ABSTRACT The present invention concerns compositions comprising and methods of identification and use of imaging agents. The imaging agents comprise a growth hormone secretagogues having a conjugated fluoride. The imaging agents of the present invention may be used for detection, diagnosis and/or staging of prostate or other forms of cancer, and may also be used for cardiac disease.

The versatile 18F-labeled prosthetic group, 4-nitrophenyl 2-[18F]fluoropropionate ([18F]NFP), was synthesized in a single step in 45 min from 4-nitrophenyl 2-bromopropionate, with a decay corrected radiochemical yield of 26.2% ± 2.2%. Employing this improved synthesis of [18F]NFP, [18F]GalactoRGD - the current 'gold standard' tracer for imaging the expression of αVβ 3 integrin - was prepared with high specific activity in 90 min and 20% decay corrected radiochemical yield from [18F]fluoride. 4-Nitrophenyl 2-[18F]fluoropropionate ([18F]NFP), was synthesized in a single radiochemical step in 45 minutes and 26% d.c. radiochemical yield from 4-nitrophenyl 2-bromopropionate. Employing this improved synthesis of [18F]NFP, [18F]GalactoRGD was prepared with high specific activity in 90 minutes and 20% d.c. radiochemical yield from [18F]fluoride. Copyright
