Gatifloxacin isomers, [1-cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-7-(2-methyl-1-piperazinyl)-4-oxo-3-quinoline carboxylic acid] and a series of its derivatives were designed and synthesized and evaluated for their in vitro antibacterial activities. Preliminary results indicated that the tested compounds GI1, GI2, GI3 and GI4 demonstrated excellent activity against Staph. epidermidis. In addition, compounds GI1, GI3 and GI4 show MIC 0.015 μg/mL against Klebsiella peneumoniae. It is worth noting that compound GI2 has been found to exhibit the most prominent activity against all of the tested stains. On the basis of these promising results, some tested compounds could be selected as potential drugs candidate for further evaluation.
设计并合成了加替沙星异构体[1-环丙基-6-氟-1,4-二氢-8-甲氧基-7-(2-甲基-1-哌嗪基)-4-氧代-3-喹啉羧酸]及其一系列衍生物,并对其体外抗菌活性进行了评估。初步结果表明,受试化合物 GI1、GI2、GI3 和 GI4 对表皮葡萄球菌具有很好的活性。此外,化合物 GI1、GI3 和 GI4 对肺炎克雷伯菌的 MIC 值为 0.015 μg/mL。值得注意的是,化合物 GI2 对所有测试污渍都表现出了最突出的活性。基于这些有希望的结果,一些测试化合物可被选为潜在的候选药物进行进一步评估。
