Imidazo[1,2-a]pyrimidines as functionally selective GABAA ligands
摘要:
Imidazo[1,2-a]pyrimidines 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) 2006 Elsevier Ltd. All rights reserved.
