Cancer is widely recognized as a serious disease that poses a significant threat to human life and health. The distinctive chemical properties and pronounced antiproliferative activity of platinum drugs are considered to be responsible for their remarkable efficacy in clinical applications. However, undesirable side effects and resistance have severely hampered the treatment of various types of cancer with platinum-based drugs. Natural products (NPs) exhibit extensive pharmacological activities and represent an important source for developing cancer therapeutics. Therefore, the combination of metals and NPs is an attractive strategy for the development of new anticancer agents. Several studies have indicated that combining metals with NPs has a synergistic enhancement effect in antitumor activity. For transition metals, there has been burgeoning research output investigating NP-conjugated platinum and gold complexes. The present article reviews the progress made over the past 5-10 years on the development of NP-conjugated platinum and gold complexes, including a brief introduction to their chemistry and mechanism of action, and a summary of their benefits.
