Background: Oximes and nitrofuranyl derivatives are particularly important compounds in medicinal chemistry. Thus, many researchers have been reported to possess antibacterial, antiparasitic, insecticidal and fungicidal activities. Methods: In this work, we report the synthesis and the biological activity against Mycobacterium tuberculosis H37RV of a series of fifty aryl oximes, ArCH=N-OH, I, and eight
背景:肟和硝基呋喃基衍生物是药物化学中特别重要的化合物。因此,据报道,许多研究人员具有抗菌、抗寄生虫、杀虫和杀真菌活性。方法:在这项工作中,我们报告了一系列五十种芳基肟 ArCH=N-OH, I 和八种硝基呋喃基化合物 2-硝基呋喃基-X, II 的合成和抗结核分枝杆菌 H37RV 的生物活性。结果:在肟中,I:Ar = 2-OH-4-OH,42 和 I:Ar = 5-硝基呋喃基,46,分别在 3.74 和 32.0 µM 处具有最佳活性。还有,46,硝基呋喃化合物,II;X = MeO,55 和 II:X = NHCH2Ph,58,(分别为 14.6 和 12.6 µM),表现出优异的生物活性并且无细胞毒性。结论:化合物55显示出9.85的选择性指数。使用化合物 55 进行了进一步的抗菌测试,该化合物对粪肠球菌、肺炎克雷伯菌、铜绿假单胞菌、金黄色葡萄球菌、鼠伤寒沙门氏菌和福氏志贺氏菌无活
