NB-533
NB-533 is an orally active and brain-penetrant BACE-1 inhibitor with a human IC50 of 0.002 μM. NB-533 also inhibits human cathepsin D with an IC50 of 0.001 μM. NB-533 inhibits amyloidogenic amyloid precursor protein (APP) processing and reduces Aβ40 release. NB-533 reduces brain levels of APP metabolite C99 and Aβ40 in transgenic mice. NB-533 can be used for the research of Alzheimer’s disease.

Animal Model:APP51/16 transgenic mice (expressing wild-type human APP under a brain-specific promoter)[1]
-
Dosage:100 μmol/kg
-
Administration:p.o.; at 0 and 3 hours
-
Result:Reached brain levels of 0.53 μmol/kg, with no detectable effect on measured endpoints.
Reached brain levels of 1.5 μmol/kg, resulting in a significant 20% reduction in forebrain C99 and a significant 26% reduction in CSF Aβ40; no significant reduction in brain Aβ40 was observed.
