  Pyrazolopyridinones as functionally selective GABAA ligands

  摘要：

  2,5-Dihydro-3H-pyrazolo[4,3-c]pyridin-3-ones are GABA(A) receptor benzodiazepine binding site ligands, which can exhibit functional selectivity for the alpha(3) subtype over the alpha(1), subtype. SAR studies to optimize this functional selectivity are described. (c) 2005 Elsevier Ltd. All rights reserved.
