  Synthesis of [18F]-labeled EF3 [2-(2-nitroimidazol-1-yl)-N-(3,3,3-trifluoropropyl)-acetamide], a marker for PET detection of hypoxia

  摘要：

  [F-18]-2-(2-Nitroimidazol-1-yl)-N-(3,3,3-trifluoropropyl)-acetamide ([F-18]-EF3) has been prepared, in 65% chemical yield and 5% radiochemical yield, by coupling 2,3,5,6-tetrafluorophenyl 2-(2-nitroimidazol-1-yl) acetate 1 with [F-18]-3,3,3-trifluoropropylamine 7. This original radiolabelled key-synthon was obtained in 40% overall chemical yield by oxidative [F-18]-fluorodesulfurization of ethyl N-phthalimido-3-aminopropane dithioate 4, followed by deprotection with hydrazine of the resulting [F-18]-N-phthalimido-3,3,3-trifluoropropylamine 5. All the process was performed within 90 min, from the [F-18]-HF production in the cyclotron to the purification of the final target. (C) 2001 Elsevier Science Ltd. All rights reserved.

  The present invention relates to chemical synthesis of radiolabelled perfluorinated bioactive compounds. More particularly, the present invention relates to radiolabelled compounds to be used as indicators for tissue hypoxia. More particularly, the present invention relates to the synthesis and the use of [18F] labelled perfluorinated nitroimidazole compounds having an incorporation of [18F] atoms characterized by a specific radioactivity of the compound comprised between 1 and 30 Ci/mmol, preferably between 1 and 20 Ci/mmol, preferably 1 and 10 Ci/mmol. More particularly to [18F] labelled EF3 or [18F] labelled EF5. The present invention also relates to a method for the detection of tissue hypoxia in a patient comprising introducing an [18F] labelled nitroimidazole compound into said patient, imaging tissue hypoxia in said patient, and, quantifying tissue hypoxia in said patient.
