Synthesis and cytotoxicity studies of new 1,2,4-thiadiazole derivatives and their zinc complexes

A new polyfunctional ligand of the thiadiazole family was synthesized. Cytotoxic properties with respect to leukemic cell lines, radiation stability, predicted permeability through the blood–brain barrier and cardiotoxicity of the new ligand and its precursor were determined. New zinc complexes with N-{2-[5-(3-chloro-4-methylphenylamino)-1,2,4-thiadiazol-3-yl]-1-methylethyl}-N-(2,2,6,6-tetramethylpiperidin-4-yl)-amine as the ligand have been obtained.
