| Bioactivity | D-AP4 (D-APB; D-2-Amino-4-phosphonobutyric acid), a phosphono analogue of glutamate, is an NMDA broad spectrum excitatory amino acid receptor antagonist. D-AP4 also is an agonist for a quisqualate-sensitized AP6 site in hippocampus. D-AP4 inhibits AMPA receptor-stimulated 57Co2+ influx in cultured cerebellar granule cells (IC50 ≥ 100 μM)[1][2][3]. |
