== 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 ==
This letter describes replacements for the P3 amide moiety present in previously reported tertiary carbinamine macrolactones. Although P-gp efflux issues associated with these amide-macrolactones were solved and full brain penetration was measured in one case, potency was compromised in the process.

Strategies toward improving the brain penetration of macrocyclic tertiary carbinamine BACE-1 inhibitors.,Moore KP, Zhu H, Rajapakse HA, McGaughey GB, Colussi D, Price EA, Sankaranarayanan S, Simon AJ, Pudvah NT, Hochman JH, Allison T, Munshi SK, Graham SL, Vacca JP, Nantermet PG Bioorg Med Chem Lett. 2007 Nov 1;17(21):5831-5.
