体外研究
(In Vitro)

QC6352 is a potent KDM4C inhibitor with an IC50 of 35±8 nM[1]. In a concentration-dependent manner QC6352 dramatically reduces the sphere-forming capacity of BCSC1 and BCSC2. QC6352 blocks proliferation and self-renewal of BCSCs. As shown by western blot analysis the protein levels of (Epidermal growth factor receptor) EGFR are reduced in both BCSC1 and BCSC2 upon treatment with QC6352[2].

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

体内研究
(In Vivo)

QC6352 strongly affects tumor growth and final tumor weight of both BCSC1 and BCSC2 xenografts. Treatment with QC6352 is well tolerated and does not affect body weight of the mice. Results demonstrate that treatment with the KDM4 inhibitor QC6352 blocks BCSC xenograft tumor growth[2].

动物实验:

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: ≥ 1.67 mg/mL (4.31 mM); 澄清溶液

    此方案可获得 ≥ 1.67 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 16.7 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。
  • 方案 二

    Solubility: 1.67 mg/mL (4.31 mM); 悬浊液; 超声助溶

    此方案可获得 1.67 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

Cell Assay
[2]

Cells are detached by Accutase and counted. 1×103 single BCSC1 and BCSC2 cells are seeded as triplicates in 50% Matrigel into individual wells of 24-well ultra-low attachment plates in serum-free MSC medium. After 7 days, spheres over 50 μm diameter are counted for QC6352- and QC6688-treated and control cells and spheres over 20 μm diameter are counted for paclitaxel-treated and control cells[2].

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

Animal Administration
[2]

Mice: When tumors reach a palpable size of 3 mm3, mice are treated with vehicle (control) or QC6352. The inhibitor is administered daily to mice via oral gavage at 10 mg/kg. Control animals receive vehicle only. Animals are monitored twice weekly for weight and tumor growth[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.
