    製品説明

    SIS3 is a potent and selective inhibitor of Smad3 with an IC50 of 3 μM for Smad3 phosphorylation. SIS3 inhibits the myofibroblast differentiation of fibroblasts by TGF-β1[1].

    IC50 & Target

    IC50: 3 μM (Smad3 phosphorylation)[1]
    体外実験

    SIS3 (0.3-10 μM; for 1 hour) attenuates the TGF-beta1-induced phosphorylation of Smad3 and interaction of Smad3 with Smad4[1].
    SIS3 (0.1, 10, 50 μM; 30 min) significantly suppresses the expression of FN and α-SMA, but not that of Sphk2 provoked by TGF-β1[2].
    SIS3 (10 μM; 24 hours) significantly reduces both α-SMA and palladin expression that is enhanced by TWEAK in Primary human dermal fibroblasts[3].
    SIS3 significantly inhibits L4 development at five concentrations from as low as 2 μM to 50 μM (5 μM, 10 μM, 20 μM and 50 μM) in a dose-dependent manner[4].

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

    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 (5.10 mM); Clear solution; Need ultrasonic

      This protocol yields a clear solution of 2.5 mg/mL.

      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% Corn Oil

      Solubility: 2.5 mg/mL (5.10 mM); Clear solution; Need ultrasonic

      This protocol yields a clear solution of 2.5 mg/mL. If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, 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.
