Cas No.:1218-98-0
Sample solution is provided at 25 µL, 10mM.
7,8-Dihydroneopterin is a pteridine with antioxidant activities.[1] It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals in a cell-free assay when used at concentrations ranging from 20 to 100 μM. 7,8-Dihydroneopterin (2-10 μM) inhibits copper ion-induced oxidation of LDL in a cell-free assay and decreases thiobarbituric acid reactive substances (TBARS) produced by THP-1 cells cultured with LDL.[2],[3] It inhibits necrosis induced by oxidized LDL (oxLDL) in U937, but not THP-1, cells when used at a concentration of 200 μM.[4]

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。
