Specific Targeting of Acetylcholinesterase and Butyrylcholinesterase Recognition Sites. Rational Design of Novel, Selective, and Highly Potent Cholinesterase Inhibitors
摘要:
Tacrine-based AChE and BuChE inhibitors were designed by investigating the topology of the active site gorge of the two enzymes. The homobivalent ligands characterized by a nitrogen-bridged atom at the tether level could be considered among the most potent and selective cholinesterase inhibitors described to date. The nitrogen-containing homobivalent ligands 3e,g and the sulfur-containing 3h validated the hypothesis of extra sites of interaction in the AChE and BuChE active site gorges.
