Development of novel drugs or drug delivery systems has attracted much attention of researchers. In this study, we aimed to prepare 2 new Pt(II) complexes with thiosemicarbazone and their nanoformulations for cancer treatment application. Pt(II)-camphor thiosemicarbazone/P1 and Pt(II)-camphor 4-phenyl thiosemicarbazone/P2) were successfully prepared and structurally confirmed by MS, IR, 1H-NMR, UV–vis spectroscopies and thermal analysis. From the complexes, 2 PLGA-based nanoformulations (nP1 and nP2) were synthesised with the average size of 50 nm by emulsification/evaporation method and investigated for their toxicity against Hep-G2, LU-1 and RD cancer cell lines. The results show that the Pt(II) complexes and their nanoformulations were potential for chemotherapy.
