LF3 is an antagonist of the β-Catenin/TCF4 interaction with antitumor activity; has an IC50 of 1.65 μM.

IC50 & Target

IC50: 1.65 μM (β-Catenin/TCF4, AlphaScreen), 1.82 μM (β-Catenin/TCF4, ELISA)[1]

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[1].

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[1].

Cell Assay

LF3 is dissolved in DMSO to a concentration of 50 mM and diluted with culture medium. Two colon cancer cell lines (HCT116 and HT29) and a breast cancer cell line (MCF7) are treated with LF3 (0, 30, 60 μM) for 24 hours and labeled with BrdUrd for 4 to 5 hours to detect proliferating cells[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration

Mice: Unsorted GFPlow and GFPhigh SW480 cells are subcutaneously injected into the back skin of NOD/SCID mice. Tumor growth is monitored over a period of 45 days. For therapy, LF3 is administered i.v. at 50 mg/kg body weight for three rounds over 5 consecutive days, with 2-day breaks[1].
