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 properties. Finally, optimization leads to the identification of compound 19a, a potent Hh signaling pathway inhibitor with superior potency in vitro and satisfactory pharmacokinetic properties in vivo.
通过用吡咯并[2,1-f][1,2,4]三嗪骨架取代我们早期报道的先导化合物1的嘧啶骨架，设计了一系列新型的Hh信号通路抑制剂。从这个新骨架开始，基于对A环、C环和D环的结构修饰进行了构效关系研究。并对几种活性更强的化合物进行了体内研究，以分析它们的药代动力学性质。最后，经过优化得到了化合物19a，它是一种有效的Hh信号通路抑制剂，具有优异的体外活性和令人满意的体内药代动力学性质。
