生物活性
Ginkgolide B (BN-52021), an important active terpenoid from Ginkgo biloba leaves, is reported to increase cell viability and decrease cell apoptosis. IC50 value: Target: In vitro: Ginkgolide B (0.2 or 0.4 μg/ml) was added to the culture medium in vitro led to increases in cell viability and decreases in the number of hippocampal cells undergoing AAPH-induced apoptosis [1]. Ginkgolide B caused a dose-related protection against dysrhythmias; the antiarrhythmic effect of ginkgolide B was comparable to that of diltiazem and superior to the activity of metoprolol. Ginkgolide B can presumably prevent the re-entry mechanism involved in the development of ischemia-induced rhythm disturbances [2]. In vivo: Oral administration of ginkgolide B (2 mg/kg/day, p.o.) caused a significant increase in cell viability and a highly significant decrease in the numbers of both spontaneously occurring and AAPH-induced apoptoses.

Human Endogenous Metabolite
体外研究 (In Vitro)
Ginkgolide A (BN-52020) is a highly active PAF antagonist cage molecule that is isolated from the leaves of the Ginkgo biloba tree. Shows potential in a wide variety of inflammatory and immunological disorders. Ginkgolide A (BN-52020) failed to affect apoptotic damage neither in serum-deprived nor in staurosporine-treated neurons[2].

体外研究 (In Vitro)
Ginkgolide C (3-100 μM) has no significant effect on 3T3-L1 cell viability, but suppresses adipogenesis in 3T3-L1 cells followling 24 h treatment. Ginkgolide C (10-100 μM) significantly suppresses lipid accumulation compared with the control group and also significantly promotes glycerol release in 3T3-L1 adipocytes. Ginkgolide C suppresses PPAR-α and PPAR-γ expression and decreases C/EBPα, C/EBPβ, and SREBP-1c expression in differentiated 3T3-L1 adipocytes. In addition, Ginkgolide C (3-100 μM) suppress adipogenesis-related protein (FAS, LPL, and aP2) and mRNA expression in a dose-dependent manner in differentiated 3T3-L1 adipocytes. Ginkgolide C (3-100 μM) also significantly promotes Sirt1 production and increases phosphorylation of AMPKα and ACC-1 in a concentration-dependent manner[1]. Ginkgolide C (1, 10, 50, 100, 500 mM) significantly reduces the collagen (10 mg/mL)-stimulated rat platelet aggregation in a dose-dependent manner. Ginkgolide C (50, 100 mM) causes pro-MMP-9 (92-kDa) to form an activated MMP-9 (86-kDa) in collagen-stimulated platelets[2].

Cell Assay [1]
3T3-L1 cells are treated with various concentrations of ginkgolide C in 96-well plates for 24 h. Cell viability is analyzed by the MTT assay. The culture medium is removed, and the cells are incubated with 100 μL MTT solution (5 mg/mL) for 4 h at 37°C. After plates are washed, isopropanol is added to dissolve formazone crystals, followed by absorbance detection with a spectrophotometer at 570 nm[1].
