    Alantolactone purchased from MedChemExpress. Usage Cited in: Stem Cells. 2019 Feb;37(2):190-201.  [Abstract]

    Western blot analyses show the repression of SMC specific markers in the sh-GPM6B TGF-β1 group are abolished by Alantolactone in the sh-GPM6B and the enrichment of SMC specific markers in the GPM6B-sgRNA cells is cancelled by treatment with SB431542.

    Alantolactone purchased from MedChemExpress. Usage Cited in: Stem Cells. 2019 Feb;37(2):190-201.  [Abstract]

    Western blot images show Smad2/3 phosphorylation is lower than baseline in the sh-GPM6B cells and higher than baseline in the GPM6B-sgRNA cells. The phosphorylation of Smad2/3 in the sh-GPM6B TGF-β1 group is elevated by Alantolactone and the phosphorylation is reduced by treatment with SB431542.

    Description

    Alantolactone is a selective STAT3 inhibitor, with potent anticancer activity. Alantolactone induces apoptosis in cancer[1][2][3].

    IC50 & Target

    STAT3

     

    In Vitro

    Alantolactone induces apoptosis in HepG2 cells in a dose-dependent manner. This Alantolactone-induced apoptosis is found to be associated with GSH depletion, inhibition of STAT3 activation, ROS generation, mitochondrial transmembrane potential dissipation, and increased Bax/Bcl-2 ratio and caspase-3 activation[1]. Alantolactone decreases STAT3 translocation to the nucleus, its DNA-binding, and STAT3 target gene expression. Alantolactone significantly inhibits STAT3 activation with a marginal effect on MAPKs and on NF-κB transcription; however, this effect is not mediated by inhibiting STAT3 upstream kinases[2].
    ? Alantolactone induces activin/SMAD3 signaling in human colon adenocarcinoma HCT-8 cells. Alantolactone performs its antitumor effect by interrupting the interaction between Cripto-1 and the activin receptor type IIA in the activin signaling pathway[4].
    ? Alantolactone (5 μg/mL, 24 h) inhibits cell proliferation in colon adenocarcinoma HCT-8 cells[4].

    Cell Line: HCT-8 cells.
    Concentration: 5 μg/mL (~21.6 μM).
    Incubation Time: 24 h.
    Result: Activated the activin signaling pathway in HCT-8 cells.
    In Vivo

    It is found that the average tumor volume in the Alantolactone-treated mice is approximately 2.17-fold lower compared with that in the control mice. However the administration of Alantolactone does not affect the overall bodyweight during the experimental period, suggesting no apparent toxicity. Additionally, the average tumor weight is significantly lower in the Alantolactone-treated mice compared with the control mice. What’s more, the administration of Alantolactone results in a significant decrease in p-STAT3 and cyclin D1 expression in the tumor tissues[2].

    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: ≥ 2.5 mg/mL (10.76 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (10.76 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
