Bioorg Med Chem. 2011 Mar 15;19(6):1924-9. doi: 10.1016/j.bmc.2011.01.064. Epub 2011 Feb 3.

Abstract

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.
