概要
Stilbenes and benzofuran neolignans are important groups of plant phenolics therefore they play a significant role in plants and human health. The objective of this study was to investigate the structure-activity relationships of naturally occurring stilbene and benzofuran neolignan derivatives as acetylcholinesterase inhibitors. A series of these compounds were prepared and assessed for their inhibition on acetylcholinesterase activity. δ-Viniferin, pterostilbene trans-dehydrodimer, pallidol, grossamide, and boehmenan exerted acetylcholinesterase inhibitory potential. The several oligomeric compounds protected against cell damage resulting from t-BHP exposure and inhibited lipopolysaccharide/interferon-gamma (LPS/IFNγ)-induced NO production in vitro. Our findings highlight the great potential of pterostilbene trans-dehydrodimer, pallidol, and boehmenan as multifunctional nutraceuticals for management of neurodegenerative diseases.
