Özet

In the present work, a newly synthesized silver(I) complex was characterized using elemental analysis, UV-Vis spectroscopy, and infrared spectroscopy. DFT calculations at the B3LYP/LANL2DZ level were used to investigate structural, electronic, and spectroscopic properties. The intermolecular inter-actions in the structure were analyzed by topological AIM, RDG, and NBO approaches. Compound [Ag(4-pyridinecarboxaldehyde)(4)]NO3 proved to be the most active compound in this study and showed the highest antibacterial activity against S. aureus ATCC 29,213 , S. epidermidis ATCC 35,984 and P. aeruginosa ATCC 27,853 . Test compound was examined for antiquorum-sensing activity against C. violaceum ATCC 12,472 and title compound exhibited good antiquorum-sensing activity. In addition, these compound activity relationships were further supported by in-silico molecular docking studies where some of the active title compound showed maximum dock score.
