Cathinone, a natural amphetamine.

Area of Science:

• Pharmacology
• Neuroscience
• Ethnobotany

Background:

• Khat (Catha edulis) is chewed in East Africa and Arabia for its stimulant properties.
• Cathinone is an alkaloid isolated from the khat plant.
• Cathinone's psychoactive effects have been recognized for approximately fifteen years.

Purpose of the Study:

• To investigate the pharmacological profile of cathinone.
• To compare the central nervous system (CNS) and sympathomimetic effects of cathinone with amphetamine.
• To elucidate the mechanism of action of cathinone.

Main Methods:

• In vitro and in vivo experiments were conducted.
• Pharmacological assays were used to assess CNS and sympathomimetic activity.
• Clinical experiments were performed to evaluate human subjective and objective effects.
• Studies examined cathinone's interaction with catecholamine release.

Main Results:

• Cathinone demonstrated a pharmacological profile similar to amphetamine.
• Animal models showed no distinction between cathinone and amphetamine.
• Clinical studies confirmed cathinone produces amphetamine-like effects in humans.
• Cathinone was found to release catecholamines from presynaptic sites, mirroring amphetamine's mechanism.

Conclusions:

• Cathinone is the primary psychoactive component of the khat leaf.
• Cathinone acts as a natural analogue of amphetamine.
• The findings support cathinone's classification as a natural amphetamine due to shared pharmacological actions and mechanisms.
