Radiochemical syntheses of 2-deoxy-2-[18F]fluoro-maltose ([18F]FDM) and 2-deoxy-2-[18F]fluoro-sakebiose ([18F]FSK). (A) Synthesis of the β-d-glucose-1-phosphate (βGlc1-P) precursor starting from acetobromo-α-d-glucose (S1). (B) Enzymatic radiosynthesis of [18F]FDM and [18F]FSK from 2-deoxy-2-[18F]fluoro-d-glucose [18F]FDG and βGlc1-P using maltose phosphorylase. (C) Radio HPLC analysis of crude products using a YMC-Pack Polyamine II column.
