  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.

• Exploring the Promiscuous Enzymatic Activation of Unnatural Polyketide Extender Units in Vitro and in Vivo for Monensin Biosynthesis
  作者：Marius Grote、Frank Schulz

  DOI：10.1002/cbic.201800734

  日期：2019.5.2

  The incorporation of new-to-nature extender units into polyketide synthesis is an important source for diversity yet is restricted by limited availability of suitably activated building blocks in vivo. We here describe a straightforward workflow for the biogenic activation of commercially available new-to-nature extender units. Firstly, the substrate scope of a highly flexible malonyl co-enzyme A synthetase

  在聚酮化合物合成中引入新的自然扩展剂是多样性的重要来源，但由于体内适当活化的构建基团的有限可用性而受到限制。我们在这里描述了用于商业上可利用的新的自然扩展剂单元的生物激活的简单工作流程。首先，表征了来自肉桂链霉菌的高柔性丙二酸辅酶A合成酶的底物范围。该结果与体内实验相匹配，在体内实验中，所述扩展剂单元被莫能菌素生物合成途径的聚酮化合物合酶和辅助酶所接受。通过利用酰基转移酶的固有底物混杂和下游酶功能，实验产生了一系列可预测的莫能菌素衍生物。

  amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation
