Abstract

In a present review article, relationships were identified between the structure and activity of the bisthiosemicarbazone ligands and their zinc and copper complexes. These compounds have different substituents at the diimine point and terminal nitrogen of the backbone. All the copper complexes showed distortion in geometry from square planar while all the zinc complexes showed distortion in geometry from square pyramidal. In electrochemistry determination by cyclic voltammetry, all the copper complexes were found quasi-reversible. When the antiproliferative activity was checked against tumor cells, copper complexes showed the greatest activity. It was seen that antiproliferative activity was decreased when hydrophobic moieties were present at diimine points and terminal nitrogen. Zinc complexes showed the lowest antiproliferative activity because they were failed in ligand delivery intracellularly as they were not chaperone. But cobalt showed good activity by successfully delivering the ligand acting as chaperone¹. Copper complexes showed more antiproliferative activity as compared to the ligand. In the environment of the tumor, hypoxia was found which decreased the antiproliferative activity of the ligand and its copper complexes. In the present study, it was concluded that this relationship could be helpful in the synthesis of antitumor agents such as bis-thiosemicarbazone and its complexes.
