H37Rv (MTB) and multi-drug resistant M. tuberculosis (MDR-TB) using agar dilution method. Among the synthesized compounds, spiro[5.3′′]-5′′-nitrooxindole-spiro-[6.3′]-1′-methyl-5′-(2,4-di-chlorophenylmethylidene)tetrahydro-4′(1H)-pyridinone-7-(2,4-dichlorophenyl)tetra-hydro-1H-pyrrolo[1,2-c][1,3]thiazole (9k) was found to be the most active with a minimum inhibitory concentration (MIC) of 0.6 μM against
源自取代的靛红和1,3-噻唑烷-4-羧酸的偶氮甲亚胺的1,3-偶极环加成反应生成一系列1-甲基-3,5-双[(E)-芳基亚甲基]-四氢-4( 1 H)-吡啶酮以定量产率提供了化学,区域和立体选择性的新型螺-吡咯并噻唑。使用琼脂稀释法筛选这些化合物的抗结核分枝杆菌H37Rv(MTB)和耐多药结核分枝杆菌(MDR-TB)的体外活性。在合成的化合物中,螺[5.3''-5''-硝基氧吲哚-螺-[6.3']-1'-甲基-5'-(2,4-二氯苯基亚甲基)四氢-4'(1 H)吡啶酮-7-(2,4-二氯苯基)四氢-1 H-吡咯并[1,2-发现c ] [1,3]噻唑(9k)最具活性,对MTB和MDR-TB的最低抑菌浓度(MIC)为0.6μM。
