    Description

    TAK-733 is a potent and selective MEK allosteric site inhibitor with an IC50 of 3.2 nM.

    IC50 & Target[1]

    MEK

    3.2 nM (IC50)

    In Vitro

    TAK-733 exhibits potent enzymatic and cell activity with an IC50 of 3.2 nM against constitutively active MEK enzyme and an EC50 of 1.9 nM against ERK phosphorylation in cells. TAK-733 does not inhibit any other kinases, receptors or ion channels that are tested with inhibitor concentrations up to 10 μM. TAK-733 is found to bind plasma protein moderately (ca. 97% for human and 96% for mouse), and exhibits high permeability and high microsomal stability across species. It does not inhibit P450s up to 30 μM[1]. TAK-733 demonstrates broad activity in most melanoma cell lines with relative resistance observed at IC50 >0.1 μM in vitro. Thirty-four melanoma cell lines are exposed in vitro to increasing concentrations of TAK-733 for 72 hours. Of the 34 cell lines, 27 are BRAFV600E mutant and 7 are wild-type. SRB proliferation assays are performed and the resulting IC50 concentrations allowed stratification of cell lines into three categories: relatively resistant, intermediate, and highly sensitive. Relatively resistant and highly sensitive lines are assigned based on an IC50 that differ by at least 10 fold[2].

    In Vivo

    The pharmacokinetics of TAK-733 is evaluated in nude mouse, rat, dog and monkey. Low clearance and high oral bioavailability are observed in all species. TAK-733 demonstrates broad antitumor activity in mouse xenograft models of human cancer including models of melanoma, colorectal, NSCLC, pancreatic and breast cancer[1]. Daily oral administration of 1, 3, 10, and 30 mg/kg of TAK-733 for 14 days (Days 10 to 23) results in tumor growth delay in the A375 cell-implanted mice (5/group). TAK-733 (35, 70, 100, and 160 mg/kg) also significantly inhibits tumor growth on an intermittent dosing schedule of 3 days per week for 2 weeks (Days 10, 13, 15, 17, 20, and 22). Three partial regressions (PR), a 60% response rate, are observed in mice administered with 30 mg/kg of TAK-733 daily and in mice administered with 160 mg/kg of TAK-733 intermittently. Responses, CR (complete regression) and partial regressions (PR) are also observed in mice administered with 70, 100, and 160 mg/kg of TAK-733 intermittently. The tumor regression rate is more pronounced with the intermittent administration regimen; the greatest reduction in tumor volume is observed at 160 mg/kg (57.29%), versus a maximum reduction of 46.97% at 30 mg/kg once daily. By the last day of administration, tumor growth is significantly (p<0.05 for %T/C, Student's t-test) inhibited in mice administered 3, 10, and 30 mg/kg once daily or 35, 70, 100, and 160 mg/kg intermittently[2].

    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    90% Corn Oil

      Solubility: ≥ 2.5 mg/mL (4.96 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.

    Cell Assay
    [2]

    The cutaneous melanoma cell lines in logarithmic growth phase are transferred to 96 well flat bottom plates with lids. One hundred μL cell suspensions containing 2000-3000 viable cells are plated into each well and incubated overnight prior to exposure with increasing concentrations of TAK-733 (10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 nM) for 72 hours. Post drug administration, media is removed and cells are fixed with cold 10% trichloroacetic acid for 30 min. at 4°C. Cells are then washed with water and stained with 0.4% SRB for 30 min at room temperature, washed again with 1% acetic acid, followed by stain solubilization with 10 mM tris at room temperature. The absorbance at 565 nm is measured on a plate reader. Cell proliferation curves are derived from the raw absorbance (OD) data. Statistical analyses and graphical representation of data are using GraphPad Prism version 5.00[2].

    Animal Administration
    [2]

    Mice[2]
    Five to six-week-old female athymic nude mice are used. A375 human melanoma xenograft tumors are generated by harvesting cells from mid-log phase cultures using Trypsin-EDTA. Approximately 5×106 cells suspended in Hanks’ balanced salt solution (HBSS) are injected sc into the right flank of 6-8-week-old mice. Oral administration of TAK-733 (1 mg/kg or 10 mg/kg) is initiated when tumors in all mice in each experiment range in size from 100 to 200 mm3 for antitumor efficacy studies and from 300 to 500 mm3 for pharmacodynamic (PD) studies[2].

    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.
