A number of indenoisoquinolines were prepared and evaluated for cytotoxicity in human cancer cell cultures and for activity versus topoisomerase I. The two most cytotoxic indenoisoquinolines proved to be cis-6-ethyl-5,6,12,13-tetrahydro-2,3-dimethoxy-8,9(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline and cis-6-allyl-5,6,12,13-tetrahydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-(11H)indeno[1,2-c]isoquinoline. Two of the most potent topoisomerase I inhibitors were 6-(3-carboxy-1-propyl)-5,6-dihydro-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (26) and 6-ethyl-2,3-dimethoxy-8,9-(methylenedioxy)-11H-indeno[1,2-c]isoquinolinium chloride (27). Two additional potent topoisomerase I inhibitors, 6-allyl-5,6-dihydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (13c) and 5,6-dihydro-6-(4-hydoxybut-1-yl)-2,3-dimethoxy-8,9-methylenedioxy-5,11 dioxo-(11H)-indeno[1,2-c]isoquinoline (19a), did not unwind DNA and did not affect topoisomerase II.
已完成。已准备和评估了多种吲哚异喹啉类化合物在人类癌细胞培养物中的细胞毒性和对拓扑异构酶I的活性。其中两种最具细胞毒性的吲哚异喹啉被证明是顺式-6-乙基-5,6,12,13-四氢-2,3-二甲氧基-8,9-(亚甲二氧基)-5,11-二氧基-11H-吲哚[1,2-c]异喹啉和顺式-6-烯丙基-5,6,12,13-四氢-2,3-二甲氧基-8,9-(亚甲二氧基)-5,11-二氧基-(11H)吲哚[1,2-c]异喹啉。其中两种最有效的拓扑异构酶I抑制剂分别是6-(3-羧基-1-丙基)-5,6-二氢-5,11-二氧基-11H-吲哚[1,2-c]异喹啉 (26) 和6-乙基-2,3-二甲氧基-8,9-(亚甲二氧基)-11H-吲哚[1,2-c]异喹啉盐酸盐 (27)。另外两种强效的拓扑异构酶I抑制剂,6-烯丙基-5,6-二氢-2,3-二甲氧基-8,9-(亚甲二氧基)-5,11-二氧基-11H-吲哚[1,2-c]异喹啉 (13c) 和 5,6-二氢-6-(4-羟基丁-1-基)-2,3-二甲氧基-8,9-亚甲二氧基-5,11-二氧基-(11H)-吲哚[1,2-c]异喹啉 (19a),未对DNA进行解旋,也不影响拓扑异构酶II。
