  作为有效胰腺脂肪酶抑制剂的烷氧基黄酮的设计、合成、生物学评价和分子对接

  摘要：

  橙酮是黄酮类化合物的一个小亚类。与查尔酮、黄酮和异黄酮等其他亚类不同，橙酮作为胰腺脂肪酶抑制剂尚未得到广泛研究。在这项工作中，我们研究了合成Aurone衍生物的胰腺脂肪酶抑制效力。设计并合成了属于四个系列（4,6-二羟基黄酮、6-羟基黄酮、4,6-二烷氧基黄酮和6-烷氧基黄酮）的36个化合物。通过分光光度法测定其体外抑制活性，并与槲皮素和奥利司他进行比较。具有长链（6-10 个碳）烷氧基取代基的烷氧基橙酮衍生物显示出更大的效力。其中，相对于槲皮素（IC50为86.98±3.859μM）和奥利司他（IC50为0.0334±0.0015μM），4,6-二烷氧基橙酮8表现出最高的抗胰腺脂肪酶活性（IC50为1.945±0.520μM）。荧光猝灭测量证实了烷氧基黄酮衍生物对胰腺脂肪酶的亲和力。动力学研究表明，8 通过竞争机制抑制脂肪酶（Ki 为 1.288 ± 0.282 µM）。分子对接结果阐明了

  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.

• 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.
• 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.

• Discovery and structure-activity relationship studies of 2-benzylidene-2,3-dihydro-1H-inden-1-one and benzofuran-3(2H)-one derivatives as a novel class of potential therapeutics for inflammatory bowel disease

  To develop effective therapeutics for inflammatory bowel disease (IBD), 2-benzylidene-2,3-dihydro-1-Hinden-1-one and benzofuran-3(2H)-one derivatives, were designed and synthesized and their structure activity relationships (SAR) were investigated. Compounds 7, 25, 26, 32, 39, 41, 52, 54, and 55 showed potent inhibitory effect (>70%) on the TNF-alpha-induced adhesion of monocytes to colon epithelial cells, which is one of the hallmark events leading to IBD. Such inhibitory activity of the compounds correlated with their suppressive activities against the TNF-alpha-induced production of ROS; ICAM-1 and MCP-1 expression, critical molecules involved in monocyte-epithelial adhesion; and NF-kappa B transcriptional activity. In addition, compounds 41 and 55 significantly suppressed the lipopolysaccharide (LPS)-induced expression of the TNF-alpha gene, with compound 55 showing better efficacy. This inhibition of TNF-alpha expression by compounds 41 and 55 corresponded to their additional inhibitory activity against AP-1 transcriptional activity, which is another transcription factor required for high level TNF-alpha expression. The strong inhibitory activity of compound 55 against an in vivo colitis model was confirmed by its dose dependent inhibitory activity in a rat model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis, demonstrating compound 55 as a new potential candidate for the development of therapeutics against IBD.

• Studies in Cell Suspension Cultures of Cassia didymobotrya. Part VI. The Biotransformation of Chalcones to Aurones and Auronols

  Cell-free extracts derived from tissue cultures of Cassia didymobotrya, which previously had been reported to convert 4-hydroxychalcones to flavones and biflavanones, catalyze the biotransformation of 2-hydroxychalcones to aurones and auronols. The aurone was shown to be the direct precursor of auronol.
