Cisplatin interferes with DNA replication, which kills the fastest proliferating cells, which in theory are cancerous. Following administration, one chloride ion is slowly displaced by water to give the aquo complex cis-[PtCl(NH3)2(H2O)] , in a process termed aquation. Dissociation of the chloride is favored inside the cell because the intracellular chloride concentration is only 3–20% of the approxi…
WebCisplatin is a front-line drug in treatment of most solid tissue cancers. It kills cancer cells by damaging their DNA. Although it is quite effective it has two major drawbacks. First, it has serious side effects, including nephrotoxicity, hepatotoxicity, and neurotoxicity. WebAnticancer activity of cisplatin (cis-diamminedichloroplatinum) is believed to result from its interaction with DNA. The drug reacts with nucleophilic sites in DNA forming …
WebThe other mechanism that could perpetuate resistance of the cisplatin to tumor cells is the increased repair of the damaged DNA. 19 In the previous section, we outlined the importance of the formation and persistence of DNA adducts as an essential inducing mechanisms for apoptosis that is responsible for cell death.
