银杏素 用途与合成方法

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。

Wnt

5.92 μM (IC 50 )

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.

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.
