Anthraquinones and their analogues, in particular heteroarene-fused anthracendiones, are prospective scaffolds for new compounds with improved antitumor characteristics. We herein report the use of a ‘scaffold hopping’ approach for the replacement of the core structure in the previously discovered hit compound naphtho[2,3-f]indole-5,10-dione 2 with an alternative anthra[2,3-b]furan-5,10-dione scaffold
蒽醌及其类似物,特别是杂亚芳基融合的蒽二酮,是具有改善的抗肿瘤特性的新化合物的预期支架。我们在此报告“脚手架跳跃”方法用于替换以前发现的命中化合物萘[2,3 - f ]吲哚-5,10-二酮2和另一种蒽[2,3- ]的核心结构的替换。b ]呋喃-5,10-二酮支架。在13种新合成的衍生物中,大多数4,11-二羟基-2-甲基-5,10-二氧杂蒽[2,3 - b ]呋喃-3-羧酰胺对一组野生型和耐药性肿瘤表现出很高的抗增殖能力细胞系,其性质优于参考药物阿霉素或萘并铅[2,3- f] indole-5,10-dione 2。在低微摩尔浓度下,(R)-3-氨基吡咯烷3c及其立体异构体(S)-3-氨基吡咯烷3d的选定衍生物引起凋亡细胞死亡,随后被阻滞在G2 / M期。细胞内靶标的研究表明3c和3d与双链DNA形成了稳定的嵌入复合物,这是通过光谱分析和分子对接确定的。3c和3d都通过不同于常规DNA-酶
