Copper(II) complexes of N,N'-disubstituted thioureas as antimicrobial agents: design, synthesis, biological evaluation, and computational studies. In the present study, six copper(II) complexes, [Cu(en)(2)][Cl(2)], [Cu(pcta)(2)][Cl(2)], [Cu(pcta)(2)][OH(2)], [Cu(pcta)(2)][Cl], [Cu(pcta)(2)][BF(4)], [Cu(pcta)(2)][NO(3)] were synthesized by using the hydrothermal method. All of them contain an octahedral Cu(II) ion surrounded by two nitrogen and two sulfur atoms from the coordinated en and pcta ligands. The structures of [Cu(en)(2)][Cl(2)] and [Cu(pcta)(2)][NO(3)] were characterized by single crystal X-ray diffraction. Their antibacterial activity was evaluated against Gram-positive and Gram-negative bacterial strains. Furthermore, their mode of action was investigated by molecular docking studies. The antibacterial activities of the complexes were higher than that of their ligands, indicating that the presence of a metal center does not enhance the antibacterial activity of the free ligands. The antimicrobial assay showed that the complexes [Cu(en)(2)][Cl(2)], [Cu(pcta)(2)][Cl(2)], [Cu(pcta)(2)][OH(2)], [Cu(pcta)(2)][Cl], [Cu(pcta)(2)][BF(4)], and [Cu(pcta)(2)][NO(3)] possessed more potent bactericidal activities than their corresponding ligands. The mode of action investigation revealed that the complexes [Cu(pcta)(2)][Cl(2)] and [Cu(pcta)(2)][NO(3)] exhibited multi-target and multi-mechanism of antimicrobial action against both Gram-positive and Gram-negative bacteria. The docking results indicated that the antibacterial activity of the complexes was due to complex
