The biological properties of ailanthoidol, a neolignan from Zanthoxylum ailanthoides or Salvia miltiorrhiza Bunge, which is used in Chinese traditional herbal medicine, have not been evaluated. Here, we report that ailanthoidol inhibits inflammatory reactions in macrophages and protects mice from endotoxin shock. Our in vitro experiments showed that ailanthoidol suppressed the generation of nitric oxide (NO) and prostaglandin E 2 , as well as the expression of inducible NO synthase (iNOS) and cyclooxygenase (COX)‐2 induced by lipopolysaccharide (LPS) in RAW264.7 cells. Similarly, ailanthoidol inhibited the production of inflammatory cytokines induced by LPS in RAW264.7 cells, including interleukin (IL)‐1β and IL‐6. In an animal model, ailanthoidol protected BALB/c mice from LPS‐induced endotoxin shock, possibly through inhibition of the production of inflammatory cytokines and NO. Collectively, ailanthoidol inhibited the production of inflammatory mediators and may be a potential target for treatment of various inflammatory diseases. J. Cell.
