Thozalinone (USAN) (brand name Stimsen; former developmental code name CL-39808) is a psychostimulant that has been used as an antidepressant in Europe. It has also been trialed as an anorectic. Thozalinone is described as a "dopaminergic stimulant", and likely acts via inducing the release of dopamine and norepinephrine similarly to its analogues pemoline and aminorex.
