Design, synthesis and biological evaluation of novel pyrazole-based compounds as potential chemotherapeutic agents.

Design and synthesis of pyrazole-based chemotherapeutic agents. A series of novel diphenyl pyrazole-chalcone derivatives were synthesized and assessed for their cytotoxic activities against 14 cancer cell lines and their antimicrobial activities against MRSA and along with their safety using HSF normal cell line. Majority of the compounds showed moderate-to-significant anticancer activity with selective high percentage inhibition (>80%) against HNO-97 while being nontoxic toward normal cells. Compounds and were the most potent congeners with IC of 10 and 10.56 μM respectively. The synthesized compounds exhibited moderate to potent antimicrobial activities. Interestingly, compound exhibited a minimum inhibitory concentration of 15.7 μg/ml against MRSA; and a minimum inhibitory concentration of 7.8 μg/ml versus .
