In the search for new metal-based anticancer agents as effective candidates for cisplatin, a lot of strategies such as synthesis
of cisplatin analogs, trans-platinum compounds and non-platinum metal complexes have been put forward in the last forty years. The
concept of multinuclearity for improving the chemotherapeutic activity has been proven in multinuclear platinum complexes such as
BBR3464, recently, the effective approach has been successfully transferred to ruthenium complexes. In this review, we highlighted the
recent progress in multinuclear platinum complexes and ruthenium complexes as anticancer agents, and their novel DNA binding
properties such as phosphate clamps, long range DNA cross links, bisintercalation, interduplex cross links and DNA-protein cross-links
were summarized to shed light on the rational design of polynuclear complexes as anticancer agents.
Keywords: Cytotoxicity, DNA binding, metal-based anticancer agents, multinuclear complexes, platinum complexes, ruthenium complexes.
