OPTIMIZATION AND THERAPEUTIC VALORIZATION OF THE SYMPTOMATIC TREATMENT OF ALZHEIMER'S DISEASE WITH RIVASTIGMINE, GALANTAMINE OR DONEPEZIL, BY SELECTED AMINOTETRAHYDROFURANS ACTING AS MIXED SIGMA-1 / MUSCARINIC LIGANDS
The present invention involves the selected aminotetrahydrofurans AE37, AE37Met, AE14 and their enantiomers as original mixed sigma-1/muscarinic ligands for the optimization of the anticholinesterasic drugs and more specifically of Donepezil, Galantamine or Rivastigmine. Indeed, these aminotetrahydrofurans exhibited M2 and M3 muscarinic antagonisms against the cholinergic adverse effects of these drugs, which constitute the most limitating factor in the use of these drugs against the symptoms of the Alzheimer's disease (AD). Moreover, by their antagonism of the presynaptic muscarinic M2 cholinergic autoreceptors and their very selective sigma-1 agonism they constitute putative agents for the valorization of the anticholinesterasic drugs and more specifically of Donepezil, Galatamine or Rivastigmine from their present status of drugs acting against the symptoms of AD to the perspective of therapeutic agents against the evolution of AD.
