DL-threo-β-Hydroxyaspartic acid is an inhibitor of excitatory amino acid transporters (EAATs).1,2 It inhibits glutamate uptake in COS-1 cells expressing human EAAT1 or EAAT2 (IC50s = 96 and 31 µM, respectively) as well as inward currents induced by L-aspartate in EAAT4-expressing Xenopus oocytes (Ki = 0.6 µM) and by L-glutamate in EAAT5-expressing oocytes (Ki = 2.5 µM) voltage-clamped at -60 mV. Intrathecal administration of DL-threo-β-hydroxyaspartic acid (7.5 and 15 µg/animal) reduces the number of flinches and shakes in the second phase of the formalin test in rats.3

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。
