Bio-inspired cisplatin nanocarriers for osteosarcoma treatment

Author affiliations


In this study, cisplatin (cis-diaminedichloroplatinum, CDDP) nanocarriers with phosphorylcholine surface tailoring were developed to enhance the anti-tumor potential of CDDP for the treatment of osteosarcoma. Poly(2-methacryloyloxyethyl phosphorylcholine)-b-poly(methacrylic acid) (PMPC-b-PMAA) was synthesized for the preparation of CDDP/PMPC-b-PMAA micelles. The synthesis, self-assembly, and in vitro drug release were well characterized. In vitro cytotoxicity showed that CDDP/PMPC-b-PMAA micelles can strongly inhibit the proliferation of Saos-2 cells. In vivo experiments indicated that CDDP/PMPC-b-PMAA micelles showed prolonged circulation time, reduced renal accumulation, and enhanced tumor accumulation compared to free CDDP. Overall, the CDDP/PMPC-b-PMAA micelles exhibited optimal anti-tumor activity with minimal side effects in the treatment of osteosarcoma.
