Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.65mg/ml Taking the 1 mL working solution as an example, add 50 μL of 13 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; 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. 
Clear solution
5% DMSO 95% Corn oil
0.33mg/ml Taking the 1 mL working solution as an example, add 50 μL of 6.6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <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 HO-3867, an analog of curcumin, is a selective STAT3 inhibitor that inhibits its phosphorylation, transcription, and DNA binding without affecting the expression of other active STATs. HO-3867 induces apoptosis.
Targets
STAT3 [1]
In vitro HO-3867 produces significant cytotoxicity in A2780 and other tested ovarian cancer cell lines, with less toxic to noncancerous ovarian surface epithelial cells. HO-3867 induces G(2)-M cell cycle arrest in A2780 cells and promotes apoptosis by caspase-8 and caspase-3 activation. HO-3867 blocks the JAK/STAT3 pathway in human ovarian cancer cell lines. [1]
In vivo HO-3867 (100 ppm p.o.) inhibits the growth of ovarian cancer xenograft tumor in mice without any apparent signs of toxicity, and also results in inhibition of pSTAT3 as well as downregulation of the STAT3-targeting proteins. [1] HO-3867 sensitizes cisplatin-resistant ovarian carcinoma through STAT3 inhibition. [2] HO-3867 (100 ppm p.o.) also attenuates left-heart-failure-induced pulmonary hypertension by decreasing oxidative stress and increasing PTEN expression in the lung of rats. [3]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    A2780 (A2780R), PA-1, SKOV3, OV4, and OVCAR3 cells; human ovarian surface epithelial cell

  • Concentrations

    ~20 μM

  • Incubation Time

    24 hours

  • Method

    Cell viability is determined by a colorimetric assay using MTT. In the mitochondria of living cells, yellow MTT undergoes a reductive conversion to formazan, producing a purple color. Cells, grown to ~80% confluence in 75-mm flasks, are trypsinized, counted, seeded in 96-well plates with an average population of 7,000 cells/well, incubated overnight, and then treated with HO-3867 for 24 h. All experiments are done using 8 replicates and repeated at least three times.
Animal Study:

[1]
  • Animal Models

    Mice bearing ovarian cancer A2780 tumor xenografts

  • Dosages

    ~100 ppm

  • Administration

    p.o.
