Bio-reductive hetero-bimetallic Co(III)-Pt(II) complex for tumor-selective platinum release and cytotoxicity

Key Points

• The aim is to investigate a bioreductive metalloprodrug for selective activation and cytotoxicity in tumor environments.
• Development of a hetero-bimetallic Co(III)-Pt(II) complex
• Assessment of cytotoxic effects in reductive tumor microenvironments
• Comparison of release rates of platinum in tumor versus normal conditions
• The Co(III)-Pt(II) complex exhibited enhanced platinum release in tumor-like reductive conditions
• Significant cytotoxic effects were observed in tumor cells compared to normal cells
• The bioreductive activation mechanism showed promise for improved cancer therapy
