(MDPEA), and the prototypical agent of this class is 3,4-methylenedioxy-''N''-methylamphetamine (MDMA; "ecstasy"). Other mentionables include 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxy-''N''-ethylamphetamine (MDEA; "Eve"), ''N''-methyl-1,3-benzodioxolylbutanamine (MBDB; "Eden"), and 3,4-methylenedioxy-''N''-methylcathinone (βk-MDMA; "Methylone").


List of substituted methylenedioxyphenethylamines

The compounds most commonly regarded as comprising the family of MDxx derivatives include:


Related compounds

In addition, there are a number of other compounds that have some structural and pharmacological similarities to the methylenedioxyphenethylamines, and are useful for comparison. These can be broadly divided into (i) compounds where the methylenedioxyphenyl ring is retained but the phenethyl portion is modified, or (ii) compounds which retain the 3,4-cyclised amphetamine core common to the MDxx compounds, but have the 1,3- benzodioxole ring replaced by related heterocycles.
