Biochem/physiol Actions

Compound 11 (CP11) is an orally active and brain-penetrant delta-secretase (δ-secretase; AEP) inhibitor that selectively blocks AEP (IC50 = 710 nM) but not other related cysteine proteases (Caspase-3/-8 IC50 = 31.86/86.71 μM, Cathepsin-S/-L IC50 >200 μM) via a dual active site-directed and allosteric mode of inhibition. CP11 inhibits Pala cellular AEP activity in cultures (IC50 = 800 nM) and improves cognitive functions in murine models of Alzheimer′s disease (AD) in vivo (10 mg/kg tau P301S or 5xFAD mice via daily p.o.) by reducing tau and APP cleavage, ameliorating synapse loss and augmenting long-term potentiation.
Orally active, brain-penetrant, selective delta-secretase (δ-secretase; AEP) inhibitor that improves cognitive functions in murine models of Alzheimer′s disease (AD).

Translational neurodegeneration, 10(1), 12-12 (2021-04-02)
Currently, there is no cure for Alzheimer's disease (AD). Therapeutics that can modify the early stage of AD are urgently needed. Recent studies have shown that the pathogenesis of AD is closely regulated by an endo/lysosomal asparaginyl endopeptidase (AEP). Inhibition

δ-secretase, also known as asparagine endopeptidase (AEP) or legumain, is a lysosomal cysteine protease that cleaves both amyloid precursor protein (APP) and tau, mediating the amyloid-β and tau pathology in Alzheimer's disease (AD). Here we report the therapeutic effect of

Netrin-1, a family member of laminin-related secreted proteins, mediates axon guidance and cell migration during neural development. T835M mutation in netrin receptor UNC5C predisposes to the late-onset Alzheimer's disease (AD) and increases neuronal cell death. However, it remains unclear how
