Synthetic Cathinones

"Synthetic cathinones are related to the parent compound cathinone (Figure 1), one of the psychoactive principals in khat (Catha edulis Forsk). Cathinone derivatives are the β-keto (βk) analogues of a corresponding phenethylamine. The group includes several substances that have been used as active pharmaceutical ingredients (API) of medicinal products, e.g. amfepramone (diethylpropion; Figure 2). Since the mid-2000s, unregulated ring-substituted cathinone derivatives have appeared in the European recreational drugs market. The most commonly available cathinones sold on the recreational market in the period up to 2010 appear to be mephedrone (Figure 3) and methylone (Figure 4). These products are usually encountered as highly pure white or brown powders. Ring-substituted cathinone derivatives are claimed to have effects similar to those of cocaine, amphetamine or MDMA (ecstasy), but little is known of their detailed pharmacology. Apart from cathinone (Figure 1), methcathinone (Figure 5) and two API’s amfepramone (Figure 2) and pyrovalerone, cathinone derivatives are not under international control."
