O-desmethyl Galantamine is an active metabolite of the alkaloid galantamine .1 It is formed from galantamine by the cytochrome P450 (CYP) isoform CYP2D6.2 O-desmethyl Galantamine inhibits erythrocyte and brain acetylcholinesterase (AChE) and plasma butyrylcholinesterase (BChE; IC50s = 0.12, 0.5, and 24 ?M, respectively). It also prevents decreases in the viability of SH-SY5Y cells induced by hydrogen peroxide, amyloid-β (25-35) , or cobalt chloride when used at concentrations ranging from 6.25 to 100 ?M.3

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。
