6H)‐yl)‐6‐fluoro‐4‐oxo‐1,4‐dihydroquinoline‐3‐carboxylic acid derivatives was designed, synthesized and characterized by 1H‐NMR, MS and HRMS. These fluoroquinolones were evaluated for their in‐vitro antibacterial activity against representative Gram‐positive and Gram‐negative strains. Generally, all of the target compounds display rather weak potency against the tested Gram‐negative strains, but most of them
一系列新型7-(3-氨基吡咯并[3,4-c]吡唑-5(2H,4H,6H)-基)-6-氟-4-氧代-1,4-二氢喹啉-3-羧酸衍生物通过 1H-NMR、MS 和 HRMS 设计、合成和表征。评估了这些氟喹诺酮类药物对代表性革兰氏阳性和革兰氏阴性菌株的体外抗菌活性。一般而言,所有目标化合物对受试革兰氏阴性菌株均表现出较弱的效力,但大多数对包括耐甲氧西林金黄色葡萄球菌(MRSA)和包括耐甲氧西林的表皮葡萄球菌在内的金黄色葡萄球菌的生长表现出良好的抑制作用表皮葡萄球菌 (MRSE) (MIC: 0.125-8 µg/mL)。特别是,化合物 9g 比吉米沙星 (GM)、莫西沙星 (MX)、加替沙星 (GT) 和左氧氟沙星 (LV) 对金黄色葡萄球菌的效力高 2 至 32 倍。
