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].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
