The present invention discloses a one-step process for the production of cytotoxic conjugates of maytansinoids and cell binding agents. Maytansinoids having a disulfide linker that bears a reactive moiety are linked to cell binding agents, such as antibodies, without prior modification of the cell binding agent. These conjugates are useful as therapeutic agents which are delivered specifically to target cells and are cytotoxic.
本发明揭示了一种一步法生产细胞毒性马替蒂诺伊德和细胞结合剂偶联物的方法。具有含有反应性基团的二
硫键连接剂的马替蒂诺伊德与细胞结合剂(如
抗体)结合,无需事先对细胞结合剂进行修饰。这些偶联物可用作治疗剂,可专门传递到靶细胞并具有细胞毒性。
