产品描述 Stattic 是第一个非肽类STAT3小分子抑制剂，有效抑制STAT3激活和核易位，IC50为5.1 μM，其作用于STAT3的选择性远高于STAT1。Stattic 可诱导凋亡。
特性 Stattic是第一个非肽类小分子，抑制STAT3 SH2结构域的功能，无论在体外STAT3磷酸化状态。

体外研究活性

Stattic抑制gp130受体衍生的含磷酸化酪氨酸的肽结合到STAT3 SH2结构域，这种作用存在强烈的温度依赖性。Stattic对酪氨酸磷酸化的肽结合到酪氨酸激酶Lck的SH2结构域只有很微弱的作用效果。Stattic不抑制其他两个二聚体转录因子(c-Myc/Max 和 Jun/Jun)的二聚化。Stattic抑制荧光素标记的磷酸化肽段结合到STAT1和STAT5b的SH2域。Stattic浓度为10 μM，选择性抑制DNA与STAT3二聚体结合。Stattic抑制STAT3在Tyr705位点磷酸化，而对STAT1在Tyr701(HepG2细胞)位点磷酸化或 JAK1, JAK2, 和c-Src(MDA-MB-231和MDA-MB-235S细胞)磷酸化几乎没有抑制效果。Stattic增加STAT3依赖性的乳腺癌细胞系的凋亡率。[1]
激酶实验 高通量筛选和荧光偏振检测
在约30°C下进行筛选。通过实验化合物与STAT1, STAT5, 和 Lck 的SH2结构域结合的类似实验验证筛选的特异性。所有FP实验的Buffer组分的终浓度为10 mM HEPES(pH 7.5),1 mM EDTA,0.1% Nonidet P-40,50 mM NaCl,和10% DMSO。二硫苏糖醇的存在对抑制活性是必不可少的。肽序列为:STAT3,5-carboxyfluorescein-GY(PO3H2)LPQTV-NH2; STAT1, 5-carboxyfluorescein-GY(PO3H2)DKPHVL;STAT5, 5-carboxyfluorescein-GY(PO3H2)LVLDKW; 和 Lck, 5-carboxyfluorescein-GY(PO3H2)EEIP。在 30°C下进行特异性分析, 使用150 nM蛋白(STAT1,STAT3,和STAT5)。在37°C下进行分析，使用370 nM 蛋白(STAT3)或100 nM蛋白 (Lck)。蛋白与实验化合物在Eppendorf管中在指定温度环境下温育60分钟，然后加入相应的5-carboxyfluorescein标记的肽（终浓度为10 nM）。混合物至少平衡30分钟，然后在室温下测量。实验化合物在20×stock在DMSO中稀释到指定浓度。使用 SigmaPlot绘制结合曲线和抑制曲线。独立实验中，所有竞争曲线都需重复三次。
