Background: A new series of substituted 1,2,4-triazoles derivative were synthesized and characterized by IR, 1HNMR, 13CNMR spectra, mass spectroscopy and elemental analysis. Methods: The isonicotinic acid hydrazide (INH) was used as starting material. These synthesized compounds were screened for antitubercular activities by Luciferase Reporter Phase (LRP) assay against drug sensitive reference strain
背景:合成了一系列新的取代的1,2,4-三唑衍生物,并通过IR,1HNMR,13CNMR光谱,质谱和元素分析对其进行了表征。 方法:以异烟酸酰肼(INH)为起始原料。通过针对药物敏感参考菌株(H37RV)以及对S,H,R和E耐药的结核分枝杆菌(MDR)临床分离株的荧光素酶报告基因阶段(LRP)分析,筛选了这些合成的化合物的抗结核活性。一线药物利福平和异烟肼用作标准药物。 结果:研究表明,除化合物5b和5q外,所有筛选出的化合物均显示出良好至中等的活性。 结论:抗结核活性表明,与异烟肼和利福平相比,1,2,4-三唑第三和第四位基团的取代增强了该活性。
