  摘要：

  在这项工作中，我们描述了2-亚苄基苯并呋喃-3-酮（aurones）的设计，合成和SAR研究，该化合物是CK2的新型强效抑制剂。已经合成了一系列的金酮。这些化合物在结构上与合成的黄酮有关，并显示出对CK2的纳摩尔活性。生化测试表明，有20种新合成的化合物抑制CK2，IC 50值在纳摩尔范围内。进行了进一步的基于属性的金质优化，产生了一系列亲脂效率增强的CK2抑制剂。最有效的化合物12m（BFO13）的CLipE = 4.94（CLogP = 3.5; IC 50  = 3.6 nM）与最知名的CK2抑制剂相当。

  A lighter future: Aurones have been identified as inhibitors of melanin biosynthesis. In this study, 24 aurones were evaluated on mushroom and bacterial tyrosinases (TyM and TyB). The compounds behaved as inhibitors, substrates, or activators of both enzymes. Our results highlight similarities and differences in behavior between TyM and TyB with the same set of molecules.

  We have identified naturally occurring 2-benzylidenebenzofuran-3-ones (aurones) as new templates for non-nucleoside hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp) inhibitors. The aurone target site, identified by site-directed mutagenesis, is located in thumb pocket I of HCV RdRp. The RdRp inhibitory activity of 42 aurones was rationally explored in an enzyme assay. Molecular docking studies were used to determine how aurones bind to HCV RdRp and to predict their range of inhibitory activity. Seven aurone derivatives were found to have potent inhibitory effects on HCV RdRp, with IC(50) below 5 mu M and excellent selectivity index (inhibition activity versus cellular cytotoxicity). The most active aurone analogue was (Z)-2-((1-butyl-1H-indo1-3-yl)methylene)-4,6-dihydroxybenzofuran-3(2H)-one (compound 51), with an IC(50) of 2.2 mu M. Their potent RdRp inhibitory activity and their low toxicity make these molecules attractive candidates as direct-acting anti-HCV agents.
• Functionalized aurones as inducers of NAD(P)H:quinone oxidoreductase 1 that activate AhR/XRE and Nrf2/ARE signaling pathways: Synthesis, evaluation and SAR

  The chemopreventive potential of functionalized aurones and related compounds as inducers of NAD(P) H:quinone oxidoreductase 1 (NQO1, EC 1.6.99.2) are described. Several 4,6-dimethoxy and 5-hydroxyaurones induced NQO1 activity of Hepa1c1c7 cells by 2-fold at submicromolar concentrations, making these the most potent inducers to be identified from this class. Mechanistically, induction of NQO1 was mediated by the activation of AhR/XRE and Nrf2/ARE pathways, indicating that aurones may be mixed activators of NQO1 induction or agents capable of exploiting the proposed cross-talk between the AhR and Nrf2 gene batteries. QSAR analysis by partial least squares projection to latent structures (PLS) identified size parameters, in particular those associated with non-polar surface areas, as an important determinant of induction activity. These were largely determined by the substitution on rings A and B. A stereoelectronic role for the exocyclic double bond as reflected in the E-LUMO term was also identified. The electrophilicity of the double bond or its effect on the conformation of the target compound are possible key features for induction activity. (c) 2010 Elsevier Masson SAS. All rights reserved.
• Synthesis of aurones and their inhibitory effects on nitric oxide and PGE2 productions in LPS-induced RAW 264.7 cells

  Sulfuretin is one of major constituents of Rhus verniciflua that exerts anti-inflammatory activities. Some of aurones were synthesized as sulfuretin derivatives and evaluated for their abilities to inhibit NO and PGE(2) production in LPS-induced RAW 264.7 cells in order to reveal the relationship. Of the aurones synthesized in the present study, 2h and 2i, which possess C-6 hydroxyl group in A-ring and methoxy substituents in B-ring, more potently inhibited NO and PGE(2) production and were less cytotoxic than sulfuretin.
