    NSC 74859 (S3I-201) 优先抑制 Stat3 DNA 结合活性,而非抑制 Stat1(IC50 值,Stat3?Stat3,86±33 μM;Stat1?Stat3,160±43 μM;和 Stat1?Stat1,>300 μM),并抑制 Stat5 的结合活性,IC50 为 166±17 μM)。NSC 74859 显著减少活细胞数量,并抑制转化小鼠成纤维细胞 NIH 3T3/v-Src 和乳腺癌细胞系(MDA-MB-231、MDA-MB-435 和 MDA-MB-468)的生长。在 30-100 μM 浓度下,NSC 74859 可在代表性人类乳腺癌细胞系 MDA-MB-435 和 NIH 3T3/v-Src 中诱导显著细胞凋亡,这两种细胞均含有组成性活性 Stat3。乳腺癌 MDA-MB-435 细胞系对 30 μM NSC 74859 更敏感。相比之下,人类乳腺癌 MDA-MB-453 细胞和正常小鼠成纤维细胞 (NIH 3T3) 不含异常 Stat3 活性,对 100 μM 或更低浓度的 NSC 74859 不太敏感。在 300 μM 或更高浓度下,NSC 74859 诱导了与 Stat3 激活状态无关的一般非特异性细胞毒性[1]。 Huh-7 细胞不表达 β2SP 或 TBGFR2,对 STAT3 抑制敏感,NSC 74859 的 IC50 为 100 μM,无论 CD133+ 状态如何。NSC 74859 对 Huh-7 和 SNU-398 细胞的 IC50 为 150 μM,对 SNU-475 细胞的 IC50 为 15 μM,对 SNU-182 细胞的 IC50 为 200 μM。NSC 74859 抑制乳腺癌 MDA-MB-435、MDA-MB-453 和 MDA-MB-231 细胞系,IC50 接近 100 μM[2]

    体内研究
    (In Vivo)

    人类乳腺癌 (MDA-MB-231) 肿瘤小鼠每 2 天或每 3 天静脉注射一次 NSC 74859 (S3I-201) 或载体,持续 2 周,每 2-3 天测量一次肿瘤。与继续生长的对照(载体治疗)肿瘤相比,接受 S3I-201 治疗的小鼠的人类乳腺癌肿瘤表现出强烈的生长抑制。在治疗结束后对接受治疗的小鼠进行持续评估,结果显示肿瘤没有恢复生长,这表明 S3I-201 对肿瘤生长可能具有长期影响[1]。与继续生长的载体治疗的对照肿瘤(n=15)相比,S3I-201 治疗生长激素细胞肿瘤异种移植瘤(n=15)在实验期间显著减弱了肿瘤生长。注射 NSC 74859 后 5 天,NSC 74859 治疗组大鼠的肿瘤体积明显小于未治疗组 (220±16 mm3 vs. 287±16 mm3,P<0.01)。治疗后 15 天,NSC 74859 治疗组大鼠的平均肿瘤体积为对照组的 64% (449±40 mm3 vs. 708±83 mm3,P<0.01)。治疗开始后 15 天处死大鼠并收集肿瘤。 NSC 74859 治疗大鼠的平均肿瘤重量为 78±8 毫克,而对照组大鼠的肿瘤重量为 114±13 毫克(减少 32%;P<0.05)[3]

    Cell Assay
    [1]

    Proliferating cells are treated with or without NSC 74859 (30-100 μM) for up to 48 h. In some cases, cells are first transfected with Stat3C, ST3-NT, or ST3-SH2 domain or mock-transfected for 24 h before treatment with compound for an additional 24-48 h. Cells are then detached and analyzed by annexin V binding and flow cytometry to quantify the percent apoptosis[1].

    Animal Administration
    [1][3]

    Mice[1]
    Six-week-old female athymic nude mice are used. Athymic nude mice are injected in the left flank area s.c. with 5×106 human breast cancer MDA-MB-231 cells in 100 μL of PBS. After 5-10 days, tumors with a diameter of 3 mm are established. Animals are given NSC 74859 i.v. at 5 mg/kg every 2 or 3 days for 2 weeks and monitored every 2 or 3 days. Animals are stratified so that the mean tumor sizes in all treatment are nearly identical. Tumor volume is calculated according to the formula V=0.52×a2×b, where a is the smallest superficial diameter and b is the largest superficial diameter.
    Rats[3]
    Four-week-old female Wistar Furth rats are used. GH3 cells (5×105 cells in 100 μL Matrigel) are subcutaneously injected into the left lumbar area. After 7 days, tumors with a volume of approximately 100 mm3 are established. Rats are given NSC 74859 intravenously at 5 mg/kg every 2 or 3 days for 2 weeks. Tumor size is measured by caliper measurements twice a week, and volume is calculated as follows: volume=(length×width2)/2. Three weeks after cell inoculations, animals are euthanized and excised tumors are weighed. Blood samples are collected 1 day before S3I-201 treatment and again on the day of euthanization. Serum GH and prolactin are assessed by RIA or ELISA, respectively.

    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.
