  • Title: Chebulagic acid (CA) attenuates LPS-induced inflammation by suppressing NF-kappaB and MAPK activation in RAW 264.7 macrophages.
    Author: Reddy DB, Reddanna P.
    Journal: Biochem Biophys Res Commun; 2009 Mar 27; 381(1):112-7. PubMed ID: 19351605.
    Abstract:
    Chebulagic acid (CA), a natural anti-oxidant, showed potent anti-inflammatory effects in LPS-stimulated RAW 264.7, a mouse macrophage cell line. These effects were exerted via inhibition of NO and PGE2 production and down-regulation of iNOS, COX-2, 5-LOX, TNF-alpha and IL-6. CA inhibited NF-kappaB activation by LPS, and this was associated with the abrogation of IkappaB-alpha phosphorylation and subsequent decreases in nuclear p50 and p65 protein levels. Further, the phosphorylation of p38, ERK 1/2 and JNK in LPS-stimulated RAW 264.7 cells was suppressed by CA in a concentration-dependent manner. LPS-induced generation of reactive oxygen species (ROS) was also effectively inhibited by CA. These results suggest that CA exerts anti-inflammatory effects in LPS-stimulated RAW 264.7 macrophages by inhibition of NF-kappaB activation and MAP kinase phosphorylation.
