A serotonin–dopamine releasing agent (SDRA) is a type of drug which induces the release of serotonin and dopamine in the body and/or brain. A closely related type of drug is a serotonin–dopamine reuptake inhibitor (SDRI).

Examples of SDRAs

A number of tryptamine derivatives have been found to act as SDRAs.[1] One such agent is 5-chloro-αMT (PAL-542), which has been reported as having about 64-fold selectivity for dopamine release over norepinephrine release and about 3-fold selectivity for serotonin release over dopamine release, making it a highly selective and well-balanced SDRA.[2] Another agent is 5-fluoro-αET (PAL-545), which has about 35-fold selectivity for dopamine release over norepinephrine release and about 4-fold selectivity for serotonin release over dopamine release.[1] Though selective for inducing the release of serotonin and dopamine over norepinephrine, these agents are not selective monoamine releasers; they have all also been found to be potent agonists of the 5-HT2A receptor, and are likely to act as agonists of other serotonin receptors as well.[1] In any case, they are the only known releaser scaffold that consistently release dopamine more potently than norepinephrine.[3] Another tryptamine SDRA is BK-NM-AMT (α,N-dimethyl-β-ketotryptamine).[3][4][5] It is the N-methyl and β-keto analogue of αMT.[3][4][5] The drug is a cathinone-like tryptamine and can be thought of as the tryptamine analogue of methcathinone.[3][4] Its EC50Tooltip half-maximal effective concentration values 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.[3] BK-NM-AMT has been described in a patent assigned to Tactogen and published in October 2024.[5][4] 5-Halogenated derivatives of this drug, including BK-5F-NM-AMT,[6][7] BK-5Cl-NM-AMT,[8][9] and BK-5Br-NM-AMT,[10][11] have also been described and patented.[12] Like BK-NM-AMT, they induce serotonin and dopamine release.[12] In contrast to many other tryptamines, these compounds are inactive as agonists of serotonin receptors including the 5-HT1, 5-HT2, and 5-HT3 receptors.[12] In addition, unlike other α-alkyltryptamines like αMT, they are inactive as monoamine oxidase inhibitors (MAOIs).[12] 3-Methoxymethcathinone (3-MeOMC) is a rare possible example of a phenethylamine (or rather cathinone) SDRA.[3] Its EC50Tooltip half-maximal effective concentration values for monoamine release are 129 nM for dopamine and 306 nM for serotonin, whereas it only induced 68% release of norepinephrine at 10 μM.[3] However, in another publication, its EC50 for induction of norepinephrine release was reported and was 111 nM.[13][14]
