A series of novel dibenzofuran tethered thiazolyl-1,2,3-triazolyl acetamides, designed by assembling antitubercular pharmacophoric fragments, dibenzofuran, 2-aminothiazole and substituted triazoles in one molecular architecture, were evaluated against Mycobacterium tuberculosis. The new analogues 6a-p accomplished in four step synthetic sequence utilizing click chemistry in the penultimate step, was fully characterized by their NMR and mass spectral data. Among the compounds 6a-p screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv, three compounds 6j (MIC: 1.56 mu g/mL); 6a and 6p (MIC: 3.13 mu g/mL) was found to be most active and exhibited lower cytotoxicity. Among these three, 6j could be a candidate to consider as a drug like hit analogue for further development. (C) 2016 Elsevier Ltd. All rights reserved.
