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

| In Vitro | Bicuculline methobromide (1 μM and 3 μM) attains the maximal response of GABA. Bicuculline methobromide appears to shift the dose–response curves of GABA in parallel to the right without decreasing GABA maximal response, suggesting that it is a competitive antagonist at human α1β2γ2L GABAA receptors expressed in Xenopus oocytes[3]. Bicuculline methobromide (1-100 μM; 2 min; applied as outside-out patches) potently blocks both Apamin (HY-P0256)-sensitive small-conductance calcium-activated potassium channels (SK2) currents and Apamin-insensitive SK1 currents in Xenopus oocytes[4]. |
| In Vivo | Bicuculline methobromide (subcutaneous injection, 1.25-3 mg/kg) can cause clonus-tonic convulsions in a dose-dependent manner in mice and these convulsions are enhanced by injection of the μ-opioid agonist morphine[1]. Bicuculline methobromide (subcutaneous injection, 1.5-3.2 mg/kg) induces male Swiss S mice generalized seizures with a CD50 (convulsant dose) of 2.2 mg/kg for clonus and CD50 of 2.4 mg/kg for tonus. Seizures induced by Bicuculline at the dose of 3.2 mg/kg can be blocked by pretreatment (i.p.) with the NMDA antagonists MK-801, CPP and CGS 19755[2]. |
