Synthesis of high-specific-radioactivity 4- and 6-[18F]fluorometaraminol- PET tracers for the adrenergic nervous system of the heart
Fluorine-18 (t12:109.8min)-labeled analogues of metaraminol, 4-[18F]FMR ((1R,2S)-2-amino-1-(4-[18F]fluoro-3-hydroxy phenyl)-1-propanol) and 6-[18F]FMR ((1R,2S)-2-amino-1-(2-[18F]fluoro-5-hydroxyphenyl)-1-propanol), were synthesized as new positron-emission-tomography (PET) tracers for mapping cardiac adrenergic nerve terminals.
