  Synthesis, biological evaluation and molecular modeling of dihydro-pyrazolyl-thiazolinone derivatives as potential COX-2 inhibitors

  摘要：

  A series of dihydro-pyrazolyl-thiazolinone derivatives (5a-5t) have been synthesized and their biological activities were also evaluated as potential cyclooxygenase-2 (COX-2) inhibitors. Among these compounds, compound 2-(3-(3,4-dimethylphenyl)-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl)thiazol-4(5H)-one (5a) displayed the most potent COX-2 inhibitory activity with IC50 of 0.5 mu M, but weak to COX-1. Docking simulation was performed to position compound 5a into the COX-2 active site to determine the probable binding model. Based on the preliminary results, compound 5a with potent inhibitory activity and low toxicity would be a potential and selective anti-cyclooxygenase-2 agent. (C) 2012 Elsevier Ltd.

  Fatty acid biosynthesis is essential for bacterial survival. FabH, beta-ketoacyl-acyl carrier protein (ACP) synthase III, is a particularly attractive target, since it is central to the initiation of fatty acid biosynthesis and is highly conserved among Gram-positive and - \negative bacteria. Fifty-six 1-acetyl-3,5-diphenyl-4,5-dihydro-(1H)-pyrazole derivatives were synthesized and developed as potent inhibitors of FabH. This inhibitor class demonstrates strong antibacterial activity. Escherichia coli FabH inhibitory assay and docking simulation indicated that the compounds 1-(5-(4-fluorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl) ethanone (12) and 1-(5-(4-chlorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl) ethanone (13) were potent inhibitors of E. coli FabH.

  Fourty-two thiazolyl-pyrazoline derivatives were synthesized to screen for their EGFR kinase inhibitory activity. Compound 4-(4-chlorophenyl)-2-(3-(3,4-dimethylphenyl)-5-p-tolyl-4,5-dihydro-1H-pyrazol-1-yl) thiazole (11) displayed the most potent EGFR TK inhibitory activity with IC(50) of 0.06 mu M, which was comparable to the positive control. Molecular docking results indicated that compound 11 was nicely bound to the EGFR kinase. Compound 11 also showed significant antiproliferative activity against MCF-7 with IC(50) of 0.07 mu M, which would be a potential anticancer agent. (C) 2011 Elsevier Ltd. All rights reserved.

  Two series of pyrazole derivatives designing for potential EGFR kinase inhibitors have been discovered. Some of them exhibited significant EGFR inhibitory activity. Compound 3-(3,4-dimethylphenyl)-5-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (C5) displayed the most potent EGFR inhibitory activity with IC50 of 0.07 mu M, which was comparable to the positive control erlotinib. Docking simulation was performed to position compound C5 into the EGFR active site to determine the probable binding model. Antiproliferative assay results indicating that some of the pyrazole derivatives own high antiproliferative activity against MCF-7. Compound C5 showed significant antiproliferative activity against MCF-7 with IC50 of 0.08 mu M. Therefore, compound C5 with potent inhibitory activity in tumor growth inhibition would be a potential anticancer agent. (C) 2010 Elsevier Ltd. All rights reserved.
