Umibecestat (CNP520) is a beta-site amyloid precursor protein cleaving enzyme-1 (BACE-1) inhibitor with IC50s of 11 nM and 10 nM for human BACE-1 and mouse BACE-1, respectively[1]. Umibecestat can be used for the research of alzheimer's disease.
Umibecestat (CNP520) is a potent BACE-1 inhibitor that is selective for BACE-1 over other human pepsin-like aspartic proteases, including BACE-2 and cathepsin D[1].
Umibecestat (CNP520) (1.5-51.3 mg/kg; given by oral gavage; 72 hours) shows a dose-dependent effects on Aβ40 and a long duration of action in both rat brain and CSF[1].Umibecestat (CNP520) (3.1 mg/kg; oral administration; 7 days) shows a > 75% reduction on Aβ40 and Aβ42 in CSF after dosing and returns slowly to baseline over the next 7 days[1].
