  2,3-Dideoxy hex-2-enopyranosid-4-uloses as promising new anti-tubercular agents: Design, synthesis, biological evaluation and SAR studies

  摘要：

  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 mu g/mL to 25 mu g/mL. A detailed SAR study on these hex-2-enopyranosid-4-uloses led to the identification of compound 5g (5007-724) which on the basis of low MIC (0.78 mu g/mL-M. tuberculosis H37Rv; 1.56 mu g/mL-MDR, SDR strains of M. tuberculosis; 0.78 mu g/mL-inhibition of intracellular replication of M. tuberculosis) and SI value of 13.5 has been identified as a promising lead molecule.

  A versatile new synthetic strategy utilizing MBH chemistry for the assembly of highly functionalized enantiopure sugar–pyrazole hybrid molecules with multiple sites for structural diversification and a non-flat skeleton as potential drug scaffolds is reported. Four representative hybrid molecules were screened for in vitro anti-cancer activity, wherein three of them were found to exhibit good anti-cancer activity.

  azide derivatives, transfer of chiral aryl/alkyl methanols from enulosides to pyridin-3-ones and pyridines, high yields, and short reaction times are key features of this method. The utility of the method has been further exemplified by demonstrating the usage of the 2-substituted 3-acetoxy-4-iodopyridine for the construction of biologically significant molecules like 2,7-disubstituted furo[2,3-c]pyridines
