摘　　要：根据活性结构拼合原理,设计合成了一系列新型喹啉酮类膦酸酯衍生物,其结构经IR,1H NMR,MS及元素分析确认.采用两倍稀释法测试目标化合物对金黄色葡萄球菌、大肠埃希菌、耐甲氧西林金葡菌、耐喹诺酮金葡菌的抑制活性,结果表明:部分目标化合物对耐药菌的抑制作用略优于对照药诺氟沙星,尤以化合物IIIk最好,对MRSA15#,QRSA7#的最小抑菌浓度(MIC)值分别为6.2,3.1 mg/mL.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 nor- floxacin. Especially, compound lllk 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. 1mg/mL.
