  Discovery of a benzenesulfonamide-based dual inhibitor of microsomal prostaglandin E2 synthase-1 and 5-lipoxygenase that favorably modulates lipid mediator biosynthesis in inflammation

  摘要：

  Leukotrienes (LTs) and prostaglandin (PG)E-2, produced by 5-lipoxygenase (5-LO) and microsomal prostaglandin E-2 synthase-1 (mPGES-1), respectively, are key players in inflammation, and pharmacological suppression of these lipid mediators (LM) represents a strategy to intervene with inflammatory disorders. Previous studies revealed that the benzenesulfonamide scaffold displays efficient 5-LO-inhibitory properties. Here, we structurally optimized benzenesulfonamides which led to an N-phenyl-benzenesulfonamide derivative (compound 47) with potent inhibitory activities (IC50 = 2.3 and 0.4 mu M for isolated 5-LO and 5-LO in intact cells, respectively). Compound 47 prevented the interaction of 5-LO with its activating protein (FLAP) at the nuclear envelope in transfected HEK293 cells as shown by in situ proximity ligation assay. Comprehensive assessment of the LM profile produced by human macrophages revealed the ability of 47 to selectively down-regulate pro-inflammatory LMs (i.e. LTs and PGE(2)) in M1 but to enhance the formation of pro-resolving LMs (i.e. resolvins and maresins) in M2 macrophages. Moreover, 47 strongly inhibited LT formation and cell infiltration in two in vivo models of acute inflammation (i.e., peritonitis and air pouch sterile inflammation in mice). Together, 47 represents a novel LT biosynthesis inhibitor with an attractive pharmacological profile as anti-inflammatory drug that also promotes the biosynthesis of pro-resolving LM.

  The synthesis of two series of β-amino ketones containing a p-aminobenzoic acid moiety (TM-1 and TM-2) using a modified protocol of the Mannich reaction is reported. The molecular structures of a total of tweenty three new target compounds were characterized by 1H NMR, 13C NMR, ESI-MS and HR-MS. Subsequently, their antidiabetic activities were screened in vitro. The α-glucodase inhibition (α-GI) activity of compound 1e reached a remarkable level of 66.50%. The peroxisome proliferator-activated receptor (PPAR) relative activation activities of six compounds are above 80%, and in particular 2i displays an unprecedentedly high PPAR of 130.91%. The structure-activity relationships of the compounds were established. 2i is also subject to further in-depth investigation.

  Catalytic reduction reactions play a major role in modern chemistry and are often based on hydrogen gas as a reducing agent. However, the high reactivity of hydrogen is often accompanied by low selectivity on the simple catalysts. Herein, we showed that the usage of syngas as a reducing agent can be a more efficient and selective strategy. Based on control experiments, a plausible mechanism was proposed

  Current approaches to the reductive amination are often nonselective, require complicated catalysts, or are not atom-economical. The application of syngas as a mild and selective reducing agent to aminate carbonyl compounds unstable under hygrogenation conditions with functional groups, which furnished a broad substrate scope, is demonstrated herein.
