Cuproptosis, a copper-induced cell death mechanism, offers a new therapeutic approach. Here, we identified a marine natural product, chagosendine C (CHC), which kills tumor cells by increasing the intracellular copper ion concentration. CHC and related metal coordination homodimer alkaloids were rapidly synthesized and purified for further pharmacological study. , CHC significantly inhibited HCT116 and RKO CRC cell growth, induced G1 phase arrest and cell death, and overcame oxaliplatin resistance. , CHC suppressed colorectal tumor growth in mice at 40 mg/kg without obvious toxic effects. Mechanistically, CHC induces cuproptosis by targeting FDX1, increasing intracellular copper ions and ROS levels in tumor cells, and leading to cell death. Thus, CHC presents a novel CRC treatment strategy, showing strong antitumor activity and potential to overcome oxaliplatin resistance with promising clinical prospects.
