Advances in the Development of Ferroptosis‐Inducing Agents for Cancer Treatment

ABSTRACT Cancer is the main leading cause of death worldwide and poses a great threat to human life and health. Although pharmacological treatment with chemotherapy and immunotherapy is the main therapeutic strategy for cancer patients, there are still many shortcomings during the treatment such as incomplete killing of cancer cells and development of drug resistance. Emerging evidence indicates the promise of inducing ferroptosis for cancer treatment, particularly for eliminating aggressive malignancies that are resistant to conventional therapies. This review covers recent advances in important regulatory targets in the ferroptosis metabolic pathway and ferroptosis inducers (focusing mainly on the last 3 years) to delineate their design, mechanisms of action, and anticancer applications. To date, many compounds, including inhibitors, degraders, and active molecules from traditional Chinese medicine, have been demonstrated to have ferroptosis‐inducing activity by targeting the different biomolecules in the ferroptosis pathway. However, strictly defined ferroptosis inducers have not yet been approved for clinical use; therefore, the discovery of new highly active, less toxic, and selective compounds remains the goal of further research in the coming years.
