Design, synthesis and anti-inflammatory evaluation of novel 5-benzylidene-3,4-dihalo-furan-2-one derivatives
摘要:
Rosiglitazone has shown promising anti-inflammation effect. To develop preferable anti-inflammatory agents, twenty-two rosiglitazone analogs were synthesized and their anti-inflammatory activity was evaluated. Among these compounds, 6i and 6k displayed excellent inhibitory activities on the production of inflammatory mediators, including nitric oxide (NO), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Furthermore, 6i and 6k showed suppression effects on the nuclear factor-kappa B (NF-kappa B) and mitogen-activated protein kinase (MAPK) pathways, and this suppression effects could be partially reversed by GW9662, which is a peroxisome proliferator-activated receptor gamma (PPAR gamma) antagonist. Additionally, our docking results exhibited the well combination of 6i and 6k to PPAR gamma. So the anti-inflammation activity of 6i and 6k was due at least in part, to their interaction with PPAR gamma. (C) 2013 Elsevier Masson SAS. All rights reserved.
