A series of 5-(4-biphenylyl)-7-aryl[3,4-d] [1,2,3]-benzothiadiazoles were synthesized, characterized by IR, NMR and elemental analysis and evaluated for in vitro antibacterial activity against some Gram-positive and Gram-negative bacteria. The antibacterial data revealed that compounds 7a-j had better activity against tested Gram-positive organisms than the reference ciprofloxacin and norfloxacin.
合成了一系列5-(4-联苯基)-7-芳基[3,4-d] [1,2,3]-苯并噻二唑,并通过红外光谱,核磁共振和元素分析进行了表征,并评价了对某些化合物的体外抗菌活性。革兰氏阳性和革兰氏阴性细菌。抗菌数据表明,与参考环丙沙星和诺氟沙星相比,化合物7a-j对受试革兰氏阳性生物具有更好的活性。但是,这些化合物对革兰氏阴性菌几乎没有活性。化合物7c和7d是对抗革兰氏阳性细菌最有活性的化合物。
