野菊花内酯对照品 - Reference Information
| biological activity | Handelin is a guaiacol lactone dimer from Chrysanthemum boreale, it has powerful anti-inflammatory activity by down-regulating NF-κB signaling and the production of pro-inflammatory cytokines. |
| Cell Line: | RAW 264.7 cells RAW 264.7 cells |
| Concentration: | 10 μM, 20 μM, 40 μM 10 μM, 20 μM, 40 μM |
| Incubation Time: | 5 hours |
| Result: | iNOS and COX-2 mRNA levels were significantly reduced. The transcriptional activity of NF-κB stimulated with LPS was also suppressed and the LPS-stimulated upregulation of miRNA-155 expression was also suppressed. Suppressed the LPS-induced overexpression of iNOS and COX-2 protein levels in a concentration-dependent manner. Suppressed the induction of pro-inflammatory cytokines TNF-α and IL-1β, and also also suppressed the activation of mitogen-activated protein kinases, including ERK and JNK signaling in LPS-stimulated RAW 264.7 cells. Inhibited acute inflammation in carrageenan-induced paw. The serum level of IL-1β was also inhibited. |
| Animal Model: | Male Sprague-Dawley (SD) rats (150-170 g, 5 weeks old) injected with carrageenan |
| Dosage: | 10 mg/kg, 20 mg/kg |
| Administration: | Oral administration; for 30 mintues |
| Use | The Wild chrysanthemum lactone has the function of clearing away heat and toxic, detumescence and lowering blood pressure. for content determination/identification/pharmacological experiments. |
