Ethylone, also known as 3,4-methylenedioxy-N-ethylcathinone (MDEC, bk-MDEA), is an entactogen, stimulant, and psychedelic of the phenethylamine, amphetamine, and cathinone chemical classes. It is the β-keto analogue of MDEA ("Eve"). Ethylone has only a short history of human use and is reported to be less potent than its relative methylone. Very little data exists about the pharmacological properties, metabolism, and toxicity of ethylone.


Analysis of human and rat urine for the metabolites of bk-amphetamines suggested that ethylone was degraded in the following metabolic steps:[1]

  1. N-deethylation to the primary amine.
  2. Reduction of the keto moiety to the respective alcohol.
