Function

BACE1_HUMAN Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase.^[1] ^[2]

Publication Abstract from PubMed

The synthesis, evaluation, and structure-activity relationships of a set of related constrained diaminopropane inhibitors of BACE-1 are described. The full in vivo profile of an optimized inhibitor in both normal and P-gp deficient mice is compared with data generated in normal rats.
