摘要

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 ...
