Application

The phosphono amino acid, (RS)-2-amino-3-[5-tert-butyl-3-(phosphonomethoxy)-4-isoxazolyl+ ++]propio nic acid (ATPO) is a competitive antagonist at GluR1-4 (AMPA-preferring) receptors. ATPO is a structural hybrid between the NMDA antagonist (RS)-2-amino-7-phosphonoheptanoic acid (AP7) and the AMPA/GluR5 agonist, (RS)-2-amino-3-(5-tert-butyl-3-hydroxy-4-isoxazolyl)propionic acid (ATPA).

Biochem/physiol Actions

Competitive antagonist at GluR1-4 (AMPA-preferring) receptors.

(RS)-2-Amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA, 5) and the selective AMPA receptor antagonist (RS)-2-amino-3-[3-(carboxymethoxy)-5-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
