  摘要：

  刺猬（Hh）信号通路是一条在胚胎发育过程中调节图案形成、生长和细胞迁移的通路，但在成年后仅限于组织维护和修复。抑制性通路组分的突变失活导致刺猬信号通路的成熟配体无关激活，导致基底细胞癌和髓母细胞瘤等癌症的发生。刺猬信号的配体依赖性激活参与前列腺癌、胰腺癌、乳腺癌和血液癌的发生。因此，抑制异常的刺猬信号代表了一种有前途的新型抗癌疗法。该发明提供了一种抑制刺猬通路信号的化合物I的新分子，并为治疗恶性肿瘤（基底细胞癌、髓母细胞瘤、胶质母细胞瘤、非小细胞肺癌、前列腺癌、胰腺癌、血液癌、间叶细胞癌等）、预防肿瘤再生长、增强放疗和化疗的敏感性以及其他疾病（炎症、纤维化和免疫紊乱）的治疗应用。
