Huperzine B
(Synonyms: 石杉碱乙) 目录号 : GC38793An alkaloid with neuroprotective activity
Cas No.:103548-82-9
Sample solution is provided at 25 µL, 10mM.
Huperzine B is an alkaloid originally isolated from H. serrata with neuroprotective activity.1 It selectively binds to acetylcholinesterase (AChE) over butyrylcholinesterase (BChE; IC50s = 8.2 and 157 ?M, respectively).2 It is also an antagonist at the NMDA receptor (IC50 = 316.6 ?M).3 Huperzine B (0.1-100 ?M) increases the viability of PC12 cells in a model of hydrogen peroxide-induced cell injury.1 It increases glutathione peroxidase (GPX) and catalase (CAT) activities, and decreases malondialdehyde (MDA) levels, in PC12 cells in a model of hydrogen peroxide-induced cell injury when used at concentrations ranging from 10 to 100 ?M.

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。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
