  investigate naturally occurring aurones (Z-benzylidenebenzofuran-3(2H)-one) and analogues as human tyrosinase inhibitors. Several aurones bearing hydroxyl groups on A-ring and different substituents on B-ring were synthesized and evaluated as inhibitors of human melanocyte-tyrosinase by an assay which measures tyrosinase-catalyzed l-Dopa oxidation. We found that unsubstituted aurones were weak inhibitors; however

  酪氨酸酶是铜依赖性酶，其将1-酪氨酸转化为多巴醌，并参与不同的生物学过程，例如黑色素生成和皮肤色素沉着。这项研究的目的是研究天然存在的金黄色素（Z-亚苄基苯并呋喃-3（2H）-one）和类似物作为人类酪氨酸酶抑制剂。合成了几种在A环上带有羟基且在B环上具有不同取代基的金酮，并通过测定酪氨酸酶催化的I-多巴氧化的方法评价了其作为人黑素细胞酪氨酸酶的抑制剂。我们发现未取代的金酮是弱抑制剂。然而，优选在4，6和4′位置具有两个或三个羟基的衍生物能够诱导显着的酪氨酸酶抑制作用。发现最有效的金黄色素是天然存在的4,6,4' -三羟基金酮在0.1 mM的浓度下可诱导75％的抑制作用，并且与曲酸（迄今为止已知的最佳酪氨酸酶抑制剂之一）相比非常有效（后者在该浓度下是完全无活性的）。如体内研究显示的那样，活性金氧烷没有毒性作用。

  the basic C6–C3–C6 skeleton is arranged as (Z)-2-benzylidenebenzofuran-3(2H)-one. These compounds are structural isomers of flavones and flavonols, natural products reported as potent inhibitors of SARS-CoV-2 replication. Herein, we report the design, synthesis, and anti-SARS-CoV-2 activity of a series of 25 aurones bearing different oxygenated groups (OH, OCH3, OCH2OCH3, OCH2O, OCF2H, and OCH2C6H4R)

• Functionalized aurones as inducers of NAD(P)H:quinone oxidoreductase 1 that activate AhR/XRE and Nrf2/ARE signaling pathways: Synthesis, evaluation and SAR
  作者：Chong-Yew Lee、Eng-Hui Chew、Mei-Lin Go

  日期：2010.7

  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.
