Porcn Inhibitor III, IWP-L6 (IWPL6, Wnt Pathway Inhibitor XIX)
Description
Purity ~99% (HPLC). A cell-permeable pyridinyl-phenylacetamide that is reported to be 60-times more potent than IWP-2 in suppressing autonomous Wnt signaling in murine L-Wnt-STF fibroblasts (IC50 = 0.5nM) and 100-times more potent in blocking branching morphogenesis in cultured murine embryonic kidney (complete blockage at 50nM). Also shown to be at least twice as potent as TNKS inhibitor IWR-1 in preventing the regeneration of severed zebrafish tailfin and in inhibiting zebrafish embryo prosterior axis formation (Effective conc = 5uM). Its susceptibility to metabolization by serum carboxylesterase limits its in vivo use in rats and mice. Solubility: DMSO Primary Target: Porcupine
