Phenazine 5,10-dioxides are prodrugs for antitumor therapy that undergo hypoxic-selective bioreduction to form cytotoxic species. Here we investigate the expanded system benzo[a]phenazine 7,12-dioxides as selective hypoxic cytotoxin-scaffold. The clonogenic survival of V79 cells on aerobic and anaerobic conditions, conduct us to study antiproliferative activity on Caco-2 tumoral cells in normoxia. Electrochemical, DNA-interaction and DNA-damage studies were performed to establish the mode of action. The results demonstrated the potential biological properties of the studied scaffold being derivatives 6-10 structural hits for further chemical-modifications to become into therapeutics for solid tumors. Compounds 6 and 8 with cytotoxicity against V79 cells in both conditions (aerobia and anaerobia) were also cytotoxic against Caco-2 tumoral cells in aerobiosis.

Several phenazine 5,10-dioxides (7a-d) were prepared by the reaction of 2-methyl-3-acetylquinoxaline 1,4-dioxide (2) with different aromatic aldehydes or by direct cyclization of the quinoxaline cinnamoyl derivatives 3 in basic medium.In addition, the phe
