  Imidazo[1,2-b][1,2,4]triazines as α2/α3 subtype selective GABAA agonists for the treatment of anxiety

  摘要：

  Imidazo[1,2-a]pyrimidines and imidazo[1,2-b][1,2,4]triazines are ligands for the benzodiazepine binding site of GABA(A) receptors that are functionally selective for the alpha 2/alpha 3 subtypes over the alpha 1 subtype. SAR studies to optimise this functional selectivity, pharmacokinetic and behavioural data are described. (C) 2006 Elsevier Ltd. All rights reserved.
