体外研究
(In Vitro)

When U266 cells are incubated with Nifuroxazide, a significant dose-dependent decrease in STAT3 tyrosine phosphorylation is observed. This inhibition of STAT3 tyrosine phosphorylation is rapid, occurring as early as 1 h after treatment, and is sustained for at least 24 h. Treatment of U266 or INA6 cells with Nifuroxazide for 48 hours result in a dose-dependent loss of cell viability with an EC50 of approximately 4.5 μM in both cell types. Notably, the MM cells lacking constitutive STAT3 activation show little toxicity to Nifuroxazide[1].

体内研究
(In Vivo)

Compared with the vehicle group, treatment with Nifuroxazide could inhibit tumor growth and tumor weight in a dose-dependent manner, with the inhibition rate of tumor volumes being 43.0% and 62.1% at 25 mg/kg and 50 mg/kg, respectively. It is also shown that Nifuroxazide significantly inhibits the proliferation of nuclear Ki-67-positive cells and induces apoptosis cells of cleaved caspase-3-positive cells. Besides, it is found that treatment with Nifuroxazide could inhibit the expression of MMP-2, MMP-9 and p-Stat3 in A375 tumor tissues. What’s more, Nifuroxazide inhibits the infiltration of MDSCs into the lung, which might be associated with suppression of distant colonization of tumor cells in B16-F10 melanoma metastasis model[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: ≥ 2.58 mg/mL (9.37 mM); 悬浊液

    此方案可获得 ≥ 2.58 mg/mL(饱和度未知)的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 25.8 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

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 2.58 mg/mL (9.37 mM); 悬浊液

    此方案可获得 ≥ 2.58 mg/mL(饱和度未知)的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    1 mL 工作液为例,取 100 μL 25.8 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Mice[2]
Mice engrafted subcutaneously with 1×107 A375 cells are randomly divided into groups when tumor volume is around 100 mm3 and are administrated intraperitoneally injected with Nifuroxazide 25 mg/kg, 50 mg/kg or vehicle once daily. The tumor size and body weight are measured every 3 days. C57Bl/6J mice are engrafted by injecting intravenously via the tail vein with 2×105 B16-F10 cells to produce experimental lung metastasis. They are randomly assigned to groups on day 6 and are intraperitoneally injected with Nifuroxazide 50 mg/kg or vehicle once daily. Black dots on lung surface are counted and confirmed as melanoma metastases[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.
