RESUMEN
Reactive oxygen species (ROS) which were partial metabolites of oxygen are highly reactive. Different concentrations of ROS have different effects on tumor development. Tumor cells have a high level of reactive oxygen species. The antioxidant system of tumor is in highly activated state, and thus modulation of reactive oxygen species levels could be an effective strategy to target cancer cells. Treatment with small molecules that disrupt the redox balance can kill tumor cells first. This paper outlines the main ideas of developing anti-tumor drugs based on reactive oxygen species regulation, and summarizes the representative drugs and research progress according to the mechanism of action, in an effort to suggest potential reference and ideas for developing anti-tumor drugs based on reactive oxygen species regulation.
