    Description

    NSC305787 is an inhibitor of ezrin with a Kd of 5.85 μM, inhibits the phosphorylation of ezrin caused by PKCΙ with an IC50 of 8.3 μM, has antitumor activity.

    IC50 & Target

    Kd: 5.85 μM (ezrin)[1]
    IC50: 8.3 μM (ezrin)[1]

    In Vitro

    NSC305787 is an inhibitor of ezrin with a Kd of 5.85 μM, and has antitumor activity. NSC305787 inhibits PKCΙ phosphorylation of Ezrin, Moesin, Radixin, MBP, with IC50s of 8.3, 9.4, 55, 58.9 μM, respectively. NSC305787 binds to PKCΙ with a Kd value of 172.4 μM, and inhibits ezrin T567 phosphorylation primarily via its binding to ezrin and not through inhibition of PKCΙ kinase activity. NSC305787 (1, 10 μM) shows inhibitory activity against ezrin-mediated invasion of K7M2 osteosarcoma (OS) cells. Moreover, NSC305787 (10 μM) reduces cell motility phenotypes in zebrafish and blocks OS metastatic growth in lung organ culture[1].

    In Vivo

    NSC305787 (0.240 mg/kg/day, i.p.) suppresses ezrin-dependent osteosarcoma metastatic growth in mouse lung[1]. NSC305787 (240 μg/kg, i.p.) dramatically inhibits pulmonary metastasis in a transgenic mouse model of osteosarcoma (Osx-Cre+p53fl/flpRBfl/fl) and shows a more favorable pharmacokinetic profile compared with NSC668394 in the mouse model[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: ≥ 0.6 mg/mL (1.35 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.6 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.0 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% (20% SBE-β-CD in Saline)

      Solubility: ≥ 0.6 mg/mL (1.35 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.6 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Cell Assay
    [1]

    Human umbilical vein endothelial cells (HUVECs; 2.5 × 104/well) are seeded in a 96-well plate in endothelial growth media-2. Following formation of a confluent HUVEC monolayer (∼32 h), endothelial growth media-2 is aspirated and a layer of osteosarcoma (OS) cells (1.0 × 104 cells/well) is added to Dulbecco’s modified Eagle medium containing NSC305787. This specific time point is accepted as 0 h of treatment, and invasion is monitored during the subsequent 5 h by measuring changes in resistance at the cell-electrode interphase. The cell index is calculated according to the following formula: cell index = (Rt – R0)/F, where Rt is resistance at time point t, R0 is background resistance (measured with media alone, no cells) and F is frequency at which the measurement is taken (10 kHz)[1].

    Animal Administration
    [2]

    Mice[2]
    The Osx-Cre+p53fl/flpRBfl/fl transgenic mouse model of osteosarcoma is used in the assay. Mice are treated with 240 μg/kg/day NSC305787, 226 μg/kg/day NSC668394, or vehicle (DMSO, 1%) once daily, five times a week by i.p. injection in a volume of 100 μL. At the end of the study, lung and tumor samples are isolated upon necropsy. Half of each sample is flash frozen immediately in liquid nitrogen, and the other half is fixed in 10% formalin for 18-24 h, transferred to 70% ethanol, and stored at room temperature[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.
