2,4-Dimethoxyamphetamine (2,4-DMA), also known as DMA-3, is a drug of the phenethylamine and amphetamine families. [1] [2] It is one of the dimethoxyamphetamine (DMA) series of positional isomers. [1] [2]

It was reported by Alexander Shulgin to be active at a dose of 60 mg orally and to produce threshold amphetamine-like stimulant and euphoric effects. [1] [2] However, there was also a "diffusion of association" and Shulgin stated that it was more than just a stimulant. [1] The duration was described as short and effects subsiding at 3 hours. [1] [2] Per Shulgin, the drug could be a full stimulant and/or a full psychedelic at sufficiently high doses, but higher doses were not pursued. [1]

2,4-DMA has been found to act as a low-potency full agonist of the serotonin 5-HT2A receptor, with an EC50 Tooltip half-maximal effective concentration of 2,950 nM and an Emax Tooltip half-maximal effective concentration of 117%. [3] It fully substitutes for DOM in rodent drug discrimination tests. [4] [5] The drug is less potent in this regard than 2,4,5-trimethoxyamphetamine (2,4,5-TMA or TMA-2), but is more potent than 3,4,5-trimethoxyamphetamine (3,4,5-TMA or TMA-1). [4]

2,4-DMA fails to produce stimulus generalization to dextroamphetamine in rodent drug discrimination tests, suggesting that it lacks psychostimulant- or amphetamine-like effects. [6]

Removal of the 2- or 5-position methoxy group in 2,4,5-substituted compounds is also detrimental for their in vivo activity.
