Synthesis and Antibacterial Activity of Nitroaryl Thiadiazole-Levofloxacin Hybrids

Novel levofloxacin‐containing hybrids carrying a 5‐(nitroaryl)‐1,3,4‐thiadiazol‐2‐yl group were synthesized and evaluated in vitro against Gram‐positive and Gram‐negative bacteria. Preliminary data indicated that levofloxacin‐nitrofuran and levofloxacin‐nitroimidazole hybrids have a potent activity...

Zusammenfassung:	Novel levofloxacin‐containing hybrids carrying a 5‐(nitroaryl)‐1,3,4‐thiadiazol‐2‐yl group were synthesized and evaluated in vitro against Gram‐positive and Gram‐negative bacteria. Preliminary data indicated that levofloxacin‐nitrofuran and levofloxacin‐nitroimidazole hybrids have a potent activity against Gram‐positive organisms with enhanced anti‐staphylococcal activity compared with the parent quinolone (N‐desmethyl levofloxacin).
