“…According to our previous synthetic methods, [12,[27][28][29] yellow and orange zinc(II) complexes were obtained ready by stepwise addition of ligand (1 mmol, 0.389 g) to zinc salts (1 mmol, ZnCl 2 (0.136g), ZnBr 2 (0.225 g), ZnI 2 (0.319 g), and fresh prepared solution containing 1mmol Zn(NCS) 2 in ethanol under continuing stirring of reaction mixture up to 2-3 h at room temperature. Recrystallization of zinc complexes were performed in dichloromethane/ ethanol mixture (1:1).…”

“…During this period of time, biological inorganic chemists also tried to apply them as antimicrobial agents. [1,2] Comprehensive studies around the Schiff bases and their complexes, leading to numerous reports in different fields that include synthesis and catalyst, [3,4] magnetic materials, [5] hydrolysis, [6] redox reaction, [7] anticorrosion, [8][9][10][11] and biological application such as antibacterial, [12] antifungal, [13] anticancer, [14] antiviral, [15] antitumor, [16] and many other usages. Schiff base ligands are coordinated to metal ions (with different oxidation numbers) basically via azomethine groups and some other neighbor functional groups afterwards stable Schiff base complexes are formed.…”

An asymmetrical Schiff base ligand with two position for coordination to metal was obtained by condensation reaction between propane-1,2-diamine and (E)-3-(4-(dimethylamino)phenyl)acrylaldehyde. Characterization of the ligand and its Zn(II) complexes were performed suitably by means of the elemental analysis, FTIR, 1 H, 13 C NMR, UV-visible, melting points, and molar conductance. Lowering of the iminic bond energy, red shifts of electronic transition bands, and down fielded azomethine proton signals well confirm coordination of ligand to zinc center. All compounds were stable at room temperature for the many long times. All complexes were suggested to be nonelectrolytes due to low molar conductivities. After characterization, antibacterial properties of all compounds have been studied against two Gram-negative bacteria, Escherichia coli (ATCC 25922) and Pseudomonas aeroginosa (ATCC 9027), and two Gram-positive bacteria, Staphylococcus aureus (ATCC 6538) and Bacillus subtilis. The ligand and Zn(II) coordination compounds demonstrated acceptable antibacterial activities. Zinc complexes showed higher activity than the parental ligand. The compounds inhibited the growth of Gram-negative more efficiently than Gram-positive bacterial strains. MIC and MBC of all compounds as alternative data for antibacterial activity were reported in mg/mL.

A new symmetrical bidentate Schiff base ligand (L) was applied for the synthesis of some new cadmium coordination compounds having the general formula [Cd(L)X 2 ], in which X is a halide or a pseudo-halide. The ligand and all the cadmium complexes were characterized by elemental analysis, FT--IR, 1 H-NMR, 13 C-NMR and UV-Vis spectroscopy and by molar conductance measurements. Electrochemical behavior of ligand and Cd(II) complexes were investigated by the cyclic voltammetry method. The morphology and shape of the [Cd(L)Cl 2 ] particles were depicted by SEM. Antimicrobial properties, such as antibacterial and antifungal activities, of the complexes as compared with ligand were checked against three Gram-negative bacteria: Escherichia coli (ATCC 25922), Pseudomunase aeroginosa (ATCC 9027) and Salmonella Spp. two Gram-positive bacteria: Staphylococcus aureus (ATCC 6538) and Corynebacterium renale and three fungal strains, including Aspergillus niger, Penicillium chrysogenum and Candida albicans. The results revealed appropriate antibacterial and antifungal activities for all compounds, and it was found that coordination of the ligand to Cd(II) lead to an increase in the antimicrobial activities in most of cases.

“…Cadmium(II) derivatives are well known human carcinogens (Maret & Moulis, 2013) and their complexation can lead to lower toxicity. Some Schiff base cadmium complexes were found to be active against Candida albicans (Montazerozohori et al, 2014a(Montazerozohori et al, , 2014b(Montazerozohori et al, , 2015 or Aspergillus niger (Montazerozohori et al, 2014a).…”

Synthesis, characterization, and biological activities of oxovanadium(IV) and cadmium(II) complexes with reduced Schiff bases derived from N,Nʹ-o-phenylenebis(salicylideneimine)

New oxovanadium(IV) and cadmium(II) complexes with reduced Schiff bases derived from N,No-phenylenebis(salicylideneimine) have been synthesized and characterized using infrared and UVvisible spectra, ESR, and thermogravimetry. The complexes were identified as [ML] · (H2O) species, where deprotonated ligands are coordinated to metal through N2O2 donor atoms. Antioxidant activity of the ligands and complexes was evaluated, revealing that the complexes exhibit a higher scavenging activity than the corresponding ligands. The prepared cadmium complexes showed slightly higher activity than the vanadium ones. Antifungal activity was tested against different human fungi including yeasts of the Candida genus (C. albicans and C. glabrata) and an opportunistic mould Aspergillus fumigatus. The oxovanadium complexes exhibited a very low activity toward C. albicans while the cadmium ones showed a significant growth inhibition of all the fungi tested; mainly of A. fumigatus though this mould is poorly susceptible to current antifungal agents like Itraconazole.
