Biological Activity

Description LF3 is a specific inhibitor of canonical Wnt signaling by disrupting the interaction between β-catenin and TCF4 with an IC50 less than 2 μM.
Targets
β-catenin/Tcf4 [1]
(Cell-free assay)
1.65 μM
In vitro
In vitro LF3 does not cause cell death or interfere with cadherin-mediated cell-cell adhesion. The self-renewal capacity of cancer stem cells is blocked by LF3 in concentration-dependent manners, as examined by sphere formation of colon and head and neck cancer stem cells under nonadherent conditions. LF3 inhibits Wnt/β-catenin signaling, but does not interfere with E-cadherin/β-catenin-mediated cell-cell adhesion. LF3 blocks the expression of a series of Wnt target genes in Wnt-addicted colon cancer cells. It inhibits proliferation of Wnt-addicted colon cancer cells through induction of cell-cycle arrest and also inhibits self-renewal capacity of CSCs[1].
Cell Research Cell lines The cell lines HCT116, HCT15, HT29, SW480, SW620, LS174T, SW48, MCF7, HeLa, HEK293, and MDCK 
Concentrations 3.3-60 μmol/L
Incubation Time 24 h
Method β-catenin is immunoprecipitated from protein extracts of the cells that are incubated with LF3 at increasing concentrations, and reduced TCF4 and LEF1 bound to β-catenin are shown by Western blotting.
In Vivo
In vivo LF3 reduces tumor growth and induces differentiation in a mouse xenograft model of colon cancer while exhibiting no significant toxicity for mice and does not disturb the normal histology of the gut of mice[1].
Animal Research Animal Models NOD/SCID mice
Dosages 50 mg/kg
Administration i.v.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
