  6-氨基喹诺酮类：一类新的喹诺酮类抗菌剂？

  摘要：

  通过先前的QSAR研究设计了一系列喹诺酮和1,8-萘啶酮-3-羧酸，它们的特征是在C-6位置的氨基而不是通常的氟原子，并进行了首次体外抗菌活性。所有合成的化合物都对革兰氏阴性菌保持良好的活性（铜绿假单胞菌除外），并且具有硫吗啉基作为C-7取代基的那些化合物也对革兰氏阳性菌具有良好的活性。还讨论了与C-1，C-5，C-7和C-8取代基相关的结构活性关系的某些方面。衍生物18g和38g对革兰氏阴性菌和革兰氏阳性菌分别具有0.45和0.66-0.76微克/ mL的几何平均MIC的最佳活性。这种抗菌活性反映了它们抑制细菌DNA旋转酶的能力。这项研究的结果表明，尽管C-6氟仍然是优选的取代基，但仍可通过用氨基取代而获得良好的活性。

  New 6-nitroquinolones: synthesis and antimicrobial activities

  摘要：

  Pursuing our searches on quinolonecarboxylic acids we used a simple three-step one pot procedure to synthesize novel 1,7-disubstituted-6-nitroquinolones. The new derivatives were tested against Mycobacterium tuberculosis and Mycobacterium avium complex (MAC) as well as against both gram-positive and gram-negative bacteria. In vitro assays showed some derivatives were endowed with good inhibiting activities against tested mycobacteria. Some derivatives were also found more potent than ciprofloxacin and ofloxacin (used as reference drugs) against gram-positive bacteria.

  During search on quinolonecarboxylic acids we used a facile, convenient two- or three-step procedure to synthesize new quinolone analogs, bearing at the C-7 position alkylamino substituents, and at the C-6 position a fluorine or alternatively a nitro group. The new derivatives were tested against both Gram-positive and Gram-negative bacteria and against a number of different mycobacteria. In vitro assay's showed 1-tert-butyl-7-tert-butylamino-6-nitro-1,4-dihydro-4-quinolone-3-carboxylic acid to be a potent inhibitor of Streptococcus and Staphylococcus with potencies superior to those of ofloxacin and ciprofloxacin, used as reference drugs. Some 6-nitroquinolones were found to exert good inhibiting activities against Mycobacterium tuberculosis and various atypical mycobacteria, whereas the 6-fluoro counterparts showed poor or no activity against this bacterium.

  acids, designed by previous QSAR studies and characterized by an amino group at the C-6 position instead of the usual fluorine atom, were synthesized for the first time and evaluated for in vitro antibacterial activity. All of the synthesized compounds maintain good activity against Gram-negative bacteria (Pseudomonas aeruginosa excluded), and those compounds having a thiomorpholine group as the C-7 substituent
