说明

一般描述

Bicuculline is a phthalide isoquinoline alkaloid, which is extracted from Dicentra cucullaria.[1] It acts as an acetylcholinesterase inhibitor.[2] Bicuculline inhibits slow afterhyperpolarization (AHP).[3]

应用

1(S),9(R)-(-)-Bicuculline methiodide has been used as a gamma-aminobutyric acid (GABA) antagonist to block inhibition in the semicoronal slices.[4] It has also been used for the preparation of organotypic hippocampal slice cultures (OHSCs).[5]

生化/生理作用

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