    生物活性

    TEPP-46 (ML-265) is a potent and selective pyruvate kinase M2 (PKM2) activator with an AC50 of 92 nM, showing little or no effect on PKM1, PKL and PKR[1].

    体外研究
    (In Vitro)

    TEPP-46 and DASA-58 activate PKM2 by a mechanism similar to that of the endogenous activator FBP. Pre-treatment of cells with TEPP-46 or DASA-58 prevents pervanadate-induced inhibition of PKM2 activity. TEPP-46 also induces a decrease in the intracellular levels of acetyl-coA, lactate, ribose phosphate and serine[1]. TEPP-46 inhibits LPS-induced Hif-1α and IL-1β, as well as the expression of a range of other Hif-1α-dependent genes. TEPP-46 treatment significantly downregulates the expression of the M1 markers Il12p40 and Cxcl-10. Activation of PKM2 using TEPP-46 significantly inhibits FSL-1 and CpG-induced Il1b mRNA expression. TEPP-46 inhibits Mtb-induced Il1b mRNA levels, boosts Mtb-induced levels of Il10 mRNA, and has no effect on levels of Tnf[2].

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

    体内研究
    (In Vivo)

    TEPP-46 exhibits good oral bioavailability with relatively low clearance, long half-life, and good volume of distribution-parameters that predict for drug exposure in tumor tissues. TEPP-46 at 150 mg/kg readily achieves maximal PKM2 activation measured in A549 xenograft tumors[1].

      此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 25.0 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。

    以下溶解方案,请直接配置工作液。建议现用现配,在短期内尽快用完。 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。

    Animal Administration
    [1]

    H1299 parental and H1299 cells with constitutive expression of a mouse PKM1 cDNA (H1299-PKM1 cells) are propagated in RPMI supplemented with 10% fetal bovine serum, 2 mM glutamine, and hygromycin for transgene selection. Cells are harvested, resuspended in sterile PBS, and 5×105 cells are injected subcutaneously into nu/nu mice. Tumor growth is monitored by caliper measurement, the mice are sacrificed and tumors harvested after the time indicated. Tumors are weighed, divided and either flash-frozen in liquid nitrogen or fixed in formalin for later analysis.

    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.
