  Synthesis and antioxygenic activities of seabuckthorn flavone-3-ols and analogs

  摘要：

  A practical synthesis of polyhydroxy- and regiospecifically methylated flavone-3-ols which are components of commercial 'seabuckthorn flavone' has been achieved by modified Algar-Flynn-Oyamada method. Antioxidant activities of seabuckthorn extracts, isolated products and a number of flavone-3-ols have been determined. Structure-activity relationships have been discussed. Amongst the compounds tested, gallic acid, which is also present in seabuckthorn, was found to be the most effective antioxidant and radioprotectant. (C) 2011 Elsevier Ltd. All rights reserved.

  二氢黄酮醇衍生物作为抗炎剂的合成，生物学评估和分子对接

  摘要：

  通过经典的阿尔加-弗林-奥马达（AFO）反应从查耳酮合成了一系列二氢黄酮醇衍生物（4a - 4l），并在光谱分析的基础上进行了表征。评估了所有合成的化合物对脂多糖（LPS）刺激的RAW 264.7细胞系中促炎性诱导的TNF-α，IL-1beta和IL-6的抑制活性，并显示了多种功效。此外，通过使用两个经典模型选择化合物4d和4k来检查其体内抗炎活性。此处化合物4k与阿司匹林和美洛昔康这两个参考文献相比，在小鼠耳部肿胀模型中显示出最大的抗炎活性，抑制率为32.98％，在大鼠爪水肿模型中，间隔2小时的抑制作用为40.06％。在较低剂量下观察到类似的效果。此外，将化合物4k与环氧合酶-2对接以验证获得的药理数据，并为观察到的抗炎活性提供可理解的证据。

  To explore the structure-activity relationships on the inhibitory activity of flavanonols against nitric oxide (NO) production in inflammatory cells, we synthesized 19 flavanonols which shared a common 3,5,7-trihydroxychroman scaffold. A range of substitutions was included in the B ring in order to investigate the structure-activity relationship. We also succeeded in isolating stereoisomers from 16 of the flavanonols using chiral column chromatography. The inhibitory effects of these compounds on NO production were examined in RAW 264.7 cells (a murine macrophage-like cell line), which were activated by lipopolysaccharide (LPS). We only observed inhibitory activity against NO production in (2R,3R) stereoisomers, while the inhibitory activities of (2S,3S) stereoisomers were significantly weaker. We also evaluated the free radical scavenging potential of the flavanonols using 1,1-diphenyl-2-picrylhydrazyl (DPPH). Each stereoisomer indicated the equivalent DPPH scavenging potential as expected. The radical scavenging activity was not correlated with the inhibitory activity against NO. The inhibition of NO production by flavanonols is stereospecific and cannot simply be explained by their radical scavenging activity. We propose the possible existence of a 'target' molecule for flavanonols which is involved in the production and/or regulation of NO in RAW 264.7 cells. (C) 2015 Elsevier Ltd. All rights reserved.
