iCRT 14 is a novel potent inhibitor of β-catenin-responsive transcription (CRT), with IC₅₀ of 40.3 nM against Wnt responsive STF16 luciferase.

IC50: 40.3 nM (Wnt responsive STF16 luciferase)^[1]

iCRT14 can interfere with TCF binding to DNA in addition to its ability to influence TCF-β-cat interaction^[1]. iCRT14 (10, 25, 50 μM) effectively inhibits cell proliferation in BT-549 cells in a dose- and time-dependent manner, but still less potent than iCRT3^[2].

Cells are seeded at 20,000 cells/well into 96-well plates. After overnight incubation, cells are treated with DMSO or each Wnt inhibitor (iCRT-3, 75 μM; iCRT-5, 200 μM; iCRT-14, 50 μM; IWP-4, 5 μM and XAV-939, 10 μM) for 48 hours. Cell viability is determined using the Cell Titer-Glo luminescent cell viability assay kit. Luminescence is measured using FLUOstar microplate reader. All treatments are performed in triplicate, and each experiment is repeated three times.
