The syntheses and spectroscopic characterization of two 1,2,4-triazole-based oxovanadium(V) complexes are reported: 1- [VO2L1]- and 2 [(VOL2)2(OMe)2] (where H2L1 = 3-(2'-hydroxyphenyl)-5-(pyridin-2' '-yl)-1H-1,2,4-triazole, H3L2 = bis-3,5-(2'-hydroxyphenyl)-1H-1,2,4-triazole). The ligand environment (N,N,O vs O,N,O) is found to have a profound influence on the properties and reactivity of the c...

Several oxovanadium(V) complexes have been shown as a potent anticancer agents. In view of the importance of Vanadium complexes a new Vanadium – Morin complex was synthesized and comprehensively characterized. To provide an insight on the mode and affinity of the interaction of these complex with calf thymus (CT) DNA the following experiments were carried out: fluorescence spectroscopy, UV–vis ...

Oxacalix[6]arene vanadium complexes have been employed for the ROP of cyclic esters and ethylene polymerization.

The biochemical activity and morphology of control and streptozotocin-diabetic rat liver Golgi complexes were previously investigated by us under influence of some vanadium [V(IV)] compounds. The effectiveness of these derivatives depends on the kind of complexing ligands. This paper presents the investigation of the effect of bipyridyl, the ligand of a new vanadium compound, tested by us with ...

Vanadium is an ultratrace element present in higher plants, animals, algae, and bacteria. In recent years, vanadium complexes have been studied to be considered as a representative of new class nonplatinum metal anticancer drugs. Nevertheless, the study cell signaling pathways related compounds has scarcely reported on reviewed thus far; this information highly critical for identifying novel ta...

Vanadium is a trace element mainly connected with regulation of insulin metabolism which is particularly important in diabetes. In recent years, organic complexes of vanadium seem to be more interesting than inorganic salts. Nevertheless, the effect of vanadium on lipid metabolism is still a problematic issue; therefore, the main purpose of this study was to investigate the effect of 3 organic ...

Vanadium has potential for use in diabetes therapy. Many investigators have reported toxic effects of inorganic vanadium salts; however, there are few reports on toxic effects of oxovanadium(VO(2+)) complexes. Therefore, we studied VO(2+) toxicity by examining histological changes and measuring the vanadium concentration in the testis after repeated oral administration of bis(1-oxy-2-pyridine-t...
