A newly designed molecule J2326 for Alzheimer's disease disaggregates amyloid fibrils and induces neurite outgrowth.

Alzheimer's disease is a neurodegenerative disorder characterized by deposition of β-amyloid (Aβ) fibrils accompanied with progressive neurite loss. None of the clinically approved anti-Alzheimer's agents target both pathological processes. We hypothesized that conjugation of a metal chelator to destabilize Aβ fibrils (fAβs) and a long-chain fatty alcohol to induce neurite outgrowth may generate a novel molecular scaffold that targets both pathologies.

Discovery of N-arylalkyl-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-carboxamide derivatives as HCV NS5B polymerase inhibitors.

The metal ion chelating β-N-hydroxy-γ-ketocarboxamide pharmacophore was integrated into a quinazolinone scaffold, leading to N-arylalkyl-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-carboxamide derivatives as hepatitis C virus (HCV) NS5B polymerase inhibitors. Lead optimization led to the identification of N-phenylpropyl carboxamide 9 k (IC(50) =8.8 μM).
