Selegiline

Mechanism of action:
Selegiline is a selective monoamine oxidase-B inhibitor. Monoamine oxidase-B is one of the main enzymes responsible for degrading dopamine in the brain. After selegiline binds covalently to monoamine oxidase-B, the enzyme loses its activity, leading to increased dopamine concentrations in the synaptic cleft and enhanced dopaminergic signaling in the striatum.
