WebPlatinum compounds. The platinum compounds are largely used in the treatment of lung, breast, ovarian, and colon cancers. The chemotherapeutic mechanism of platinum compounds is typical of DNA-binding alkylating agents. If the DNA damage exceeds the ability of the cell to repair, the cell undergoes apoptotic cell death. WebBecause alkylating agents are active against cells in G0, they can be used to debulk tumours, causing resting cells to be recruited into active division. At this point, those cells are vulnerable to the cell cycle-specific agents. These agents are active against lymphomas, Hodgkin's disease, breast cancer, and multiple myeloma. 1, 7, 11
