生物活性    
LGK974 (WNT974) is an orally bioavailable and specific Porcupine (PORCN) inhibitor with an IC50 of 0.1 nM[1].

IC50 & Target    
Porcupine[1]

体外研究
(In Vitro)    
LGK974 effectively displaces [3H]-GNF-1331 with an IC50 of 1 nM in the PORCN radioligand binding assay. LGK974 potently reduces Wnt-dependent AXIN2 mRNA levels in HN30 cells with an IC50 of 0.3 nM

体内研究
(In Vivo)    
LGK974, a drug that targets Porcupine, a Wnt-specific acyltransferase. LGK974 potently inhibits Wnt signaling, has strong efficacy in rodent tumor models, and is well-tolerated. Toxicology studies are performed on nontumor bearing rats at 3 and 20 mg/kg. At the efficacious dose of 3 mg/kg per day for 14 d, LGK974 is well-tolerated without abnormal histopathological findings in Wnt-dependent tissues, including the intestine, stomach, and skin. When rats are administrated a very high dose of 20 mg/kg per day for 14 d, loss of intestinal epithelium is observed, consistent with the concept that Wnt is required for intestinal tissue homeostasis
