== 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 ==
Structure-based design of a series of cyclic hydroxyethylamine BACE1 inhibitors allowed the rational incorporation of prime- and nonprime-side fragments to a central core template without any amide functionality. The core scaffold selection and the structure-activity relationship development were supported by molecular modeling studies and by X-ray analysis of BACE1 complexes with various ligands to expedite the optimization of the series. The direct extension from P1-aryl- and heteroaryl moieties into the S3 binding pocket allowed the enhancement of potency and selectivity over cathepsin D. Restraining the design and synthesis of compounds to a physicochemical property space consistent with central nervous system drugs led to inhibitors with improved blood-brain barrier permeability. Guided by structure-based optimization, we were able to obtain highly potent compounds such as 60p with enzymatic and cellular IC(50) values of 2 and 50 nM, respectively, and with &gt;200-fold selectivity over cathepsin D. Pharmacodynamic studies in APP51/16 transgenic mice at oral doses of 180 mumol/kg demonstrated significant reduction of brain Abeta levels.
