A series of novel 7-(3-alkoxyimino-4-amino-4-methylpiperidin-1-yl)fluoroquinolone derivatives were designed, synthesized and evaluated for their in vitro antibacterial activity and cytotoxicity. All of the target compounds have potent antibacterial activity against the tested Gram-positive and Gram-negative strains, and exhibit good potency in inhibiting the growth of Staphylococcus aureus including
设计,合成和评价了一系列新颖的7-(3-烷氧基亚氨基-4-氨基-4-甲基哌啶-1-基)氟喹诺酮衍生物,并对其体外抗菌活性和细胞毒性进行了评估。所有目标化合物均对测试的革兰氏阳性和革兰氏阴性菌株具有有效的抗菌活性,并在抑制包括MRSA的金黄色葡萄球菌,包括MRSE的表皮葡萄球菌和肺炎链球菌的生长方面表现出良好的效力(MIC:0.125–4μg/毫升)。化合物22对革兰氏阳性菌株的活性最高,对吉肠沙星,加替沙星和左氧氟沙星对粪肠球菌的效力比其高4-16倍分别比左氧氟沙星对表皮葡萄球菌09-6和肺炎链球菌08-4的效力高16倍和4倍。
