Propylcathinone (code name PAL-359), or N-propylcathinone, is a stimulant and designer drug of the amphetamine and cathinone families. It is known to be inactive as a dopamine reuptake inhibitor and releasing agent. Nonetheless, the drug substitutes for dextroamphetamine in animal drug discrimination tests. The related agent propylamphetamine is known to be partially metabolized into amphetamine and this is thought to be involved in its effects. Propylcathinone was first encountered as a novel designer drug in Europe by 2015.
