Recent advances in natural compounds inducing non-apoptotic cell death for anticancer drug resistance

The induction of cell death is recognized as a potent strategy for cancer treatment.Apoptosis is an extensively studied form of cell death,and multiple anticancer drugs exert their therapeutic effects by inducing it.Nonetheless,apoptosis evasion is a hallmark of cancer,rendering cancer cells resistant to chemotherapy drugs.Consequently,there is a growing interest in exploring novel non-apoptotic forms of cell death,such as ferroptosis,necroptosis,pyroptosis,and paraptosis.Natural compounds with anticancer properties have garnered significant attention due to their advantages,including a reduced risk of drug resistance.Over the past two decades,numerous natural compounds have been discovered to exert anticancer and anti-resistance effects by triggering these four non-apoptotic cell death mechanisms.This review primarily focuses on these four non-apoptotic cell death mechanisms and their recent advancements in overcoming drug resistance in cancer treatment.Meanwhile,it highlights the role of natural compounds in effectively addressing cancer drug resistance through the induction of these forms of non-apoptoticcell death.
