| Abstract | |
In this study, we report the synthesis and characterization of eight new palladium complexes and a nickel complex containing thiosemicarbazone ligands derived from chalcones and benzalketones. The techniques of Infrared and UV-visible spectroscopy, Nuclear Magnetic Resonance, Mass Spectrometry, and Elemental Analysis fully characterized the compounds. Crystallography was successful for five complexes and two ligands, allowing for X-ray Diffraction analysis. Molecular docking studies and assays involving DNA interaction via agarose gel electrophoresis and UV-Vis titration revealed no DNA interaction or inhibition of topoisomerase II alpha enzyme activity. However, these compounds demonstrated potent cytotoxic effects (IC50) against breast tumor (MCF-7) and prostate (DU-145) cell lines, as well as non-tumor prostate (PNT2) cell lines. These findings highlight the relevance of structural variations and the metallic center's nature in achieving cytotoxic effects, offering insights into the development of bioactive compounds.
