The main purpose of the current work is the design and synthesis of new Co(II), Ni(II), and Cu(II) mixed‐ligand complexes derived from simple and easily synthesized azo‐ligand, [2‐(phenylthio)phenyl]diazenyl}‐2‐naphthol (HTe), with 8‐hydroxyquinoline (HQ) to improve and understanding their action as an antimicrobial candidate and their therapeutic efficiency with the aid of density functional theory (DFT) calculations and molecular docking studies, which considered a hot topic of research. To access this target, and to explore the effect of changing metal ion type, the new Co(II), Ni(II), and Cu(II) mixed‐ligand complexes were firstly synthesized and characterized via elemental analysis, Fourier transform infrared (FT‐IR), mass spectrometry, ultraviolet–visible spectroscopy, magnetic susceptibility, thermogravimetric analysis (TGA), and stoichiometry analysis molar ratio method. Upon further inspection, the octahedral structures of the isolated metal complexes were found. The compounds' molecular structures were optimized using the DFT technique, and the quantum chemical parameters were evaluated. To determine whether or not these compounds are effective in preventing the spread of harmful bacteria and fungi, two of the most common environmental pollutants in the Arab world, a disc diffusion test was conducted. The prepared complexes were much more efficient against bacteria than the pristine ligands. Molecular docking experiments helped researchers learn which medicines inhibited the 1fj4 protein. All other tested compounds were found to have lower binding affinities than CuTeQ. This suggests that these compounds have the potential as starting points for the production of new classes of antibiotics. Finally, a correlation of the in vitro activity with the DFT and molecular docking data has been done and discussed.

This work synthesized three new CrAz2, MnAz2, and FeAz2 complexes and investigated them using IR, mass, UV spectroscopy, elemental analysis, conductivity and magnetic tests, and thermogravimetric analysis. The azo-ligand, 4-(2-hydroxyphenylAzo)-1-naphthol (Az), couples with metal ions via its nitrogen (in −NN– bonds) and oxygen (in hydroxyl group) atoms, according to the IR spectra of these complexes. Through thermal examination (TG/TGA), the number and location of water in the complexes were also determined. Density functional theory (DFT) theory is applied to ameliorate the structures of the ligand (Az) and metal complexes and analyze the quantum chemical characteristics of these complexes. The antifungal and antibacterial activity of the ligand and its complexes opposed to several hazardous bacteria and fungi was investigated in vitro. Metal complexes were discovered to have a higher inhibitory impact on some organisms than the free ligand. The MnAz2 complex exhibited the best activity among the studied materials, whereas the CrAz2 complex had the lowest. The compounds’ binding affinity to the E. coli (PDB ID: 1hnj) structure was predicted using molecular docking. Binding energies were calculated by analyzing protein-substrate interactions. These encouraging findings imply that these chemicals may have physiological effects and may be valuable for a variety of medical uses in the future.

Reaction of 1‐(4‐methylquinoline‐2‐yl)hydrazine with Alloxan yielded a new hydrazone ligand (AlloxHQ). Binary copper (II) AlloxHQ complexes have been successfully prepared utilizing different copper (II) salts (chloride, bromide, sulfate, and acetate). Moreover, ternary complexes have been prepared by using secondary ligands; 1,10‐phenanthroline and oxine. The structures of AlloxHQ and Cu (II)‐AlloxHQ complexes have been investigated with the aid of elemental analysis, nuclear magnetic resonance, infrared, electronic, mass, and electron spin resonance spectra, thermal analysis in addition to measurements of molar conductivity and magnetic susceptibility. Mono‐, bi‐, and tri‐nuclear complexes were obtained, reflecting that the coordinating manner of AlloxHQ is extremely influenced by both the nature of the counter anion and the pH of the medium. AlloxHQ acts as a tri‐, bi‐, or penta‐dentate ligand with different modes of bonding. AlloxHQ and its copper (II) complexes exhibited antitumor activity towards Ehrlich Ascites Carcinoma and coordination with copper improved the antitumor activity. The biological activity was confirmed by molecular docking study to investigate how the title compounds bind to the CDK‐5 inhibitor‐crystal structure of inhibitor EFP with CDK‐2 (PDB ID: 3IG7).
