- Abstract
- Cathinone derivatives are new recreational drugs known to produce psychostimulant effects. However, unlike other psychostimulants, the addictive potential of cathinone derivatives has not been widely studied. Here, we investigated the effects of pentedrone, a type of cathinone derivative, on the dopaminergic system using reverse transcription polymerase chain reaction and Western blot. We also evaluated the addictive potential of pentedrone using conditioned place preference and self-administration. We found that pentedrone increased the mRNA expression of dopamine 1 receptor, dopamine 2 receptor and dopamine transporter, as well as induced phosphorylation of cAMP response element-binding protein in PC-12 cells. Additionally, pentedrone at 3 and 10mg/kg significantly increased conditioned place preference in mice, while pentedrone at 0.3mg/kg/infusion significantly increased self-administration in rats. Finally, we found that acute administration of pentedrone enhanced locomotor activity in a dose-dependent manner. Collectively, these data suggest that the addictive properties of pentedrone may be due to its effects on the dopaminergic system.
