<abstract xmlns="http://www.w3.org/1999/xhtml">The interactions of metal complexes with important biomolecules such as deoxyribonucleic acid (DNA) or bovine serum albumin (BSA) are responsible for their antitumor activity due to different modes of interaction with DNA and their transport through the blood system to cells and tissues via serum albumin. Therefore, the dinuclear palladium(II) complexes, [{Pd(en)Cl}2(μ-1,5- nphe)](NO3)2 (<bold>Pd1</bold>) and [{Pd(1,3-pd)Cl}2(μ-1,5-nphe)](NO3)2 (<bold>Pd2</bold>) (en is ethylenediamine, 1,3-pd is 1,3-propylenediamine and 1,5-nphe is the bridging 1,5-naphthyridine ligand) were synthesized and characterized by different spectroscopic methods.

The fluorescence intensity showes that Pd1 and Pd2 complexes can bind to BSA and then be transported to the cell.
