  Photoactivatable opiate derivatives as irreversible probes of the .mu.-opioid receptor

  摘要：

  The synthesis of aryldiazonium and arylazido derivatives of carfentanil, etonitazene, and naltrexone and of a triazaspirodecane derivative is described. The chemical stability and the spectral characteristics of these compounds were verified, and their binding affinity constants for the different opioid receptor classes were determined, in the absence of light, from competition experiments. With the exception of the naltrexyl derivatives, which remained nonselective, all compounds tested displayed a pronounced mu-binding selectivity with mu/delta and mu/kappa ratios ranging from 12 to 1000. After irradiation, only the arylazido probes led to an irreversible mu-binding-site inactivation. This inactivation fulfilled the criteria for photoaffinity labeling such as protection against inactivation by other opiate ligands and absence of an effect of scavengers on the extent of the inactivation. Most of the photoactivatable probes formed long-lasting reversible complexes with the opioid binding sites: an efficient dissociation procedure was thus required to discriminate between pseudoirreversible and covalent complexes. The marked differences in labeling efficacy between aryldiazonium salts and their corresponding arylazido derivatives are discussed.

  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.
