cytokines is considered to be a promising method for the treatment of inflammatory diseases. Herein, the total synthesis of a dibenzylbutane lignan, 9′--di-()-feruloyl--5,5′-dimethoxysecoisolariciresinol (LCA), was completed. A series of LCA derivatives were designed and synthesized, and their anti-inflammatory activities were evaluated. Derivative significantly inhibited LPS-induced expression of NO and the
急性肺损伤(ALI)是一个严重的公共卫生问题,发病率和死亡率很高。然而,临床上可用的有效药物很少。抑制促炎细胞因子被认为是治疗炎症性疾病的有前途的方法。在此,完成了二苄基丁烷木脂素9'-二-()-阿魏酰--5,5'-二甲氧基开环异落叶松树脂醇(LCA)的全合成。设计并合成了一系列LCA衍生物,并评估了它们的抗炎活性。衍生物显着抑制 LPS 诱导的 RAW 264.7 细胞中 NO 和促炎细胞因子 TNF-α、IL-6 和 IL-1β 的表达,并抑制 NF-κB 通路的激活。化合物可减少 LPS 诱导的小鼠肺部炎症和 ALI。它对 LPS 诱导的小鼠 ALI 具有显着的保护作用,并显着降低血清和支气管肺泡灌洗液中促炎细胞因子的水平。肺组织的湿重与干重的比率通过化合物标准化,这与抑制中性粒细胞浸润和促炎细胞因子的产生一致。化合物降低了一些促炎细胞因子的 mRNA 表达,改善了组织病理学变化,并
