Design, synthesis, in vitro and in vivo evaluation of tacrine–cinnamic acid hybrids as multi-target acetyl- and butyrylcholinesterase inhibitors against Alzheimer's disease
vitro cholinesteraseinhibitoryactivities, inhibition of amyloid β-protein self-aggregation, cyto-protective effects against hydrogen peroxide and antiproliferative activity in PC-12 cells. The optimal compounds 35 and 36 are subsequently selected for in vivo assays. 36 shows much better performance in ameliorating the scopolamine-induced cognition impairment and less hepatotoxicity than tacrine.
