Cover Story: G-protein-coupled receptors (GPCRs) represent valid molecular targets for directing peptide radioligands to malignant lesions. Diagnosis (γ-emitters: SPECT, β+-emitters: PET) and therapy (α, β-, Auger e- emitters: PRRT) are combined in a new promising “radiotheranostics” approach. Radiolabeled somatostatin analogs are widely used in neuroendocrine tumor patients, whereas peptide radioligands targeting other GPCRs in different tumors include bombesin, gastrin and exendin analogs. A recent switch from internalizing GPCR agonists to antagonists led to better pharmacokinetics and higher biosafety. GPCR antagonists do not activate their target receptor and do not elicit acute adverse effects when injected into patients. We herein discuss the challenges and opportunities of modern peptide radiotheranostics, focusing on GPCR antagonists. View this paper
