The invention provides methods for modulating, e.g., antagonizing, the activity of the Hedgehog signaling pathway, and for treating Hedgehog related disorders such as cancers (e.g., medulloblastoma). In particular, the invention provides methods for inhibiting aberrant growth states resulting from phenotypes such as Ptch loss-of function, Hedgehog gain-of-function, smoothened gain-of-function or Gli gain-of-function by administering to a mammal combinations of Smoothened inhibitors (e.g., a compound of Formula I, Formula II, or Formula III, or any of the compounds listed herein or incorporated by reference) and Gli inhibitors, and/or Phosphatidylinositol 3-kinase (PI3K) inhibitors.
本发明提供了调节(如拮抗)刺猬信号通路活性的方法,以及治疗刺猬相关疾病如癌症(如髓母细胞瘤)的方法。特别是,本发明提供了通过向哺乳动物施用 Smoothened
抑制剂(例如,式 I、式 II 或式 III 的化合物,或本文所列或通过参考文献并入的任何化合物)和 Gli
抑制剂和/或
磷脂酰肌醇 3- 激酶(
PI3K)
抑制剂的组合,抑制表型(如 Ptch 功能缺失、刺猬蛋白功能增益、smoothened 功能增益或 Gli 功能增益)导致的异常生长状态的方法。
