| dc.description.abstract1 | n the search for new metal complexes with antitumor potential, two dithiocarbazate ligands derived from 1,1,1-trifluoro-2,4-pentanedione (H 2 L 1) and (H2 L2 ) and four Ni(II) complexes, [Ni(L 1 )PPh3 ] (1), [Ni(L 1)Py] (2), [Ni(L2)PPh 3](3), and [Ni(L 2
)Py] (4), were successfully synthesized and investigated by physical-chemistry and spectroscopic methods. The crystal structure of the H2 L 1 and the Ni(II) complexes has been elucidated by single-crystal X-ray diffraction. The obtained structure from H 2 L 1 confirms the cyclization reaction and formation of the pyrazoline derivative. The results showed square planar geometry to the
metal centers, in which dithiocarbazates coordinated by the ONS donor system and a triphenylphosphine or pyridine molecule complete the coordination sphere. Hirshfeld surface analysis by dnorm function was investigated and showed π–π
stacking interactions upon the molecular packing of H 2 L1 and non-classical hydrogen bonds for all compounds. Fingerprint plots showed the main interactions attributed to H·H C·H, O·H, Br·H, and F·H, with contacts contributing between 1.9% and 38.2%. The mass spectrometry data indicated the presence of molecular ions [M + H] + and characteristic fragmentations of the
compounds, which indicated the same behavior of the compounds in solution and solid state. Molecular docking simulations were studied to evaluate the properties and interactions of the free dithiocarbazates and their Ni(II) complexes with selected proteins and DNA. These results were supported by in vitro cytotoxicity assays against four cancer cell lines, showing that the synthesized
metal complexes display promising biological activity. | pt_BR |
