Metabolite Identification
Common Name5-Methoxytryptamine
Description5-Methoxytryptamine, also known as 5-meot or mexamine, 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-MT has been shown to occur naturally in the body in low levels. 5-Methoxytryptamine is a very strong basic compound (based on its pKa). 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-Methoxytryptamine exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 5-Methoxytryptamine has been detected, but not quantified in, milk (cow). This could make 5-methoxytryptamine a potential biomarker for the consumption of these foods. Its affinity for the 5-HT5A receptor is unknown.
