Phenserine is primarily investigated for its potential therapeutic applications in neurodegenerative diseases, particularly Alzheimer's disease. It functions as an acetylcholinesterase inhibitor, which helps increase the levels of acetylcholine in the brain, a neurotransmitter crucial for memory and cognitive functions. By enhancing cholinergic activity, it aims to alleviate symptoms of cognitive decline. Additionally, Phenserine has shown promise in reducing the production of amyloid-beta peptides, which are implicated in the formation of plaques in Alzheimer's. Its dual mechanism of action makes it a candidate for not only symptom management but also potentially slowing disease progression. Research continues to explore its efficacy and safety in clinical settings.
