Infections are common postoperative complications associated with the use of medical implants such as ureteric double-J stents. However, bacterial resistance to antibiotics poses serious risks to human health. These complications highlight the need for novel antibacterial agents. This study aimed to synthesize ionic liquids (ILs) with antibacterial potential, namely, 1-benzyl-3-(2-nitrobenzoyl)-1 H-imidazol-3-ium chloride (OM-1) and 4-(dimethyl amino)-1-(4-nitrobenzoyl) pyridin-1-ium chloride (OM-2), for use as biocompatible coating materials on double-J stents. The chemical structures of the synthesized ILs were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FTIR) spectroscopy. The antibacterial properties were evaluated using the Kirby-Bauer Disk Diffusion method on Klebsiella pneumoniae and Escherichia coli. Cytotoxicity was evaluated in a human skin fibroblast cell line (HFF-1) using a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2 H tetrazolium (MTS) assay. Molecular docking and ADMETox analyses were also performed to calculate binding affinities and pharmacokinetic properties. At 50 mu g/mL, OM-1 and OM-2 exhibited significant activity against Klebsiella pneumoniae (p = 0.04), with OM-1 differing significantly from Gentamicin (p = 0.017). In Escherichia coli, both ILs exhibited significant differences compared to piperacillin/tazobactam (p < 0.001 and p = 0.002, respectively). At 100
