| 产品描述 | LF3 is a specific inhibitor of canonical Wnt signaling by disrupting the interaction between β-catenin and TCF4 (IC50 < 2 μM) |
| 靶点活性 | β-catenin/TCF4 (Alpha Screen):1.65 μM , β-catenin/TCF4 (ELISA):1.82 μM |
| 体外活性 | LF3在带有外源报告基因的细胞和Wnt活性内源性高的结肠癌细胞中抑制了Wnt/β-catenin信号。同时,LF3还压制了与Wnt信号传导相关的癌细胞特征,包括高细胞运动性、细胞周期进程以及Wnt靶基因的过表达[1]。 |
| 体内活性 | LF3 在小鼠结肠癌异种移植模型中抑制了肿瘤生长,并诱导了分化。LF3 是一种特定的经典 Wnt 信号通路抑制剂,具有抗癌活性[1]。 |
| 动物实验 | Unsorted GFPlow and GFPhigh SW480 cells (1 × 10^4) were subcutaneously injected into the back skin of NOD/SCID mice. Tumor growth was monitored over a period of 45 days. For therapy, LF3 was administered i.v. at 50 mg/kg body weight for three rounds over 5 consecutive days, with 2-day breaks[1]. |
