BK-NM-AMT, or βk-NM-αMT, also known as β-keto-N-methyl-αMT or as α,N-dimethyl-β-ketotryptamine, is a serotonin–dopamine releasing agent (SDRA) and putative entactogen of the tryptamine and α-alkyltryptamine families.[1][2][3][4] Along with certain other tryptamines, such as α-ethyltryptamine (αET), 5-chloro-αMT and 5-fluoro-αET, it is one of the few SDRAs known.[5][2]

The drug is the N-methyl and β-keto analogue of α-methyltryptamine (αMT).[2][4] It is a cathinone-like tryptamine and can be thought of as the tryptamine analogue of the phenethylamine methcathinone.[2][4] The EC50Tooltip half-maximal effective concentration values of BK-NM-AMT for monoamine release are 41.3 nM for serotonin and 92.8 nM for dopamine, whereas it only induced 55% release of norepinephrine at a concentration of 10 μM.[2]

BK-NM-AMT was patented by Tactogen in October 2024.[3][4]

Several 5-halogenated derivatives of BK-NM-AMT have also been described and patented.[6] These include BK-5F-NM-AMT,[7][8] BK-5Cl-NM-AMT,[9][10] and BK-5Br-NM-AMT.[11][12] Like BK-NM-AMT, they induce serotonin and dopamine release.[6] In contrast to many other tryptamines however, these novel β-keto-substituted tryptamine derivatives are inactive as agonists of serotonin receptors including the 5-HT1, 5-HT2, and 5-HT3 receptors.[6] In addition, unlike other α-alkyltryptamines like αMT, these compounds are inactive as monoamine oxidase inhibitors (MAOIs).[6]
