== Function ==
[[http://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 ==
We describe synthesis and evaluation of a series of cyclic urea derivatives with hydroxylethylamine isostere. Modification of P3, P1, and P2' and combination of SAR display a &gt;100-fold increase in potency with good cellular activity (IC(50)=0.15microM) relative to the previously reported compound 3.
