    生物活性

    Oleandrin (PBI-05204) inhibits the Na+, K+-ATPase activity with an IC50 of 620 nM.

    IC50 & Target

    IC50: 620 nM (Na+, K+-ATPase)[1].

    体外研究
    (In Vitro)

    Study of Na,K-ATPase inhibition shows an IC50 (nM) of 620 for Oleandrin. The inhibition of Na,K-ATPase by Oleandrin confirms that it likely exert its toxic effect through inhibition of sodium pump activity[1]. When treated with a series of concentrations of Oleandrin (0.2-25 nM), the undifferentiated CaCO-2 cells are sensitive as evidenced by an IC50 of 8.25 nM. In contrast, a maximum growth inhibition of only 20% is reached in differentiated CaCO-2 cells even though they are treated with Oleandrin concentrations as high as 25 nM[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    体内研究
    (In Vivo)

    The effect of Oleandrin is investigated on glioma growth in vivo. To this aim, SCID or C57BL/6 mice are transplanted, respectively, with human U87MG (5×104), U251, GBM19 (5×105), or murine (syngeneic) GL261 (7.5×104) cells into the right striatum and, after 10 d, treated daily with intraperitoneal Oleandrin for an additional 7 d. Oleandrin significantly reduces tumor sizes in human and murine glioma cell models in vivo in a dose-dependent way. High concentrations of Oleandrin (3 mg/kg) are fatal in both models, as expected from the known lethal dose for rodents. Doses of Oleandrin below the lethal dose (0.3 mg/kg) significantly increase the survival time from 32.6±1.4 d to 53.8±9.6 d in mice injected with U87MG cells (n=5-11; p<0.01, log-rank test) and from 23.37±1.2 d to 34.38±3.3 d (n=5-11; p<0.01, log rank test) in mice injected with GL261 cells[3].

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
    ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

    • 方案 一

    Cell Assay
    [2]

    Undifferentiated wild-type and well-differentiated CaCO-2 cells are treated with a range of concentrations of Oleandrin (0.2-25 nM). After 48 h, cells are labeled with BrdU and relative cell proliferation is determined with a BrdU Cell Proliferation Kit[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [3]

    Mice[3]
    After tumor cell injection, SCID or C57BL/6 mice are monitored daily. The end point is determined by lack of physical activity or death. The mean survival time is calculated using the Kaplan-Meier method and statistical analysis is performed using a log-rank test. For cotreatment with Temozolomide (TMZ), 10 d after tumor injection, mice are treated with Oleandrin (0.03, 0.3, or 3 mg/kg/daily, i.p.), TMZ (50 mg/kg, i.p., every 2 d for a total of 4 times with a stop of 2 weeks) or both. The dosing scheme is chosen starting from these data to be reasonably sure that a constant concentration of drug is maintained along the experiment. Animals used in Kaplan-Meier survival studies receive up to four TMZ cycles.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
