Description

LGK974 is a highly potent, selective and orally bioavailable Porcupine inhibitor (Wnt signaling antagonist) with an IC50 ~0.4 nM. LGK974 potently inhibits Wnt signaling in vitro and in vivo, including reduction of the Wnt-dependent LRP6 phosphorylation and the expression of Wnt target genes, such as AXIN2. LGK974 is potent and efficacious in multiple tumor models at well-tolerated doses in vivo, including murine and rat mechanistic breast cancer models driven by MMTV–Wnt1 and a human head and neck squamouscell carcinoma model (HN30). We also show that head and neck cancer cell lines with loss-of-function mutations in the Notch signaling pathway have a high response rate to LGK974. All LGK974-sensitive pancreatic cancer cell lines carried inactivating mutations of RNF43. Currently LGK974 is in the Phase I study to treat cancers that are driven by the Wnt pathway in a Wnt ligand-dependent manner.LGK974 is a highly potent, selective and orally bioavailable Porcupine inhibitor (Wnt signaling antagonist) with an IC50 ~0.4 nM.

How to use

In Vitro:

LGK974 was suggested to be used at 0.1 μM final concentration in vitro to completely block Wnt protein secretion.

In Vivo:

LGK974 was used to dose mice orally at 0.1-10 mg/kg once or twice per day to achieve good efficacy in xenograft models.
