In the present study we report the synthesis and antibacterial activity of a new series 2-(1-methyl-4-nitro-1H-imidazol-5-ylsulfonyl)-1,3,4-thiadiazoles (6a-c). Compounds6a-cwere testedin vitroby the conventional agar dilution method against a panel of microorganisms including gram-negative and gram-positive bacteria. Compound6bwith 5-(5-nitrofuran-2-yl)-residue on 1,3,4-thiadiazole scaffold have shown promising antibacterial activities against gram-positive bacteria includingStaphylococcus aureus, Staphylococcus epidermidisandBacillus subtilis.
在本研究中,我们报告了一系列新的2-(1-甲基-4-硝基-1H-咪唑-5-基磺酰基)-1,3,4-噻二唑化合物(6a-c)的合成和抗菌活性。化合物6a-c通过常规琼脂稀释法在体外对包括革兰氏阴性和革兰氏阳性细菌在内的一系列微生物进行了测试。其中,1,3,4-噻二唑骨架上带有5-(5-硝基呋喃-2-基)-残基的化合物6b对革兰氏阳性细菌,包括金黄色葡萄球菌、表皮葡萄球菌和枯草杆菌等,表现出了有前途的抗菌活性。
