| Bioactivity | Cynaropicrin is a sesquiterpene lactone which can inhibit tumor necrosis factor (TNF-α) release with IC50s 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. |
| Invitro | Cynaropicrin strongly inhibits lipopolysaccharide-induced TNF-α release from either murine or human macrophage cells in a dose-dependent manner with the IC50 values of 8.24 and 3.18 μM, respectively. Cynaropicrin shows significant inhibitory effects toward all mitogenic signals with the IC50 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 (IC50) of Cynaropicrin for CTLL-2 cell growth is 0.91 μM[1]. 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[2]. |
