  Scaffold hopping approach to a new series of smoothened antagonists

  摘要：

  The hedgehog (Hh) signaling pathway is a key regulator during embryonic development, while in adults, it has limited functions such as stem cell maintenance and tissue repair. The aberrant activity of the Hh signaling in adults has been linked to numerous human cancers. Inhibition of Hh signaling therefore represents a promising approach toward novel anticancer therapies. The Smoothened (Smo) receptor mediates Hh signaling. Here we report a new series of Smo antagonists which were obtained by a scaffold hopping strategy. Compounds from this new scaffold demonstrated decent inhibition of Hh pathway signaling. The new scaffold can serve as a starting point for further optimization. (C) 2014 Elsevier Ltd.

  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。

  The hedgehog (Hh) signaling pathway is a pathway which regulates patterning, growth and cell migration during embryonic development, but in adulthood is limited to tissue maintenance and repair. Mutational inactivation of the inhibitory pathway components leads to constitutive ligand-independent activation of the Hh signaling pathway, results in cancers such as basal cell carcinoma and medulloblastoma. Ligand-dependent activation of Hh signaling is involved in prostate cancer, pancreatic cancer, breast cancer and blood cancers. Therefore, inhibition of the aberrant Hh signaling represents a promising approach toward novel anticancer therapy. The invention provides novel molecules of formula I that inhibit hedgehog pathway signaling and provides therapeutic applications for the treatment of malignancies (basal cell carcinoma, medulloblastoma, glioblastoma, non-small cell lung cancer, prostate cancer, pancreatic cancer, blood cancers, mesenchymal cancers, etc.), prevention of tumor regrowth, sensitization of radio-chemo therapies, and other diseases (inflammation, fibrosis and immune disorders).
