7-Chlorokynurenic acid_product_DataBase

Bioactivity

7-Chlorokynurenic acid (7-CKA) is a potent and selective antagonist of the glycine B coagonist site of the N-methyl-D-aspartate (NMDA) receptor (IC50=0.56 μM). 7-Chlorokynurenic acid is also a potent inhibitor of the reuptake of glutamate into synaptic vesicles with a Ki of 0.59 μM. 7-Chlorokynurenic acid has potent antinociceptive actions after neuraxial delivery[1][2].

Target

Ki: 0.59 μM (reuptake of glutamate)IC50: 0.56 μM (Glycine B coagonist site of NMDA receptor)

In Vivo

Male Sprague-Dawley rats pretreated with 7-Chlorokynurenic acid (10 nM) shows a significant retardation of development of both the electroencephalographic and motor (17.7±2.9 daily stimulations) components of the seizure response[3].
