Desmethylselegiline (DMS), also known as norselegiline or as N-propargyl-L-amphetamine, is an active metabolite of selegiline, a medication used in the treatment of Parkinson's disease and depression.

Like selegiline, DMS is a monoamine oxidase inhibitor (MAOI); specifically, it is a selective and irreversible inhibitor of monoamine oxidase B (MAO-B). In addition, it is a catecholaminergic activity enhancer (CAE) similarly to selegiline. The drug also produces levoamphetamine as an active metabolite, which is a norepinephrine–dopamine releasing agent with sympathomimetic and psychostimulant effects.

DMS has been studied much less extensively than selegiline and has not been developed or approved for medical use.
