Indium-labeled macrocyclic conjugates of naltrindole: High-affinity radioligands for in vivo studies of peripheral δ opioid receptors

Article abstract of DOI:10.1021/jm0700013

We have identified a series of hydrophilic indium-labeled DOTA and DO3A conjugates of naltrindole (NTI) that are suited to in vivo studies of peripheral δ opioid receptors. Indium(III) complexes, linked to the indole nitrogen of NTI by six- to nine-atom s
