Abstract:
Cancer remains the second leading cause of death worldwide. Research is currently focused on finding novel anticancer therapies and elucidating their mechanisms of action. Cellular redox balance is a promising target for new therapies, as cancer cells already have elevated levels of oxidizing agents due to hypermetabolism and genetic instability. Although free radicals are actively involved in vital cellular signaling pathways, they have also been implicated in certain diseases, including cancer. The aim of this review was to highlight the involvement of oxidative stress in the mechanism of action of anticancer agents. The difference in cellular redox balance between normal and cancer cells is discussed as a potential anticancer target, along with various examples of approved or experimental drugs that may alter the redox state. These drugs are presented in relation to their pro-oxidant or antioxidant mechanisms, with the consequent goal of underscoring the importance of such mechanisms in the overall efficacy of anticancer drugs.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
