Occurrence of antibacterial and antimycobacterial resistance stimulated a thrust to discover new drugs for infectious diseases. Herein we report the work on re-engineering nalidixic acid’s chemical scaffold for newer leads. Stepwise clubbing of quinoxaline, 1,2,4-triazole/1,3,4-oxadiazole with nalidixic acid yielded better compounds. Compounds were screened against ciprofloxacin resistant bacteria
抗菌和抗分枝杆菌耐药性的出现刺激了人们发现传染病新药的努力。在这里,我们报告了重新设计萘啶酸的化学支架以用于新的潜在客户的工作。喹喔啉,1,2,4-三唑/ 1,3,4-恶二唑与萘啶酸的逐步混合产生了更好的化合物。筛选化合物对环丙沙星抗性细菌和结核分枝杆菌ħ 37器Rv物种。获得了最低抑菌浓度的结果,很明显,以喹喔啉连接的叠氮化物为侧链的分子可作为抗结核铅(<6.25μg/ ml),而以恶二唑或三唑连接的喹喔啉侧链的分子可作为抗细菌铅。很少有化合物对大肠埃希氏菌和寻常变形杆菌具有显着活性,MIC小于0.06μg/ ml,且比环丙沙星相对有效。与阿莫西林相比,没有真正的化合物对沙门氏菌具有潜在的活性。
