Various 5-amino group-substituted indeno[1,2-c]isoquinolines 7a-f were synthesized based on the previous QSAR study as rigid structures of 3-arylisoquinolines. Amino group-substituted compounds, especially 5-piperazinyl indeno[1,2-c]isoquinoline 7f, displayed potent topoisomerase I inhibitory activity as well as cytotoxicities against five different tumor cell lines. A Surflex-Dock docking model of 7f was also studied.
基于之前的定量构效关系研究，我们合成了各种 5-氨基取代的茚并[1,2-c]异喹啉 7a-f，作为 3-芳基异喹啉的刚性结构。氨基取代的化合物，特别是 5-哌嗪基茚并[1,2-c]异喹啉 7f，表现出很强的拓扑异构酶 I 抑制活性和对五种不同肿瘤细胞系的细胞毒性。还研究了 7f 的 Surflex-Dock 对接模型。
