2,3-Dimethoxyamphetamine (2,3-DMA), also known as DMA-2, is a drug of the phenethylamine and amphetamine families.12 It is one of the positional isomers of dimethoxyamphetamine.1

2,3-DMA does not appear to have been tested in humans.123

The drug showed weak affinity for serotonin receptors in rat stomach fundus strips (A2 = 2,880 nM).4 In a subsequent study, 2,3-DMA showed very low affinity for the serotonin 5-HT2A and 5-HT2C receptors (Ki = 4,280 nM and >10,000 nM, respectively).5 It did not show activity as a norepinephrine releasing agent in vitro.6 The drug is behaviorally active in mice.2 2,3-DMA did not substitute for DOM in rodent drug discrimination tests.13 However, it did partially substitute for 5-MeO-DMT in these tests.17 As with DOM, the drug did not substitute for dextroamphetamine in drug discrimination tests.89 It produced behavioral disruption at higher doses.89

The chemical synthesis of 2,3-DMA has been described.1

2,3-DMA was first described in the scientific literature by F. Benington and colleagues by 1968.16 Alexander Shulgin first described 2,3-DMA in 1969 but had not yet synthesized it and did not report its effects.10
