(-)-Bicucullinemethiodide

The Uses of (-)-Bicucullinemethiodide

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).

What are the applications of Application

(?)-Bicuculline methiodide is a N-methylated derivative of the GABAA antagonist (+)-bicuculline

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).

Biological Activity

Methiodide form of classical GABA A receptor antagonist (+)-bicuculline ([R-(R*,S*)]-6-(5,6,7,8-Tetrahydro-6-methyl-1,3-dioxolo[4,5-g]isoquinolin-5-yl)furo[3,4-e]-1,3-benzodioxol-8(6H)-one ). More water-soluble and stable. Non-GABA receptor-mediated actions reported, including actions on calcium-dependent potassium channels.

Biochem/physiol Actions

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