General description

A cell-permeable isophthalamide compound containing hydroxyethylamine motif that binds to BACE-1 active site and potently blocks its proteolytic activity (IC50 = 15 nM for BACE-1, human and 29 nM for sAPP_NF in HEK293-APPNFEV cells). Displays greater selectivity over other aspartyl proteases (IC50 = 0.23 µM, 7.6 µM and >50 µM for BACE-2, cathepsin D, and renin, respectively). The solid form of this compound (Cat. No. 565788) is also available.

The initial step in the amyloidogenic cascade of amyloid precursor protein (APP) processing is catalyzed by beta-site APP-cleaving enzyme (BACE), and this protease has increased activities in affected areas of Alzheimer's disease brains. We hypothesized that altered APP processing, because
