Various diclofenac acid hydrazones and amides were synthesized and evaluated for in vitro and in vivo antimycobacterial activities against Mycobacterium tuberculosis. Preliminary results indicated that most of the compounds demonstrated better in vitro antimycobacterial activity (MIC: 0.0383-7.53 microM) than diclofenac (MIC: 21.10 microM) and ciprofloxacin (MIC: 9.41 microM). Among the synthesized
合成了各种双氯芬酸和酰胺,并评估了其对结核分枝杆菌的体外和体内抗分枝杆菌活性。初步结果表明,大多数化合物的体外抗分枝杆菌活性(MIC:0.0383-7.53 microM)比双氯芬酸(MIC:21.10 microM)和环丙沙星(MIC:9.41 microM)更好。在合成的化合物中,1-环丙基-6-氟-8-甲氧基-7-[[N4-(2-(2-(2-(2,6-二氯苯基氨基)苯基)乙酰基)-3-甲基] -N1-哌嗪基发现] -4-oxo-1,4-dihydro-3-quinoline羧酸(5d)是体外活性最高的化合物,MIC为0.0383 microM,比一线抗结核药物异烟肼更有效(MIC:0.1822 microM )。在体内动物模型中,5d以2.42和3降低了肺和脾脏组织中的细菌载量。
