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] 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.[4][1]

The drug is the N-methyl and β-keto analogue of α-methyltryptamine (αMT).[1][3] It is a cathinone-like tryptamine and can be thought of as the tryptamine analogue of the phenethylamine methcathinone.[1][3] The EC50 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.[1]
BK-NM-AMT was patented by Tactogen in October 2024.[2][3]
Several 5-halogenated derivatives of BK-NM-AMT have also been described and patented.[5] These include BK-5F-NM-AMT,[6][7] BK-5Cl-NM-AMT,[8][9] and BK-5Br-NM-AMT.[10][11] Like BK-NM-AMT, they induce serotonin and dopamine release.[5] 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.[5] In addition, unlike other α-alkyltryptamines like αMT, these compounds are inactive as monoamine oxidase inhibitors (MAOIs).[5]

Notes: The smaller the value, the more strongly the substance releases the neurotransmitter. See also Monoamine releasing agent § Activity profiles for a larger table with more compounds. |
