4-O-Methylhonokiol Attenuated Memory Impairment Through Modulation of Oxidative Damage of Enzymes Involving Amyloid-β Generation and Accumulation in a Mouse Model of Alzheimer's Disease

Abstract

Accumulations of amyloid-β (Aβ) and oxidative damage are critical pathological mechanisms in the development of Alzheimer's disease (AD). We previously found that 4-O-methylhonokiol, a compound extracted from Magnolia officinalis, improved memory dysfunction in Aβ-injected and presenilin 2 mutant mice through the reduction of accumulated Aβ. To investigate mechanisms of the reduced Aβ accumulation, we examined generation, degradation, efflux and aggregation of Aβ in Swedish AβPP AD model (AβPPsw) mice pre-trea…
