An efficient and practical preparation of 2-arylbenzo[b]furan molecules including natural egonol, XH-14, ailanthoidol, and unnatural derivatives is demonstrated using Sonogashira coupling, iodine induced cyclization and Wittig reaction. Anti-inflammatory effects of the prepared benzo[b]furans were examined in lipopolysaccharide (LPS)-stimulated RAW 264-7 macrophages. The results showed that ailanthoidol, XH-14 and three other unnatural derivatives (9-10, 13) inhibited significantly the production of inflammatory mediator nitric oxide without showing cytotoxicity.
展示了一种高效且实用的合成2-芳基苯并[b]呋喃分子的制备方法,包括天然的艾戈诺尔、XH-14、白蜡醇和一些非天然衍生物,采用了Sonogashira偶联、碘诱导环化和Wittig反应。所制备的苯并[b]呋喃的抗炎作用在脂多糖(LPS)刺激的RAW 264-7巨噬细胞中进行了检测。结果显示,白蜡醇、XH-14和其他三种非天然衍生物(9-10,13)显著抑制了炎性介质一氧化氮的生成,并且未表现出细胞毒性。
