7-Chloro-4-hydroxyquinoline-2-carboxylic acid (7-Chlorokynurenic acid) 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-Chloro-4-hydroxyquinoline-2-carboxylic acid is also a potent inhibitor of the reuptake of glutamate into synaptic vesicles with a Ki of 0.59 μM. 7-Chloro-4-hydroxyquinoline-2-carboxylic acid has potent antinociceptive actions after neuraxial delivery[1][2].
Male Sprague-Dawley rats pretreated with 7-Chloro-4-hydroxyquinoline-2-carboxylic 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].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
