Abstract

A series of scutellarein carbamate derivatives were designed and synthesized based on the multitarget-directed drug design strategy for treatment of Alzheimer's disease. Their acetylcholinesterase and butyrylcholinesterase inhibitory activities, antioxidant activities, metals chelation, and neuroprotective effects against hydrogen peroxide-induced PC12 cell injury were evaluated in vitro. The preliminary results indicated that compound 7b exhibited good inhibitory potency toward AChE and BuChE with IC50 values of 1.2 ± 0.03 μm and 22.1 ± 0.15 μm, respectively, possessed the strong antioxidant potency (10.3 trolox equivalents), as well as acted as a selective metal chelator and neuroprotective agent. Furthermore, 7b could improve memory impairment induced by scopolamine, ethanol, and sodium nitrite using the step-down passive avoidance task in vivo and could remarkably decrease the activity of acetylcholinesterase in mice brain. This study indicated that 7b could be considered as a potential multitarget agent against AD. © 2015 John Wiley & Sons A/S.
