Anticancer potential of metal thiosemicarbazone complexes: A review
Thiosemicarbazones are Schiff based ligands which have gained importance over the decades as potential drug candidates. When coordinated to metals, they have proved as good anticancer, antimicrobial, antioxidant and antiprotozoal agents. Numerous applications of these ligands in the field of Analytical Chemistry have also been reported. The present review aims to summarize some of the recent ad...
متن کاملSynthesis, Spectral, and Biological Properties of Copper(II) Complexes of Thiosemicarbazones of Schiff Bases Derived from 4-Aminoantipyrine and Aromatic Aldehydes
We have synthesized a novel series of Schiff bases by condensation of 4-aminoantipyrine and various aromatic aldehydes followed by reaction with thiosemicarbazide. These thiosemicarbazones are potential ligands toward transition metal ions. The reaction of copper(II) salts with 4[N-(benzalidene)amino]antipyrinethiosemicarbazone (BAAPTS), 4[N-(4'-methoxybenzalidene) amino] antipyrinethiosemicarb...
متن کاملThiosemicarbazone Metal Complexes: From Structure to Activity
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.
متن کاملSTUDY ON THE COMPLEX FORMATION BETWEEN N-PROPYLSALICYLIDENE BASED ON SILICA AS ION EXCHANGER AND SOME TRANSITION METAL IONS
N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...

Transition metal complexes of thiosemicarbazones have generated considerable interest due to their wide ranging biological activities. Zinc II complexes with thiosemicarbazone ligands were reported to posses antiproliferative, antitumor and antimicrobial activities. In this work, zinc (II) complex of 2-acetylbenzothiophene 3-thiosemicarbazone [Zn(BTTS)2] has been prepared by condensation of zin...
