    生物活性

    Tomivosertib (eFT508) is a potent, highly selective, and orally active MNK1 and MNK2 inhibitor, with IC50s of 1-2 nM against both isoforms. Tomivosertib (eFT508) treatment leads to a dose-dependent reduction in eIF4E phosphorylation at serine 209 (IC50=2-16 nM) in tumor cell lines[1]. Tomivosertib (eFT508) also dramatically downregulates PD-L1 protein abundance[2].

    体外研究
    (In Vitro)

    Tomivosertib (eFT508) 以剂量依赖性方式在肿瘤细胞系中抑制 eIF4E 在丝氨酸 209 的磷酸化 (IC50=2-16 nM) 。在约 50 种血液癌症细胞系的筛选中,Tomivosertib 对多个 DLBCL 细胞系显示出抗增殖活性。Tomivosertib 在 TMD8、OCI-Ly3 和 HBL1 DLBCL 细胞系中对促炎细胞因子 (如 TNFα、IL-6、IL-10 和 CXCL10) 的产生呈剂量依赖性减少。进一步评估表明,TNFα mRNA 半衰期减少两倍与 TNFα 产生减少相关[1].

    体内研究
    (In Vivo)

    Tomivosertib (eFT508) 在 TMD8 和 HBL-1 ABC-DLBCL 模型中表现出显著的抗肿瘤活性,这两种模型均携带激活型 MyD88 突变。此外,Tomivosertib 在人类淋巴瘤模型中与 R-CHOP 的成分以及新型靶向药物 (如 PCI-32765 和 Venetoclax) 联合应用效果良好[1]

    动物实验:

    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

      请依序添加每种溶剂: 10% DMSO    90% Corn Oil

      Solubility: ≥ 0.44 mg/mL (1.29 mM); 澄清溶液

      此方案可获得 ≥ 0.44 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

      1 mL 工作液为例,取 100 μL 4.4 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

    • 方案 二

      请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 0.43 mg/mL (1.26 mM); 澄清溶液

      此方案可获得 ≥ 0.43 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 4.3 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。

    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.
