    Description

    TPCA-1 is a potent and selective inhibitor of IKK-2 with IC50 of 17.9 nM. TPCA-1 is an effective inhibitor of STAT3 phosphorylation, DNA binding, and transactivation.

    IC50 & Target[3]

    IKK-2

    17.9 nM (IC50)

    STAT3

     

    In Vitro

    TPCA-1 inhibits lipopolysaccharide-induced human monocyte production of TNF-α, IL-6, and IL-8 with an IC50 of 170 to 320 nM[1][2].
    TPCA-1 (0-2 μM) inhibits STAT3 phosphorylation and transactivation induced by cytokines and nonreceptor tyrosine kinase in dose- and time-dependent manner. TPCA-1 completely inhibits STAT3 phosphorylation without changing total STAT3 levels[3].
    TPCA-1 increased sensitivity to ZD1839 in both TKI sensitive cells and insensitive cells[3].

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

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 7.5 mg/mL (26.85 mM); Clear solution

      This protocol yields a clear solution of ≥ 7.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (75.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 7.5 mg/mL (26.85 mM); Clear solution

      This protocol yields a clear solution of ≥ 7.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (75.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    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.
