We report the synthesis and evaluation as potential anticancer agents of a series of tetracyclic indenoquinolines. The compounds, which are obtained through the photoisomerization of Diels-Alder adducts formed between purpurogallin derivatives and nitrosobenzene, have in vitro antiproliferative activities in the μM to nM range against breast (MCF-7), lung epithelial (A-549), and cervical (HeLa) adenocarcinoma cells. The cytotoxicities of several of the novel tetracycles are comparable to or better than that of camptothecin. A strong correlation between the activity of the compounds and their aromaticity and planarity was observed, suggesting a mode of action similar to that of topoisomerase poisons.
