Yohimbine
(Synonyms: 育亨宾) 目录号 : GC37952An α2-adrenoceptor antagonist
Cas No.:146-48-5
Sample solution is provided at 25 µL, 10mM.
Yohimbine is a natural alkaloid that has highest affinity for α2-adrenergic receptors (pKis = 8.2, 8.7, and 9.6 for human α2A, α2B, and α2C, respectively), with antagonist activity at these receptors.1,2 It less potently antagonizes serotonin 5-HT1 receptors (pKis = 7.3, 6.8, and 7.6 for human HT1A, HT1B, and HT1D, respectively) and α1-adrenergic receptors (pKis = 6.7, 6.8, and 6.8 for human α1A, α1B, and α1D, respectively).1 Yohimbine is used in veterinary medicine to reverse the sedative effects of α2-agonists.

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。
