WebCisplatin enters the cell either passively or through a transporter, where two water molecules replace the chloride groups. As an electrophile, cisplatin is attracted to the nitrogen on purine bases in the DNA, where it forms inter or intra-strand crosslinks, interrupting DNA repair and replication processes. WebCisplatin (DDP) has been a significant tumor chemotherapy against various solid malignant tumors, including lung adenocarcinoma, since it was approved by the Food and Drug Association in 1978.7Platinum chemotherapy drugs, represented by DDP, are antitumor agents.

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… WebOct 20, 2003 · Cisplatin is one of the most potent antitumor agents known, displaying clinical activity against a wide variety of solid tumors. Its cytotoxic mode of action is mediated by its interaction with DNA to form DNA adducts, primarily intrastrand crosslink adducts, which activate several signal transducti …
