IC₅₀ & Target

Human Endogenous Metabolite

All Endogenous Metabolite Isoforms :

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].

MedChemExpress (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].

MedChemExpress (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.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
