Abstract

11-Hydroxyindeno[1,2-c]isoquinolines 12a-c were prepared as constrained forms of 3-arylisoquinolines through an intramolecular cyclization reaction. Among the synthesized compounds, the 11-ibutoxy analog 15l displayed potent in vitro cytotoxicity against four different tumor cell lines as well as topoisomerase 1 inhibitory activity. A FlexX docking study was performed to explain the topoisomerase 1 activity of 15l.
