Abstract

L'invention concerne des compositions destinées à réduire le technétium pour former des ligands marqués au technétium, qui comprennent un substrat acceptable du point de vue pharmacologique auquel est lié un complexe réducteur dont le potentiel d'oxydo-réduction est suffisant pour réduire le technétium à partir du degré d'oxydation + 7. Le complexe réducteur comprend de préférence un agent réducteur du technétium et un ligand chélateur correspondant. Des ligands marqués au technétium sont préparés par mélange de ces ligands avec un pertechnétate en présence du réducteur de l'invention, puis séparation du réducteur et du ligand marqué résultant. On peut préparer de la sorte des ligands marqués au technétium qui sont sensiblement dépourvus de l'agent réducteur utilisé dans leur préparation. Applications radiopharmaceutiques.
