    Synthesis and Anti-Neuroinflammatory Activity of 1,7-diphenyl-1,4-heptadien-3-ones in LPS-Stimulated BV2 Microglia Via Inhibiting NF-κB/MAPK Signaling Pathways
    摘要:
    一系列具有不同取代基(HO-,CH3O-,CH3-,Cl-)的1,7-二苯基-1,4-庚二烯-3-酮被合成并在LPS刺激的BV2小胶质细胞中评估其抗神经炎症作用。药理结果显示,带有甲氧基的目标化合物极大地抑制了LPS诱导的NO释放,并且活性化合物CU-19和CU-21降低了LPS刺激的BV2细胞中NO,TNF-α,IL-6和PGE-2的水平,下调了COX-2和iNOS的表达。机制研究表明,CU-19和CU-21抑制了NF-κB的核转运和MAPKs(ERK,JNK和p38)的磷酸化。大鼠的初步药代动力学研究表明,与姜黄素的药代动力学性质相比,CU-19和CU-21的药代动力学性质显著改善。

    摘要:
    The biocatalytic reduction of aryl gamma,delta-unsaturated-beta-ketoesters was evaluated utilizing 24 different commercially available ketoreductases. In all cases, both (R) and (S)-enantiomers of gamma,delta-unsaturated beta-hydroxyesters were synthesized by one or more ketoreductases in excellent optical purity and yields. (C) 2013 Elsevier B.V.
