Handelin (Compound 1; 10-40 μM; RAW 264.7 cells) treatment suppresses the LPS-induced (1 μg/mL) overexpression of iNOS and COX-2 protein levels in a concentration-dependent manner. Handelin also suppresseS the induction of pro-inflammatory cytokines TNF-α and IL-1β in LPS-stimulated RAW 264.7 cells. Handelin also suppresses the activation of mitogen-activated protein kinases, including ERK and JNK signaling.
Handelin (Compound 1; 10-40 μM; RAW 264.7 cells) treatment significantly reduces the iNOS and COX-2 mRNA levels in LPS- stimulated RAW 264.7 cells. The transcriptional activity of NF-κB stimulated with LPS is also suppressed by Handelin. In addition, the LPS-stimulated upregulation of miRNA-155 expression is suppressed by Handelin.
RT-PCR
| Cell Line: | RAW 264.7 cells |
| Concentration: | 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. |
Western Blot Analysis

| Concentration: | 10 μM, 20 μM, 40 μM |
| Incubation Time: | |
| Result: | 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. |
Handelin (Compound 1; 10-20 mg/kg; oral administration; for 30 mintues; male Sprague-Dawley rats) treatment inhibits acute inflammation in carrageenan-induced paw edema model. The serum level of IL-1β is also inhibited by Handelin in a carrageenan-induced paw edema model .
| 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 |
| Result: | Inhibited acute inflammation in carrageenan-induced paw. The serum level of IL-1β was also inhibited. |
