Used primarily in scientific research as a selective and irreversible inhibitor of monoamine oxidase B (MAO-B), it helps study neurotransmitter metabolism, particularly dopamine. This makes it valuable in models of neurodegenerative diseases like Parkinson’s, where dopamine regulation is critical. It is also employed to investigate the role of MAO-B in aging and oxidative stress in neural tissues. Due to its irreversible binding, it allows for long-lasting enzyme suppression in experimental settings. Not used clinically, but serves as a tool compound in pharmacological and neurochemical studies.
