  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

• 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.

  isoflavones, aurones have not been extensively explored as pancreatic lipase inhibitors. In this work, we studied the pancreatic lipase inhibitory potency of synthetic aurone derivatives. Thirty-six compounds belonging to four series (4,6-dihydroxyaurone, 6-hydroxyaurone, 4,6-dialkoxyaurone, and 6-alkoxyaurone) were designed and synthesized. Their in vitro inhibitory activities were determined by spectrophotometric
