Product overview

  • Name
    CGP55845 hydrochloride
  • Short description
    Potent, selective GABAB receptor antagonist
  • Biological description

    CGP55845 hydrochloride is a potent and selective GABAB receptor antagonist (IC50 = 5 nM). It inhibits [3H]CGP 27492 binding (pKi = 8.35).

    CGP55845 hydrochloride inhibits GABA and glutamate release and inhibits GABAB receptor responses to baclofen (IC50 = 130 nM in an isoproterenol assay).

    It enhances responses to hypoglycaemia and shows convulsive actions at high doses.
