Abstract/OtherAbstract:
Praeruptorin A (PA) is a pyranocoumarin compound isolated from the dried root of Peucedanum praeruptorum Dunn (Umbelliferae). However, the antiinflammatory effect of PA has not been reported. The present study investigated the antiinflammatory effect of PA in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells. PA significantly inhibited the LPS-induced production of nitric oxide (NO), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). The mRNA and protein expressions of inducible nitric oxide synthase (iNOS), IL-1β and TNF-α were also suppressed by this compound. Further study showed that PA decreased the cytoplasmic loss of inhibitor κB-α (IκB-α) protein and inhibited the translocation of NF-κB from cytoplasm to nucleus. Taken together, the results suggest that PA may exert antiinflammatory effects in vitro in LPS-stimulated RAW 264.7 macrophages through inhibition of NF-κB signal pathway activation.
