Abstract:
PURPOSE:The future significance of peptide radiopharmaceuticals in diagnostic imaging with PET will be dependent on methodological aspects, as well as other requirements such as availability of the radionuclide and cost-effectiveness of its production. The aim of this study was to evaluate whether recent improvements in the modification of peptide pharmacokinetics by carbohydration may open a niche for the use of 11C-labelled peptide receptor binding tracers. METHODS:A carbohydrated analogue of Tyr3-octreotate was used as a clinically relevant peptide. Oxime-mediated coupling between 4-[11C]methoxy-benzaldehyde and an aminooxy-conjugated peptide precursor provided the 11C-labelled peptide in 21+/-5% decay-corrected yield (n=4) in a synthesis time of about 1 h. RESULTS:In rat pancreas carcinoma xenografted mice, the compound displayed predominant and fast renal clearance combined with high tumour uptake (18.5+/-2.8% ID/g) at 30 min post injection. Corresponding values for kidney, liver and intestine were 18.5+/-2.4% ID/g, 3.2+/-0.5% ID/g and 2.1+/-0.3% ID/g, respectively. In a PET study with xenografted mice, the tumour (0.2-0.3 g) was clearly delineated as early as 20 min after injection. Somatostatin receptor (sstr)-specific uptake was demonstrated by reduction of tumour uptake to 20% of control by co-injection of TOC (0.4 mg/kg; 30 min p.i.). CONCLUSION:A 11C-labelled octreotate derivative has been prepared which shows suitable pharmacokinetics for in vivo imaging of sstr-overexpressing tumours and thus represents the first proof of principle for the potential of 11C-labelled peptides in tumour imaging.
