A novel series of 7-(1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-7-yl) quinolones has been designed and synthesized in which the heterocyclic side chain is attached to the quinolone core through a carbon–carbon linkage. The antibacterial activity of the compounds was determined against a panel of Gram-positive and Gram-negative pathogens. Compounds 1b and 1e, bearing an 8-methoxy group as well as unsubstituted
设计并合成了一系列新颖的7-(1,2,3,4-四氢吡咯并[1,2- a ]吡嗪-7-基)喹诺酮,其中杂环侧链通过碳原子连接到喹诺酮核上–碳链。确定化合物对一组革兰氏阳性和革兰氏阴性病原体的抗菌活性。显示了分别带有8-甲氧基以及未取代的和(3S)-甲基取代的1,2,3,4-四氢吡咯并[1,2 - a ]吡嗪-7-基侧链的化合物1b和1e对耐环丙沙星的肺炎链球菌临床分离株具有显着活性。
