Biochem/physiol Actions
ELND006 is an allosteric γ-secretase inhibitor that selectively blocks amyloid-β (Aβ) over Notch production both in cell-free (Aβ IC50/Notch IC50 = 0.34 nM/6.6 nM) and cell-based assays (Aβ IC50/Notch IC50 = 1.3 nM/85 nM). ELND006 is orally available and blood-brain barrier-permeable (total/unbound conc in brain = 0.12 μM/1.0 nM, 0.52 μM/4.5 nM, 2.1 μM/18 nM and total/unbound conc in plasma = 0.031 μM/0.28 nM, 0.19 μM/1.7 nM, 0.90 μM/8.1 nM 3 h post 1, 3, 10 mg/kg oral dosage in rats, respectively), and shown to effectively reduce cortical Aβx-40 in mice in vivo (by 32%, 48%, and 61% 3 h post 1, 3, 10 mg/kg oral dosage).

Endosomal-autophagic-lysosomal (EAL) dysfunction is an early and prominent neuropathological feature of Alzheimers's disease, yet the exact molecular mechanisms contributing to this pathology remain undefined. By combined biochemical, immunohistochemical and ultrastructural approaches, we demonstrate a link between EAL pathology and the

Alteration of mitochondria-associated membranes (MAMs) has been proposed to contribute to the pathogenesis of Alzheimer's disease (AD). We studied herein the subcellular distribution, the processing, and the protein interactome of the amyloid-β protein precursor (AβPP) and its proteolytic products in

Neurogenesis impairment is considered a major determinant of the intellectual disability that characterizes Down syndrome (DS), a genetic condition caused by triplication of chromosome 21. Previous evidence obtained in the Ts65Dn mouse model of DS showed that the triplicated gene

Herein, we describe our strategy to design metabolically stable γ-secretase inhibitors which are selective for inhibition of Aβ generation over Notch. We highlight our synthetic strategy to incorporate diversity and chirality. Compounds 30 (ELND006) and 34 (ELND007) both entered human
