Résumé: | New Palladium (II) complexes with a series of iminocoumarin derivatives have been synthesized and charac-
terized by analytical analysis, spectral methods, magnetic measurements and thermal studies. The experimental
results indicated that the Pd(II) complexes are coordinated to the bidentate iminocoumarin derivatives with a
distorted square planar geometry. The DFT calculations were performed in order to optimize the geometric
structures, to calculate structural parameters and to explain the chemical reactivity of the synthesized com-
pounds. Electrochemical behaviour of the synthesized compounds was studied by cyclic voltammetry. The
antioxidant activity of free ligands and their Pd(II) complexes have been evaluated using the DPPH method. The
antimicrobial activity was also evaluated in Vitro against two Gram-negative (E. coli, Klebsiella pneumonia), two
gram-positive (Staphylococcus aureus, Enterococcus faecalis) and three fungal strains (Candida albicans, Candida
tropicalis and Aspergillus niger) using the agar-diffusion method. The ADMET study was also accomplished in
order to predict pharmacokinetic and toxicity of the synthesized compounds. Finaly, and in order to study the
molecular interaction of the ligand L3 and its corresponding Pd(II) complex with the microbial enzymes; Docking
studies were employed |
