A series of novel substituted N-(3-acetyl-2-oxoquinolin-1(2H)-yl)benzamide (AJQC1-AJQC12) have been synthesized upon refluxing 3-acetyl-1-amino-quinolin-2-one and substituted benzoic acid in the presence of dry redistilled pyridine and silicon tetra chloride as coupling agent. 3-acetyl-1-amino-quinolin-2-one (AJQ1-AJQ12) were synthesized from substituted 3-acetyl coumarin upon refluxing with hydrazine hydrate and ethanol. The structures of the final carboxamide derivatives were confirmed by IR, 1H NMR and mass spectra. The synthesized compounds were screened for their antimicrobial activity by tube dilution method and anti tubercular activity by microplate Alamar blue assay. Most of the compounds have exhibited promising antibacterial, anti fungal and anti tubercular activities.
在干燥的重蒸馏吡啶和作为偶联剂的四氯化硅存在下,将 3-乙酰基-1-氨基-喹啉-2-酮和取代苯甲酸回流,合成了一系列新型取代 N-(3-乙酰基-2-氧代喹啉-1(2H)-基)苯甲酰胺 (AJQC1-AJQC12)。3-acetyl-1-amino-quinolin-2-one (AJQ1-AJQ12) 由取代的 3-acetyl 香豆素与水合肼和乙醇回流合成。最终羧酰胺衍生物的结构通过红外光谱、1H NMR 和质谱得到了证实。采用试管稀释法对合成的化合物进行了抗菌活性筛选,并采用微孔板阿拉玛蓝检测法对其进行了抗结核活性筛选。大多数化合物都表现出了良好的抗菌、抗真菌和抗结核活性。
