A novel series of Hh signaling pathway inhibitors were designed by replacing the pyrimidine skeleton of our earlier reported lead compound 1 with pyrrolo[2,1-f][1,2,4]triazine scaffold. Starting from this new scaffold, SAR exploration was investigated based on structural modification on A-ring, C-ring and D-ring. And several much potent compounds were studies in vivo to profile their pharmacokinetic

[1,2,4]三嗪支架取代我们较早报道的先导化合物1的
嘧啶骨架,设计了一系列新的Hh信号通路
抑制剂。从这种新的支架开始,基于对A环,C环和D环的结构修饰,对
SAR勘探进行了研究。并在体内研究了几种功能强大的化合物,以描述其药代动力学特性。最后,优化导致鉴定化合物19a,这是一种有效的Hh信号通路
