Ligands:	, ,

Function

[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.^[1] ^[2]

Publication Abstract from PubMed

A series of potent hydroxyethyl amine (HEA) derived inhibitors of ss-site APP cleaving enzyme (BACE) was optimized to address suboptimal pharmacokinetics and poor CNS partitioning. This work identified a series of benzodioxolane analogs that possessed improved metabolic stability and increased oral bioavailability. Subsequent efforts focused on improving CNS exposure by limiting susceptibility to Pgp-mediated efflux and identified an inhibitor which demonstrated robust and sustained reduction of CNS ss-amyloid (Ass) in Sprague Dawley rats following oral administration.

Design and preparation of a potent series of hydroxyethylamine containing beta-secretase inhibitors that demonstrate robust reduction of central ss-amyloid.,Weiss MM, Williamson T, Babu-Khan S, Bartberger MD, Brown J, Chen K, Cheng Y, Citron M, Croghan MD, Dineen TA, Esmay J, Graceffa RF, Harried S, Hickman D, Hitchcock SA, Horne DB, Huang H, Imbeah-Ampiah R, Judd T, Kaller MR, Kreiman CR, La DS, Li V, Lopez P, Louie S, Monenschein H, Nguyen TT, Pennington LD, Rattan C, San Miguel T, Sickmier EA, Wahl RC, Wen PH, Wood S, Xue Q, Yang BH, Patel VF, Zhong W J Med Chem. 2012 Apr 2.
