General description

Bicuculline is a convulsant alkaloid. It was originally isolated from the plant Dicentra cucullaria.

Application

Bicuculline has been used:
  • as a compound to compare pharmacodynamics and network activity profiles of conolidine/cannabidiol
  • to study the effects of chronic caffeine administration on the function of GABAA receptor
  • to isolate N-methyl-D-aspartate receptor (NMDAR)-specific evoked and miniature excitatory postsynaptic currents (eEPSCs and mEPSCs) in neurons of rats

Biochem/physiol Actions

(+)-Bicuculline acts as a competitive inhibitor of GABA liganding binding to the receptor.
(+)-Bicuculline is a GABAA receptor antagonist.
