Research Progress on Elesclomol-Induced Cuproptosis for Antitumor Effects

T cell infiltration, demonstrating synergistic effects with immune checkpoint blockade therapies. However, tumor cells can develop resistance mechanisms through metabolic reprogramming via hypoxia-inducible factor-1α (HIF-1α) and the nuclear factor E2-related factor 2 (Nrf2)-driven reductive pathway, which partially limits the drug's clinical efficacy. Addressing this limitation, combination therapies integrating elesclomol with targeted agents such as ferroptosis inducers or chemotherapeutic drugs have demonstrated significant antitumor advantages. Future research must urgently leverage the selection of precise biomarkers and the development of novel intelligent nanodelivery systems to further advance the safe and efficient clinical translation of elesclomol.
