Thiosemicarbazone Metal Complexes: From Structure to Activity
نویسنده
چکیده
Thiosemicarbazones and their metal complexes are compounds that possess antitumor, antibacterial, antifungal and antiviral properties. For the foremost majority of cases the activity of the ligand is greatly enhanced by the presence of a metal ion. The most relevant papers recently published are reviewed with an attempt to find a relationship between common structural features and activity.
