IWP-2
Based on 35 publication(s) in Google Scholar
IWP-2 is an inhibitor of Wnt processing and secretion with an IC50 of 27 nM. IWP-2 targets the membrane-bound O-acyltransferase porcupine (Porcn) and thus preventing a crucial Wnt ligand palmitoylation. IWP-2 is also an ATP-competitive CK1δ inhibitor with an IC50 of 40 nM for the gatekeeper mutant M82FCK1δ.

IWP-2 inhibits the proliferation of the investigated cell lines within the single digit μM range. IWP-2 inhibits cell proliferation in A818-6, MiaPaCa2, Panc-1, Panc-89, HT29, HEK293, SW620 and Capan cell with EC50s of 8.96 μM, 1.90 μM, 2.33 μM, 3.86 μM, 4.67 μM, 2.76 μM, 1.90 μM and 2.05 μM, respectively[2].
Panc-1 cells are either untreated or treated with 2.33 μM IWP-2 for 48 h. In IWP-2 treated cells, the CK1δ kinase peak activity is reduced to approximately 66% residual activity compared to the activity in untreated cells, respectively. IWP-2 reduces the activity of CK1δ in Panc1 cells[2].

Protocol
The human RCC cell lines 786O and Caki-2 (5×103) are seeded into 96-well plates. Cell viability is estimated by MST assay after Caki-2 acells are incubated with ncreasing concentrations of LEF together with 20 μM IWP-2 for 48 h.After treatment, 10 μL MTS is added into each well for 2 h incubation. The absorbance is measured using a model ELX800 Micro Plate Reader at 490 nm. For colony formation assay, Caki-2 cells are trypsinized to single cell suspensions and seeded into fresh 6-well plates at 1000 cells/well. Then cells are incubated with LEF at depicted concentrations for 7 days. Colonies are fixed with absolute methanol for 15 min and then stained with 0.1% crystal violet for 20 min. After washing with PBS three times, the colonies with a diameter over 2 mm are visualized by a digital camera[2].
