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

An extensive fluorine scan of 1,3-oxazines revealed the power of fluorine(s) to lower the pKa and thereby dramatically change the pharmacological profile of this class of BACE1 inhibitors. The CF3 substituted oxazine 89, a potent and highly brain penetrant BACE1 inhibitor, was able to reduce significantly CSF Abeta40 & 42 in rats at oral doses as low as 1 mg/kg. The effect was long lasting, showing a significant reduction of Abeta40 & 42 even after 24 h. In contrast to 89, compound 1b lacking the CF3 group was virtually inactive in vivo.
