Based on the multi-target drug design and hybrid strategy for drug research and development, seven new 3-arylfuran-2(5H)-one-fluoroquinolone hybrids have been designed and synthesized, in which the 3-aryl-4-(2-morpholino- ethoxy)furan-2(5H)-one (targeting tyrosyl-tRNA synthetase, TyrRS) and fluoroquinolone (targeting DNA gyrase) were merged. In the antibacterial assay, most of the tested compounds displayed a broad spectrum of activity against microorganisms including Gram-negative bacteria, Gram-positive bacteria and fungi. Furthermore, the enzyme assay and molecular docking revealed that 3-arylfuran-2(5H)-one-fluoroquinolone is a potent antibacterial agent by disturbing the processes of bacterial DNA replication and protein synthesis. These excellent results strongly suggest that 3-arylfuran-2(5H)-one-fluoroquinolone hybrid deserves to further research as a novel antibiotic.
