A new series of novel 6-(1H-benz[d]imidazol-2-yl)-8-(5-nitro-2-furyl)-3-(4-pyridyl)-7,8-dihydro[1,2,4]triazolo[3,4-b][1,3,4]thiadiazepines 8a—d has been synthesized. These compounds were evaluated for their efficiency as antibacterial agents against two Gram-positive and Gram-negative strains of bacteria along with antifungal activity against two fungal organisms. The antibacterial and antifungal activities of the present compounds were not comparable with those of the standard drugs employed. But, however, all the test compounds could exhibit notable activities only at higher concentrations (250, 500 μg/ml). The chemical structures of these compounds were confirmed on the basis of spectral data.
一系列新型6-(1H-苯并[d]咪唑-2-基)-8-(5-硝基-2-呋喃基)-3-(4-吡啶基)-7,8-二氢[1,2 ,4]三唑并[3,4-b][1,3,4]噻二氮卓8a-d已合成。评估了这些化合物作为针对两种革兰氏阳性和革兰氏阴性细菌菌株的抗菌剂的效率以及针对两种真菌生物体的抗真菌活性。本发明化合物的抗菌和抗真菌活性与所使用的标准药物不可比。但是,所有测试化合物只有在较高浓度(250、500 μg/ml)下才能表现出显着的活性。这些化合物的化学结构根据光谱数据得到确认。
