  Design, Synthesis, and Evaluation of Novel Fluoroquinolone−Aminoglycoside Hybrid Antibiotics

  摘要：

  A series of new hybrid structures containing fluoroquinolone (ciprofloxacin) and aminoglycoside (neomycin) antibiotics linked via 1,2,3-triazole moiety were designed and synthesized, and their antibacterial activities were determined against both Gram-negative and Gram-positive bacteria, including resistant strains. The nature of spacers in both the ciprofloxacin and neomycin parts greatly influenced the antibacterial activity. The majority of hybrids was significantly more potent than the parent neomycin and overcame most prevalent types of resistance associated with aminoglycosides. Selected hybrids inhibited bacterial protein synthesis with the potencies similar to or better than that of neomycin and were up to 32-fold more potent inhibitors than ciprofloxacin for the fluoroquinolone targets, DNA gyrase and toposiomerase IV, indicating a balanced dual mode of action. Significant delay of resistance formation was observed in both E. coli and B. subtilis to the treatment with ciprofloxacin-neomycin hybrid in comparison to that of each drug separately or their 1: 1 mixture.

  Provided herein are antimicrobial conjugates of two antibiotic agents, exhibiting improved activity also against resistant bacteria, compared to each of the agents separately or their mixture, and having substantially no resistance emerged thereagainst, as well as processes for preparation the same, compositions containing the same, and uses thereof in medical treatments against pathogenic microorganisms. The disclosed antimicrobial conjugates are composed of aminoglycosides and non-ribosomal active antibiotics. Some of the antimicrobial conjugates are prepared via "click" chemistry.
