Cisplatin, cisplatinum, or cis-diamminedichloroplatinum(II) (CDDP) is a platinum-based chemotherapy drug used to treat various types of cancers, including sarcomas, some carcinomas (e.g. small cell lung cancer, and ovarian cancer), lymphomas, and germ cell tumors. It was the first member of a class of anti-cancer drugs which now also includes carboplatin and oxaliplatin. These platinum complexes react in vivo, binding to and causing crosslinking ...

Cisplatin, cisplatinum, or cis-diamminedichloroplatinum(II) (CDDP) is a platinum-based chemotherapy drug used to treat various types of cancers, including sarcomas, some carcinomas (e.g. small cell lung cancer, and ovarian cancer), lymphomas, and germ cell tumors. It was the first member of a class of anti-cancer drugs which now also includes carboplatin and oxaliplatin. These platinum complexes react in vivo, binding to and causing crosslinking of DNA which ultimately triggers apoptosis (programmed cell death).
Following administration, one of the chloride ligands is slowly displaced by water (an aqua ligand), in a process termed aquation. The aqua ligand in the resulting [PtCl(H2O)(NH3)2] is itself easily displaced, allowing the platinum atom to coordinate to a basic site in DNA. Subsequently, crosslinking of two DNA bases occurs via displacement of the other chloride ligand. Cisplatin crosslinks DNA in several different ways, interfering with cell division by mitosis. The damaged...
