Paeonol has been proved to have potential anti-inflammatory activity, but its clinical application is not extensive due to the poor anti-inflammatory activity (14.74% inhibitory activity at 20 μM). In order to discover novel lead compound with high anti-inflammatory activity, series of paeonol derivatives were designed and synthesized, their anti-inflammatory activities were screened in vitro and in vivo
丹皮酚已被证明具有潜在的抗炎活性,但由于其较差的抗炎活性(20μM时抑制活性为14.74%),其临床应用并不广泛。为了发现具有高抗炎活性的新型先导化合物,设计并合成了一系列丹皮酚衍生物,在体内外筛选了它们的抗炎活性。结构-活性关系(SARs)已被完全得出结论,最后(E)-N-(4-(2-乙酰基-5-甲氧基苯氧基)苯基)-3-(3,4,5-三甲氧基-苯氧基苯基)丙烯酰胺(化合物11a)被认为是最佳的低毒活性化合物,在20μM时对LP 26诱导的RAW 264.7巨噬细胞中一氧化氮(NO)的过度表达具有96.32%的抑制活性,IC50值为6.96μM。初步的机制研究表明,它可以抑制TLR4的表达,从而抑制NF-κB和MAPK通路。进一步的研究表明,化合物11a对佐剂诱导的大鼠关节炎模型具有明显的治疗作用。
