prosecuted under the Federal Analog Act. In humans, N-methylserotonin is involved in tryptophan metabolism. Outside of the human body, N-Methylserotonin has been detected, but not quantified in, citrus. This could make N-methylserotonin a potential biomarker for the consumption of these foods. N-Methylserotonin is a tryptamine alkaloid. Florida N-Methylserotonin is a Schedule I controlled substance in the state of Florida making it illegal to buy, sell, or possess in Florida. It is also called Nω-methylserotonin (Nω-methyl-5-hydroxytryptamine) to distinguish it from tryptamine-derived compounds in which a methyl group is bonded to the nitrogen atom of the indole group.
