7-Chloro-ñ-methyltryptamine (7-Cl-AMT) is a tryptamine derivative with stimulant effects, invented in the 1960s. It is a weak monoamine oxidase inhibitor but its pharmacology has not otherwise been studied by modern techniques, though several closely related compounds are known to act as serotoninâÂÂdopamine releasing agents and agonists of the 5-HT<sub>2A</sub> receptor.
