A phenol with antioxidant activity
Cas No.:22255-13-6
Sample solution is provided at 25 µL, 10mM.
Quercetin 3-O-α-L-arabinopyranoside is a phenol that has been found in Byrsonima crassa and has antioxidant activity.1,2 It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay (IC50 = 48.6 ?M).1 Quercetin 3-O-α-L-arabinopyranoside inhibits H. pylori-induced oxidative burst of isolated rat polymorphonuclear (PMN) neutrophils (IC50 = 75.3 ?M).2 It reduces N-retinylidene-N-retinylethanolamine- and blue light-induced death of ARPE-19 retinal epithelial cells in a concentration-dependent manner.3 In vivo, quercetin 3-O-α-L-arabinopyranoside (25, 50, and 200 mg/kg) prevents blue light-induced retinal degeneration in a mouse model of macular degeneration.

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。
