Product Introduction

Bioactivity
Description
Bicuculline ((+)-Bicuculline) is a light-sensitive competitive antagonist of GABAA receptors, originally identified in 1932 from plant alkaloid extracts, and isolated from Dicentra cucullaria, Adlumia fungosa, Fumariaceae, and various Corydalis species.
Targets&IC50
GABAA receptor:2 μM
In vivo
(+)-Bicuculline, at concentrations of 1/3 μM, increased the EC50 of gamma-aminobutyric acid (GABA) by 1.6 times (41.0-67.0 μM) and by 3.6 times (36.1-129.0 μM), respectively. This compound also dose-dependently inhibited the Cl- conductance induced by GABA (40 μM) in the range of 1-100 μM. In addition, (+)-Bicuculline inhibited the agonistic effects of GABA (40 μM) on the α1β2γ2L receptor, functioning as an antagonist of the α1β2γ2L GABAA receptor. This action caused a parallel shift in the concentration-effect curve of GABA without affecting its maximum response. Furthermore, (+)-Bicuculline also exhibited inhibitory effects on Ca2+-activated potassium channels.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
