体外研究
(In Vitro)

C188-9 是一种 Stat3 抑制剂,Kd 为 4.7 nM[1]
C188-9 抑制 AML 细胞系中 Stat3 活化的 IC50 在 4-7 μM 范围内,在原发性 AML 样本中,IC50 在 8-18 μM 范围内。对于细胞凋亡研究,用 C188-9 处理 AML 细胞系和原发性样本 24 小时,然后通过 FACS 分析对膜联蛋白 V 标记细胞的凋亡细胞进行量化。诱导细胞凋亡的 EC50 变化很大,范围从 6 μM 到 50 μM 以上[2]

体内研究
(In Vivo)

在约 13,528 个可识别基因中,37 个基因转录本的水平受到 C188 的影响(17 个基因下调,20 个基因上调,fdr <0.01,倍数变化≥1.5),其中 7 个是已知的 STAT3 基因靶标。相比之下,C188-9 影响的与致癌作用有关的基因数量要多得多(共 384 个,95 个基因下调,289 个基因上调),包括 76 个之前报告的受 STAT3 调控的基因(38 个基因下调,38 个基因上调)。在之前显示受 STAT3 上调的 38 个基因中,24 个(63%)基因在 C188-9 处理后下调,这与预期一致。此外,C188-9 还下调了 10 个基因(fdr <0.01,倍数变化≥1.5),而之前这些基因被 STAT1 上调。因此,在 48 个 (83.3%) 被 C188-9 下调的基因中,有 40 个基因之前被证实受 STAT1 正向调控,其中 16 个基因被证实受 STAT3STAT1 共同调控。该分析提出了这样一种可能性:C188-9 对 HNSCC 肿瘤中基因转录水平的影响是由其对 STAT3STAT1 的影响介导的[3]

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: ≥ 2.08 mg/mL (4.41 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 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。

Cell Assay
[1]

Cell lines are plated at 2 to 5×105 cells/mL in growth medium and treated with increasing doses of inhibitor for 24 hours. CD34+ AML cells are plated at 1 to 2×105 cells/mL in IMDM with 20% FBS and Pen/Strep, and incubated with C188-9 (0.3 to 100 μM) for 48 hours. Cells are then harvested and labeled. The fraction of spontaneous apoptosis is determined from an untreated sample and then subtracted from the drug-treated samples to yield the percentage of apoptosis attributed to drug treatment[1].

Animal Administration
[3]

Mice[3]
UM-SCC-17B cells (1.5×106) are injected into the tongues of athymic, 8-10 week old, male, nude mice. Once tumors are established, mice (20 total; 10/group) are randomized (average tumor vol ~15-20 mm3) to receive 5 times a week, intraperitoneal injections of either DMSO or C188 (50 mg/kg) or C188-9 (100 mg/kg). Tumor volumes are measured twice weekly. Average tumor volumes 6/πx (long dimension) x (short dimension)2)) are calculated and normalized to the volume at first day of treatment and plotted comparison is done by t test (* p<0.05) [3].

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.
