  Anti-inflammatory Constituents of the Red Alga Gracilaria verrucosa and Their Synthetic Analogues

  摘要：

  A chemical study on the anti-inflammatory components of the red alga Gracilaria verrucosa led to the isolation of new 11 -deoxyprostaglandins (1-4), a ceramide (5), and a C-16 keto fatty acid (6), along with known oxygenated fatty acids (7-14). Their structures were elucidated on the basis of NMR and MS data. The absolute configurations of compounds 1-5 were determined by Mosher's method. The anti-inflammatory activity of the isolated compounds (1-14) was evaluated by determining their inhibitory effects on the production of pro-inflammatory mediators (NO, IL-6, and TNF-alpha) in lipopolysaccharide (LPS)-activated RAW 264.7 murine macrophage cells. Compounds 9 and 10 exhibited the most potent activity. In the evaluation of these two compounds and derivatized analogues (15-40), the anti-inflammatory activity was enhanced in some synthetic analogues. These enone fatty acids were investigated as potential anti-inflammatory leads for the first time.

  摘要：

  通过监测针对赤潮浮游植物沙门氏菌的拟南芥活性，生物测定指导的济州毛Tri甲醇提取物的分离导致分离出由四种异构体组成的活性部分。活性化合物鉴定为（E）-9-羟基十八碳烯-10 （1），（E）-10-羟基十八碳烯-8（2），（E）-11-羟基-12-12烯酸（3）和（E）-12-羟基十八烷基-10-烯酸（4NMR，IR和质谱数据）。结构通过与那些真实样品的NMR和MS数据的比较确认1 - 4由明确的合成而获得。合成的羟基酸1 - 4和相关化合物进行了评估针对杀藻活性C.蝇并且发现的所有1 - 4具有高的活性（> 80％的死亡率在第24小时）在20微克/ mL的浓度。使用11种相关化合物进行的结构-活性关系研究表明，羟基的存在对于活性很重要，双键可能被三键取代。

  A series of endogenous fatty acid amides and their analogues (1-78) were prepared, and their inhibitory effects on pro-inflammatory mediators (NO, IL-1 beta, IL-6, and TNF-alpha) in LPS-activated RAW264.7 cells were evaluated. Their inhibitory activity on the pro-inflammatory chemokine MDC in IFN-gamma-activated HaCaT cells was also examined. The results showed that the activity is strongly dependent on the nature of the fatty acid part of the molecules. As expected, the amides derived from enone fatty acids showed significant activity and were more active than those derived from other types of fatty acids. A variation of the amine headgroup also altered bioactivity profile remarkably, possibly by modulating cell permeability. Regarding the amine part of the molecules, N-acyl dopamines exhibited the most potent activity (IC50 similar to 2 mu M). This is the first report of the inhibitory activity of endogenous fatty acid amides and their analogues on the production of nitric oxide, cytokines (IL-1 beta, IL-6, and TNF-alpha) and the chemokine MDC. This study suggests that the enone fatty acid-derived amides (such as N-acyl ethanolamines and N-acyl amino acids) and N-acyl dopamines may be potential anti-inflammatory leads.
