Sample solution is provided at 25 µL, 10mM.
Demethylwedelolactone (DWL) is a coumestan, originally isolated from E. alba, with diverse biological activities.1,2,3,4 It reduces cytotoxicity induced by CCL4 and galactosamine in rat hepatocytes in a dose-dependent manner.1 DWL inhibits trypsin with an IC50 value of 3.0 μg/ml in vitro.2 It is the major constituent in purified butanolic extracts of E. prostrata which inhibit lethal and hemorrhagic activities of C. rhodostoma venom.3 DWL also inhibits anchorage-independent cell growth of MDA-MB-231 breast cancer cells and decreases the number of lung metastases in an MDA-MB-231 xenograft model in nude mice.4

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。
