A flavonoid with diverse biological activities
Cas No.:855-96-9
Sample solution is provided at 25 µL, 10mM.
Eupatorin is a flavonoid that has been found in L. camara and has diverse biological activities.1,2,3,4 It inhibits the growth of HeLa, MK-1, and B16/F10 tumor cells (GI50s = 15, 58, and 44 ?M, respectively).1 Eupatorin is active against T. cruzi epimastigotes and trypomastigotes (IC50s = 0.2 and 61.8 ?g/ml, respectively) without inducing cytotoxicity in Vero cells (IC50 = >500 ?g/ml).2 It induces vasorelaxation in isolated rat thoracic aortic rings precontracted with phenylephrine (pD2 = 6.66).3 Eupatorin (10 and 100 ?M) reduces nuclear translocation of NF-κB and STAT1α in J774 murine macrophages and reduces paw edema in a mouse model of carrageenan-induced paw inflammation when administered at a dose of 50 mg/kg.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。
