furnish novel 7-methoxy pyrrolo[1,2-a]quinoline derivatives (4a-n). All these newly synthesized intermediate products and final compounds have been characterized by spectroscopic techniques such as 1H NMR, 13C NMR, HRMS, and FT-IR. The intermediate ylides and final pyrrolo[1,2-a]quinoline analogues were evaluated for their antitubercular potential against the Mtb H37Rv strain (ATCC 27294). All the tested
通过杂环融合方法设计了一系列新的吡咯并[1,2- a ]喹啉类似物 ( 4a-n ) 用于抗结核评估。目标化合物由6-甲氧基喹啉与不同取代的苯甲酰溴反应得到喹啉叶立德中间体( 2a-i ),再与缺电子乙炔发生[3+2]环加成反应得到新型7-甲氧基吡咯并[1,2- a ]喹啉衍生物 ( 4a-n )。所有这些新合成的中间产物和最终化合物都已通过1 H NMR、13等光谱技术进行了表征C NMR、HRMS 和 FT-IR。评估了中间体叶立德和最终的吡咯并[1,2- a ]喹啉类似物对Mtb H37Rv 菌株 (ATCC 27294) 的抗结核潜力。与标准药物异烟肼 (0.195 µM=0.026 µg/mL) 相比,所有测试化合物均表现出抗结核活性,MIC 99在 25–50 µM (10.4–25.7 µg/mL) 范围内。计算机分子对接研究揭示了目标化合物与酶Mtb CYP 121的强结合
