Abstract: © 2019, Society for Biological Inorganic Chemistry (SBIC). Abstract: Three new dinuclear Pd(II) complexes with general formula [{Pd(en)Cl}2(μ-L)](NO3)2 [L is bridging ligand quinoxaline (Pd1), quinazoline (Pd2) and phthalazine (Pd3)] were synthesized and characterized by elemental microanalyses, UV–Vis, IR and NMR (1H and 13C) spectroscopy. The interaction of dinuclear Pd1–Pd3 complexes with calf thymus DNA (CT-DNA) has been monitored by viscosity measurements, UV–Vis and fluorescence emission spectroscopy in aqueous phosphate buffer solution (PBS) at pH 7.40 and 37 °C. In addition, these experimental conditions have been applied to investigate the binding affinities of Pd1–Pd3 complexes to the bovine serum albumin (BSA) by fluorescence emission spectroscopy. In vitro antiproliferative and apoptotic activities of the dinuclear Pd(II) complexes have been tested on colorectal and lung cancer cell lines. All tested Pd(II) complexes had lower cytotoxic effect than cisplatin against colorectal cancer cells, but also had similar or even higher cytotoxicity than cisplatin against lung cancer cells. All complexes induced apoptosis of colorectal and lung cancer cells, while the highest antiproliferative effect exerted Pd2 complex. Graphic abstract: [Figure not available: see fulltext.]
