Submit ReviewCGP 55845 hydrochloride is a potent, selective GABAB receptor antagonist (IC50 = 5 nM) that prevents agonist binding (pKi = 8.35) and inhibits GABA and glutamate release (pEC50 values are 8.08 and 7.85 respectively). Inhibits GABAB responses to baclofen (IC50 = 130 nM in an isoproterenol assay) and potentiates the hypoglycemic response to glucose in vitro.

CGP-55845 was used to study input of GABA-B receptors into field potential generation in anterior cingulate cortex. Application of 10 nM CGP-55845 increased significantly amplitudes of field potentials and reduced their paired-pulse ratio.
Should be sonicated when dissolved.
Effects of GABAB activation on electrically stimulated dopamine release in the striatum was measured using fast scan cyclic votlammetry. CGP55845 (200nM) nicely reverse Baclofen (30uM) effects on dopamine release.
We typically make a 10mM stock solution in DMSO. Drug seems pretty stable.

Written by Ian Martin, Norman Bowery and Susan Dunn, this review provides a history of the GABA receptor, as well as discussing the structure and function of the various subtypes and the clinical potential of receptor modulators; compounds available from Tocris are listed.
The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
