背景说明 |
Bilobalide是存在于银杏中的生物活性物,具有神经保护活性。 |
生物活性 |
Bilobalide, a sesquiterpene trilactone constituent of Ginkgo biloba, inhibits the NMDA-induced efflux of choline with an IC50 value of 2.3 μM. Bilobalide prevents apoptosis through activation of the PI3K/Akt pathway in SH-SY5Y cells. Exerts protective and trophic effects on neurons[1][2]. |
In Vitro |
Bilobalide (1-100 μM) completely suppresses the NMDA-evoked release of choline in a concentration-dependent manner with IC50 value of 2.3 μM[1].Bilobalide (1, 5 and 10 μM) alone for 24 h does not affect cell viability of SH-SY5Y cells. Pre-treatment of cells with Bilobalide concentration-dependently prevents Aβ 1-42-, H2O2- and serum deprivation-induced decrease of cell viability, with the best protective effect obtained at 10 μM[2].Bilobalide (5 and 10 μM; 24 h) treatment dose-dependently increases levels of p-Akt (Ser473 and Thr308) in SH-SY5Y cells[2].Western Blot Analysis:Cell Line:SH-SY5Y cells;Concentration: 5 and 10 μM;Incubation Time:24 hours;Result:Induced a significant increase in levels of p-Akt (Ser473 and Thr308). |
In Vivo |
Bilobalide (20 mg/kg) completely suppresses the NMDA-induced release of choline in vivo while basal choline levels were not significantly affected. NMDA causes a release of choline in vivo when infused into the hippocampus of freely moving rats by retrograde dialysis. Bilobalide (20 mg/kg i.p.) completely inhibits the effect induced by NMDA[1].Animal Model: Male Wistar rats (250-350 g)[1];Dosage: 20 mg/kg;Administration:I.p. injection 60 min before NMDA infusion;Result:Lowered basal choline efflux only slightly (by 7%) but fully antagonized the NMDA-induced increase of choline release. The convulsive effect of NMDA was almost completely suppressed. |
