Bilobalide (Synonyms: (-)-Bilobalide)

Cat. No.: HY-N0076 Purity: ≥98.0%
Handling Instructions

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.

Description

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].

IC50 & Target

Human Endogenous Metabolite

 

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
