iCRT5 | Beta-catenin inhibitor

iCRT5 (18623-44-4) is a selective CRT (β-catenin-responsive transcription) inhibitor.1  IC50=18 nM for Wnt responsive STF16 luciferase. Acts via interfering with the β-catenin, TCF4 interaction.1 Displays poor inhibition of cell proliferation in triple-negative breast cancer cells.2 Increases the surface expression of MHCII, CD80 and CD86 on unstimulated dendritic cells (DCs) with no detrimental effects on immune-phenotype of stimulated DCs.3 Modulators of Wnt signaling show great promise in animal models of several cancers.4 Cell permeable.
