This invention relates to novel analogs of the DNA-binding alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and their conjugates. The conjugates are designed to release their (multiple) payload after one or more activation steps and/or at a rate and time span controlled by the conjugate in order to selectively deliver and/or controllably release one or more of said DNA alkylating agents. The agents, conjugates, and intermediates can be used to treat an illness that is characterized by undesired (cell) proliferation. As an example, the agents and the conjugates of this invention may be used to treat a tumor.

This invention relates to compounds comprising one or more therapeutic and/or diagnostic moieties and one or more functional moieties linked together via one or more triazole-containing linkers and to their intermediates and methods of their preparation. The triazole-containing linker may optionally contain one or more conditionally-cleavable or conditionally-transformable moieties and one or more spacer systems in between said moiety/moieties and the one or more therapeutic and/or diagnostic moieties.

The present invention relates to a method for purifying a mixture of cysteine-linked antibody-drug conjugates, wherein the amount of non-conjugated antibody is in the range of 0-40% by weight, using hydrophobic interaction chromatography (HIC). The mixture is loaded onto a preparative HIC column using a 0.2-1.5 M aqueous salt solution, in which non-conjugated antibody is collected in a flow-through fraction, followed by elution of a purified mixture of cysteine-linked antibody-drug conjugates using a 0-100 mM aqueous salt solution.
本发明涉及一种利用疏水相互作用色谱法(HIC)纯化半胱氨酸连接抗体-药物共轭物混合物的方法,其中非结合抗体的量按重量计在 0-40% 的范围内。使用 0.2-1.5 M 的水盐溶液将混合物装载到制备型疏水相互作用色谱柱上,在流过部分收集非结合抗体,然后使用 0-100 mM 的水盐溶液洗脱纯化的半胱氨酸连接抗体-药物共轭物混合物。
