evaluation of these compounds showed that selectivecancercell toxicity (in vitro using human lung and breast cancercell lines) might be due to the inhibition of antioxidant enzymes instigating elevated ROS levels which triggers intrinsic apoptotic pathways. These compounds were found nontoxic to the normal human primary cells. Compound 4a, was found to be competitive inhibitor of colchicine and in

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 mu M 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.
