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 this compound in concentration-dependent manners, as examined by sphere formation of colon and head and neck cancer stem cells under nonadherent conditions. It inhibits Wnt/β-catenin signaling, but does not interfere with E-cadherin/β-catenin-mediated cell-cell adhesion. This chemical 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].

	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 this compound 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.
