Used in research for treating neurodegenerative disorders, particularly Alzheimer’s disease. Acts as a selective inhibitor of BACE1 (beta-secretase), an enzyme involved in the production of amyloid-beta peptides. By reducing amyloid-beta levels in the brain, it aims to slow or prevent the progression of Alzheimer’s pathology. Studied primarily in preclinical models and early-phase clinical trials to evaluate safety, brain penetration, and biomarker effects. Not approved for commercial use.
