ligand (TRAIL) signaling pathway induces apoptosis in cancer cells but not in normal cells. Therefore, this pathway has attracted attention regarding possible clinical treatment of cancer. However, many cancer cells demonstrate TRAIL resistance. To overcome this problem, small molecules that sensitize cancer cells to TRAIL are desired. Heterocyclic derivatives of the natural product, fuligocandin B (2)
肿瘤坏死因子相关的凋亡诱导配体(TRAIL)信号转导通路在癌细胞中诱导凋亡,而在正常细胞中不诱导。因此,该途径引起了关于可能的癌症临床治疗的关注。然而,许多癌细胞表现出对TRAIL的抗性。为了克服这个问题,需要使癌细胞对TRAIL敏感的小分子。合成了具有克服TRAIL抗性活性的天然产物富叶菌素B(2)的杂环衍生物,并对其活性进行了评估。在合成分子中,喹啉衍生物(10克)对TRAIL耐药的胃腺癌细胞具有有效的活性。在对目标蛋白含缬沙星的蛋白进行对接研究后,设计并合成了7'-氨基富丽花菌素B(10m)。化合物10m也显示出良好的克服TRAIL抗性的活性。与不使用TRAIL相比,使用10m的TRAIL在30 µM时的生存力差异为49.7%。该活性优于黄褐菌素B(2)。
