Cynaropicrin ist ein Sesquiterpenlacton, das die Freisetzung des Tumornekrosefaktors (TNF-α) mit IC50-Werten von 8,24 bzw. 3,18 μM fÜr murine bzw. menschliche Makrophagenzellen hemmen kann. Cynaropicrin hemmt auch den Anstieg des Knorpelabbaufaktors (MMP13) und unterdrÜckt die NF-κB-SignalÜbertragung.

Cynaropicrin is a sesquiterpene lactone containing an α-methylene-γ-butyrolactone active group, isolated from the Ranunculaceae plant Saussurea lappa. Cynaropicrin has an inhibitory effect on tumor necrosis factor (TNF-α) production and cytokine-induced neutrophil chemokine-1. Cynaropicrin also inhibits the upregulation of the cartilage degradation factor MMP13 and can suppress the NF-κB signaling pathway[1][2].
In vitro, Cynaropicrin (0-40µM; 6h) exhibited no cytotoxicity in RAW264.7 and U937 cells. Cynaropicrin (0-40µM; 24h) inhibited macrophage proliferation in a dose-dependent manner, with IC₅₀ values of 16.3µM in RAW264.7 cells and 17.2µM in U937 cells. Cynaropicrin (0-40µM) inhibited the proliferation of Sup-T1 cells after 24h and 48h of treatment, with IC₅₀ values of 27.5µM and 14.1µM, respectively. Cynaropicrin (0-40µM; 6h) strongly inhibited lipopolysaccharide-induced TNF-α release from both murine and human macrophage cells in a dose-dependent manner with the IC50 values of 8.24 and 3.18µM[1]. Cynaropicrin (1–4µM; 1h) dose-dependently inhibited TNF-α-induced upregulation of MMP13, HIF-2α, and ADAMTS4 mRNA expression and reversed the downregulation of Sox9 mRNA expression in OUMS-27 cells[2].
In vivo, Cynaropicrin (2.5 and 5mg/kg; i.p.; every 2 days for 14 days) decreased tumor volume and weight in mice bearing HCT116 xenografts with minimal toxicity[3].

| Cell experiment [1]: | |
Cell lines | RAW264.7 cells |
Preparation Method | Cynaropicrin was solubilized with vehicle (89.9% propylene glycol, 10% ethanol and 0.1% dimethyl sulfoxide) were diluted with RPMI1640. The final concentration of vehicle was never exceeded 0.05% in the culture medium. Before stimulation with lipopolysaccharide (1µg/ml), RAW264.7 cells were incubated for 18h in 24 well plates under the same conditions. Stimuli and the various concentrations of Cynaropicrin were then added to the wells for 6h. Supernatants were then collected and assayed for TNF-α content. |
Reaction Conditions | 0-40µM；6h |
Applications | Cynaropicrin (0-40µM; 6h) strongly inhibited lipopolysaccharide-induced TNF-α release in a dose-dependent manner. |
| Animal experiment [2]: | |
Animal models | Xenograft mice models bearing HCT116 cells |
Preparation Method | HCT116 cells mixed with an equal volume of PBS and matrigel were implanted in the hind flank of mice (nude mice, female, 5-6 weeks old). Upon attaining an appropriate tumor volume (approximately one-week post-implantation), mice were intraperitoneally injected with Napabucasin (NAPA) or Cynaropicrin (2.5 and 5mg/kg) for 14 days. The mice were given the drug every 2 days and their weight was weighed. |
Dosage form | 2.5 and 5mg/kg; i.p.; every 2 days for 14 days |
Applications | Intraperitoneal administration of Cynaropicrin at doses of 2.5 and 5mg/kg resulted in decreased tumor volume and weight compared to the vehicle group and Napabucasin (10mg/kg) group. LIFR and STAT3 phosphorylation was mechanistically inhibited in the treatment groups. |
