Abstract

Syringin (1), a natural bioactive 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 against NO production in the LPS-stimulated RAW264.7 cells. Among them, compounds 1-5, 7, and 9 exhibited different levels of anti-inflammatory activity.
