    Scientific background

    CGS 20625 is a synthetic compound that acts as a potent and selective partial agonist of GABA(A) receptors.

    CGS 20625 is a pyrazolopyridine compound that possesses anxiolytic and anticonvulsant characteristics. It binds to a specific recognition site on GABAA receptors containing α1, α2, α3, and α5 subunits1-3.

    GABA(A) receptors are members of the Cys-loop superfamily of ligand-gated ion channels. They mediate GABA actions, a major inhibitory neurotransmitter, throughout the central nervous system where it plays an important role in inhibiting cell excitation. GABA(A) receptors are a major target for antiseizure drugs4.
