Abstract:
Cancer treatments, including traditional chemotherapy, have failed to cure human malignancies. The main reasons for the failure of these treatments are the inevitable drug resistance and serious side effects. In clinical treatment, only 5 percent of the 50 percent of cancer patients who are able to receive conventional chemotherapy survive. Because of these factors, being able to develop a drug and treatment that can target only cancer cells without affecting normal cells remains a big challenge. Since the special properties of cisplatin in the treatment of malignant tumors were accidentally discovered in the last century, metal anticancer drugs have become a research hotspot. Metal anticancer drugs have unique pharmaceutical properties, such as ruthenium metal drugs with their high selectivity, low toxicity, easy absorption by tumor tissue, excretion, and so on. In recent years, efficient and low-toxicity metal antitumor complexes have been synthesized. In this paper, the scientific literature on platinum (Pt), ruthenium (Ru), iridium (Ir), gold (Au), and other anticancer complexes was reviewed by referring to a large amount of relevant literature at home and abroad.
Insights

Background:
- Traditional chemotherapy faces limitations due to drug resistance and severe side effects, with low survival rates for treated patients.
- The development of targeted cancer therapies that spare normal cells remains a significant challenge in clinical oncology.
- The discovery of cisplatin's anticancer properties spurred research into metal-based drugs, a field that has since become a major focus.
Purpose of the Study:
- To review the scientific literature on metal-based anticancer complexes, focusing on their potential to overcome chemotherapy's limitations.
- To highlight the unique pharmaceutical properties of metal drugs, such as ruthenium complexes, including selectivity and low toxicity.
- To provide an overview of recent advancements in the synthesis of efficient and low-toxicity metal antitumor complexes.
Main Methods:
- Comprehensive literature review of domestic and international scientific publications.
- Analysis of research on metal anticancer complexes, including platinum (Pt), ruthenium (Ru), iridium (Ir), and gold (Au).
- Synthesis and characterization of novel metal antitumor complexes were referenced from existing studies.
Main Results:
- Metal-based drugs, particularly ruthenium complexes, demonstrate high selectivity and low toxicity compared to traditional agents.
- Recent research has led to the synthesis of efficient metal antitumor complexes with improved therapeutic profiles.
- The reviewed literature indicates a growing body of evidence supporting the potential of various metal complexes in cancer treatment.
Conclusions:
