Original articleSynthesis and biological screening of 2′-aryl/benzyl-2-aryl-4-methyl-4′,5-bithiazolyls as possible anti-tubercular and antimicrobial agents

Add time:09/08/2019    Source:sciencedirect.com

A series of 2′-aryl/benzyl-2-aryl-4-methyl-4′,5-bithiazolyl derivatives, 25–64 were synthesized and evaluated for inhibitory activity against Mycobacterium smegmatis MC2 155 strain and antimicrobial activities against four pathogenic bacteria Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Proteus vulgaris. Among them, compounds 40, 49, 50, and 54 exhibited moderate to good inhibition on the growth of the bacteria Mycobacterium smegmatis at the concentration of 30 μM. Compounds 26, 40, 44, 54 and 56 exhibited moderate to good antibacterial activity. Compound 5-(2′-(4-fluorobenzyl)thiazol-4′-yl)-2-(4-fluorophenyl)-4-methyl-thiazole (54) exhibited both antitubercular as well as antimicrobial activity against all tested strains.
