  Synthesis and in vitro evaluation of small-molecule [18F] labeled gonadotropin-releasing hormone (GnRH) receptor antagonists as potential PET imaging agents for GnRH receptor expression

  摘要：

  Two novel small molecule gonadotropin-releasing hormone (GnRH) receptor antagonists (12 and 13) of the furamide-class were synthesized and evaluated in vitro for their receptor binding affinities for the rat GnRH receptor. Radiolabeling with no carrier added fluorine-18 of the appropriate precursors was investigated in a one-step reaction. LogP (Octanol/PBS pH 7.4) and serum stability of the compounds were investigated. The antagonists showed low nM affinity for the rat GnRH receptor. F-18-radiolabled compounds were obtained in high radiochemical purity (> 95%) and specific activity (> 75 GBq/mu mol). These findings suggest this class of compounds holds promise as potential probes for PET targeting of GnRHreceptor expression. (c) 2014 Elsevier Ltd. All rights reserved.

  Provided herein is technology relating to imaging agents for positron emission tomography (PET) and particularly, but not exclusively, to a gonadotropin-releasing hormone (GnRH) antagonist radiolabeled with positron emitting nuclides and to methods of visualizing GnRH receptors in the central nervous system by PET from administration of such compounds to warm-blooded animals for diagnostic purposes.
