Synthesis of some novel 2-substituted-5-[isopropylthiazole] clubbed 1,2,4-triazole and 1,3,4-oxadiazoles as potential antimicrobial and antitubercular agents

In the present study a series of 2-substituted-5-[isopropylthiazole] clubbed 1,2,4-triazole and 1,3,4-oxadiazole derivatives have been synthesized and characterized by IR, 1H NMR, 13C NMR and mass spectral analysis. Synthesized compounds were evaluated for their preliminary cytotoxicity, antimicrobial and antitubercular activity against Mycobacterium tuberculosis H37Rv strain by broth dilution assay method.Antimycobacterial activity tested against M. tuberculosis indicated that compounds 4b and 6g exhibited twofold enhanced potency than parent compound 1 and the results indicate that some of them exhibited promising activities and they deserve more consideration as potential antitubercular agents.Compound 3c, 4b and 6c exhibited good or moderate antibacterial inhibition and compounds 3h and 7c showed excellent antifungal activity.
