產(chǎn)品活性：LF3是β-Catenin/TCF4相互作用的拮抗劑，具有抗腫瘤活性。IC50值為1.65 μM。

研究領(lǐng)域：Stem Cell/Wnt

作用靶點(diǎn)：β-catenin

In Vitro: LF3 inhibits Wnt/β-catenin signals in cells with exogenous reporters and in colon cancer cells with endogenously high Wnt activity. LF3 also suppresses features of cancer cells related to Wnt signaling, including high cell motility, cell-cycle progression, and the overexpression of Wnt target genes. However, LF3 does not cause cell death or interfere with cadherin-mediated cell-cell adhesion. Remarkably, the self-renewal capacity of cancer stem cells is blocked by LF3 in concentration-dependent manners.

In Vivo: LF3 reduces tumor growth and induces differentiation in a mouse xenograft model of colon cancer. Tumor growth is significantly reduced when mice with GFPhigh cells are treated with LF3 at 50 mg/kg. LF3 treatment does not disturb the normal histology of the gut of mice.
