From Wikipedia, the free encyclopedia
Cathinone (β-ketoamphetamine) is a monoamine alkaloid found in the shrub Catha edulis (khat) and is chemically similar to ephedrine, cathine and other amphetamines. Amphetamine induces the
release of dopamine from
striatal preparations that are prelabelled either with dopamine or
its precursors, and it has been shown that cathinone also does
this.[1] It is
probably the main contributor to the stimulant effect of Catha edulis.
Cathinone differs from many other amphetamines in that it has a ketone functional
group. Other amphetamines that share this structure include the
antidepressant
bupropion and the
stimulant methcathinone, among others.
Internationally, cathinone is a Schedule I drug under
the Convention on
Psychotropic Substances.[2] Circa
1993, the DEA added cathinone to
the Controlled Substances Act's
Schedule I.
The sale of khat is legal in Israel (although synthetic
cathinone is not), and also in Oman, in Yemen,
in United
Kingdom and in the Horn of Africa.
Chemistry
The molecular structure of cathinone.
Cathinone is structurally related to methcathinone, much like how amphetamine is related
to methamphetamine. Cathinone differs from
amphetamine by possessing a ketone oxygen atom (C=O) on the β (beta)
position of the side chain. The corresponding alcohol compound cathine is a less powerful
stimulant. The biophysiological conversion from cathinone to cathine is to blame for the
depotentiation of khat leaves over
time. Fresh leaves have a greater ratio of cathinone to cathine
than dried ones, therefore having more psychoactive effects.
Cathinone can be extracted from Catha edulis, or
synthesized from α-bromopropiophenone (which is easily made from
propiophenone).
