Discontinued BACE1 Inhibitors in Phase II/III Clinical Trials and AM-6494 (Preclinical) Towards Alzheimer's Disease Therapy: Repurposing Through Network Pharmacology and Molecular Docking Approach.

ABSTRACT: Background: β-site amyloid precursor protein cleaving enzyme 1 (BACE1) inhibitors demonstrated amyloid-lowering efficacy but failed in phase II/III clinical trials due to adverse effects and limited disease-modifying outcomes. This study employed an integrated network pharmacology and molecular docking approach to quantitatively elucidate the multitarget mechanisms of 4 (phase II/III) discontinued BACE1 inhibitors (Verubecestat, Lanabecestat, Elenbecestat, and Umibecestat) and the preclinical compound AM-6494 in Alzheimer's disease (AD). Methods: Drug-associated targets were intersected with AD-related genes to construct a protein-protein interaction (PPI) network, followed by topological analysis to identify hub proteins.
