Common Name5-Methoxytryptamine
Description5-Methoxytryptamine, also known as mexamine or 5-MT, belongs to the class of organic compounds known as tryptamines and derivatives. Tryptamines and derivatives are compounds containing the tryptamine backbone, which is structurally characterized by an indole ring substituted at the 3-position by an ethanamine. It is biosynthesized via the deacetylation of melatonin in the pineal gland. 5-MT acts as a full agonist at the 5-HT1, 5-HT2, 5-HT4, 5-HT6, and 5-HT7 receptors. 5-Methoxytryptamine exists in all living organisms, ranging from bacteria to humans. Its affinity for the 5-HT5A receptor is unknown. It has no affinity for the 5-HT3 receptor and is affinity for the 5-HT1E receptor is very weak in comparison to the other 5-HT1 receptors. 5-MT has been shown to occur naturally in the body in low levels.
