1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

We have used the well-accepted and easily available 2-[(18)F]fluoro-2-deoxyglucose ([(18)F]FDG) positron emission tomography (PET) tracer as a prosthetic group for synthesis of (18)F-labeled peptides. We herein report the synthesis of [(18)F]FDG-RGD ((18)F labeled linear RGD) and [(18)F]FDG-cyclo(RGD(D)YK) ((18)F labeled cyclic RGD) as examples of the use of [(18)F]FDG. We have successfully prepared [(18)F]FDG-RGD and [(18)F]FDG-cyclo(RGD(D)YK) in 27.5% and 41% radiochemical yields (decay corrected) respectively. The receptor binding affinity study of FDG-cyclo(RGD(D)YK) for integrin alpha(v)beta(3), using alpha(v)beta(3) positive U87MG cells confirmed a competitive displacement with (125)I-echistatin as a radioligand. The IC(50) value for FDG-cyclo(RGD(D)YK) was determined to be 0.67 +/- 0.19 muM. High-contrast small animal PET images with relatively moderate tumor uptake were observed for [(18)F]FDG-RGD and [(18)F]FDG-cyclo(RGD(D)YK) as PET probes in xenograft models expressing alpha(v)beta(3) integrin. In conclusion, we have successfully used [(18)F]FDG as a prosthetic group to prepare (18)F]FDG-RGD and [(18)F]FDG-cyclic[RGD(D)YK] based on a simple one-step radiosynthesis. The one-step radiosynthesis methodology consists of chemoselective oxime formation between an aminooxy-functionalized peptide and [(18)F]FDG. The results have implications for radiolabeling of other macromolecules and would lead to a very simple strategy for routine preclinical and clinical use.
