<p>A binuclear DNA-threading transition metal complex with the general formula: (L1)-M1-(D1-B-D2)-M2-(L2) wherein D1-B-D2 is a bridging ligand; D1 is a polycyclic heteroaromatic ligand in which aza nitrogens can form a bidentate or tridentate chelate with M1; D2 is any bi- or oligodentate ligand co-ordinated to the transition metal M2; B is any appropriately substituted chain of at least two atoms; M1 is a transition metal ion with octahedral co-ordination sphere; M2 is any transition metal ion; L1 comprises a set of 1-3 ancillary ligands that saturate the remaining co-ordination sphere of M1; and L2 comprises a set of 1-4 ancillary ligands that saturate the remaining co-ordination sphere of M2. An example of the complex according to the invention is shown in the figure 1. The complex according to the invention is useful for treatment of different diseases, such as cancer and infections.</p> |
