    Description

    BI 2536 is a dual PLK1 and BRD4 inhibitor with IC50s of 0.83 and 25 nM, respectively[1]. BI-2536 suppresses IFNB (encoding IFN-β) gene transcription[4].

    IC50 & Target[1]

    PLK1

    0.83 nM (IC50)

    Plk2/Snk

    3.5 nM (IC50)

    Plk3/Fnk

    9 nM (IC50)

    BRD4

    25 nM (IC50)

    In Vitro

    Exceeding a 100-fold concentration range starting at 10 nM, BI 2536 causes HeLa cells to accumulate with a 4N DNA content, indicative of a cell-cycle block in either G2 phase or mitosis. In addition to HeLa cells, BI 2536 potently inhibits the proliferation of a panel of 32 human cancer cell lines, representing diverse organ derivations (including carcinomas of the breast, colon, lung, pancreas, and prostate, melanomas, and hematopoietic cancers) and varied patterns of tumor suppressor or oncogene mutations (including RB1, TP53, PTEN, andKRAS status). The half-maximal effective concentration (EC50) values in this cell panel ranged 2-25 nM, whereas a concentration of 100 nM of BI 2536 is typically sufficient for inducing a complete mitotic arrest. The proliferation of exponentially growing hTERT-RPE1, human umbilical vein endothelial cells (HUVECs), and normal rat kidney (NRK) cells is blocked at EC50values ranging 12-31 nM, indicating a comparable sensitivity of cycling nontransformed cells to BI 2536[3].

    In Vivo

    BI 2536 (40-50 mg/kg, i.v.) blocks the growth of human cancer xenografts in immunodeficient, nu/nu mice. Consecutive cycles of 40-50 mg/kg BI 2536 given i.v. once or twice per week are found to be highly efficacious in diverse xenograft models, such as the HCT 116 colon cancer with complete tumor suppression with the twice per week schedule (treated versus the control (T/C) value 0.3%) and a T/C value of 16% with once per week treatment; both schedules are well-tolerated, as judged by clinical signs and absence of major body-weight changes[3].

    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: ≥ 3.25 mg/mL (6.23 mM); Clear solution

      This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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.

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 3.25 mg/mL (6.23 mM); Clear solution

      This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Cell Assay
    [3]

    Cell proliferation assays are performed by incubation in the presence of various concentrations of BI 2536 (10 nM-1 μM) for 72 hr, and cell growth is assessed by the measurement of Alamar Blue dye conversion in a fluorescence spectrophotometer. Effective concentrations at which cellular growth is inhibited by 50% (EC50) are extrapolated from the dose-response curve fit[3].

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

    Animal Administration
    [3]

    Mice[3]
    Female BomTac:NMRI-Foxn1nu mice are grafted subcutaneously with HCT 116 colon-carcinoma, NCI-H460, or A549 lung-carcinoma cells by subcutaneous injection, respectively, of 2×106, 1×106, and 1×107 cells into the flank of each mouse. When tumors reached a volume of approximately 50 mm3, animals are pair-matched into treatment and control groups of ten mice each. In regression experiments, treatment is not initiated until the mean tumor volume reached 500 mm3. BI 2536 is injected intravenously into the tail vein at the indicated dose and schedule. The administration volume is 10 mL per kg body weight. Tumor volumes are determined three times a week with a caliper. The results are converted to tumor volume (mm3) by the following formula: length×width2×π/6. The weight of the mice is determined as an indicator of tolerability on the same days. For statistical analysis, the treatment group is compared with the vehicle control group in a one-sided (decreasing) exact Wilcoxon test.

    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.
