Previous quantitative and qualitative structure-activity studies in antibacterial monosubstituted 1-ethyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acids prompted us to synthesize the 6,7,8-polysubstituted compounds. In this paper, the preparation and antibacterial activity of the 6,7- and 7,8-disubstituted compounds and their derivatives are described. Among these compounds, 1-ethyl-6-fluoro-1,4-di
先前在抗菌单取代的1-乙基-1,4-二氢-4-氧代喹啉3-羧酸中进行的定量和定性结构活性研究促使我们合成了6,7,8-多取代的化合物。在本文中,描述了6,7-和7,8-二取代化合物及其衍生物的制备和抗菌活性。在这些化合物中,1-乙基-6-氟-1,4-二氢-4-氧代-7-(1-哌嗪基)喹啉-3-羧酸(34)具有许多显着的活性,并且比草酸( 84)对抗革兰氏阳性和革兰氏阴性细菌。讨论了构效关系。
