The aim of this work was to synthesize a series of compounds to study their antimycobacterial potential. Eight compounds were found to be most active with minimum inhibitory concentration of less than 6μM and were more active than Isoniazid (INH) against Mycobacterium tuberculosis H37Rν (MTB). Compounds with electron withdrawing group substituted on the aryl ring were showing better activity. Among the fifteen newly synthesized compounds, compound 6-methyl-4-(4-nitrophenyl)-2-oxo-N-(pyridin-2-yl)-1,2,3,4tetrahydropyrimidine-5- carboxamide (B) was found to be the most active agent against MTB and INH resistant Mycobacterium tuberculosis (INHR-MTB) with minimum inhibitory concentration of <0.35 μM.
