  Convergent Synthesis and Pharmacology of Substituted Tetrazolyl-2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid Analogues

  摘要：

  The synthesis and pharmacological characterization of 1- and 2-alkyltetrazolyl analogues of (RS)-2-amino-3-[3-hydroxy-5-(2-methyl-2H-5-tetrazolyl)-4-isoxazolyl]propionic acid (2-Me-Tet-AMPA), a highly potent and selective agonist at AMPA receptors, are presented. A shorter and more convergent synthetic route than previously described, employing a new method for introducing the amino acid moiety, was developed for these derivatives. The 2-substituted isomers were selective agonists, and their activity correlated inversely with the size of the substituent. Structural explanations of the structure-activity relationship are provided.
