A series of twelve dispiropyrrolidines were synthesized using [3+2]-cycloaddition reactions. The synthesized compounds were screened for their antimycobacterial activity against M. tuberculosis H(37)Rv and INH resistant M. tuberculosis strains using agar dilution method, four of them showed good activity with MIC of less than 1 mu M. Compound 4'-[5-(4-fluorophenyl) pyridin-3-yl]-1'-methyldispiro[indan-2,2' pyrrolidine-3',2 ''-indan]-1,3,1 ''-trione (4b) was found to be the most active with MIC of 0.1215 and 5.121 mu M, respectively.
