  Synthesis of [1-11C]-2-octynoic acid, [1-11C]-2-decynoic acid and [1-11C]-3-(R,S)-methylocatanoic acid as potential markers for PET studies of fatty acid metabolism

  摘要：

  [1-C-11]-2-Octynoic acid, [1-C-11]-2-decynoic acid and [1-C-11]-3-(R,S)-methyloctanoic acid have been synthesized in order to evaluate these compounds as PET (Positron Emission Tomography) tracers for imaging in vivo medium-chain acyl-CoA dehydrogenase and medium-chain fatty acid utilization. The synthesis was performed by the Grignard reaction between alkylmagnesium bromides and [C-11]CO2. The radiochemical yields of [1-C-11]-2-octynoic acid, [1-C-11]-2-decynoic acid, and [1-C-11]-3-(R,S)-methyloctanoic acid were 10, 7 and 1% based on the [C-11]CO2 used respectively. Radiochemical purity was >99% in all cases.
