    生物活性

    NSC305787 hydrochloride 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]

    体外研究
    (In Vitro)

    NSC305787 hydrochloride 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].

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

    体内研究
    (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].

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
    ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

    • 方案 一

      请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 1.25 mg/mL (2.59 mM); 澄清溶液

      此方案可获得 ≥ 1.25 mg/mL(饱和度未知)的澄清溶液。

      1 mL 工作液为例,取 100 μL 12.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

      生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。

    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].

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

    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.
