3-Methyl-4,5-methylenedioxyamphetamine (5-Methyl-MDA) is a ring-methylated derivative of the entactogenic drug MDA and a structural isomer of MDMA. It substitutes for MDA in animal tests and in vivo testing showed that 5-methyl-MDA is both several times more potent and much more selective as a releaser of serotonin over the other monoamines dopamine and noradrenaline compared to MDA itself. The other isomer 2-methyl-MDA is also more potent than MDA, although less potent than 5-methyl-MDA,[1] but both 6-methyl-MDA and the 6-methyl derivative of MDMA, Madam-6, are inactive, most likely due to steric hindrance.[2] More recent research has used these animal activity results of the effects of ring-methylation to help guide computer modeling of the serotonin transporter complex.[3] Anecdotal reports from human users suggest that 5-methyl-MDA produces MDMA-like effects but is several times more potent by weight, and with mainly stimulant and less empathogenic effects.
