  Synthesis of [18F]Ro41-0960, a potent catechol-O-methyltransferase inhibitor, for PET studies

  摘要：

  Ro41-0960 (3,4-dihydroxy-5-nitro-2'-fluorobenzophene) is a potent, fluorine containing COMT inhibitor. In order to map catechol-O-methyltransferase (COMT) in vivo with PET, no-carrier-added [F-18]Ro41-0960 was synthesized by the nucleophilic aromatic substitution of [F-18]fluoride for 2'-nitro on 3,4-dimeihoxy-5,2'-dinitrobenzophenone, followed by hydrolysis with HBr. During the course of this study it was found that [F-18]fluoromethane ([F-18]CH3F) was generated as the side product of nucleophilic aromatic substitution reaction. Various precursors with different hydroxyl protecting groups were then investigated for the effects on this side reaction.
