A series of anthranilamide derivatives were designed and synthesized as novel smoothened (SMO) inhibitors based on the SMO inhibitor taladegib (LY2940680), which can also inhibit the SMO-D473H mutant, via a ring-opening strategy. The phthalazine core in LY2940680 was replaced with anthranilamide, which retained the inhibitory activity towards the hedgehog (Hh) signaling pathway as evidenced by a dual
设计并合成了一系列邻氨基苯甲酰胺衍生物,作为基于SMO抑制剂taladegib(LY2940680)的新型平滑(SMO)抑制剂,后者也可以通过开环策略抑制SMO-D473H突变体。LY2940680中的酞嗪核心被蒽环酰胺取代,后者通过双重萤光素酶报告基因检测证实了对刺猬(Hh)信号通路的抑制活性。化合物12a对Hh信号通路表现出最佳的抑制活性,IC50值为34.09 nM,并且对Daoy细胞系的增殖抑制活性(IC50 = 0.48μM)比LY2940680(IC50 = 0.79μM)好。
