说明

一般說明

Picrotoxin is isolated from moonseed family, Menispermaceae. It is a stimulant and may cause convulsions. It is an allosteric modulator of γ-aminobutyric acid (GABA_A) receptor.

應用

Picrotoxin has been used:

• as non-competitive antagonist for the γ-aminobutyric acid (GABA_A) for studying synchronized burst (SB) dynamics
• as a component of extracellular saline for blocking glutamate and acetylcholine receptors in neurons
• as a component of artificial cerebrospinal fluid (ACSF) for voltage-clamp recordings studies in dissociated cortical neurons

生化／生理作用

Picrotoxin is a competitive inhibitor of glycine receptors (GlyRs). It is a non-competitive antagonist, which binds to ligand bounded γ-aminobutyric acid (GABAA) receptor.

GABA_A receptor antagonist; binds to the GABA receptor-linked Cl⁻ channel.
