Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 71 mg/ml 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. 
Clear solution
5% DMSO 95% corn oil
3.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of 71 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 BO-264 is a potent and orally active inhibitor of transforming acidic coiled-coil 3 (TACC3) with IC50 of 188 nM and Kd of 1.5 nM. BO-264 specifically blocks the function of FGFR3-TACC3 fusion protein. BO-264 induces SAC-dependent mitotic arrest, apoptosis and DNA damage with antitumor activities.
Targets
FGFR3 [1] TACC3 [1]
(Cell-free assay)		 TACC3 [1]
(Cell-free assay)
1.5 nM(Kd) 188 nM
In vitro

BO-264 significantly decreases centrosomal TACC3 during both mitosis and interphase. BO-264 displays potent anti-proliferative activity in the NCI- 60 cell line panel compromising nine different cancer types. BO-264 significantly inhibits the growth of cells harboring FGFR3-TACC3 fusion, an oncogenic driver in diverse malignancies.[1]
In vivo

BO-264's oral administration significantly impairs tumor growth in immunocompromised and immunocompetent breast and colon cancer mouse models, and increases survival without any major toxicity.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    JIMT-1 cells

  • Concentrations

    1 μM

  • Incubation Time

    6 h

  • Method

    Briefly, JIMT-1 cells are incubated with vehicle or BO-264 (1 μM) for 6 hours. After treatment, cell pellets are resuspended in Tris-buffered saline (TBS) buffer containing protease and phosphatase inhibitors. The cell suspension is divided into 6 PCR tubes and heated for 5 minutes to 45, 46, 47, 48, 49 and 50 ℃. Subsequently, cells are lysed by three repeated freeze-thaw cycles with liquid nitrogen. Soluble proteins are collected with centrifugation at 20,000 g for 20 minutes at 4 ℃ and analyzed by SDS-PAGE followed by western blot analysis.
Animal Study:

[1]
  • Animal Models

    female nude mice with xenografts of HER2-positive JIMT-1 cell line

  • Dosages

    25 mg/kg

  • Administration

    Oral gavage
