  Synthesis and Biological Evaluation of NO-Donor-Tacrine Hybrids as Hepatoprotective Anti-Alzheimer Drug Candidates

  摘要：

  In search of safer anti-Alzheimer drugs, 14 NO-donor-tacrine hybrids (1-14) were synthesized and evaluated for their ability to inhibit cholinesterases and for vasorelaxation effects. Compounds 1-13 showed good cholinesterases inhibitory activities in vitro, while 14, particularly, was highly selective, preferring butyrylcholinesterase rather than acetylcholinesterase. Four selected compounds (1, 9, 11, and 14) moderately relaxed the porcine pulmonary arteries in organ bath. In the hepatotoxicity study, significant hepatotoxicity was caused by tacrine but not by 9.

  Hybrid Molecules from Xanomeline and Tacrine: Enhanced Tacrine Actions on Cholinesterases and Muscarinic M₁ Receptors

  摘要：

  A set of amide- and amine-linked hybrid molecules comprising moieties of the orthosteric M-1 muscarinic receptor agonist xanomeline and the cholinesterase inhibitor and allosteric receptor modulator tacrine were prepared with varying spacer length of 10-17 atoms. The hybrids inhibited acetylcholinesterase with similar or higher potency compared to tacrine. M, receptor binding affinity was similar or higher relative to xanomeline and far higher relative to tacrine. Affinities hardly changed when the receptors' orthosteric site was Occupied by all inverse agonist ligand. When Occupied by the orthosteric activator acetylcholine, affinity for the hybrids declined to unmeasureably low levels. Hybrids did not activate M-1 receptors. In vivo studies assaying cognition impairment in rats induced by scopolamine revealed pronounced enhancement of scopolamine action. Taken together, instead of dualsteric (simultaneous allosteric/orthosteric) binding, the hybrids seem to prefer purely allosteric binding at the inactive M-1 receptor.
