Synthesis and evaluation of paeonol derivatives as potential multifunctional agents for the treatment of Alzheimer's disease.

ABSTRACT: Alzheimer's disease (AD) is a progressive neurodegenerative brain disorder characterized by memory loss, language impairment, personality changes and intellectual decline. Taking into account the key pathological features of AD, such as low levels of acetylcholine, beta-amyloid (Aβ) aggregation, oxidative stress and dyshomeostasis of biometals, a new series of paeonol derivatives 5a-5d merging three different functions, i.e., antioxidant, anti-acetylcholinesterase (AChE) activity, metal chelating agents for AD treatment have been synthesized and characterized. Biological assays revealed that compared with paeonol (309.7 μM), 5a-5d had a lower DPPH IC50 value (142.8-191.6 μM). 5a-5d could significantly inhibit hydrogen peroxide-induced neuronal PC12 cell death assessed by MTT assay in the c
