==Crystal structure of BACE1 in complex with hydroxyethylamine-macrocyclic inhibitor 13==
[[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 a systematic study of how macrocyclization in the P1-P3 region of hydroxyethylamine-based inhibitors of beta-site amyloid precursor protein (APP)-cleaving enzyme (BACE1) modulates in vitro activity. This study reveals that in a number of instances macrocyclization of bis-terminal dienes leads to improved potency toward BACE1 and selectivity against cathepsin D (CatD), as well as greater amyloid beta-peptide (Abeta)-lowering activity in HEK293T cells stably expressing APPSW. However, for several closely related analogs the benefits of macrocyclization are attenuated by the effects of other structural features in different regions of the molecules. X-ray crystal structures of three of these novel macrocyclic inhibitors bound to BACE1 revealed their binding conformations and interactions with the enzyme.
