银杏素 用途与合成方法
生物活性
Ginkgetin 是一种从银杏叶中分离得到的双黄酮。Ginkgetin 具有抗肿瘤，抗炎，神经保护，抗真菌的作用。Ginkgetin 也是一种有效的 Wnt 信号抑制剂，IC50 值为 5.92 μM。
靶点
Wnt 5.92 μM (IC 50) |
体外研究
Ginkgetin (2.5-20 μM; 48 h) inhibits the growth of Daoy and D283 cell lines, and induces G
2
/M cell cycle arrest in Daoy cells.
Ginkgetin (20-40 μM; 24 h) significantly activates the apoptosis of osteosarcoma cells in a concentration-dependent manner.
Ginkgetin (10-20 μM; 3-24 h) down-regulated the expression of Wnt target genes without affecting the expression of β-catenin in medulloblastoma cells.
Ginkgetin (1-10 μM; 24 or 48 h) significantly inhibits the VEGF-induced endothelial cell proliferation, migration, and wound recovery in a concentration-dependent manner.
Ginkgetin (5-10 μM; 48 h) induces autophagy responsible for cell death in A549.
Cell Viability Assay
| Cell Line: | Daoy and D283 cell lines |
| Concentration: | 2.5, 5, 10, 20 μM |
| Incubation Time: | 48 hours |
| Result: | Inhibited the cell growth, with IC 50 s of 14.65 and 15.81 μM for Daoy and D283 cells, respectively. |
Apoptosis Analysis
| Cell Line: | Osteosarcoma cells |
| Concentration: | 20, 30, 40 μM |
| Incubation Time: | 24 hours |
| Result: | Markedly induced the apoptosis of osteosarcoma cells in a concentration-dependent manner. |
Cell Cycle Analysis
| Cell Line: | Daoy cells |
| Concentration: | 2.5, 5, 10, 20 μM |
| Incubation Time: | 24 hours |
| Result: | Increased G 2 /M phase, compared with that of control, indicating a G 2 /M cell phase arrest. |
Cell Cycle Analysis
| Cell Line: | Daoy and D283 cell lines |
| Concentration: | 10, 20 μM |
| Incubation Time: | 3, 6, 12, 24 hours |
| Result: | Attenuated the expression of Wnt target genes, Axin2, cyclin D1 and survivin at 20 μM for 24 h in Daoy cells. Unaffected the level of total β-catenin and diminished the level of β-catenin phosphorylation in a time- and concentration-dependent manner. |
体内研究
Ginkgetin (25-100 mg/kg; i.p. 2 hours after the onset of ischemia) exerts anti-inflammatory effects on cerebral ischemia/reperfusion-induced injury in a rat model via the TLR4/NF-κB signaling pathway.
Ginkgetin (30 mg/kg; intragastrically once per day for 42 d) suppresses tumor growth in A549 cells bearing nude mice.
| Animal Model: | Male Sprague-Dawley rats (200-220 g) |
| Dosage: | 25, 50, 100 mg/kg |
| Administration: | I.p. 2 hours after the onset of ischemia |
| Result: | Reduced the neurological deficit score. Suppressed the expression of NF-κB, TLR4 and IκBαin ischemic penumbra cortex, and inhibited the degradation of IκBα. Decreased the expressions of ICAM-1, COX-2, and iNOS. Downregulated downstream inflammatory factor PGE2 and TNF-α expression. Decreased IL-1β, IL-6, IL-8, and IL-10 protein expression. |
