BACE-IN-1 is an imidazo[1,2-a]pyridine derivative that inhibits the β-site amyloid precursor protein cleavage enzyme (BACE) sentence.BACE-IN-1 has the potential to investigate diseases involving BACE, such as Alzheimer's disease.

BACE-IN-1 acetate (BACE-IN-1 acetate (350228-37-4,Free base)) has been used as β-site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1) inhibitor in BACE1 inhibitor assay. β-Site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1), an aspartic protease belongs to the protease family of enzymes comprises of six luminal cysteine residues. These residues help in the formation of three intermolecular disulfide bonds and N-linked glycosylation sites.
