Nortrachelogenin
is a pharmacologically active lignan found in knot extracts of
Pinus sylvestris
. In previous studies, some lignans have been shown to have anti-inflammatory properties, which made nortrachelogenin an interesting candidate for our study. In inflammation, bacterial products and cytokines induce the expression of inducible nitric oxide synthase, cyclooxygenase-2, and microsomal prostaglandin E synthase-1. These enzymes synthesize factors, which, together with proinflammatory cytokines, are important mediators and drug targets in inflammatory diseases.The effects of nortrachelogenin on the expression of inducible nitric oxide synthase, cyclooxygenase-2, and microsomal prostaglandin E synthase-1 as well as on the production of nitric oxide, prostaglandin E

and monocyte chemotactic protein-1 were investigated in the murine J774 macrophage cell line. In addition, we examined the effect of nortrachelogenin on carrageenan-induced paw inflammation in mice.Interestingly, nortrachelogenin reduced carrageenan-induced paw inflammation in mice and inhibited the production of inflammatory factors nitric oxide, prostaglandin E

Nortrachelogenin
inhibited microsomal prostaglandin E synthase-1 protein expression but had no effect on cyclooxygenase-2 protein levels.
Nortrachelogenin
also had a clear inhibitory effect on inducible nitric oxide synthase protein expression but none on its mRNA levels, and the proteasome inhibitor lactacystin reversed the effect of nortrachelogenin on inducible nitric oxide synthase expression, suggesting a post-transcriptional mechanism of action.The results revealed hitherto unknown anti-inflammatory properties of nortrachelogenin, which could be utilized in the development of anti-inflammatory treatments.
