IWP-4 is a small molecule Wnt inhibitor with an IC50 of 25 nM.

IC50 & Target

IC50: 25 nM (Wnt)[1]

In Vitro

IWP-4 is a small molecule Wnt inhibitor with an IC50 of 25 nM. IWP-4 induces the expression of cardiac markers, including cardiac troponin I (CTNI) and cardiac myosin heavy chain bright cells (MYHhi +). IWP-4 also results in the appearance of beating foci (0.44±0.10 SEM beats per second), which is absent in all cultures not receiving IWP-4. Further, flow cytometric analysis shows that there are significantly more MYHlo + cells in IWP-4 treated cultures (P<0.0002) compare with untreated cultures at day 16, being 17.0±1.3 SD% and 5.4±1.4 SD%, respectively. Quantification of NKX2-5 protein expression shows that 63% (481/817) of IWP-4 treated cells display nuclear NKX2-5 expression[1]. Mesenchymal precursor cells (MPCs) treated with IWP-4 show no significant changes in the expression of AXIN2, CTNNB1 and GSK3B as compare to osteogenic medium alone on day 7, but MPCs treated with IWP-4 express elevates levels of DKK1 and GSK3β on day 21. IWP-4 also causes a significant down regulation of SPARC and COL1A1[2].

Cell Assay

hESC cultures are obtained in mTeSR-1 medium and expanded with daily medium exchange until colonies reach the desired level of confluence (~70% to 80%). At this time (marked day 0), mTeSR-1 is replaced with a basal medium comprised of RPMI 1640 medium supplemented with 2% B27 supplement and 1% penicillin/streptomycin. 20 ng/mL BMP-4 and/or 6 ng/mL activin A are added to the basal medium for primitive streak induction, and exchanged daily until day 3. Then, basal media with or without 5 mM IWP-4 is added to the cells and exchanged every 2 days [dimethyl sulfoxide (DMSO) at the same concentration is used as a vehicle control] until day 15, after which basal medium is supplied every 2 days[1].
