Design, synthesis and characterization of novel 2-(2,4-disubstituted-thiazole-5-yl)-3-aryl-3H-quinazoline-4-one derivatives as inhibitors of NF-κB and AP-1 mediated transcription activation and as potential anti-inflammatory agents
摘要:
A series of 2-(2,4-disubstituted-thiazole-5-yl)-3-aryl-3H-quinazoline-4-one derivatives were designed and synthesized. Synthesized molecules were further evaluated for their inhibitory activity towards transcription factors NF-kappa B and AP-1 mediated transcriptional activation in a cell line based in vitro as well as for their anti-inflammatory activity in in vivo model of acute inflammation. This series provides us with selective and dual inhibitors of NF-kappa B and AP-1 mediated transcriptional activation which also exhibit significant efficacy in in vivo model of inflammation. Two of the compounds 9m and 9o turned out to be the most promising dual inhibitors of NF-kappa B and AP-1 mediated transcriptional activation with an IC50 of 3.3 mu M for both. 9n (IC50 = 5.5 mu M) and 9p (IC50 = 5.5 mu M) emerged as selective inhibitors of NF-kappa B mediated transcriptional activation and 9c (IC50 = 5.5 mu M) and 9d (IC50 = 5.5 mu M) were found to be more selective inhibitor of AP-1 mediated transcriptional activity. Though the relationship between the activities shown by these compounds in in vivo and in vitro model is still to be established, these results suggest the suitability of the designed molecular framework as a potential anti-inflammatory molecular framework which also exhibits the inhibitory activity towards NF-kappa B and AP-1 mediated transcriptional activation. This will be worth studying further to explore its complete potential particularly in chronic inflammatory conditions. The structure activity relationship (SAR) of this series has been discussed herein. (C) 2008 Elsevier Masson SAS. All rights reserved.
