  Selection, synthesis, and anti-inflammatory evaluation of the arylidene malonate derivatives as TLR4 signaling inhibitors

  摘要：

  Inhibition of TLR4 signaling is an important therapeutic strategy for intervention in the etiology of several pro-inflammatory diseases. There has been intensive research in recent years aiming to explore this strategy, and identify small molecule inhibitors of the TLR4 pathway. However, the recent failure of a number of advanced drug candidates targeting TLR4 signaling (e.g., TAK242 and Eritoran) prompted us to continue the search for novel chemical scaffolds to inhibit this critical inflammatory response pathway. Here we report the identification of a group of new TLR4 signaling inhibitors through a cell-based screening. A series of arylidene malonate analogs were synthesized and assayed in murine macrophages for their inhibitory activity against LPS-induced nitric oxide (NO) production. The lead compound 1 (NCI126224) was found to suppress LPS-induced production of nuclear factor-kappaB (NF-kappa B), tumor necrosis factor (TNF-alpha), interleukin-1 beta (IL-1 beta), and nitric oxide (NO) in the nanomolar-low micromolar range. Taken together, this study demonstrates that 1 is a promising potential therapeutic candidate for various inflammatory diseases. (C) 2012 Elsevier Ltd. All rights reserved.
