Sertaconazole nitrate targets IDO1 and regulates the MAPK signaling pathway to induce autophagy and apoptosis in CRC cells.

Colorectal cancer (CRC) has become the third most frequently occurring malignant tumor worldwide. It is vital to identify novel, effective targeted treatments while considering side effects and drug resistance in the clinic. Recently, the tryptophan-metabolizing enzyme indole-2, 3-dioxygenase 1 (IDO1) has been widely reported to be overexpressed in CRC, indicating that blocking IDO1 with small-molecule inhibitors may be a promising approach to CRC treatment.

Ferroptosis-related small-molecule compounds in cancer therapy: Strategies and applications.

Ferroptosis is a novel type of regulated cell death which is driven by iron-dependent lipid peroxidation and subsequent plasma membrane ruptures. Since ferroptosis was coined fairly in 2012, the research in the field of ferroptosis has grown at an exponential rate. Several small-molecule drugs have been shown to trigger ferroptosis and decrease tumor growth in the last decade.
