应用
CNQX二钠盐水合物用作：
- 神经元培养物中的竞争性非NMDA受体拮抗剂和竞争性 AMPA/红藻氨酸受体拮抗剂（110）
- 谷氨酸能阻滞剂，测量投射神经元的抑制性突触后电流（111）
- AMPA谷氨酸受体拮抗剂，用于前额叶皮层神经元（112）
生化/生理作用
CNQX（6-氰基-7-硝基喹喔啉-2,3-二酮）是强效、竞争性 AMPA/红藻氨酸受体拮抗剂。它是喹喔啉衍生物，也是非N-甲基-d-天冬氨酸（非-NMDA）谷氨酸受体拮抗剂。CNQX 通过 α-氨基-3-羟基-5-甲基异恶唑-4-丙酸受体（AMPAR）介导丘脑网状核去极化。 显示出对 AMPA/红藻氨酸受体具有微摩尔亲和力。
强效、竞争性 AMPA/红藻氨酸受体拮抗剂。

NMDA-type glutamate receptors mediate both trophic and excitotoxic signalling in CNS neurons. We have previously shown that blocking NMDAR- post-synaptic density-95 (PSD95) interactions provides significant protection from excitotoxicity and in vivo ischaemia; however, the mechanism of neuroprotection is unclear.
