Alpha-pyrrolidinopentiophenone (α-PVP) is a commonly consumed analogue of pyrovalerone, a synthetic cathinone with psychostimulant properties similar to those of 3,4-Methylenedioxypyrovalerone (MDPV) and cocaine. Since the pharmacology of α-PVP remains scarcely studied, we aimed to evaluate the acute pharmacological effects and its abuse potential in humans after intranasal administration. We...

Methylone is one of the most common synthetic cathinones popularized as a substitute for 3,4-methylenedioxymethamphetamine (MDMA, midomafetamine) owing to its similar effects among users. Both psychostimulants exhibit similar chemistry (i.e., methylone is a β-keto analog of MDMA) and mechanisms of action. Currently, the pharmacology of methylone remains scarcely explored in humans. Herein, we...
