WebSep 15, 2024 · Cisplatin is the prototype platinum coordination complex classified as an alkylating agent and used intravenously in the treatment of several forms of cancer. Cisplatin has been associated with a low rate of serum enzyme elevations and with rare cases of clinically apparent, acute liver injury. WebAlkylating agents are antineoplastic drugs that work by inhibiting the transcription of DNA to RN by alkylation. Alkylation is the process of adding an alkyl group ( CH3) to DNA. This process prevents the DNA from being used in protein synthesis and the production of new cells, including cancer cells.
