New series of 1-aryl-1,4-dihydro-4-oxo-6-methyl pyridazine-3-carboxylic acid has been synthesized and the structures of the new compounds were established on the basis of 1H-NMR, mass (ES/MS), elemental analysis and IR spectral data. In vitro antibacterial activity (MIC activity) was evaluated and compared with standard drugs ciprofloxacin, sparfloxacin and trovafloxacin. Most of the compounds in the
合成了一系列新的1-芳基-1,4-二氢-4-氧代-6-甲基哒嗪-3-羧酸,并基于1H-NMR,质量(ES / MS),元素分析和红外光谱数据。对体外抗菌活性(MIC活性)进行了评估,并与标准药物环丙沙星,司巴沙星和曲伐沙星进行了比较。该系列中的大多数化合物对革兰氏阳性和革兰氏阴性生物均显示出非常有趣的抗菌活性。在本文中,我们描述了导致鉴定结合新型哒嗪环替代物的抗菌剂的研究。令人欣慰的是,发现最初制备的哒嗪-3-羧酸类似物在体外的抗菌活性接近相应的氟喹诺酮祖细胞。
