体外実験

SKI II inhibits cell proliferation by suppressing the Wnt/β-catenin signaling pathway. SKI II promotes the degradation of β-catenin by enhancing Wnt5A[1].
? SKI II (1.25 μM, 48 h) in combination with DDP has a clear synergistic effect in human gastric carcinoma SGC7901/DDP cell line[2].

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

体内実験

Chronic SKI II (50.0 mg/kg, 3-weekly i.p. for 16 weeks) administration leads to permanent reduction of S1P concentrations in plasma in mice[3].
? SKI II (50.0 mg/kg, IP; 100 mg/kg, PO) treatment reduces tumor growth in mice bearing solid tumor model[4].

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

Animal Model: 8 week-old female LDL-R-/- mice[3].
Dosage: 50.0 mg/kg.
Administration: IP injection daily, 3 days a week for 16 weeks.
Result: A single administration of produced a significant reduction of plasma S1P with the maximum (~40%) observed 12 h after injection. At sacrifice (72 h after last injection) S1P levels were 266 ± 18 ng/mL and 328 ± 30 ng/mL in the SKI-II-treated and control groups, respectively.
Animal Model: BALB/c mouse solid tumor model that uses JC mammary adenocarcinoma cells[4].
Dosage: 50.0 mg/kg.
Administration: IP injection daily, 3 days a week for 16 weeks.

Animal Model: BALB/c JC tumor model[4].
Dosage: 100 mg/kg.
Administration: PO every other day.
Result: Caused significant antitumor activity in well-established tumors as early as day 5, with maximal response seen at the end of the study. Showed 79% inhibition of tumor growth from the start of treatment.

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: ≥ 2.75 mg/mL (9.08 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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: ≥ 2.75 mg/mL (9.08 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.
