We examined the relationship between the structures of hetero-/homoleptic ruthenium(II) tris(bipyridine) metal complexes (RuII(bpy)3) and their binding properties for α-chymotrypsin (ChT) and cytochrome c (cyt c). Heteroleptic compound 1a binds to both ChT and cyt c in 1:1 ratio, whereas homoleptic 2 forms 1:2 protein complex with ChT but 1:1 complex with cyt c. These results suggest that the structure of the recognition cavity in RuII(bpy)3can be designed for shape complementarity to the targeted proteins. In addition, RuII(bpy)3complexes were found to be potent inhibitors of cyt c reduction and to permeate A549 cells.
