  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。

  Efficient synthesis of halohydroxypyridines by hydroxydeboronation

  摘要：

  This paper describes a general method for the synthesis of halohydroxypyridines from novel halopyridinylboronic acids and esters recently described by some of us. Halopyridinylboronic acids and esters have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide or meta-chloroperbenzoic acid. These hydroxylations take place regioselectively, without other oxidation (N-oxide formation). (C) 2004 Elsevier Ltd. All rights reserved.

  often arises among tumor cells during treatment with vismodegib. There is clearly an urgent need to explore novel Smo antagonists with improved potency and efficacy. Through a scaffold hopping strategy, we have identified a series of novel tetrahydropyrido[4,3-d]pyrimidine derivatives, which exhibited effective inhibition of Hh signaling. Among them, compound 24 is three times more potent than vismodegib

  髓母细胞瘤是儿童中最普遍的脑肿瘤之一。异常的刺猬（Hh）通路信号被认为与髓母细胞瘤的发生和发展有关。Vismodegib是第一种基于FDA批准的基于抑制异常刺猬信号转导的癌症疗法，其靶点是平滑化（Smo），这是Hh通路的核心G蛋白偶联受体（GPCR）。尽管vismodegib在肿瘤治疗中显示出有希望的治疗效果，但高剂量下的非线性药代动力学（PK）曲线引起了人们的关注，部分原因是水溶性低。许多患者经历不良事件，例如肌肉痉挛和体重减轻。另外，在用vismodegib治疗期间，肿瘤细胞之间经常产生耐药性。显然迫切需要探索具有增强的效力和功效的新型Smo拮抗剂。通过脚手架跳跃策略，我们确定了一系列新型的四氢吡啶并[4,3-d ]嘧啶衍生物，其显示出对Hh信号传导的有效抑制。其中，在NIH3T3-GRE-Luc报告基因检测中，化合物24的效力是vismodegib的三倍。与vismodegib相比，
