2015): Crystal structures, spectroscopic, electrochemical and antibacterial properties of a series of new copper(II) Schiff base complexes, Journal of Coordination Chemistry, Two new and two previously reported Schiff base ligands as well as four corresponding newCu(II) complexes (CuL 1-4 ) were synthesized and characterized. The Schiff base ligands were synthesized from condensation of 5-bromo-2-hydroxy-3-nitrobenzaldehyde with aliphatic (H 2 L 1-2 ) or aromatic (H 2 L 3-4 ) diamines. Crystal structures of CuL 2 and CuL 3 were determined by X-ray crystallography. Antibacterial properties of these ligands and complexes were studied against four human pathogenic bacteria. The complexes showed moderate antibacterial activities, higher than those of the ligands.

“…These signals were eliminated from IR spectra of the complexes which confirmed the loss of the phenolic protons and the L 2-nature of the ligands in these complexes. The signals at 1500 cm -1 were also assigned to the NO 2 unsymmetrical stretches[27][28][29]. Electronic spectra of the ligands from the aliphatic amines, i.e.…”

We have prepared supramolecular systems of chiral Schiff base Ni(II), Cu(II), Zn(II) complexes and colloidal gold nanoparticles (AuNP) of 10 nm diameters. They demonstrated that direct adsorption of chiral Schiff base metal complex on the surface of AuNP owing to observation of clear induced CD spectra for the first time. We observed and discussed induced CD bands on AuNP from chiral Schiff base Ni(II), Cu(II), Zn(II) complexes.

“…We have previously synthesized and characterized different transition metal complexes of salen-type Schiff base ligands, especially those derived from meso-1,2-diphenyl-1,2-ethylenediamine and have studied their catalytic and biological properties [20][21][22][23][24][25][26][27][28][29][30]. In continuation of our previous studies, we report the synthesis and characterization of four new Mn(III) complexes with Schiff bases of general formula [MnClL x ] (x = 1-4).…”

Four new manganese(III) Schiff base complexes (1-4) were synthesized and characterized. The complexes have general formula [MnClL x ] in which L represents a Schiff base ligand derived from condensation of meso-1,2-diphenyl-1,2-ethylenediamine with salicylaldehyde or its 3-OMe-, 5-Br-or 5-OMe-derivatives (x = 1-4, respectively). The crystal structure of [MnClL 1 ](1) was characterized by X-ray crystallography. The in vitro anticancer activity of these complexes was evaluated by MTT and apoptosis assays against human breast (MCF-7) and liver (Hep G2) cancer cells. The complexes exhibited considerable antiproliferative activity against both cell lines (IC 50 = 10.8-21.02 µM) comparable to cis-platin, except 4 (MCF-7). The highest activity was found for 1 with IC 50 values of 13.62 µM (MCF-7) and 10.8 µM (Hep G2). Flow cytometry experiments showed that 1 induced apoptosis on MCF-7 tumor cell line. Docking simulations using AUTODOCK were also carried out. The results showed that all complexes fitted into the minor groove region of DNA.
