（+）-Bicuculline 485-49-4
| 產品描述 | |
| 描述 | (+)-Bicuculline is an antagonist of the GABAA receptor. (+)-Bicuculline is the parent compound of the water soluble N-methyl derivatives (-)-Bicuculline methiodide and (-)-Bicuculline methobromide . Antagonism of the GABAA receptor by (+)-Bicuculline blocks the neurotransmission inhibition function of the GABA system in vitro. |
| 應用 | A GABA A receptor antagonist |
| 純度 | ≥98% |
| 儲存/保存方法 | Store at -20℃ for one year（Powder）；Store at 2-4℃ for two weeks；Store at -20℃ for six months after dissolution. |

| 生物活性 | |
| 靶點 | GABAA receptor |
| In vitro(體外研究) | (+)-Bicuculline (1-100μM) dose-dependently inhibits the Cl- conductance generated by 40 μM GABA. (+)-Bicuculline also inhibits the agonist action of GABA at 40 μM at α1β2γ2L receptors. (+)-Bicuculline at 1 and 3 μM increases GABA EC50 values 1.6 times (41.0-67.0 μM) and 3.6 times (36.1-129.0 μM), respectively. Atα1β2γ2L GABAA receptors, (+)-bicuculline displays the general property of the competitive antagonist, producing a parallel shift of GABA concentration-effect curves and having no effect on the maximal response of GABA. In addition to being a potent GABAA receptor antagonist, (+)-bicuculine also blocks Ca2+-activated potassium channels. |
