A composition comprising the following structure: (formula I) wherein Re represents a rhenium ion having a +1 charge; (formula II) represents an uncharged bidentate bicyclic ligand bonded to the rhenium (Re) by two ring nitrogen (N) atoms; and L is a neutral ligand independently selected from CO and neutral phosphine molecules, wherein at least one of the L groups is a CO molecule; and X− represents a non-coordinating monovalent anion; wherein (formula II) is unsubstituted or substituted on any of its two rings, and said neutral phosphine molecule may or may not contain a phosphorus atom as a ring phosphorus atom; provided that, if (formula II) is unsubstituted, then one or two of said L groups are selected from said neutral phosphine molecules, with the provision that at least one of the neutral phosphine molecules has a phosphorus atom as a ring phosphorus atom. Methods for treating cancer by administering the above complex are also disclosed.
一种由以下结构组成的组合物:(式 I) 其中 Re 代表具有 +1 电荷的铼离子;(式 II) 代表通过两个环氮 (N) 原子与铼 (Re) 键合的无电荷双齿双环配体;以及 L 是独立选自 CO 和中性膦分子的中性配体,其中至少一个 L 基团是 CO 分子;以及 X- 代表非配位一价阴离子;其中(式 II)在其两个环的任何一个上未被取代或被取代,所述中性膦分子可以含有或不含有作为环磷原子的磷原子;条件是,如果(式 II)未被取代,则所述 L 基团中的一个或两个选自所述中性膦分子,并规定至少一个中性膦分子具有作为环磷原子的磷原子。还公开了通过施用上述复合物治疗癌症的方法。
