General description

Bicuculline is a phthalide isoquinoline alkaloid, which is extracted from Dicentra cucullaria. It acts as an acetylcholinesterase inhibitor. Bicuculline inhibits slow afterhyperpolarization (AHP).

Application

1(S),9(R)-(-)-Bicuculline methiodide has been used as a gamma-aminobutyric acid (GABA) antagonist to block inhibition in the semicoronal slices. It has also been used for the preparation of organotypic hippocampal slice cultures (OHSCs).

Biochem/physiol Actions

(-)-Bicuculline methiodide is a GABAA receptor antagonist, which acts as a competitive inhibitor of GABA ligand binding to the receptor.
