Welcome to our next molecule of the month 2024 - TE-TDDPN
A relatively complex synthesis complicates use of the popular opioid receptor radiotracer 6-O-(2-[18F]fluoroethyl)-6-O-desmethyl-diprenorphine ([18F]FE-DPN) for positron emission tomography (PET) studies. To simplify access to [18F]FE-DPN, the novel precursor TE-TDDPN was developed for direct one-pot, two-step nucleophilic radiosynthesis of the PET tracer [1]. Several groups demonstrated successful application of the new precursor [2,3,4]. In honour of the memory of Professor Gjermund Henriksen, his life work, and his many contributions to the field of PET imaging of opioid receptors, TE-TDDPN was named as “Henriksen precursor”.
