    Abstract:
    Various substituted 4,6-diarylpyrimidin-2-amine (4), 4,6-diaryl-2-(heteroaryl)pyrimidine (6) and 1-(3,5-diaryl-4,5-dihydro-1H-pyrazol-1-yl)ethanone (7) derivatives were synthesized in good yields using simple methodology. The synthesized compounds (4-7) were evaluated for their in vitro anti-tubercular activity against Mycobacterium tuberculosis H37Rv strain. Compounds 4a, 6b, 7b, and 7c exhibited significant anti-tubercular activity at MIC values 25, 25, 12.5 and 12.5 μM concentration. In vitro cytotoxicity data using non cancerous hepatic monocytes (THP-1) cells indicated that most active compounds 7b and 7c were safe as their MIC values were much lower than their cytotoxic values.
