Cas No.:13441-51-5
Sample solution is provided at 25 µL, 10mM.
D-Kynurenine is an antagonist of hydroxycarboxylic acid receptor 3 HCA3/GPR109B (EC50 = 2.61 μM in a luciferase reporter assay) and a metabolite of D-tryptophan.1 It increases levels of intracellular calcium and decreases forskolin-stimulated production of cAMP in CHO cells expressing human HCA3/GPR109B when used at concentrations of 10 and 100, or 1,000 μM, respectively. D-Kynurenine (10 μM) increases expression of vimentin and decreases expression of E-cadherin in 95D lung cancer cells.2 It has been used as a substrate in fluorometric assays for D-amino acid oxidase activity.3,4

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。
