     摘要：抗肿瘤抗生素是微生物产生的活性物质。利用特定的模型和方法进行筛选或对已知化合物进行检测，已发现与报告对各种分子靶点显示高度活性的抗肿瘤抗生素。某些抗肿瘤抗生素如卡里奇霉素、力达霉素等对癌细胞有极强的杀伤作用，可以作为高效“弹头”药物，用于构建抗体靶向药物包括化学免疫偶联物和融合蛋白。抗肿瘤抗生素与抗体工程技术的结合可以作为新的技术平台，制备一系列的针对不同靶点的、用于治疗癌症的抗体靶向药物。

    ABSTRACT Antitumor antibiotics are tumoractive substances produced by microorganisms. By screening or testing with particular assays, a number of antibiotics that display potent activity respectively to various molecular targets have been reported. Some antitumor antibiotics such as calicheamicin and lidamycin which exert extremely potent cytotoxicity to cancer cells can be used as potent "warhead" agent to constitute antibodybased drugs including chemoconjugates and fusion proteins. The integration of antitumor antibiotic and antibody engineering can serve as new technical platform for manufacture of a series of various targetspecific antibodybased drugs for cancer therapy. ......
