Metal Complexes Stimulating Immunogenic Pyroptosis as Burgeoning Antitumor Strategy

Area of Science:

• Materials Science
• Oncology
• Immunology

Background:

• The need for novel antitumor agents with diverse mechanisms is critical in cancer research and clinical oncology.
• Metal complexes offer unique properties for developing therapeutic and diagnostic cancer agents.
• Pyroptosis, an inflammatory programmed cell death, is gaining attention for its role in antitumor immunity.

Purpose of the Study:

• To review recent advancements in antitumor metal complexes designed to induce pyroptosis.
• To elucidate the mechanisms by which these metal complexes stimulate pyroptosis.
• To explore the potential of metal complex-based pyroptosis inducers in cancer therapy and immunotherapy.

Main Methods:

• Review of current literature on metal complexes and pyroptosis induction.
• Analysis of pyroptosis-stimulating mechanisms across various therapeutic modalities (chemo-, photo-, sono-, targeted therapy).
• Dissection of the interplay between pyroptosis, inflammasome activation, gasdermin cleavage, and immune reprogramming.

Main Results:

• Metal complexes can effectively induce pyroptosis through diverse therapeutic approaches.
• Understanding the molecular mechanisms of pyroptosis induction by metal complexes is crucial.
• These complexes can reprogram the tumor microenvironment and enhance antitumor immunity.

Conclusions:

• Antitumor metal complexes that induce pyroptosis represent a promising strategy for cancer treatment.
• These agents can synergize with immunotherapies by modulating the tumor immune response.
• Further development of metal complex-based pyroptosis inducers holds potential for innovative cancer therapies.
