A series of novel hedgehog signaling pathway inhibitors have been designed by structural modification based on the former reported scaffold of 4-(2-pyrimidinylamino)benzamide. The SAR for this series was described and many derivatives showed potent inhibitory activity. Among these compounds, compounds 12af and 12bf were identified to have high potency and optimal PK profiles. Although both of compounds
基于以前报道的4-(2-嘧啶基氨基)苯甲酰胺的支架,通过结构修饰设计了一系列新颖的刺猬信号途径抑制剂。描述了该系列的SAR,许多衍生物显示出有效的抑制活性。在这些化合物中,化合物12af和12bf被确定具有高效力和最佳PK分布。尽管化合物12af和12bf在LS-174T裸鼠模型中均未显示出强大的抗肿瘤功效,但由于它们对Hh信号通路的强大效力和出色的PK特性,它们有望成为Hh信号抑制剂的候选者,值得在其他Hh信号手术中进一步评估肿瘤模型。
