== Function ==
[https://www.uniprot.org/uniprot/BACE1_HUMAN 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.<ref>PMID:10677483</ref> <ref>PMID:20354142</ref>

== Publication Abstract from PubMed ==
The evaluation of a series of bicyclic aminoimidazoles as potent BACE-1 inhibitors is described. The crystal structures of compounds 14 and 23 in complex with BACE-1 reveal hydrogen bond interactions with the protein important for achieving potent inhibition. The optimization of permeability and efflux properties of the compounds is discussed as well as the importance of these properties for attaining in vivo brain efficacy. Compound (R)-25 was selected for evaluation in vivo in wild type mice and 1.5h after oral co-administration of 300mumol/kg (R)-25 and efflux inhibitor GF120918 the brain Abeta40 level was reduced by 17% and the plasma Abeta40 level by 76%.
