suggest that the triazole functionality is required for ITZ-mediated inhibition of angiogenesis but that it is not essential for inhibition of Hh signaling. The synthesis and evaluation of stereochemically defined des-triazole ITZ analogues also provides key information as to the optimal configuration around the dioxolane ring of the ITZ scaffold. Finally, the results from our studies suggest that two
伊曲康唑(ITZ)是FDA批准的三唑类抗真菌药。最近的两次药物重新筛选将ITZ视为一种有前途的抗癌
化学疗法,可抑制血管生成和刺猬(Hh)信号通路。我们已经合成并评估了第一代和第二代ITZ类似物的抗Hh和抗血管生成活性,以更全面地探究这些抗癌特性的结构要求。我们的总体结果表明,三唑功能是ITZ介导的血管生成抑制所必需的,但对于抑制Hh信号传导并不是必需的。立体
化学定义的des的合成和评价-三唑ITZ类似物还提供有关ITZ支架二
氧戊环环周围最佳构型的关键信息。最后,我们研究的结果表明,两种不同的细胞作用机制支配了ITZ支架的抗癌特性。
