Synthesis and in vitro anti Mycobacterium tuberculosis activity of a series of phthalimide derivatives

Abstract New phthalimide derivatives were easily prepared through condensation of phthalic anhydride and selected amines with variable yields (70–90%). All compounds ( 3a – l ) were evaluated against Mycobacterium tuberculosis H 37 Rv using Alamar Blue susceptibility. The compounds 3c , 3i , and 3l have the minimum inhibitory concentrations (MICs) of 3.9, 7.8, and 5.0 μg/mL, respectively, and could be considered new lead compounds in the treatment of tuberculosis and multi-drug resistant tuberculosis.
