Product Introduction

Bioactivity

名稱	S3I-201
描述	S3I-201 (S3I-201) is a selective Stat3 inhibitor (IC50: 86±33 μM) and low effect towards STAT1/5.
細胞實驗	Proliferating cells were treated with or without S3I-201 for up to 48 h. In some cases, cells were 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 were then detached and analyzed by annexin V binding according to the manufacturer's protocol and flow cytometry to quantify the percent apoptosis [1].
激酶實驗	Briefly, 100 ml of biotinyl-e-Ac-EPQpYEEIEL-OH (in 50 mM Tris/150 mM NaCl, pH 7.5) was added to each well of streptavidin-coated 96-well microtiter plates and incubated with shaking at 4°C overnight. Then plates were rinsed with PBS/Tween 20 and then two times with 200 ml of BSA-T-PBS (0.2% BSA/0.1% Tween 20/PBS). Then 50 ml of Lck-SH2-GST fusion protein (6.4 ng/ml in BSA-T-PBS) was added to each well of the 96-well plate in the presence and absence of 50 ml of S3I-201 (for 30 and 100 mM final concentrations), and the plate was shaken at room temperature for 4 h. After solutions were removed, each well was rinsed four times with BSA-T-PBS (200 ml), and 100 ml of polyclonal rabbit anti-GST antibody (100 ng/ml in BSA-T-PBS) was added to each well and incubated at 4°C overnight. After washing with BSA-T-PBS, 100 ml of 200 ng/ml BSA-T-PBS horseradish peroxidase-conjugated mouse anti-rabbit antibody was added to each well and incubated for 45 min at room temperature. After four washing steps with BSA-T-PBS and three washing steps with PBS-T, 100 ml of peroxidase substrate was added to each well and incubated for 5-15 min. The peroxidase reaction was stopped by adding 100 ml of 1 M sulfuric acid solution, and absorbance was read at 450 nm with an ELISA plate reader [1].
動物實驗	Six-week-old female athymic nude mice were purchased from Harlan and maintained in the institutional animal facilities approved by the American Association for Accreditation of Laboratory Animal Care. Athymic nude mice were injected in the left flank area s.c. with 5 × 10^6 human breast cancer MDA-MB-231 cells in 100 μl of PBS. After 5–10 days, tumors with a diameter of 3 mm were established. Animals were given S3I-201 i.v. at 5 mg/kg every 2 or 3 days for 2 weeks and monitored every 2 or 3 days. Animals were stratified so that the mean tumor sizes in all treatment were nearly identical. Tumor volume was calculated according to the formula V = 0.52 × a2× b, where a is the smallest superficial diameter and b is the largest superficial diameter [1].
體外活性	S3I-201抑制Stat3和Stat3復合體的形成以及Stat3的DNA結合和轉錄活性。此外，S3I-201主要在含有持續(xù)活化Stat3的腫瘤細胞中抑制生長并誘導凋亡。構成性二聚和活性Stat3C以及Stat3 SH2結構域可使腫瘤細胞免受S3I-201引起的凋亡[1]。在p53(null)CD45.1小鼠的CD4 T細胞中，先用不同濃度的S3I-201預處理，可以在添加IL-6后最早15分鐘抑制STAT3的磷酸化，呈劑量依賴性。根據STAT3磷酸化抑制水平，確定此抑制劑的IC50為38μM [2]。雖然這些細胞系對單獨使用S3I-201（S3I-201）不敏感，但S3I-201增強了所有三個細胞系（HepG2、SK-HEP1和Huh-7細胞）對cetuximab的抗增殖效果[3]。
體內活性	與對照組瘤體相比，接受S3I-201治療的小鼠中的人類乳腺癌瘤顯示出強烈的生長抑制作用。與對照組瘤體相比，S3I-201處理的小鼠殘留腫瘤組織中Stat3 DNA結合活性受到強烈抑制。使用PBS處理的同齡p53nullCD45.1小鼠作為對照組，對8至10周齡的p53nullCD45.1小鼠每周3次以5 mg/kg劑量治療S31-201。與PBS處理的小鼠相比，S31-201處理的小鼠脾臟中的STAT3磷酸化顯著降低。S3I-201減輕了大鼠異種移植模型中的生長激素分泌和腺垂體瘤生長。
