Cynaropicrin (C09-1119-753)

Cynaropicrin is a sesquiterpene lactone which can inhibit tumor necrosis factor ( TNF-α ) release with IC 50 s of 8.24 and 3.18 μM for murine and human macrophage cells, respectively. Cynaropicrin also inhibits the increase of cartilage degradation factor ( MMP13 ) and suppresses NF-κB signaling.In VitroCynaropicrin strongly inhibits lipopolysaccharide-induced TNF-α release from either murine or human macrophage cells in a dose-dependent manner with the IC 50 values of 8.24 and 3.18 μM, respectively. Cynaropicrin shows significant inhibitory effects toward all mitogenic signals with the IC 50 values of 1.20 (concanavalin A), 1.02 (phytohemagglutinin) and 0.90 μM (lipopolysaccharide), respectively. Cynaropicrin suppresses CTLL-2 cell proliferation in a dose-dependent manner and the 50% inhibitory concentration (IC 50 ) of Cynaropicrin for CTLL-2 cell growth is 0.91 μM. The increased mRNA expression of MMP13 induced by TNF-α is similarly inhibited in a concentration-dependent manner by Cynaropicrin. The increased mRNA expression of HIF-2α induced by IL-1β in SW1353 is inhibited in a concentration-dependent manner by Cynaropicrin. MCE has not independently confirmed the accuracy of these methods.
