产品详情
生物活性:
Bicuculline methiodide is a potent GABA(A) receptors blocker. Bicuculline methiodide alters membrane properties and firing pattern. Bicuculline methiodide reduces the Apamin-sensitive afterhyperpolarization, while Apamin is a toxin isolated from bee venom to block small conductance Ca2+ -activated K+ channels. Bicuculline methiodide facilitates burst firing via blocking apamin-sensitive Ca2+ -activated K+ current.

体外研究:
Bicuculline methiodide (30 μM) 促进 N-甲基-d-天冬氨酸 (NMDA) 刺激,促进多巴胺神经元的爆发性放电。研究表明,反奖励中枢外侧缰核(LHb)的簇状放电是抑郁症发生的充分条件。LHb神经元常分为三类:沉默型(silent), 强直放电型(tonic-firing),簇状放电型(burst-firing)。
