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结合物,特别是但不限于它们在选择性消除和选择性成像靶细胞中的使用方法。该发明还涉及生产这些结合物的过程,以及可能用于生产特定类别细胞靶向结合物的中间化合物。在一种实施方式中,提供了一个细胞靶向结合物,包括以下组分,这些组分通过可在靶细胞内降解的链接物共价结合:i) 一种包含有效的奥杰电子发射和/或γ射线发射和/或正电子发射原子或光活性基团的DNA小沟结合配体;ii) 一种能够被靶细胞内部化的靶细胞特异性蛋白质或肽。
