Kainate Receptor Antagonist

CNQX (FG9065) is a potent and competitive AMPA/kainate receptor antagonist with IC₅₀s of 0.3 μM and 1.5 μM, respectively. CNQX is a competitive non-NMDA receptor antagonist. CNQX blocks the expression of fear-potentiated startle in rats.

Topiramate (McN 4853) 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.

DNQX (FG 9041), a quinoxaline derivative, is a selective, potent competitive non-NMDA glutamate receptor antagonist (IC₅₀s = 0.5, 2 and 40 μM for AMPA, kainate and NMDA receptors, respectively).

CNQX disodium (FG9065 disodium) is a potent and competitive AMPA/kainate receptor antagonist with IC₅₀s of 0.3 μM and 1.5 μM, respectively. CNQX disodium is a competitive non-NMDA receptor antagonist. CNQX disodium blocks the expression of fear-potentiated startle in rats.

GYKI 52466 dihydrochloride is an orally active, highly selective and noncompetitive AMPA/kainate receptor antagonist with the IC₅₀ values of 7.5 and 11μM, respectively. GYKI 52466 dihydrochloride has good blood brain barrier permeability and anticonvulsant effect. GYKI 52466 dihydrochloride can be used in Parkinson's disease research.

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.

GYKI 52466 is an orally active, highly selective and noncompetitive AMPA/kainate receptor antagonist with the IC₅₀ values of 7.5 and 11μM, respectively. GYKI 52466 has good blood brain barrier permeability and anticonvulsant effect. GYKI 52466 can be used in Parkinson's disease research.

DNQX (FG 9041) disodium salt, a quinoxaline derivative, is a selective, potent competitive non-NMDA glutamate receptor antagonist (IC₅₀s = 0.5, 2 and 40 μM for AMPA, kainate and NMDA receptors, respectively).
