  摘要：

  一系列的4-羟基-6-甲氧基黄烷酮和4,6-二甲氧基黄烷酮已经被合成并测试了其对P-糖蛋白核苷酸结合域的结合亲和力，P-糖蛋白是一种介导癌细胞耐药性对化疗的ABC（ATP结合盒）转运蛋白。这些化合物在黄烷酮B环上的取代基性质上有差异。结合亲和力似乎与取代基的性质以及4位上羟基的有无相关。活性最强的化合物是4′-溴-4-羟基-6-甲氧基黄烷酮和4-羟基-4′-碘-6-甲氧基黄烷酮。

  Natural and synthetic 2′-hydroxy-chalcones and aurones: Synthesis, characterization and evaluation of the antioxidant and soybean lipoxygenase inhibitory activity

  摘要：

  A series of 2'-hydroxy-chalcones and their oxidative cyclization products, aurones, have been synthesized and tested for their antioxidant and lipoxygenase inhibitory activity. The natural product aureusidin (31) was synthesized in high yield by a new approach. An extensive structure-relationship study was performed and revealed that several chalcones and aurones possess an appealing pharmacological profile combining high antioxidant and lipid peroxidation activity with potent soybean LOX inhibition.

  their ability to modulate ABCG2 (breast cancer resistance protein)-mediated multidrug resistance in vitro. Several members (0.5 microM) increased the accumulation of mitoxantrone (MX) in human breast cancer cells (MDA-MB-231) transfected with ABCG2 and re-sensitized these cells to the cytotoxic effects of MX. In the re-sensitization assay, aurones at 0.5 microM reduced the resistance of the transfected

• A One-Pot Synthesis of Aurones from Substituted Acetophenones and Benz­aldehydes: A Concise Synthesis of Aureusidin

  A one-pot synthesis of aurones from substituted acetophenone and benzaldehyde has been developed on the basis of an improved Algar-Flynn-Oyamada reaction. By using this method, several aurones were prepared in three steps from commercial starting materials. The usefulness of this one-pot strategy was confirmed by a synthesis of aureusidin, an inhibitor of iodothyronine deiodinase, in 41% overall yield. In comparison with a two-step synthesis of this product from the same substrates, the one-pot strategy was more effective, giving a higher yield and requiring fewer and simpler operations.
• 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.
