  Excitatory amino-acid receptor agonists. Synthesis and pharmacology of analogues of 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid

  摘要：

  We have previously proposed the existence of a lipophilic cavity of the 2-amino-3-(3-hydroxy-5-methylisoxazol4-yl)propionic acid (AMPA) receptor recognition site capable of accommodating alkyl substituents of limited size in the 5-position of the isoxazole ring. In order to indirectly elucidate the approximate extent of this proposed cavity we have synthesized and pharmacologically characterized a number of AMPA analogues. For most of these AMPA analogues, a positive correlation between AMPA receptor affinity and agonist effect was observed. The only exception was demethyl-AMPA (8a), which showed relatively high AMPA receptor affinity (IC50 = 0.27 mu M) but remarkably weak agonist potency (EC50 = 900 mu M). Whereas the ethyl analogue of AMPA (Et-AMPA) (IC50 = 0.030 mu M; EC50 = 2.3 mu M) has previously been shown to be slightly more potent than AMPA (IC50 = 0.040 mu M; EC50 = 3.5 mu M), substitutions of a propyl or a butyl group for the methyl group of AMPA to give 8b (IC50 = 0.090 mu M; EC50 = 5.0 mu M) or 8f (IC50 = 1.0 mu M; EC50 = 32 mu M), respectively, result in progressive loss of the AMPA agonist effect. Analogues containing larger groups, such as isopentyl (8e), 1-propylbutyl (8g), 2,2-dimethylpropyl (8h), or benzyl (14) groups, were very weak or totally inactive as AMPA receptor ligands.

  methyl-4-isoxazolyl]propionic acid (AMOA, 7) have been used as leads for the design and synthesis of a number of potential AMPA receptor antagonists. Two parallel series of AMOA analogs were synthesized, containing either a distal carboxylic acid (compounds 8b-g and 11b) or a phosphonic acid (compounds 9a-g, 10c, and 11c). Pharmacological characterization of the synthesized compounds was carried out
