    Fluoronaphthyridines and quinolones as antibacterial agents. 1. Synthesis and structure-activity relationship of new 1-substituted derivatives
    摘要:
    A series of novel 7-piperazinyl-1-substituted-6-fluoroquinolones and naphthyridines have been prepared and their antibacterial activities evaluated. These derivatives are characterized by having alkyl, alkenyl, arylalkyl, cycloalkyl, and cycloalkenyl groups at the 1-position. As a result of this study, derivatives 7 and 26, which are substituted with tert-butyl groups at N-1, were found to possess excellent in vitro and in vivo potency, particularly against Staphylococcus aureus, comparable to that of norfloxacin or ciprofloxacin. Structure-activity relationships of N-1 substituted alkyls and cycloalkyls are also discussed.

    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。

    then acidified with hydrochloric acid afforded the desired 1-(substituted-benzyl)-6-fluoro-1,4-dihydro-4-oxo-7-(1-iperazinyl)quinoline-3-carboxylic acids. The 6,8-difluoro analogs were prepared similarly using 6,7,8-trifluoro-4-hydroxyquinoline-3-carboxylic acid ethyl ester as a starting material. Some of these quinolones demonstrated fairly good antibacterial activities. Among them, 6-fluoro-1-(4-fluorophenylmethyl)-1

    strains, especially ethoxycarbonyl IDO (0.25–0.5 μg/mL) and hydroxyethyl IDO (0.25–1 μg/mL) exhibited much superior antibacterial efficacies to reference drug norfloxacin. These highly active IDOs also displayed low hemolysis, cytotoxicity and resistance, as well as rapid bactericidal capacity. Further investigations indicated that ethoxycarbonyl IDO and hydroxyethyl IDO could effectively reduce the exopolysaccharide
    细菌对临床沙星的严重耐药性的出现对全球公共卫生构成了相当大的威胁,因此需要开发新型结构抗菌剂。首次以商业 3,4-二氟苯胺为原料,通过八步程序设计并合成了七种新型吲哚丙烯酰衍生的沙星 (IDO)。通过现代光谱技术对合成的化合物进行了表征。评估所有目标分子的抗菌活性。大多数制备的IDO对受试菌株表现出广泛的抗菌谱和较强的活性,特别是乙氧羰基IDO(0.25-0.5μg/mL)和羟乙基IDO(0.25-1μg/mL)表现出比参比药物诺氟沙星更优越的抗菌功效。这些高活性的IDO还表现出低溶血性、细胞毒性和耐药性以及快速杀菌能力。进一步的研究表明,乙氧羰基IDO和羟乙基IDO可以有效降低胞外多糖含量并根除形成的生物膜,从而延缓耐药性的发展。初步探索其抗菌机制发现,活性IDO不仅会破坏膜完整性,导致膜通透性改变,还会促进活性氧的积累,导致丙二醛产生,降低细菌代谢。此外,它们表现出与DNA和DNA旋转
