Technical Data

Formula

C20H24N4O2S2
Molecular Weight 416.56 CAS No. 664969-54-4
Solubility (25°C)* In vitro DMSO 83 mg/mL (199.25 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.15mg/ml Taking the 1 mL working solution as an example, add 50 μL 83 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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 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].
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].

Protocol (from reference)

Cell Assay:[1]
  • 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.
Animal Study:[1]
  • Animal Models

    NOD/SCID mice

  • Dosages

    50 mg/kg

  • Administration

    i.v.
