The present invention relates to metal complexes bearing at least one (E-E')-4,4'- bisstyryl-2,2'-bipyridine ligand (LIG1) of the following formula (I): or a pharmaceutically acceptable salt and/or solvate thereof. The present invention also relates to pharmaceutical compositions comprising these complexes and at least one pharmaceutically acceptable excipient. The present invention also relates to the use of compounds of formula (I) or pharmaceutical compositions comprising thereof as drug and as photosensitizer agent in photodynamic therapy. The present invention also relates to methods of preparation of said complexes.
Physical, spectroscopic, and biological properties of ruthenium and osmium photosensitizers bearing diversely substituted 4,4′-di(styryl)-2,2′-bipyridine ligands
Capitalising on the previous identification of a distyryl coordinated Ru(II) polypyridine complex as a promising photosensitizer for photodynamictherapy, eight new complexes were synthesized by modifications of the ligands or by changing the metal coordinated. We report in this work the effects of these modifications on the physical, spectroscopic, and biological properties of the synthesized complexes
