  Methods: In this study, the structural requirements for the inhibition of porcine pancreatic α- amylase by hydroxylated or methoxylated aurone derivatives were investigated by assessing their in vitro biological activities against porcine pancreatic α-amylase. Results: The structure-activity relationship of these inhibitors based on both in vitro and in silico findings showed that the hydrogen bonds

  背景：Aurones（Z）-2-亚苄基苯并呋喃-3-酮衍生物是黄酮的天然结构异构体，具有广阔的药理潜力。 方法：在这项研究中，通过评估其对猪胰腺α-淀粉酶的体外生物学活性，研究了羟基化或甲氧基化金酮衍生物抑制猪胰腺α-淀粉酶的结构要求。 结果：基于体外和计算机模拟的结果，这些抑制剂的构效关系表明，（Z）-亚苄基苯并呋喃-3-酮衍生物的A或B环的OH基团的氢键与该化合物的催化残基结合位点对其抑制活性至关重要。 结论：似乎金黄色素中的OH基团抑制α-淀粉酶的方式类似于黄酮和黄酮醇中的OH基团。
• 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.

  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.
