  • HY-100781
    D-AP4
    		Antagonist
    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).
  • HY-110234
    Topiramate D12
    		Antagonist
    Topiramate D12 (McN 4853 D12) is a deuterium labeled Topiramate. Topiramate is a broad-spectrum antiepileptic agent. Topiramate is a GluR5 receptor antagonist. Topiramate produces its antiepileptic effects through enhancement of GABAergic activity, inhibition of kainate/AMPA receptors, inhibition of voltage-sensitive sodium and calcium channels, increases in potassium conductance, and inhibition of carbonic anhydrase.
