Description

Barasertib-HQPA (AZD2811) is a highly selective Aurora B inhibitor with an IC50 of 0.37 nM in a cell-free assay. Barasertib-HQPA (AZD2811) induces growth arrest and apoptosis in cancer cells[1].

IC50 & Target[1]

Aurora B

0.37 nM (IC50)

In Vitro

Barasertib-HQPA (3 μM, 3 hours) significantly decreases expression of the phosphorylated forms of histone H3 in freshly isolated leukemia cells[1].
? Barasertib-hydroxyquinazoline pyrazol anilide (HQPA) is converted rapidly to the active Barasertib-HQPA in plasma[2].
? Barasertib-HQPA treatment induced defective cell survival, polyploidy, and cell death in LNCaP cell line[3].
? Barasertib-HQPA induces a marked anti-propliferative effect accompanied by the appearance of a polyploid population, which in most cases led to apoptosis[4].

Cell Line: AML lines (HL-60, NB4, MOLM13), ALL line (PALL-2), biphenotypic leukemia (MV4-11), acute eosinophilic leukemia (EOL-1), and the blast crisis of chronic myeloid leukemia K562 cells.
Concentration: 0-100 nM. (Barasertib -HQPA)
Incubation Time: 48 h.
Result: IC50 values ranged from 3 nM to 40 nM.

? Barasertib-HQPA (AZD1152, 5 mg/kg) enhances the ability of vincristine or daunorubicin to inhibit the proliferation of human MOLM13 leukemic xenografts[1].
? Barasertib-HQPA (AZD1152, (10-150 mg/kg/d) potently inhibited the growth of human colon, lung, and hematologic tumor xenografts (mean tumor growth inhibition range, 55% to z100%; P < 0.05) in immunodeficient mice[2].

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 (4.93 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 (4.93 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.

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.
