ABSTRACT
A series of 6-azanaphthoquinone pyrrolo-annelated derivatives carrying different basic side chains have been synthesized. The antiproliferative activities of all compounds were evaluated on at least four different cell lines with Mitoxantrone as reference compound. Cytotoxic effects and DNA intercalation behavior were investigated.

Two series of azanaphthoquinone annelated pyrrolo oximes have been synthesized. The antiproliferative activities of 10 compounds were evaluated on at least four different cell lines. One series of pyrrolo derivatives showed high cytotoxic activity. The effects on cell cycle and caspase activity were investigated. Compounds 9a and 9b showed an accumulation of cells in G2/M phase. Substantial and dose-dependent caspase activity was found after treatment of cells with 9a and 9b. This indicates an apoptosis inducing property of these compounds.
