Crystal structure of GRL-8234 bound to BACE (Beta-secretase)Crystal structure of GRL-8234 bound to BACE (Beta-secretase)
Structural highlights
FunctionBACE1_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] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedStructure-based design, synthesis, and biological evaluation of a series of peptidomimetic beta-secretase inhibitors incorporating hydroxyethylamine isosteres are described. We have identified inhibitor 24 which has shown exceedingly potent activity in memapsin 2 enzyme inhibitory (K(i) 1.8 nM) and cellular (IC(50)=1 nM in Chinese hamster ovary cells) assays. Inhibitor 24 has also shown very impressive in vivo properties (up to 65% reduction of plasma A beta) in transgenic mice. The X-ray structure of protein-ligand complex of memapsin 2 revealed critical interactions in the memapsin 2 active site.
