The metal complexes exhibited stronger activity than free ligands against both cancer and bacteria due to the greater lipophilicity of complexes.

These ligands could coordinate to transition metals through various modes. The paper focuses on the coordination of the thiosemicarbazone Schiff base ligands with nickel, palladium, and platinum metal ions to generate biologically active complexes. Both the ligands and the metals have strong biological properties. So, the most important biological activities, particularly anticancer and antibacterial are considered in the study.
