  Syntheses, Biological Evaluation, and Molecular Modeling of ¹⁸F-Labeled 4-Anilidopiperidines as μ-Opioid Receptor Imaging Agents

  摘要：

  The synthesis, evaluation, and molecular modeling of a series of F-18-labeled 4-anilidopiperidines with high affinities for they-opioid receptor (mu-OR) are reported. On the basis of the high brain uptake and selective retention in brain regions that contain a high concentration of they-OR, combined with a good metabolic stability, [F-18]fluoro-pentyl carfentanil ([F-18]4) and 2-(+/-)[F-18]-fluoropropyl-sufentanil ([F-18]6) were selected as the lead compounds for further evaluation. The binding affinity to the human mu-OR was 0.74 and 0.13 nM for [F-18]4 and [F-18]6, respectively. In vitro autoradiography of [F-18]4 and [F-18]6 on rat brain sections produced patterns in accordance with the known distribution of mu-OR expression. Structure-activity relationships of the fluorinated compounds are discussed with respect to the interaction with an activated-state model of the mu-OR. Taken together, the in vivo and in vitro data indicate that [F-18]4 and [F-18]6 hold promise for studying they-opioid receptor in humans by means of positron emission tomography.

  The neuropeptide Y (NPY) Y1 receptor (Y1R) selective radioligand (R)-Nα-(2,2-diphenylacetyl)-Nω-[4-(2-[18F]fluoropropanoylamino)butyl]aminocarbonyl-N-(4-hydroxybenzyl)argininamide ([18F]23), derived from the high-affinity Y1R antagonist BIBP3226, was developed for imaging studies of Y1R-positive tumors. Starting from the argininamide core bearing amine-functionalized spacer moieties, a series of fluoropropanoylated

  Numerous radiolabeled peptides have been utilized for in vivo imaging of a variety of cell surface receptors. For applications in PET using [F-18]fluorine, peptides are radiolabeled via a prosthetic group approach. We previously developed solution-phase F-18-"click" radio-labeling and solid-phase radiolabeling using 4-[F-18]fluorobenzoic and 2-[F-18]fluoropropionic acids. Here we compare the three different radiolabeling approaches and report the effects on PET imaging and pharmacokinetics. The prosthetic groups did have an effect; metabolites with significantly different polarities were observed.
