Abstract

L'invention concerne des indoles à substitution 5-hétéroaryle possédant une affinité importante pour les récepteurs adrénergiques α1. De ce fait, ces composés sont considérés utiles pour traiter des troubles ou des maladies sensibles aux antagonistes du récepteur adrénergique α1. Etant donné, également, que quelques uns de ces composés sont des ligands sélectifs du récepteur adrénergique α1, ils peuvent être particulièrement utiles en tant que ligands de PET ou CPECT.
