Synthesis, characterization and urease inhibitory activity of oxovanadium(V) complexes with similar Schiff bases

A series of structurally similar oxovanadium(V) complexes with analogous Schiff bases have been prepared and structurally characterized. The urease inhibitory activities of the complexes were investigated. The shorter the terminal groups of the Schiff base ligands are, the stronger the urease inhibitory activities of the oxovanadium(V) complexes.
