Abstract

Polyoxometalates (POMs) have shown promising antitumor activities attributed to their virtue of incomparable structural versatility and interesting redox properties. However, the clinical application of POM drugs is limited by their poor stability and low anticancer specificity. To overcome these shortcomings, a multifunctional platform based on POMs (the tetrabutylammonium salts of [PW12O40]3−, [V10O28H3]3− and [Mo6O19]2−) and MIL-100 (Fe) was successfully developed for combined chemical and chemodynamic therapy, ultimately inducing cancer cell apoptosis. The prepared POMs@MIL-100 (Fe) composites showed great efficiency in killing MCF-7 and 4T1 cells while with a low toxicity to normal MCF-10A and C2C12 cells.
