    4-CMTB purchased from MedChemExpress. Usage Cited in: Phytomedicine. 2025 Dec:149:157523.  [Abstract]

    THP (Tetrastigma hemsleyanum polysaccharides, THP) or 4-CMTB (10 mg/kg, i.p., 5 days) improved the Disease Activity Index induced by DSS. However, GLPG0974 (1 mg/kg, i.g., 5 days) reversed the Disease Activity Index increase induced by Tetrastigma hemsleyanum polysaccharides in the IBD mouse model.

    4-CMTB purchased from MedChemExpress. Usage Cited in: Phytomedicine. 2025 Dec:149:157523.  [Abstract]

    THP(Tetrastigma hemsleyanum polysaccharides, THP) or 4-CMTB (10 mg/kg, i.p., 5 days) reduced the expression of these pro-inflammatory mediators (IL-6, IL-1β, TNFα, and MCP-1) in the colon. Conversely, mice administered THP + GLPG0974 (1 mg/kg, i.g., 5 days) displayed an upregulation of colonic cytokine mRNA.

    4-CMTB purchased from MedChemExpress. Usage Cited in: Phytomedicine. 2025 Dec:149:157523.  [Abstract]

    THP (Tetrastigma hemsleyanum polysaccharides, THP)or 4-CMTB (10 mg/kg, i.p., 5 days) reduced the abnormal spleen index induced by DSS and improved the pathological changes in the spleens of mice following DSS treatment. Conversely, in the THP + GLPG0974 group, the abnormal spleen index and spleen inflammation persisted, indicating that GLPG0974 reversed the therapeutic effect of THP.

    4-CMTB purchased from MedChemExpress. Usage Cited in: Phytomedicine. 2025 Dec:149:157523.  [Abstract]

    Immunohistochemical staining images of Ki67 showed that THP (Tetrastigma hemsleyanum polysaccharides, THP) or 4-CMTB (10 mg/kg, i.p., 5 days) regulated the growth and apoptosis of intestinal epithelial cells induced by DSS in mice. However, mice in the THP + GLPG0974 group exhibited persistent damage to intestinal epithelial cells.

    4-CMTB purchased from MedChemExpress. Usage Cited in: Phytomedicine. 2025 Dec:149:157523.  [Abstract]

    THP (Tetrastigma hemsleyanum polysaccharides, THP) or 4-CMTB alleviated the aberrant proliferation of CD3+ cells induced by DSS in mice. However, mice in the THP + GLPG0974 group still exhibited elevated levels of CD3+ cells.

    体外実験

    4-CMTB is both a direct agonist and a positive allosteric modulator of the action of short-chain free fatty acids. 4-CMTB modulates the activity of short-chain fatty acids at FFA2 via the FFA2 second extracellular loop (ECL2)[1][2].

    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 (8.48 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% Corn Oil

      Solubility: ≥ 2.5 mg/mL (8.48 mM); Clear solution

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