Platinum-based antineoplastic drugs (informally called platins) are chemotherapeutic agents to treat cancer. They are coordination complexes of platinum. The main dose-limiting side effect of cancer treatment with platinum compounds is neurotoxicity, which causes peripheral neuropathies including polyneuropathy. ==Mechanism of action== As studied mainly on cisplatin, but presumably for other members as well, platinum-based antineoplastic agents cause crosslinking of DNA as monoadduct, interstrand crosslinks, intrastrand crosslinks or DNA protein crosslinks. Mostly they act on the adjacent N-7 position of guanine, forming 1, 2 intrastrand crosslink. The resultant crosslinking inhibit DNA repair and/or DNA synthesis in cancer cells. Platinum-based antineoplastic agents are sometimes described as "alkylating-like" due to similar effects as alkylating antineoplastic agents, although they do not have an alkyl group. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Platinum-based antineoplastic」の詳細全文を読む スポンサード リンク
