synthesized by condensation of 2-amino-5-aryl-5H-thiazolo[4,3-b]-l,3,4-thiadiazole with various aryl aldehydes. The synthesized compounds were characterized by FTIR, 1H-NMR, 13C-NMR and mass spectra. The titled compounds 3a-l and 4a-l were evaluated for anti-tubercular activity at a concentration of 0.1-100 μg/mL by Microplate Blue Alamar Assay method. Azetedinones 4a-l showed very good inhibition against
在三乙胺存在下,通过氨基噻二唑的各种席夫碱与氯乙酰氯的环缩合反应,合成了一系列十二种新颖的氮杂环丁烷酮4a-1。通过2-氨基-5-芳基-5H-噻唑并[4,3-b] -1,3,4-噻二唑与各种芳基醛的缩合合成了各种新颖的席夫碱3a-1。通过FTIR,1 H-NMR,13 C-NMR和质谱对合成的化合物进行表征。通过Microplate Blue Alamar测定法,以0.1-100μg/ mL的浓度评价标题化合物3a-1和4a-1的抗结核活性。与化合物3a-1和标准链霉素和吡嗪酰胺相比,氮杂环丁烷酮4a-1对结核分枝杆菌的生长表现出非常好的抑制作用。
