    SRI-011381 purchased from MedChemExpress. Usage Cited in: Life Sci. 2021 Aug 15;279:119359.  [Abstract]

    The expression of pSmad2/3 in PBMCs treated with Curcumin or SRI-011381 (10 μM) detected by Western blot analysis normalized to GAPDH. SRI-011381 is found to up-regulate the phosphorylation of Smad2/3, while Curcumin reduces the activation of Smad2/3, whereas the inhibitory effect of curcumin in the activation of Smad2/3 is reversed by SRI-011381.

    SRI-011381 purchased from MedChemExpress. Usage Cited in: Mol Med Rep. 2021 Nov;24(5):758.  [Abstract]

    Mimics-exo significantly inhibits the expression levels of TGF-β2 and p-Smad3, as well as downregulated the expression levels of Col-I, Col-III and α-SMA, while SRI-011381 hydrochloride (10 µM) reverses the inhibition of miR-29a-overexpressing hADSCs-exo on the activation of TGF-β2/Smad3 signaling and the fibrosis of HSFBs.

    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 (7.59 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 (7.59 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.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    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.
