Radiosynthesis and preliminary biological evaluation of N-(2-[18F]fluoropropionyl)-L-glutamine as a PET tracer for tumor imaging.

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.
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
In this study, radiosynthesis and biological evaluation of a new [18F]labeled glutamine analogue, N-(2-[18F]fluoropropionyl)-L-glutamine ([18F]FPGLN) for tumor PET imaging are performed. [18F]FPGLN was synthesized via a two-step reaction sequence from 4-nitrophenyl-2-[18F]fluoropropionate ([18F]NFP) with a decay-corrected yield of 30 ± 5% (n=10) and a specific activity of 48 ± 10 GBq/μmol after 125 ± 5 min of radiosynthesis. The biodistribution of [18F]FPGLN was determined in normal Kunming mice and high uptake of [18F]FPGLN was observed within the kidneys and quickly excreted through the urinary bladder. In vitro cell experiments showed that [18F]FPGLN was primarily transported by Na+-dependent system XAG- and was not incorporated into proteins. [18F]FPGLN displayed better stability in vitro than that in vivo. PET/CT studies revealed that intense accumulation of [18F]FPGLN were shown in human SPC-A-1 lung adenocarcinoma and PC-3 prostate cancer xenografts. The results support that [18F]FPGLN seems to be a possible PET tracer for tumor imaging.
