Solubility (25°C)* In vitro DMSO 97 mg/mL (198.11 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.500mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Homogeneous suspension
CMC-NA
≥5mg/ml Homogeneous suspension for Oral and Intraperitoneal Injection. Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description CA3 (CIL56) has potent inhibitory effects on YAP1/Tead transcriptional activity and primarily targets YAP1 high and therapy-resistant esophageal adenocarcinoma cells endowed with CSC properties. CA3(CIL56) induces ferroptosis and iron-dependent reactive oxygen species (ROS).
Targets
YAP/TEAD interaction [1]
In vitro

CA3 strongly inhibits esophageal adenocarcinoma cell growth in vitro. CA3 can effectively suppress tumor cell proliferation, induce apoptosis, reduce tumor sphere formation, and the population of ALDH1+ cells. CA3 specially inhibits Tead/YAP1 transcriptional activity but shows no inhibitory activity on other transcriptional factors-Super-TOP/Wnt, CBF1/Notch, and AP-1 after cotransfection of their respective individual promoter luciferases in 293T cells. CA3 preferentially inhibits CSC properties enriched in radiation-resistant esophageal adenocarcinoma cells[1].
In vivo

CA3 exerts strong antitumor activity in xenograft model with no apparent toxicity[1].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    SKGT-4 and JHESO cells

  • Concentrations

    0.5 and 1 μmol/L

  • Incubation Time

    48 hours

  • Method

    SKGT-4 and JHESO cells are seeded onto 6-well plates (1 × 105/well) in DMEM and cultured for 24 hours to allow for cell attachment. The cells are then treated with 0.1% DMSO (control) or CA3 at different doses as indicated for 48 hours. Next, the cells are harvested, fixed with methanol, washed, treated with RNase A, and stained for DNA with propidium iodide, and their DNA histograms and cell-cycle phase distributions are analyzed using flow cytometry.
Animal Study:

[1]
  • Animal Models

    A JHESO xenograft model of esophageal adenocarcinoma

  • Dosages

    1 mg/kg/mouse

  • Administration

    i.p.
