Gentisein is a xanthone that has been found in H. annulatum and has diverse biological activities.1,2,3 It scavenges DPPH radicals and inhibits the activity of α-glucosidase in cell-free assays (IC50s = 23.3 and 14.7 µM, respectively).1,2 Gentisein is cytotoxic against K562 chronic multiple leukemia cells, drug-sensitive HL-60 acute promyelocyte leukemia cells, and multidrug-resistant HL-60/DOX cells (IC50s = 102, 90.9, and 88.3 µM, respectively).3

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。
