This invention describes carrier-drug conjugates prepared from disulfide analogs of the calicheamicin family of potent antitumor antibiotics and their derivatives, as well as similar analogs from related antitumor antibiotics such as the esperamicins. The carrier can be an antibody, growth factor, or steroid which targets an undesired population of cells, such as those of a tumor. Whole protein carriers as well as their antigen-recognizing fragments and their chemically or genetically manipulated counterparts are useful for the targeting portion of the conjugates. This invention includes compounds required for the synthesis of these conjugates, appropriate pharmaceutical compositions of the carrier-drug conjugates, and their method of use.
本发明描述了由强效抗肿瘤抗生素calicheamicin家族的二硫键类似物及其衍生物以及类似的esperamicins的类似物制备的载体-药物共轭物,载体可以是抗体、生长因子或类固醇,其针对不需要的细胞群体,例如肿瘤细胞。整个蛋白质载体以及它们的抗原识别片段和它们的化学或基因操作的对应物对于共轭物的靶向部分是有用的。本发明包括用于这些共轭物的合成所需的化合物,载体-药物共轭物的适当药物组成以及它们的使用方法。
