A series of indeno[1,2-c]quinoline derivatives were designed, synthesized and evaluated for their anti-tuberculosis (anti-TB) and anti-inflammatory activities. The minimum inhibitory concentration (MIC) of the newly synthesized compound was tested against Mycobacterium tuberculosis H37RV. Among the tested compounds, (E)-N′-[6-(4-hydroxypiperidin-1-yl)-11H-indeno[1,2-c]quinolin-11-ylidene]isonicotino-hydrazide
一系列茚并 [1,2-c] 喹啉衍生物被设计、合成并评估其抗结核 (anti-TB) 和抗炎活性。新合成的化合物的最低抑菌浓度 (MIC) 已针对结核分枝杆菌 H37RV 进行了测试。在测试的化合物中,(E)-N'-[6-(4-hydroxypiperidin-1-yl)-11H-indeno[1,2-c]quinolin-11-ylidene]isoicotino-hydrazide (12) 表现出显着的抗结核分枝杆菌生长的活性(MIC 值为 0.96 μg/mL),其效力与抗结核药物异烟肼 (INH) 大致相同。通过定量构效关系 (QSAR) 分析来分析重要的结构特征,以更好地了解预测抗结核活性的结构决定因素。使用甲酰基-l-甲硫氨酰基-l-亮氨酰-l-苯丙氨酸 (fMLF) 激活的人类中性粒细胞方法,通过超氧阴离子生成和中性粒细胞弹性蛋白酶 (NE) 释放诱导抗炎活性。结果表明,化合物
