PORCN抑制剂;抑制Wnt加工和分泌;PORCN inhibitor; inhibits Wnt processing and secretion;IWP-2 是Porcn功能钝化剂,IC50为27 nM,是Wnt生成抑制剂。一般描述 IWP-2是一种Wnt信号和分泌抑制剂,无细胞试验中IC50为27 nM,选择性阻断Porcn介导的Wnt棕榈酰化,一般不影响Wnt/β-catenin,且对Wnt刺激的细胞反应没有影响。IWP-2可特定低抑制 CK1δ。IWP-2 是 Wnt 加工和分泌的抑制剂,其 IC50 为 27 nM。IWP-2 靶向膜结合的 O-酰基转移酶 porcupine (Porcn),从而阻止关键的 Wnt 配体棕榈糖基化。IWP-2 还是一种具有 ATP 竞争能力的 CK1δ 抑制剂,对于 M82FCK1δ 的 IC50 为 40 nM。;IWP-2 is an inhibitor of Wnt processing and secretion with IC50 of 27 nM in a cell-free assay, selective blockage of Porcn-mediated Wnt palmitoylation, does not affect Wnt/β-catenin in general and displays no effect against Wnt-stimulated cellular responses.An inhibitor of Wnt productionApplicationIWP-2 has been used to treat the cell lines L-Wnt-3a and L-Wnt-5a, to demonstrate the inhibitory effect of IWP-2. It has also been used as a Wnt signaling inhibitor to treat WT and Gja1Jrt/+ stromal cells to confirm that, theWnt/β-catenin signaling pathway pathway was not involved in the increased marker expression by Gja1Jrt/+ osteoblasts.
