Abstract
- A series of 2-arylethenyl- N -methylquinolinium derivatives were designed and synthesized based on our previous research of 2-arylethenylquinoline analogues as multifunctional agents for the treatment of Alzheimer's disease (AD) (Eur. J. Med. Chem. 2015, 89, 349–361). The results of in vitro biological activity evaluation, including β-amyloid (Aβ) aggregation inhibition, cholinesterase inhibition, and antioxidant activity, showed that introduction of N -methyl in quinoline ring significantly improved the anti-AD potential of compounds. The optimal compound, compound a12 , dramatically attenuated the cell death of glutamate-induced HT22 cells by preventing the generation of ROS and increasing the level of GSH. Most importantly, intragastric administration of a12 •HAc was well tolerated at doses up to 2000 mg/kg and could traverse blood-brain barrier. [ABSTRACT FROM AUTHOR]
