According to substructure link principle, a series of novel phosphonate derivatives bearing quinolinone moiety were designed and synthesized. The structures of the products were confirmed by IR, 1H NMR and MS data. The antibacterial activities of the products against S. aureus, E.coli, drug-resistant S. aureus were evaluated by the agar dilution method. The results demonstrated that some compound exhibited superior activities against drug-resistant S. aureus compared with norfloxacin. Especially, compound Ⅲk showed more potent activities against MRSA15# with minimum inhibitory concentration (MIC) values of 6.2 mg/mL, and against QRSA7# with MIC values of 3.1 mg/mL.
Key words: quinolinone; α-aminophosphonate; amide; synthesis; antibacterial activity
