    Description

    Adavosertib (AZD-1775; MK-1775) is a potent Wee1 inhibitor with an IC50 of 5.2 nM.

    IC50 & Target

    IC50: 5.2 nM (Wee1)
    In Vitro

    Adavosertib (MK-1775) enhances the cytotoxic effects of 5-FU in p53-deficient human colon cancer cells. Adavosertib (MK-1775) inhibits CDC2 Y15 phosphorylation in cells, abrogates DNA damaged checkpoints induced by 5-FU treatment, and causes premature entry of mitosis determined by induction of Histone H3 phosphorylation[1].
    Adavosertib (MK-1775) abrogates the radiation-induced G2 block in p53-defective cells but not in p53 wild-type lines[2].
    The combination of NSC 613327 with Adavosertib (MK-1775) produces robust anti-tumor activity and remarkably enhances tumor regression response (4.01 fold) compared to NSC 613327 treatment in p53-deficient tumors[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:  5% DMSO    40% PEG300    5% Tween-80    50% Saline

      Solubility: ≥ 2.87 mg/mL (5.73 mM); Clear solution

    • Protocol 2

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (4.16 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    Cell Assay
    [2]

    Total protein is extracted from the cell pellet using a lysis solution containing 50 mM HEPES (pH 7.9), 0.4 mol/L NaCl, and 1 mM EDTA and fortified with 10 µL/mL phosphatase inhibitor cocktail 1, 10 µL/mL phosphatase inhibitor cocktail 2, 10 µL/mL protease inhibitor, and 1% NP-40. Protein concentration of the lysates is determined by the Bio-Rad protein assay. Equal amounts of protein are separated by 12% SDS-PAGE and transferred to an Immobilon membrane. Nonspecific binding sites on the membrane are blocked in 5% nonfat dry milk in Tris (20 mM)-buffered saline (150 mM, pH 7.4) with 0.1% Tween (TBS-T). Protein signals are detected by incubating the membrane in primary antibody in 5% nonfat dry milk overnight at 4°C, followed by a 45-min incubation in the appropriate peroxidase-conjugated secondary antibody. The membrane is then developed by enhanced chemiluminescence with ECL plus Western Blotting Detection Reagents on a Typhoon 9400 scanner.

    Animal Administration
    [2]

    Tumor xenografts are produced in the leg by im inoculation of 1×106 Calu-6 cells in 10 µL. Irradiation and Adavosertib (MK-1775) treatment are started when tumors reach 8 mm diameter and continue for 5 days. Gamma-rays are delivered locally to the tumor-bearing legs of unanesthetized mice using a small-animal irradiator consisting of two parallel-opposed 137Cs sources, at a dose rate of 5 Gy/min. Tumors are irradiated twice daily separated by 6 h. Adavosertib (MK-1775) is given by gavage in 0.1 mL volumes 1 h before and 2 h after the first daily radiation dose.

    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.
