Rational Design of Dual-Targeting Novel GPE-Derived Oligopeptide Conjugates for Alzheimer's Disease: Synergistic Inhibition of Excitotoxicity and Oxidative Stress.
📄 Abstract
Alzheimer's disease (AD) presents a critical therapeutic gap, necessitating novel multitarget strategies. Excitotoxicity via NMDA receptor overactivation and oxidative stress is a key driver of Tau hyperphosphorylation and neuronal loss. While the tripeptide Gly-Pro-Glu (GPE) derived from IGF-1 exhibits NMDA receptor antagonism, its clinical potential is limited by poor blood-brain barrier penetration and rapid hydrolysis. Herein, we rationally designed three novel GPE-derived oligopeptide conjugates (SAC-PE, SPE, and SAR-SPE) by replacing the N-terminal glycine with antioxidant moieties ((
