“…In the case of the Co(II) complexes, the coordinated H 2 O molecules were identified by broad OH absorptions bands around 3510 -3210 cm -1 which keep their intensity even after heating at 110°C for 24 h. Compounds containing the Co(DH) 2 unit, where DH is the mono-anion of dimethylglyoxime, such as vic-dioxime, make up the bulk of a class of compounds known as cobaloximes, which contain two monodeprotonated dioxime ligands H-bonded to each other, with the results that the 4-nitrogen donor atoms are nearly co-planar. [6,13,14] Magnetic Measurements [15] The two water molecules in the Co(II) complexes are in trans position.…”

In this study, six new unsymmetrical vic-dioximes, N-(3,4-dimethylphenyl)aminomethylglyoxime (L 1 H 2 ), N-(3-chloro-4-methylphenyl)aminomethyl-glyoxime (L 2 H 2 ), N-(2,6-dimethylphenyl)aminomethylglyoxime (L 3 H 2 ), N-(3,4-dimethylphenyl)aminophenylglyoxime (L 4 H 2 ), N-(3-chloro-4-methylphenyl)-aminophenylglyoxime (L 5 H 2 ) and N-(2,6dimethylphenyl)aminophenylglyoxime (L 6 H 2 ) have been synthesized from chloromethylglyoxime or chlorophenylglyoxime and the corresponding substituted aromatic amines. The Co(II), Ni(II) and Cu(II) complexes of these ligands were prepared. The structures of these new ligands and their complexes are proposed based upon IR, UV-Vis, 1 H NMR spectral data, magnetic measurements, and elemental analyses.

“…[48] The chemical shift values attributable to the (N OH) protons of the oxime ligand are in good agreement with other previously reported oxime protons. [49][50][51][52][53] The disappearance of these signals upon the addition of D 2 O is evidence that they are assignable to OH protons. The signals at 3.32, 2.28, and 1.79-1.92 ppm were assignable to the CH 3 the CH 2 -piperazine and the aliphatic CH 2 protons, respectively.…”

The newly synthesized Schiff base‐oxime ligand, namely, (2Z,3E)‐3‐((3‐(4‐(3‐(((2E,3E)‐3‐(hydroxyimino)butan‐2‐ylidene)amino)propyl)piperazin‐1‐yl)propyl)imino)butan‐2‐one oxime (H2L) and its Co (II), Cu (II), and Zn (II) complexes were reported. The characterization was accomplished with the aid of CHN‐EA, mass, fourier transform infrared spectroscopy (FT‐IR), electronic spectra, magnetic moment, molar conductance and TGA. According to the spectroscopic approaches, the synthesized ligand (H2L) may act as a tetradentate or hexadentate (bis‐tridentate) coordinating ligand through the azomethine nitrogen, piperazinyl nitrogens, and oximato‐nitrogens affording distorted square planar mononuclear Co (II) complex or tetrahedrally distorted square planar binuclear Cu (II) and Zn (II) complexes whereas the coordination mode varies according to the nature of the metal ion. The microbial resistance of all the synthesized compounds was evaluated and reported. Findings showed that the Cu (II) complex has mostly the highest inhibitory effects against all tested microbial strains. Besides, the anticancer nature of the studied compounds was also evaluated against a panel of three different human cancer cells, including (HCT‐116), (MDA‐MB‐231), (HepG2) in addition to the (WI‐38) used as a healthy cells. In general, the Cu (II) complex displayed the best cytotoxic profiles against the tested cells than the Co (II) and Zn (II) complexes with negligible toxicity towards the (WI‐38) normal cells. The DNA cleavage activities of all tested compounds were assayed against pBR322 plasmid DNA. Whereas, the Cu (II) complex showed the highest DNA cleavage propensity, which proceeds predominantly via the oxidative mechanism. Additionally, flow cytometric analysis dictates that the Cu (II) complex induces cell cycle arrest in S‐phase and apoptotic cell death on HCT‐116 cells. The morphological transformations distinguished in HCT‐116 cells treated with Cu (II) complex have been depicted with the aid of scanning electron microscopy (SEM). The docking results indicate that the Cu (II) complex strongly interacts with human colon cancer (6GUE), Escherichia coli (3T88), Klebsiella pneumoniae (4HL2), and Staphylococcus aureus (3WQU) proteins, through different modes of interactions that harmonize successfully with the experimental results.
