In Vitro

GW843682X (compound 1) is effective on inhibition of growth of tumor cells, with IC50s of 0.41, 0.57, 0.11, 0.38, and 0.70 μM for A549, BT474, HeLa, H460 and HCT116 cell lines. GW843682X dose-dependently inhibits PLK1 phosphorylation of Ser15-p53, with an IC50 of 0.14 μM. GW843682X (3 μM) causes a strong G2-M arres in HDF cells and H460 cells after treatment for 24, 48, and 72 h. GW843682X (5 μM) leads to apoptosis in H460 cells instead of HDF cells[1]. GW843682X inhibits proliferation of U937 cells with an EC50 of 120 nM. GW843682X (500 nM) in combination with 5 µM VP-16 suppresses 50% of entry into mitosis in U937 cells[2]. GW843682X (0.06-1 μM) has inhibitory activities against proliferation of acute leukemia cells, and potentiates the anti-proliferative activity of vincristine. Moreover, GW843682X (0.1-1 μM) induces apoptosis of leukemia cells in a dose- and time-dependent manner. GW843682X (0.5-1 μM) dephosphorylates Bcl-xl in leukemia cells[3].

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 (5.24 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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 (5.24 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.

Kinase Assay
[1]

PLK1 and PLK3 proteins are prepared from baculovirus-infected Trichoplusia ni cells. Enzyme activity for PLK1 and PLK3 is determined as follows. All measurements are obtained under conditions where signal production increased linearly with time and enzyme. Test compounds are added to white 384-well assay plates (0.1 μL for 10 μL and some 20 μL assays, 1 μL for some 20 μL assays) at variable known concentrations in 100% DMSO. DMSO (1-5% final) and EDTA (65 mM) are used as controls. Reaction Mix containes the following components at 22°C: 25 mM HEPES (pH 7.2); 15 mM MgCl2; 1 μM ATP; 0.05 μCi/well [γ-33P]ATP (10 Ci/mmol); 1 μM substrate peptide (Biotin-Ahx-SFNDTLDFD); 0.15 mg/mL bovine serum albumin; 1 mM DTT; and 2 nM PLK1 kinase domain or 5 nM full-length PLK3. Reaction Mix (10 or 20 μL) is quickly added to each well immediately following addition of enzyme via automated liquid handlers and incubated for 1 to 1.5 h at 22°C. The 20 μL enzymatic reactions are stopped with 50 μL of stop mix [50 mM EDTA, 4.0 mg/mL streptavidin SPA beads in Dulbecco's PBS (without Mg2+ and Ca2+), 50 μM ATP] per well. The 10 μL reactions are stopped with 10 μL of stop mix [50 mM EDTA, 3.0 mg/mL streptavidin-coupled SPA Imaging Beadsin Dulbecco's PBS (without Mg2+ and Ca2+), 50 μM ATP] per well. Plates are sealed, spun at 500 × g for 1 min or settled overnight, and counted in Packard TopCount for 30 s/well or imaged with a Viewlux imager. Signal above background (EDTA controls) is converted to percent inhibition relative to that obtained in control (DMSO-only) wells[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay
[1]

Assays are carried out and data analyzed. In these assays, H460 cells are plated at a density of 2,000 per well, HDF cells are plated at 5,000 per well, and the drug-resistant cell line MES-SA/DX5 and its sensitive parent line MES-SA are plated at 7,000 and 6,000 per well, respectively, in a 96-well plate. These densities allowed vehicle controls to grow logarithmically during the course of the 3-day assay. All cells are exposed to 3-fold dilutions of the compound (30-0.00152 μM) in low-glucose DMEM containing 5% FBS, 50 μg/mL gentamicin, and 0.3% (v/v) DMSO (HDF cells); RPMI 1640 containing 5% FBS, 50 μg/mL gentamicin, and 0.3% (v/v) DMSO (H460); or McCoy's 5A containing 5% FBS, 50 μg/mL gentamicin, and 0.3% (v/v) DMSO (MES-SA and MES-SA/DX5)[1].
