NMR and mass spectral studies. The 7-(1-isobutyl-1H-imidazo[4,5-c]quinolin-4-yl)-7-azabicyclo[4.2.0]octa-1,3,5-trien-8-one (8a–f) analogues were evaluated for their in vitro antimicrobial activity by serial dilution method minimum inhibitory concentration (MIC). The derivatives 8c, 8e and 8f exhibited excellent antibacterial activity comparable to the parent drug ampicillin with MIC value. Compounds 7a–f
为了寻找一种基于咪唑并喹啉结构框架的新型高效抗菌剂,一系列新的7-(1-异丁基-1 H-咪唑并[4,5 - c ]喹啉-4-基)-7-氮杂双环[ 4.2.0] octa-1,3,5-trien-8-ones(8a – f)是通过相应的2,4-二氢氧喹啉衍生物经多步反应合成的。这些化合物的结构通过IR,1 H NMR,13 C NMR和质谱研究确定。7-(1-异丁基-1 H-咪唑并[4,5 - c ]喹啉-4-基)-7-氮杂双环[4.2.0] octa-1,3,5-trien-8-one(8a – F通过系列稀释法最小抑菌浓度(MIC)评估类似物的体外抗菌活性。衍生物8c,8e和8f表现出与母体药物氨苄青霉素相比具有优异MIC值的优异抗菌活性。还使用台盼蓝排除法对化合物7a - f和8a - f的抗HeLa细胞杀伤活性(IC 50)进行了评估。化合物7c和8b显示出潜在的抗癌活性。在分子对接
