Abstract
[Display omitted]
Ampicillin-salicylaldehyde Schiff base along with metallo-derivatives of Cobalt (II), Nickel (II), Copper (II), Europium (III), and Gadolinium (III) was obtained in a pure form. The compounds acquired were described by elemental evaluation, FT-IR, UV–Vis, Fluorescence, 1HNMR, Mass spectra, thermal analysis methods (TGA, DTG, DTA), magnetic susceptibility, ICP, X-ray, and conductivity. The ligand showed N2O2 binding sites for all the complexes except copper, where it showed NO sites. The synthesized complexes had the formula [M(HAS)(H2O)2](X)(H2O)n for divalent transition metals ions and [M(HAS)(H2O)(X)](X)(H2O)n for trivalent lanthanide ions (where X = NO3–or Cl–). The acquired information indicated that the Cobalt and Nickel compounds had an Oh structure while copper showed a square planar shape. The XRD assessment showed that the nanoparticles could conduct the Cu-HAS complex through monoclinic building. The links of the produced metallo-derivatives and DNA were studied using spectrometric titration (UV–Vis) and the fluorescence competition method. The forms and binding attraction forces were evaluated and determined using the Benesi–Hildebrand technique. The energetic lone pair and surface possessions were achieved and reviewed in silico. The disinfectant behaviour was screened by the disc diffusion technique. H2AS and CuHAS showed stronger antimicrobial activity than ampicillin. Docking was performed with the Escherichia coli protein FabH (1HNJ). The acquired binding values were compared and discussed through in vitro studies.
