BACE1-IN-1 is primarily used in research focused on Alzheimer's disease. It acts as an inhibitor of the beta-secretase 1 (BACE1) enzyme, which plays a key role in the production of amyloid-beta peptides. These peptides are associated with the formation of amyloid plaques in the brain, a hallmark of Alzheimer's. By inhibiting BACE1, this compound helps reduce amyloid-beta production, making it a valuable tool for studying potential therapeutic strategies for Alzheimer's and related neurodegenerative conditions. Researchers utilize it to explore mechanisms of amyloidogenesis and to evaluate the efficacy of BACE1 inhibition in preclinical models.
