The alarming resurgence of tuberculosis (TB) underlines the urgent need for development of new and potent anti-TB drugs. Towards this goal we herein report the design and synthesis of 2,3-dideoxy hex-2-enopyranosid-4-uloses as promising new anti-tubercular agents. These easily accessible, small molecules were found to exhibit in vitro activity against Mycobacterium tuberculosis H37Rv in a MIC range of 0.78 μg/mL to 25 μg/mL. A detailed SAR study on these hex-2-enopyranosid-4-uloses led to the identification of compound 5g (S007-724) which on the basis of low MIC (0.78 μg/mL-M. tuberculosis H37Rv; 1.56 μg/mL-MDR, SDR strains of M. tuberculosis; 0.78 μg/mL-inhibition of intracellular replication of M. tuberculosis) and SI value of 13.5 has been identified as a promising lead molecule.
