Ebastine-d5
(Synonyms: 依巴斯汀 d5) 目录号 : GC47278An internal standard for the quantification of ebastine
Cas No.:1216953-13-7
Sample solution is provided at 25 µL, 10mM.
Ebastine-d5 is intended for use as an internal standard for the quantification of ebastine by GC- or LC-MS. Ebastine is a potent second generation histamine H1 receptor antagonist (IC50 = 45 nM) that does not cross the blood brain barrier.1 It undergoes extensive first-pass metabolism by hepatic cytochrome P450 3A4 into its active carboxylic acid metabolite, carebastine , which exerts most of the pharmacological effects.2 At 10 μM, ebastine has been shown to inhibit T cell proliferation and the production of Th2-type pro-inflammatory cytokines by macrophages.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。
