The wide variety of biological activity was exhibited by heterocyclic thiosemicarbazaones .In the recent research, more attention was paid to the Schiff bases and their metal complexes for their significant antibacterial and antitumor activity. Previous studies have centred mainly on transition metal complexes of sulfur-containing Schiff bases with pyridine or furan series. However the complexes of sulfur-containing Schiff bases with pyrazine or thiazole series were seldom reported. Our main job was describ...
