Carboplatin, a derivative of CDDP, is a DNA synthesis inhibitor which binds to DNA, inhibits replication and transcription and induces cell death and interfers with the cell’s repair mechanism in A2780, SKOV-3, IGROV-1, and HX62 cells. It induces the formation of DNA interstrand crosslinks and DNA-protein crosslinks. Solutions are unstable and should be fresh-prepared.DMSO is not recommended to dissolve platinum-based drugs, which can easily lead to drug inactivation.
