合成了一系列取代苯并噻唑-N-苯基乙酰胺衍生物,并通过红外光谱、核磁共振氢谱和质谱方法进行了表征。所有合成的化合物对两种革兰氏阳性菌:金黄色葡萄球菌、枯草杆菌;四种革兰氏阴性菌:大肠杆菌、伤寒沙门氏菌、铜绿假单胞菌和肺炎克雷伯菌;以及一种分枝杆菌:结核分枝杆菌进行了抗菌活性筛选。在测试的15种化合物(6a-o)中,三种化合物6e、6l和6m对革兰氏阳性和革兰氏阴性菌株展现了高活性,其最低抑菌浓度(MIC)值在6.25-12.5微克/毫升之间。化合物6e和6l显示出显著的抗结核活性,其最低抑菌浓度为25微克/毫升。
A novel series of substituted benzothiazole-N-phenyl acetamides were synthesized through a feasible scheme and characterized by IR, 1H NMR and mass spectral methods. All the synthesized compounds were screened for antibacterial activity against two, Gram-positive strains: Staphylococcus aureus, Bacillus subtilis; four, Gram-negative strains: Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and Klebsiella pneumonia; and antitubercular activity against mycobacterial strain: Mycobacterium tuberculosis. Among the 15 compounds (6a-o) tested, three compounds 6e, 6l and 6m have demonstrated high potency with MIC values ranges from 6.25-12.5 μg/mL against both Gram-positive and Gram-negative strains. Compounds 6e and 6l displayed remarkable antitubercular activity with MIC value of 25 μg/mL.
