藏红花醛 用途与合成方法
藏红花醛呈黄色液体状，溶于乙醇等有机溶剂。
藏红花醛可由藏红花中的苦味素一苦藏花素在酸中水解取得，或由β-环柠檬醛或a-环香叶酸用氧化硒催化脱氢制得。
Safranal 是藏红花 (Crocus sativus) 的主要成分，具有口服活性，是这种香料的独特香气来源。Safranal 具有神经保护和抗炎作用，并有用于帕金森氏病的研究潜力。
Safranal (10-50 μM; for 1 h) dose-dependently decreases LPS-induced iNOS and COX-2 levels in both RAW264.7 cells and BMDMs.
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.
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.
Western Blot Analysis
| 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
| 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. |
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.
| Animal Model: | Female BALB/c mice (18-20 g) (DSS-induced colitis mice) |
| 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. |
