The present invention relates to cell targeting conjugates and in particular, but not exclusively, to methods of their use in selectively eliminating and in selectively imaging target cells. The invention also relates to processes for production of the conjugates and to intermediate compounds that may be used in production of a specific class of cell targeting conjugates. In one embodiment there is provided a cell targeting conjugate comprising the following components that are covalently conjugated via a linker that is degradable within the target cells: i) a DNA minor groove binding ligand incorporating an effective Auger electron-emitting and/or gamma-emitting and/or positron-emitting atom or photoactive moiety; ii) a target cell specific protein or peptide that is capable of internalisation by target cells.
本发明涉及细胞靶向共轭物,特别是但不仅限于它们在选择性消除和选择性成像目标细胞中的使用方法。该发明还涉及制备共轭物的过程以及可用于制备特定类别的细胞靶向共轭物的中间化合物。在一种实施方式中,提供了一个细胞靶向共轭物,其包括以下成分,这些成分通过可在目标细胞内降解的连接剂共价结合:i)DNA小沟结合配体,包含有效的Auger电子发射和/或γ射线发射和/或正电子发射原子或光活性基团;ii)能够被目标细胞内化的目标细胞特异性蛋白质或肽。
