  针对Nrf2 /淀粉样蛋白-贝塔联络在阿尔茨海默氏病中的应用：一种合理的方法

  摘要：

  淀粉样蛋白是阿尔茨海默氏病（AD）的突出特征。然而，最近有人质疑淀粉样蛋白-β肽（Aβ）与疾病的发作和进展之间的线性联系。在这种情况下，Aβ和Nrf2途径之间的关键伙伴关系正变得至关重要，这为解密以Aβ为中心的疾病网络提供了前景。在这里，我们报告了一类新的抗聚集剂，它们经过合理设计，可以同时激活基于转录的抗氧化剂反应，其铅1在初步研究中显示出有趣的特性。根据Aβ识别的要求，我们确定了邻苯二酚衍生物12。在SH-SY5Y神经母细胞瘤细胞中，有12种结合了显着的自由基清除剂特性与通过转录反应的亲电激活来触发Nrf2途径和诱导Nrf2依赖性防御基因NQO1的能力。此外，与原型1相比，12阻止了细胞毒性稳定的寡聚中间体的形成，其效果明显更好，并且毒性更低。更重要的是，由于利用了不同的化学特征来调节Nrf2和Aβ活性，因此可以独立调节这两个途径。这些发现表明化合物12及其衍生物是研究Nrf2 /Aβ

  Onychomycosis is a common nail infection mainly caused by species belonging to the F. oxysporum, F. solani, and F. fujikuroi species complexes. The aim of this study was to evaluate the in vitro susceptibility of six representative strains of clinically relevant Fusarium spp. toward a set of natural-occurring hydroxycinnamic acids and their derivatives with the purpose to develop naturally occurring products in order to cope with emerging resistance phenomena. By introducing a prenylated chain at one of the hydroxy groups of trans-cinnamic acids 1–3, ten prenylated derivatives (coded 4–13) were preliminarily investigated in solid Fusarium minimal medium (FMM). Minimal inhibitory concentration (MIC) and lethal dose 50 (LD50) values were then determined in liquid FMM for the most active selected antifungal p-coumaric acid 3,3′-dimethyl allyl ester 13, in comparison with the conventional fungicides terbinafine (TRB) and amphotericin B (AmB), through the quantification of the fungal growth. Significant growth inhibition was observed for prenylated derivatives 4–13, evidencing ester 13 as the most active. This compound presented MIC and LD50 values (62–250 µM and 7.8–125 µM, respectively) comparable to those determined for TRB and AmB in the majority of the tested pathogenic strains. The position and size of the prenylated chain and the presence of a free phenol OH group appear crucial for the antifungal activity. This work represents the first report on the activity of prenylated cinnamic esters and ethers against clinical Fusarium spp. and opens new avenues in the development of alternative antifungal compounds based on a drug repositioning strategy.

  Onychomycosis是一种常见的指甲感染，主要由属于F. oxysporum、F. solani和F. fujikuroi物种复合体的物种引起。本研究旨在评估临床相关的六株代表性Fusarium spp.菌株对一组天然存在的羟基肉桂酸及其衍生物的体外敏感性，以开发天然产物，以应对新兴的耐药现象。通过在对固体Fusarium最小培养基（FMM）中引入一种烯丙基链到反式肉桂酸1-3的羟基中的十种烯丙基衍生物（编码为4-13），对其进行了初步研究。然后，在液体FMM中确定了对最活性的选定抗真菌p-香豆酸3,3'-二甲基烯丙酯13的最小抑制浓度（MIC）和半数致死量50（LD50）值，与常规杀菌剂特比萘啶（TRB）和两性霉素B（AmB）进行比较，通过对真菌生长的定量化。对于烯丙基衍生物4-13观察到显著的生长抑制，表明酯13是最活性的。该化合物的MIC和LD50值（分别为62-250 µM和7.8-125 µM）与大多数测试的致病菌株中确定的TRB和AmB的值相当。烯丙基链的位置和大小以及自由酚羟基的存在似乎对抗真菌活性至关重要。这项工作是关于烯丙基肉桂酸酯和醚对临床Fusarium spp.的活性的首次报告，并为基于药物再定位策略开发替代抗真菌化合物开辟了新途径。

  lipid mediators implicated in numerous inflammatory disorders. Caffeic acid phenethyl ester (CAPE) possesses potent anti-LTs activity through the inhibition of 5-lipoxygenase (5-LO), the key enzyme in the biosynthesis of LTs. In this study, we describe the design and synthesis of CAPE analogs as radical scavengers and 5-LO inhibitors. Caffeic esters bearing propargyl and allyl linkers between the caffeoyl

  白三烯（LTs）是一类脂质介体，与多种炎症性疾病有关。咖啡酸苯乙酯（CAPE）通过抑制5-脂氧合酶（5-LO）（LTs生物合成中的关键酶）而具有强大的抗LTs活性。在这项研究中，我们描述了作为自由基清除剂和5-LO抑制剂的CAPE类似物的设计和合成。通过Sonogashira和Heck交叉偶联反应合成了在咖啡酰基和芳基部分之间分别带有炔丙基和烯丙基连接基的咖啡酸酯（分别为4a-i和5a-i），以研究柔韧性和芳基取代对5-LO抑制的影响。合成了咖啡酰醇和醚（6，7a-b）以及咖啡酰醛和酮（8a-e），以阐明酯键对抑制活性的重要性。所有测试的化合物均被证明是良好的自由基清除剂（IC50为10-30μM）。在HEK293细胞模型中初步筛选抗LTs活性后，在人多形核白细胞（PMNL）中确定了所选化合物的5-LO抑制潜能。在PMNL的浓度依赖性测定中，大多数被筛选的化合物的性能均优于CAPE 3，其

  Forty caffeate analogues were synthesized via a convenient method starting from vanillin with moderate to good yields. The testing of biological activity of these compounds against HIV-1 integrase indicates that four compounds: bornyl caffeate, bornyl 2-nitrocaffeate, 5-nitrocaffeic acid and 5-nitrocaffeic acid phenethyl ester (5-nitroCAPE) possess a good HIV integrase inhibitory activity, IC50 19.9, 26.8, 25.0 and 13.5 mu M, respectively. Twelve caffeate analogues were tested by MTT assay on growth of human hepatocellular carcinoma BEL-7404, human breast MCF-7 adenocarcinoma, human lung A549 adenocarcinoma and human gastric cancer BCG823 cell lines, respectively. And the best result is IC50 5.5 mu M for CAPE against BEL-7404. (C) 2008 Elsevier Ltd. All rights reserved.

  We developed two efficient protocols for the synthesis of feruloyl and caffeoyl derivatives from commercial vanillin and veratraldehyde. Pharmacological activities were assessed against a panel of human cancer cell lines in vitro. Most synthesized compounds demonstrated attractive cytotoxicity. Several new compounds demonstrated significant antiproliferative and cytotoxic activities against HeLa and Bewo tumor cell lines. In particular, 5-nitro caffeic adamantyl ester showed broad spectrum of tumor inhibition in 10 cell lines, and reduced tumor weight by 36.7% in vivo when administered at a dose of 40 mg kg(-1).
