  Ionotropic excitatory amino acid receptor ligands. Synthesis and pharmacology of a new amino acid AMPA antagonist

  摘要：

  We have previously described the potent and selective (RS)-2-amino-3-(3-hydroxy-5-methyl-5-isoxazolyl)propionic acid (AMPA) receptor agonist, (RS)-2-amino-3-(3-carboxy-5-merhyl-4-isoxazolyl)propionic acid (ACPA), and the AMPA receptor antagonist (RS)-2-amino3-[3-(carboxymethoxy)-5-methyl-4-isoxazolyl]propionic acid (AMOA). Using these AMPA receptor ligands as leads, a series of compounds have been developed as tools for further elucidation of the structural requirements for activation and blockade of AMPA receptors. The synthesized compounds have been tested for activity at ionotropic excitatory amino acid (EAA) receptors using receptor binding and electrophysiological techniques, and for activity at metabotropic EAA receptors using second messenger assays. Compounds 1 and 4 were essentially inactive. (RS)-2-Amino-3-[3-(2-carboxyethyl)-5-methyl-4-isoxazoly]propionic acid (ACMP, 2), on the other hand, was shown to be a selective AMPA receptor antagonist (IC50 = 73 mu M), more potent in electrophysiological experiments than AMOA (IC50 = 320 mu M). The isomeric analogue of 2, compound 5, did not show AMPA antagonist effects, but was a weak NMDA receptor antagonist (IC50 = 540 mu M). Finally, compound 3, which is an isomer of ACPA, turned out to be a very weak NMDA antagonist, and an AMPA receptor agonist approximately 1 000 times weaker than ACPA. None of the compounds showed agonist or antagonist effects at metabotropic EAA receptors. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
