Abstract
Platinum-based anticancer drugs are among the most widely used antineoplastics in clinical settings. Their therapeutic applications and outcomes are, however, greatly hampered by drug resistance, systemic toxicity, and the lack...

New monofunctional platinum(II) and palladium(II) complexes: Studies of the nucleophilic substitution reactions, DNA/BSA interaction, and cytotoxic activity. J Inorg Biochem 2018; 189:91-102. [PMID: 30243122 DOI: 10.1016/j.jinorgbio.2018.09.005] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 08/28/2018] [Accepted: 09/09/2018] [Indexed: 01/22/2023]
Abstract
Four new complexes [Pd(H2LtBu)Cl]Cl (Pd1), [Pt(H2LtBu)Cl]Cl (Pt1), [Pd(Me2LtBu)Cl]Cl (Pd2) and [Pt(Me2LtBu)Cl]Cl (Pt2) (where H2LtBu = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine and Me2LtBu = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine) were synthesized and characterized by elemental microanalysis, IR, 1H NMR and ESI-MS methods. The reactivity of complexes towards thiourea (Tu), l-methionine (l-Met), l-cysteine (l-Cys) and guanosine-5'-monophosphate (5'-GMP) was investigated. The obtained order was established as follows: Tu > l-Cys > l-Met > 5'-GMP. Complexes Pd1 and Pt1, that contain H2LtBu as chelator, showed higher reactivity towards biomolecules than those with Me2LtBu. The interaction of complexes with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) was studied by UV-Vis and fluorescence spectroscopy. The results have shown that complexes can bind to DNA exhibiting high binding constants (Kb = 104 M-1). Obtained results during the examination of competitive reaction with ethidium bromide (EB) showed that complexes can replace EB-bound DNA. High values of binding constants indicate good binding affinity of complexes towards BSA. We evaluated the stability differences between complexes based on terpy as well as H2LtBu/Me2LtBu by DFT calculations (B3LYP(CPCM)/LANL2DZp), showing that both tridentate ligand systems lead to complexes of similar stability. The results of biological testing showed that all complexes exert moderate to high selective cytotoxicity, inducing apoptosis and autophagy in HeLa and PANC-1 tumor cell lines. Pd1 exhibited the strongest cytotoxic effect. Finally, cell cycle analysis showed that in HeLa cells Pd1, Pd2 and Pt1 induced accumulation of cells in S phase, whereas in PANC-1 cells Pd2 and Pt1 induced G2/M cycle arrest and Pd1 induced G0/G1 arrest.
