C59

A cell-permeable pyridinylphenyl-acetamide that is much more potent than IWP-2 (Cat. No. 681671) in inhibiting MBOAT (membrane-bound O-acyltranferase) family member Porcn- (Porcupine) mediated Wnt palmitoylation (IC50 = 74 pM in STF reporter assays using Wnt3a-transfected HEK293 cells). Shown to be effective against Porcn of murine (mPorcn-A, B, C, D) and human (hPorcn-B), but not xenopus (xPorcn-A), species and potently inhibit the processing of both canonical (1, 2, 3a, 6, 7b, 8a, 9a, 9b, 10) and non-canonical (4, 5a, 11, 16) Wnt subtypes. C59 is demonstrated to be orally active and effectively suppress MMTV-WNT1 tumor expansion in mice (5 mg/kg & 10 mg/kg p.o.) in vivo.

Porcn Inhibitor II, C59 has been used as a Wnt inhibitor in the differentiation protocol of hiPSCs to cardiomyocytes.
