Convenient synthesis of indeno[1,2-c]isoquinolines as constrained forms of 3-arylisoquinolines and docking study of a topoisomerase I inhibitor into DNA-topoisomerase I complex

Bioorg Med Chem Lett. 2007 Nov 1;17(21):5763-7. doi: 10.1016/j.bmcl.2007.08.062. Epub 2007 Aug 29.

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-(i)butoxy 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.
