Some synthetic 1-azabenzanthrones (7H-dibenzo[de,h]quinolin-7-ones) are weakly to moderately cytotoxic, suggesting that they might also show antiparasitic activity. We have now tested a small collection of these compounds in vitro against a chloroquine-resistant Plasmodium falciparum strain, comparing their cytotoxicity against normal human fibroblasts. Our results indicate that 5-methoxy-1-azabenzanthrone and its 2,3-dihydro analogue have low micromolar antiplasmodial activities and showed more than 10-fold selectivity against the parasite, indicating that the dihydro compound, in particular, might serve as a lead compound for further development.

Anthraquinone derivatives are well-known antiproliferative compounds, and some are currently used in cancer chemotherapy. Some families of annulated anthraquinone analogs have also been examined for antiproliferative activity, but in this regard almost nothing is known of 1-azabenzanthrones (7H-dibenzo[de,h]quinolin-7-ones). A series of 1-azabenzanthrone derivatives, their 2,3-dihydro analogs, and
