Mofegiline hydrochloride is primarily utilized in the field of neuroscience and pharmacology for its role as a selective and irreversible inhibitor of monoamine oxidase type B (MAO-B). This property makes it valuable in research focused on understanding neurodegenerative diseases, particularly Parkinson’s disease, where MAO-B inhibition can help preserve dopamine levels in the brain. It is also studied for its potential neuroprotective effects, which could contribute to slowing the progression of such diseases. Additionally, its application extends to investigating mood disorders and depression, as MAO-B inhibition influences neurotransmitter regulation. In experimental settings, it serves as a tool to explore the biochemical pathways associated with monoamine metabolism and oxidative stress.
