    Abstract:
    A series of novel 1H-pyrrolo[2,3-d]pyrimidine-1,2,3-triazole derivatives have been synthesized in good to excellent yields. Through the copper-catalyzed azide-alkyne cycloaddition via reaction of 7-(prop-2-ynyl)-7H-pyrrolo[2,3-d]pyrimidine and aryl, heteroaryl and alkyl azides in the presence of CuSO4·5H2O and sodium ascorbate. These compounds were evaluated for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain. Most of these pyrrolopyrimidine-triazole hybrids exhibited good anti tubercular activity. The antimycobacterial assay results showed that the minimum inhibitory concentration of compounds 4q and 4r were 0.78 µg/mL. The molecular docking results also had shown highest Moldock score for same compounds. These novel compounds exhibited good inhibition activities and further structure-activity studies of the derivatives had shown promising features to use in antitubercular therapy.
