A catecholamine (/ ˌ k æ t ə ˈ k oʊ l ə m iː n /; CA) is a monoamine, an organic compound that has a catechol (benzene with two hydroxyl side groups at carbons 1 and 2) and a side-chain amine. N,N-Dimethyltryptamine (DMT or N,N-DMT) is a psychedelic compound of the tryptamine family. Since DMT resembles the basic structure of neurotransmitters, when ingested, DMT is able to cross the human blood-brain-barrier, allowing it to act as a powerful hallucinogenic drug that dramatically affects human consciousness.

Indolethylamine-N-methyltransferase (INMT) is a Class 1 transmethylation enzyme known for its production of N,N-dimethyltryptamine (DMT), a hallucinogen with affinity for various serotonergic, adrenergic, histaminergic, dopaminergic, and sigma-1 Phenylethanolamine N-methyltransferase (PNMT) is an enzyme found primarily in the adrenal medulla that converts norepinephrine (noradrenaline) to epinephrine (adrenaline). It is also expressed in small groups of neurons in the human brain.

It is found in human blood and cerebrospinal fluid, and its formation has been proposed to occur in adrenal and lung, where high levels of the enzyme responsible for its synthesis—indole-N-methyltransferase (INMT)—have been reported. 20 DMT is the only mammalian N,N-dimethylated trace amine known 20 –25 and the physiological functions of endogenous DMT remain unclear.
