Abstract
We designed and synthesized a series of new ciprofloxacin–dithiocarbamate–benzyl hybrids 5a–n as potential antibacterial agents. All of the synthesized compounds were screened for in vitro antibacterial activity against four bacterial strains (Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Pseudomonas aeruginosa). The antibacterial results indicated that some of the synthesized compounds showed remarkable activity, comparable to their parent drug ciprofloxacin. Among the synthesized compounds, the 4-nitro derivative 5n, exhibited the most antibacterial activity against S. aureus, S. epidermidis, and E. coli. The antibacterial activity of this compound against S. aureus and E. coli was twofold higher than that of its parent ciprofloxacin. Molecular modeling of compound 5n was also investigated in the active site of E. coli DNA gyrase.
