Description

一种白藜芦醇-苯酞杂合类化合物及其制备方法和用途
技术领域
本发明涉及一种白藜芦醇-苯酞杂合类化合物及其制备方法和用途,属于化学药品制备技术领域。
背景技术
天然产物白藜芦醇(Resveratrol)是一种具有二苯乙烯骨架的植物抗毒素,属于黄酮类的多酚化合物。1939年首次从毛叶藜芦的根部提取而获得,在自然界中广泛存在于葡萄、红酒、桑椹、花生等植物中,具有顺式和反式两种结构,在紫外照射下可以相互转化,自然界中主要以反式结构存在。白藜芦醇是一种天然的具有多酚结构的植物抗毒素,主要存在于葡萄的表皮种子、红酒、桑葚和花生等植物中。它具有广泛的药理作用,如抗癌症、抗氧化、抗菌抗炎、神经作用和对肝脏的保护作用等,但它存在选择性差、结构单一以及生物利用度低等缺点。
苯酞(PHthalide),中文名为邻羟甲基苯甲酸内酯,是一类含有异苯并呋喃酮骨架的杂环化合物,也系内酯类化合物,常用于药物和蒽醌类染料中间体的合成。现已发现的苯酞类化合物主要来自天然伞形科植物中,是当归、川芎等中药的有效成分,也存在于芹属、蛇床属等植物及真菌、细菌等微生物的代谢产物中。苯酞类化合物是指一类含有苯酞母核的化合物,其典型特征为苯环与γ-内酯环的双环融合结构。因为苯酞类化合物都具有典型的五元内酯环结构,所以其结构极不稳定,容易受到温度、光照等条件的影响而发生氧化、光热分解反应或结构转化等,这也是自然界中苯酞类化合物数量及结构繁多的重要因素。自然界中的苯酞类化合物结构主要以简单苯酞和二聚体苯酞呈现。国内外众多研究表明,苯酞类化合物具有抗肿瘤、抗炎、镇痛、抑菌、抗病毒、抗氧化、神经保护、改善心血管系统等多种生物活性。苯酞类化合物以其广泛的生理活性和结构可塑性强的独特优势逐渐成为药物化学领域研究的焦点。
近年来,合成苯并呋喃酮类化合物得到了深入研究并取得重要的进展。然而,现有的技术路线中需要使用昂贵的过渡金属催化剂、过量的氧化剂以及苛刻的反应条件等,这些缺陷限制了这些合成方法的实用性。本发明中,具有二苯乙烯结构的紫檀芪进行甲酰化和分子内氧化,在二苯乙烯分子骨架中引入五元内酯环结构,合成出了一系列新型白藜芦醇-苯酞杂合类化合物,在抗炎研究中发挥重要作用。

实施例15:白藜芦醇-苯酞杂合类衍生物(化合物D1-14)对促炎因子NO的抑制活性
我们利用Griess法测定LPS刺激RAW264.7细胞产生的NO含量,操作步骤如下:将在对数生长期的RAW264.7细胞接种到48孔板中,培养24h。将实验分为三组即空白组(不加LPS)、对照组(LPS刺激组)和不同浓度的化合物加药组,使其混合均匀,继续培养24h,之后弃去上清液,加入Griess reagent,室温放置半小时,后利用酶标仪测量各孔的吸光度值,计算待测样品对NO的抑制率。结果如图1所示。从图1中可以看出大部分化合物对促炎因子NO都具有抑制活性,其中化合物D2、D3、D6抑制活性较显著,特别是化合物D2对NO抑制活性最佳(IC50为0.76μM),有望成为有效的炎症抑制剂。
