Abstract

Cancer cells display an overproduction of reactive oxygen species resulting from an exaggerated intrinsic oxidative stress. However, the concept of deleterious oxidants versus beneficial antioxidants has recently evolved. Indeed, molecules like natural coumarins have shown anti-oxidant or pro-oxidant properties depending on their intracellular concentration. Therefore, we have investigated the structure-activity relationship of a variety of coumarin derivatives in terms of cytotoxicity towards human and murine carcinoma cell lines (HT29, HepG2, A549, MCF7, OVCAR and CT26). Amongst those compounds, (E)-7-methoxy-4-(3-oxo-3- phenylprop-1-enyl)-2H-chromen-2-one and (E)-7-hydroxy-4-(3-(4-hydroxyphenyl)-3-oxoprop-1-enyl)-2H-chromen-2-one displayed the most potent cytotoxic effect on colon cancer cells, CT26, (IC50=4.9µM) linked to their pro-oxidant properties. Those compounds triggered the in vitro production of reactive oxygen species by tumor cells, leading to their death through a necrotic process. In vivo, molecules also slowed down tumor growth by 65.7% and 35.4%, respectively, without inducing significant side effects.
