体外研究 (In Vitro) |
Safranal (10-50 μM; for 1 h) dose-dependently decreases LPS-induced iNOS and COX-2 levels in both RAW264.7 cells and BMDMs[1]. Safranal (10-50 μM; for 1 h) inhibits cytokine IL-6 and TNF-α production and mRNA expression in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells[1]. Safranal (10, 50 μM; for 1 h followed by stimulation with 1 μg/ml of LPS for 30 min) inhibits the nuclear translocation of NF-κB and AP-1 in lipopolysaccharide (LPS)-stimulated RAW264.7 cells[1].
Western Blot Analysis[1]
Cell Line: |
RAW264.7 cells and bone marrow-derived macrophages (BMDMs) |
Concentration: |
10, 50 μM |
Incubation Time: |
For 1 h prior to lipopolysaccharide (LPS) stimulation (1 μg/ml) |
Result: |
Dose-dependently decreased LPS-induced iNOS and COX-2 levels in both RAW264.7 cells and BMDMs. Inhibited the phosphorylation of MAPK pathway proteins extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38. Inhibited NF-κB pathway proteins IKKα/β and IκBα and the degradation of IκBα. |
RT-PCR[1]
Cell Line: |
RAW 264.7 cells |
Concentration: |
10, 50 μM |
Incubation Time: |
For 1 h followed by stimulation with LPS (1 μg/ml) for 24 h |
Result: |
Inhibited cytokine IL-6 and TNF-α production and mRNA expression in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. |

体内研究 (In Vivo) |
Safranal (200-500 mg/kg; PO; for 7 days) causes a slight restoration of colon length and percentage of weight loss, and the DAI score is significantly low[1].
Animal Model: |
Female BALB/c mice (18-20 g) (DSS-induced colitis mice)[1] |
Dosage: |
200, 500 mg/kg |
Administration: |
PO; for 7 days |
Result: |
Caused a slight restoration of colon length and percentage of weight loss, and the DAI score is significantly low. |
