Pyrazolopyridinones as functionally selective GABAA ligands

2,5-Dihydro-3H-pyrazolo[4,3-c]pyridin-3-ones are GABAA receptor benzodiazepine binding site ligands, which can exhibit functional selectivity for the α3 subtype over the α1 subtype. SAR studies to optimize this functional

Pyrazolo-pyridine derivatives as ligands for GABA receptors

Pyrazolo[4,3-c]pyridin-3-one derivatives substituted at the 2-position by an optionally substituted aryl or heteroaryl moiety, and having pendant substituents at the 7-position and optionally also at the 6-position, are selective ligands for GABAAreceptors, particularly having high affinity for the α2 and/or α3 subunit, and are useful in the treatment and/or prevention of disorders of the central nervous system, including anxiety and convulsions.
