    Description

    Ridaforolimus (MK-8669) is a potent and selective mTOR inhibitor; inhibits ribosomal protein S6 phosphorylation with an IC50 of 0.2 nM in HT-1080 cells[1].

    IC50 & Target[1]

    mTOR

     

    In Vitro

    Treatment of HT-1080 fibrosarcoma cells with Ridaforolimus results in a dose-dependent inhibition of phosphorylation of both S6 and 4E-BP1, with IC50s of 0.2 and 5.6 nM, respectively, and EC50s of 0.2 and 1.0 nM, respectively. In HT-1080 cells, the EC50 for inhibition of cell proliferation (0.5 nM) is similar to the EC50s for inhibition of S6 and 4E-BP1 phosphorylation. Exposure to Ridaforolimus reduces the proliferation of cell lines representing a variety of tumor types. Administration of Ridaforolimus to tumor cells in vitro elicit dose-dependent inhibition of mTOR activity with concomitant effects on cell growth and division. Ridaforolimus exhibits a predominantly cytostatic mode of action, consistent with the findings for other mTOR inhibitors. Potent inhibitory effects on vascular endothelial growth factor secretion, endothelial cell growth, and glucose metabolism[1].

    In Vivo

    Ridaforolimus inhibits tumor growth in mice bearing PC-3 (prostate), HCT-116 (colon), MCF7 (breast), PANC-1 (pancreas), or A549 (lung) xenografts. Ridaforolimus inhibits tumor growth in a dose-dependent manner, with 0.3 mg/kg being the lowest dose that inhibits tumor growth significantly and 3 and 10 mg/kg doses achieving maximum inhibition[1].

    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 (2.52 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 (2.52 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.

    Animal Administration
    [1]

    Mice: Animals selected with tumors in the proper size range are assigned to various treatment groups. Ridaforolimus, at dosages of 3 and 10 mg/kg, is administered i.p. on 2 different treatment schedules: (a) daily, 5 continuous days every other week and (b) once weekly. The control group is untreated[1].

    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.
