Flavonoids are polyphenols with broad known pharmacological properties. A series of 2,3-dihydroflavanone derivatives were thus synthesized and investigated for their anti-inflammatory activities. The target flavanones were prepared through cyclization of 2′-hydroxychalcone derivatives, the later obtained by Claisen–Schmidt condensation. Since nitric oxide (NO) represents an important inflammatory mediator
黄酮类化合物是具有广泛已知药理特性的多酚。因此合成了一系列 2,3-二氢黄烷酮衍生物并研究了它们的抗炎活性。目标黄烷酮通过 2'-羟基查耳酮衍生物的环化制备,后者通过 Claisen-Schmidt 缩合获得。由于一氧化氮 (NO) 是一种重要的炎症介质,因此使用 Griess 试验在体外评估了各种黄烷酮对 LPS 诱导的 RAW 264.7 巨噬细胞中 NO 产生的影响。最活跃的化合物是黄烷酮 (4G)、2'-羧基-5,7-二甲氧基黄烷酮 (4F)、4'-溴-5,7-二甲氧基黄烷酮 (4D) 和 2'-羧基黄烷酮 (4J) ,IC50 值分别为 0.603、0.906、1.030 和 1.830 µg/mL。相比之下,松松素的 IC50 值为 203.60 µg/mL。因此,在这项工作中合成的衍生物与松松素相比具有更高的 NO 抑制能力,证明了药物调节对提高天然分子的生物学潜力的重要性。SAR
