Buphedrone, also known as β-keto-N-methylphenylisobutylamine, is a stimulant of the phenethylamine and cathinone chemical classes that was first synthesized in 1928.[1] It is a synthetic analogue of cathinone, a stimulant naturally occurring in the khat plant. Like many other synthetic cathinones (e.g. mephedrone), it is also found in so called "legal highs" (sometimes also called "bath salts"), a class of designer drugs used to bypass legal restrictions.[2]

Pharmacology

Buphedrone is a substituted cathinone, and more broadly related, a substituted amphetamine and substituted phenethylamine and, as such, operates as a norepinephrine-dopamine releasing agent, similar to many of the drugs in its chemical class(es).

Chemistry

Buphedrone is a β-ketone and is related to the naturally occurring compounds cathinone and cathine. It is also related to methamphetamine, differing by the β-ketone substituent (at the β-carbon) and an ethyl group replacing the methyl group at the carbon at the α-position relative to the amine. Another name for buphedrone is phenylacetoethyl-methylamine.

Buphedrone as free base is very unstable; it is prone to dimerization like other α-amino ketones. Because of this, it is sold as various salts, with a hydrochloride being most common.

Effects

Buphedrone increases spontaneous rodent locomotor activity,[3] potentiates the release of dopamine from dopaminergic nerve terminals in the brain,[4] and causes appetite suppression. It also causes a possibly dangerous effect of decreasing subjective feeling of thirst. Though the specific effects and toxicity of buphedrone are not well studied,[5] in general it is expected to have overlapping effects with other synthetic cathinones.[6]

As of October 2015, buphedrone is a controlled substance in China.[7]

Buphedrone is an Anlage II controlled drug in Germany.

In the United States, buphedrone is considered a schedule 1 controlled substance as a positional isomer of mephedrone.[8]
