To understand the effects of picolinamide-like ligands on reaction equilibrium, a series of picolinamide derivatives were synthesized and the interactions between the diperoxovanadate complex [OV(O 2 ) 2 L] À (L ¼ D 2 O or HOD, abbr. bpV) and picolinamide ligands in solution were explored using multinuclear ( 1 H, 13 C, and 51 V) magnetic resonance, COSY, and HSQC in 0.15 mol L À1 NaCl ionic medium for mimicking physiological conditions. Formation constants among the picolinamide-like ligands are N-(1-hydroxypropan-2-yl)-picolinamide % N-(2-hydroxypropyl)-picolinamide4N-(3-hydroxypropyl)-picolinamide4N-propyl-picolinamide. The substituting group influences the equilibrium by electronic effects. The interactions result in a series of new seven-coordinate diperoxovanadate species [OV(O 2 ) 2 L 0 ] À (L 0 ¼ picolinamidelike ligands).

“…The antifungal activity of the complexes is less than standard fungicides, namely, cycloheximide, carbendazim, and fluconazole (MIC values 53.12 mg mL À1 ). A comparison of the results of biological activity of the monooxovanadium(V) complexes with that of other reports [45][46][47][48][49][50][51][52][53][54][55] revealed the effectiveness of newly synthesized vanadium complexes as antimicrobial agents.…”

“…The biological activity of several vanadium complexes has been reported [45][46][47][48][49][50][51][52][53][54][55]. The ligand, 2-phenylphenol, and the newly synthesized monooxovanadium(V) complexes All the complexes possess more activity against S. aureus, with an MIC of 6.25-12.5 mg mL À1 , than the MIC shown for E. coli at 12.5-25 mg mL À1 .…”

Monooxovanadium(V)complexes of the composition VOCl 3Àn (L) n (where L ¼ 2-phenylphenoxide ion; n ¼ 1-3) (1-3) have been synthesized in quantitative yields by the reaction of VOCl 3 with 2-phenylphenol in toluene. The characterization of the complexes has been accomplished by elemental analysis, molar conductance measurements, IR, 1 H-NMR, electronic, mass spectral, and thermal studies. The ligands as well as the complexes have been screened for their in vitro antimicrobial activity against the pathogenic bacteria Escherichia coli and Staphylococcus aureus and fungi Candida albicans, Aspergillus niger, and Fusarium oxysporum by a twofold serial dilution. An increase in the biocidal activity was observed for the vanadium complexes. The minimum inhibitory concentration (MIC) values were 6.25-25 mg mL À1 for complexes, relative to that of the free ligand of 25-50 mg mL À1 .

“…The literature contains numerous reports concerned with the antimicrobial activity of ligands and their complexes against pathogenic bacteria and plant pathogenic fungi [36,37]. Hence, in the present work, the precursor VCl 2 (bzac) 2 , ligands and newly synthesised complexes were tested in vitro for their antibacterial activity against E. coli, S. aureus, P. mirabilis, P. aeruginosa, S. epidermidis and S. flexneri.…”
