生物活性

Cynaropicrin 是一种倍半萜内酯，可以抑制肿瘤坏死因子 (TNF-α) 的释放，在鼠和人巨噬细胞的 IC50 值分别为 8.24 和 3.18 μM。 Cynaropicrin 也抑制软骨降解因子 (MMP13) 的增加并抑制 NF-κB 的信号传导。

靶点

MMP13 NF-κB TNF-α

体外研究

Cynaropicrin 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.
