Carbohydrate moieties were strategically transported from the indolocarbazole topoisomerase I (Top1) inhibitor class to the indenoisoquinoline system in search of structurally novel and potent Top1 inhibitors. The syntheses and biological evaluation of 20 new indenoisoquinolines glycosylated with linear and cyclic sugar moieties are reported. Aromatic ring substitution with 2,3-dimethoxy-8,9-methylenedioxy
碳水化合物部分被策略性地从吲哚并咔唑拓扑异构酶 I (Top1) 抑制剂类转移到茚并异喹啉系统,以寻找结构新颖且有效的 Top1 抑制剂。报告了 20 种新型茚并异喹啉糖基化的线性和环状糖基的合成和生物学评价。2,3-二甲氧基-8,9-亚甲二氧基或3-硝基的芳环取代对抗增殖和Top1抑制活性有很强的影响。虽然碳水化合物侧链的长度与抗增殖活性明显相关,但立体化学和生物活性之间的关系不太清楚。12 种新茚并异喹啉表现出等于或优于喜树碱的 Top1 抑制活性。
