5-Methoxytryptamine (5-MT), also known as mexamine, is a tryptamine derivative closely related to the neurotransmitters serotonin and melatonin. 5-MT has been shown to occur naturally in the body in low levels.[1] It is biosynthesized via the deacetylation of melatonin in the pineal gland.[1]

5-MT acts as a full agonist at the 5-HT1, 5-HT2, 5-HT4, 5-HT6, and 5-HT7 receptors.[2][3][4][5][6][7][8] It has no affinity for the 5-HT3 receptor and its affinity for the 5-HT1E receptor is very weak in comparison to the other 5-HT1 receptors.[5][9] Its affinity for the 5-HT5A receptor is unknown.
