Bicuculline ((+)-Bicuculline; d-Bicuculline) methochloride is a selective GABAA receptor antagonist with an IC50 value of 3 μM. Bicuculline methochloride induces clonic tonic convulsions in mammals and can also be used to block Ca2+ activated potassium channels. Bicuculline methochloride can be used in studies of epilepsy and other related psychiatric disorders[1][2].

In Vitro	Bicuculline 甲基氯化物 (1 μM和3 μM) 达到 GABA 的最大反应。Bicuculline 甲基氯化物似乎使 GABA的剂量-反应曲线向右平行移动，而不降低 GABA 的最大反应，这表明它在表达人 α1β2γ2L GABAA 受体的爪蟾卵母细胞中是一种竞争性拮抗剂[3]。 Bicuculline 甲基氯化物 (1-100 μM; 2 分钟; 应用于外部贴片) 有效地阻断了爪蟾卵母细胞中，对 Apamin (HY-P0256) 敏感的小导钙活化钾通道 (SK2) 电流和对 Apamin 不敏感的 SK1 电流[4]。
In Vivo	Bicuculline 甲基氯化物 (1.25-3 mg/kg; 皮下注射) 能以剂量依赖的方式引起小鼠的阵挛性抽搐，这些抽搐会因注射 μ-阿片受体激动剂吗啡而加强[1]。 Bicuculline 甲基氯化物 (1.5-3.2 mg/kg; 皮下注射) 诱发小鼠全身性癫痫发作，对 clonus 的CD50 (惊厥剂量) 为 2.2 mg/kg，对 tonus 的 CD50为 2.4 mg/kg。 Bicuculline 甲基氯化物在3.2 mg/kg 的剂量下诱发的癫痫发作，可以通过 NMDA 拮抗剂 MK-801、CPP 和 CGS 19755 的预处理 (静脉注射) 来阻断[2]。
