glucoside isolated from the root of Acanthopanax senticosus (Rupr. Maxim.) Harms, possesses significant anti-inflammatory activity. In this study, we have accomplished the total syntheses of syringin (1), along with its natural analogues 2–12, from a common starting material, syringaldehyde (13), in 4–8 steps with an overall yields of 11.8–61.3%. The anti-inflammatory activities of these compounds were determined
Syringin ( 1 ) 是一种从刺五加(Rupr. Maxim.) Harms的根中分离出来的天然生物活性糖苷,具有显着的抗炎活性。在这项研究中,我们已经完成了丁香苷 ( 1 ) 及其天然类似物2-12的全合成,从共同的起始材料丁香醛 ( 13 ) 开始,经过 4-8个步骤,总产率为 11.8-61.3% . 这些化合物的抗炎活性是根据 LPS 刺激的 RAW264.7 细胞中 NO 的产生来确定的。其中,化合物1 – 5、7和9表现出不同程度的抗炎活性。
