[摘要]：A series of novel oxoisoaporphine-based inhibitors (10-aminoalkylamino-1-azabenzanthrone ArNH(CH2)(n)(NRR2)-R-1) of acetylcholinesterase (AChE) has been designed, synthesized, and tested for their ability to inhibit AChE, butyrylcholinesterase (BChE) and AChE-induced beta-amyloid (A beta) aggregation. The synthetic compounds exhibited high AChE inhibitory activity with IC50 values in the submicromolar range in most cases. Non-competitive binding mode was found for these derivatives by the graphical analysis of steady-state inhibition data. Moreover, all compounds exhibit significant inhibitory activity on AChE-induced A beta aggregation with inhibitory potency from 54.5% to 93.5%. Finally, six out of twelve synthetic compounds were predicted to be able to cross the blood-brain barrier (BBB) to reach their targets in the central nervous system (CNS) according to a parallel artificial membrane permeation assay for BBB. The result encourages us to study this class of compounds thoroughly and systematically. (C) 2012 Elsevier Ltd. All rights reserved.
