glycine b coagonist site of nmda receptor

7-Chlorokynurenic acid (7-chloro-4-hydroxy-2-carboxyquinoline) 是一种有效的选择性 NMDA 受体拮抗剂，对甘氨酸 B 激动剂位点的 IC50 为 0.56 μM。 7-Chlorokynurenic acid 抑制谷氨酸再摄取到突触小泡中，Ki 为 0.59 μM，并在神经轴输送后显示出镇痛作用。

7-Chlorokynurenic acid sodium salt (7-CKA sodium salt) is a potent and selective antagonist of the glycine B coagonist site of the NMDA receptor (IC50: 0.56 μM). It is also a potent inhibitor of the reuptake of glutamate into synaptic vesicles (Ki: 0.59 μ
