Desoxypeganine is primarily used in scientific research for its biological activity, particularly in studies related to enzyme inhibition and neuropharmacology. It serves as a key intermediate in the synthesis of more complex alkaloids with potential therapeutic effects. Due to its structural properties, it is investigated for its interaction with neurotransmitter systems, especially those involving monoamine oxidase (MAO), making it relevant in the development of agents targeting neurological disorders. Its application remains mostly confined to laboratory and preclinical research settings.
