LGK-974是特异的PORCN抑制剂,能抑制Wnt信号通路,IC50为0.4 nM。
LGK-974 is a potent and specific PORCN inhibitor, and inhibits Wnt signaling with IC50 of 0.4 nM.Porcupine (PORCN) is a membrane bound O-acyltransferase that mediates palmitoylation of Wnt family proteins. This step is required for secretion and biologic activity of Wnt proteins, which have roles in embryonic development and cancer. LGK 974 greatly reduces Wnt secretion without decreasing its synthesis and without increasing cytotoxicity.

动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
