  Synthesis and Sar Study of Diarylpentanoid Analogues as New Anti-Inflammatory Agents

  摘要：

  合成了97系列二苯基戊烷类化合物，并通过使用γ干扰素（IFN-γ）/脂多糖（LPS）刺激的RAW264.7巨噬细胞进行NO抑制试验评估其抗炎活性。12个化合物（9, 25, 28, 43, 63, 64, 81, 83, 84, 86, 88和97）与姜黄素（14.7 ± 0.2 µM）相比显示出更大或相似的NO抑制活性，特别是化合物88和97，它们表现出最显著的NO抑制活性，IC50值分别为4.9 ± 0.3 µM和9.6 ± 0.5 µM。结构-活性关系（SAR）研究表明，两个芳香环上羟基的存在对这些分子的生物活性至关重要。除了多酚类衍生物外，A环上低电子密度和B环上高电子密度对提高NO抑制作用很重要。同时，药效团映射表明，B环上间位和对位上的羟基取代可能是高活性二苯基戊烷类化合物的标记。

  A one-pot synthesis of novel benzopyran-4-ones is described. In a tandem reaction, organobase-catalysed Michael addition of (RCOCH2COR2)-C-1 on chromone-3-carboxylic acid led to decarboxylation and pyran-4-one ring opening of the latter. This was followed by chromone- and/or chromanone ring closure of the resulting Michael adducts when R-1 is an ortho-hydroxyaryl group. Antioxidant testing of 14 derivatives

  application of Triton-B adsorbed on flyash (a waste material of thermal plants ) has been reported for the variety of base catalysed reactions such as synthesis of cinnamic acids by Deobner reaction, synthesis of 1-(2-hydroxyphenyl)-5-phenylpent-4-ene-1, 3-diones by Baker- Venkataraman reaction and synthesis of 3-carboxycoumarins by knoevenagel reaction. This material also acts as a support for the reaction

  Xanthones are a class of oxygen-containing heterocyclic compounds widely distributed in nature. The natural derivatives can present different substitutions in the xanthone core that include hydroxyl, methoxyl, prenyl and glycosyl groups. The inclusion of aryl groups has only been reported for a few synthetic derivatives, the 2,3-diaryl moiety being recently introduced by our group. Xanthones are endowed with a broad spectrum of biological activities, many of them related to their antioxidant ability, including the scavenging of reactive oxygen species (ROS) and reactive nitrogen species (RNS), as well as metal chelating effects. Considering the interesting and promising antioxidant activities present in compounds derived from the xanthone core, the main goal of this work was to evaluate the scavenging activity of the new 2,3-diarylxanthones for ROS, including superoxide radical (O-2(center dot-)), hydrogen peroxide (H2O2), singlet oxygen (O-1(2)), peroxyl radical (ROO center dot) and hypochlorous acid (HOCl), and RNS, including nitric oxide ((NO)-N-center dot) and peroxynitrite anion (ONOO center dot). The obtained results revealed that the tested 2,3-diarylxanthones are endowed with outstanding ROS and RNS scavenging properties, considering the nanomolar to micromolar range of the IC50 values found. The xanthones with two catechol rings were the most potent scavengers of all tested ROS and RNS. In conclusion, the new 2,3-diarylxanthones are promising molecules to be used for their potential antioxidant properties. (C) 2010 Elsevier Ltd. All rights reserved.

  Human noroviruses (NoV) are now recognized as the most frequent cause of outbreaks and sporadic cases of acute gastroenteritis. Despite the significant economic impact and considerable morbidity of norovirus disease, no drug or vaccine is currently available to treat or prevent this disease, therefore the discovery of anti-norovirus drugs is urgent.In the present work, a total of 12 structure related chromone and (E)-2-styrylchromones were evaluated for their potential anti-norovirus activity using the murine norovirus (MNV) as a surrogate model for human NoV.From the 12 compounds studied, six (E)-2-styrylchromones were found to have with interesting antinorovirus activity. The best compounds of the series were (E)-5-hydroxy-2-styrylchromone and (E)-4'-methoxy-2-styrylchromone with an IC50 approximate to 7 mu M. A first insight into the mechanism of action of these compounds was possible. An interesting relationship between the anti-norovirus activity and the chemical structure was observed. The present study points out that the (E)-2-styrylchromones skeleton is an important one which deserves to be developed and further explored as new antiviral drugs against NoV. (C) 2010 Elsevier Ltd.
