General description

A cell-permeable and potent inhibitor that binds to BACE-1 active site and 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 = 230 nM, 7.6 µM and >50 µM for BACE-2, cathepsin D, and renin, respectively).
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). Also available as a 10 mM solution in DMSO (Cat. No. 565794).

Please note that the molecular weight for this compound is batch-specific due to variable water content.
