A series of 2,6-disubstituted and 2,5,6-trisubstituted imidazo[2,1-b][1,3,4]thiadiazoles were synthesized, the structures of the compounds were elucidated and screened for antitubercular activity against Mycobacterium tuberculosis H37Rv using the BACTEC 460 radiometric system, antibacterial activity against Escherichia coli and Bacillus cirrhosis, and antifungal activity against Aspergillus niger and
合成了一系列的2,6-二取代和2,5,6-三取代的咪唑并[2,1-b] [1,3,4]噻二唑,阐明了化合物的结构并筛选了针对结核分枝杆菌的抗结核活性。使用BACTEC 460辐射测量系统的H37Rv,具有针对大肠杆菌和肝芽孢杆菌肝硬化的抗菌活性,以及针对黑曲霉和渥曼青霉的抗真菌活性。在测试的化合物中,2-(2-呋喃基)-6-苯基咪唑并[2,1-b] [1,3,4]噻二唑-5-甲醛(6c)和(2-环己基-6-苯基咪唑并[2,1] -b] [1,3,4]噻二唑-5-基)甲醇(7a)表现出最高的(100%)抑制活性。化合物6a,6b,7c和8a在MIC> 6.25 microg / ml的情况下表现出中等的抗结核活性,分别具有36、30、15和20的抑制百分比。
