Umibecestat hydrochloride
Based on 1 publication(s) in Google Scholar
Umibecestat hydrochloride (CNP520 hydrochloride) is a selective, orally active BACE inhibitor, with an IC50 of 11 nM for hBACE-1, 10 nM for mouse BACE-1, and 30 nM for hBACE-2. Umibecestat hydrochloride reduces β-Amyloid levels in the brain and cerebrospinal fluid, decreases β-amyloid plaque deposition, and inhibits plaque-associated neuroinflammation. Umibecestat hydrochloride is used in research related to Alzheimer's disease.

In Vitro
Umibecestat hydrochloride is a potent inhibitor of hBACE-1, with a selectivity for BACE-1 that is more than 20000-fold higher than its selectivity for h-Cathepsin D[1].
Umibecestat hydrochloride effectively inhibits Aβ40 secretion in CHO cells transfected with wild-type and Swedish mutant APP[1].
Umibecestat hydrochloride inhibits the hERG potassium channel in in vitro assays, with an IC50 of 3.2 μM[1].
Umibecestat hydrochloride (10 mM; 0.5-30 min) exhibits good in vitro metabolic stability in liver microsomes[2].
Umibecestat hydrochloride is a potent inhibitor of Aβ and sAPPβ release in wild-type APP-overexpressing CHO cells[2].

In Vivo
Following a single oral administration of Umibecestat hydrochloride at a dose of 3.1 mg/kg in beagle dogs, Aβ40 and Aβ42 levels in the cerebrospinal fluid decrease continuously by more than 75% within 12-48 hours, and the compound exhibits high central nervous system distribution efficiency[1].
Umibecestat (3-100 μmol/kg; oral; single dose) hydrochloride produces a dose-dependent reduction in Aβ40 in Sprague-Dawley rats, and the reduction of cerebral Aβ40 reaches 89.1% 4 h after administration at an oral dose of 100 μmol/kg[2].
Umibecestat (200 mg/kg/day; administered daily for 6 months) hydrochloride significantly reduces Aβ levels in the rat brain without altering the histological structure of hippocampal mossy fibers[3].
Umibecestat hydrochloride reduces key pathological features of Alzheimer's disease in APP transgenic mouse models of Alzheimer's disease, including amyloid plaque burden and associated neuroinflammatory markers[2].
