  摘要：

  为了设计和合成通过抑制拓扑异构酶I（top1）发挥作用的潜在抗癌药，制备了一系列新的茚并异喹啉并测试了其在人类癌细胞培养中的细胞毒性以及对top1的活性。该合成依赖于取代的席夫碱与高邻苯二甲酸酐的缩合，以产生顺式-3-芳基-4-羧基异喹啉酮，其在亚硫酰氯存在下环化成茚并异喹啉。在单个化合物6- [3-（2-羟乙基）氨基丙基] -5,6-二氢-2,3-二甲氧基-8，9-亚甲基二氧基-5,11-二氧代-11H中，top1的抑制活性和细胞毒性均最大化。 -茚并[1,2-c]异喹啉盐酸盐（19a）被证明是一种非常有效的top1抑制剂，在55种人类癌细胞培养物中进行细胞毒性测试时，其平均图中点（MGM）为110 nM。还获得了许多与结构相关的茚并异喹啉，它们既具有有效的细胞毒性，又具有top1抑制活性。更有效的化合物的关键特征是在茚并异喹啉氮原子上存在氨基烷基侧链。在存在茚并异喹啉的情况下，top1

  A number of indenoisoquinolines were prepared and evaluated for cytotoxicity in human cancer cell cultures and for activity vs. 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-hydroxybut-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.

  A number of indenoisoquinolines were prepared and evaluated for cytotoxicity in human cancer cell cultures and for activity vs topoisomerase 1 (top1). 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 (21) and cis-6-allyl-5,6,12,13-tetrahydro-2,3-dimethoxy-6,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (22), both of which displayed submicromolar mean graph midpoints when tested in 55 human cancer cell cultures. Two of the most potent top1 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), both of which also inhibited top2, unwound DNA, and are assumed to be DNA intercalators. However, two additional potent top1 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-hydroxybut-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 top2, Some of the DNA cleavage sites detected in the presence of the indenoisoquinolines were different from those seen with the camptothecins. The cleavage sites induced by the indenoisoquinolines were reversed by salt treatment, which is consistent with the reversible trapping of top1 cleavable complexes by the indenoisoquinolines. In general, the potencies of the indenoisoquinolines as top1 inhibitors did not correlate with their potencies as cytotoxic agents, as some of the most cytotoxic agents had little if any effect on top1. On the other hand, the most potent of the indenoisoquinolines vs top1 were not the most-cytotoxic. In several cases, moderate activity was observed for both cytotoxicity and activity vs top1.
