In an attempt to find new bio-active molecules, a series of compounds N-(4-(2-chloroquinolin-3-yl)-6-(aryl)pyrimidin-2-yl)-2-morpholinoacetamides (5a–l) were synthesized by multistep reactions. Compounds were characterized by IR, NMR and mass spectra. Antimicrobial screening of title compounds (5a–l) was carried out against Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and fungi (Candida albicans, Aspergillus niger, Aspergillus clavatus) using serial broth dilution method. On the basis of statistical analysis, it is observed that these compounds gave significant co-relation. Newly synthesized compounds 5e, 5f, 5g, 5i and 5l showed significant potency against different microbial strains.
为了寻找新的生物活性分子,合成了一系列化合物N-(4-(2-氯喹啉-3-基)-6-(芳基)吡咪啶-2-基)-2-吗啉乙酰胺(5a–l),该过程采用了多步反应。化合物通过红外光谱(IR)、核磁共振(NMR)和质谱进行表征。对标题化合物(5a–l)进行了抗微生物筛选,测试对象包括革兰阳性细菌(葡萄球菌、化脓性链球菌)、革兰阴性细菌(大肠杆菌、铜绿假单胞菌)以及真菌(白色念珠菌、黑曲霉和克拉维斯曲霉),采用系列肉汤稀释法。在统计分析的基础上,观察到这些化合物之间存在显著的相关性。新合成的化合物5e、5f、5g、5i和5l对不同微生物株表现出显著的效力。
