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

The proteolytic enzyme beta-secretase (BACE1) plays a central role in the synthesis of the pathogenic beta-amyloid in Alzheimer's disease. Recently, we reported small molecule acylguanidines as potent BACE1 inhibitors. However, many of these acylguanidines have a high polar surface area (e.g. as measured by the topological polar surface area or TPSA), which is unfavorable for crossing the blood-brain barrier. Herein, we describe the identification of the 2-aminopyridine moiety as a bioisosteric replacement of the acylguanidine moiety, which resulted in inhibitors with lower TPSA values and superior brain penetration. X-ray crystallographic studies indicated that the 2-aminopyridine moiety interacts directly with the catalytic aspartic acids Asp32 and Asp228 via a hydrogen-bonding network.
