- 产品描述： Foscenvivint (ICG-001)拮抗Wnt/β-catenin/TCF介导的转录，并特异性结合到启动子结合蛋白（CBP)，IC50为3 μM，但不能结合到相关的转录共激活因子p300上。ICG-001 可诱导凋亡
- 靶点： CBP(Cell-free assay):3 μM
- 体外研究： ICG-001 作用于TOPFLASH 时，IC50为3 μM，而对含突变TCF位点的相关报告基因结构, FOPFLASH没有作用效果。使用25μM ICG-001处理SW480 细胞8小时后，降低Survivin和 Cyclin D1 RNA和蛋白的稳定水平，这两者都可通过β-catenin上调。ICG-001 作用于转化细胞而不是正常结肠细胞，选择性诱导凋亡，降低结肠癌细胞生长。ICG-001作用于presenilin-1突变细胞，可表型营救正常神经生长因子(NGF)诱导的神经元分化和神经轴突生长，强调TCF/β-catenin 信号通路在神经轴突生长和神经元分化中的重要性。最新研究显示 5μM ICG-001作用于MCF7细胞，抑制leptin诱导的EMT, 入侵和肿瘤干细胞球形成
- 体内研究： ICG-001 水溶性类似物处理9周，降低42%结肠和小肠息肉的形成，和非甾体类抗炎试剂Sulindac效果类似，Sulindac是一贯治疗这种疾病模型的药物。在整个的处理期间观察不到明显的毒性。类似物按150 mg/kg 剂量静脉注射处理SW620裸鼠肿瘤衰退移植瘤模型，处理19天，显著降低肿瘤体积，没有死亡，体重也没有降低。ICG-001 每天按5 mg/kg剂量处理小鼠，显著抑制beta-catenin信号，且降低 Bleomycin诱导的肺纤维化，同时保护上皮细胞
- 细胞实验： Cell lines: Human colon carcinoma cell lines SW480, SW620, and HCT116, normal colonic epithelial cell line CCD-841Co Concentrations: ~25 μM Incubation Time: 24 hours Method: 1. Prior to starting the assay, prepare the Apo-ONE Caspase-3/7 Reagent, and mix thoroughly. 2. For best results, empirical determination of the optimal cell number, apoptosis induction treatment and incubation period for the cell culture system may be necessary. 3. Use identical cell numbers and volumes for the assay and the negative control samples. 4. Do not mix Apo-ONE Caspase-3/7 Reagent and samples by manual pipetting. Mixing in this manner is unnecessary and may create bubbles that interfere with fluorescence readings or cross-contaminate the samples. Gentle mixing may be performed using a plate shaker. 5. Total incubation time for the assay depends upon the amount of caspase- 3/7 present in the sample. 6. The Apo-ONE Caspase-3/7 Reagent is formulated to mediate cellular lysis and support optimal caspase-3/7 activity. In rare i
- 动物实验： Animal Models: C57BL/6和裸鼠肿瘤模型 Dosages: 20 mg/kg Administration: 腹腔注射
