英文摘要 | Binding properties and localization of [H-3]ohmefentanyl, a new ligand for mu-opioid receptors, were investigated on normal human brain sections. Binding assays performed at the level of the basal ganglia revealed: (1) a steady-state binding reached after 60 min incubation at room temperature, (2) the presence, in saturation experiments, of an apparent single class of binding sites with a K(d) = 1.68 +/- 0.45 nM and a B(max) = 162 +/- 9 fmol/mg protein, (3) an order of potency to inhibit [H-3]ohmefentanyl binding as follows: ohmefentanyl > [D-Ala2, MePhe4, Gly-ol5]enkephalin (DAGO) > ethylketocyclazocine (EKC) >> Tyr-D-Ser(OtBu)-Gly-Phe-Leu-Thr(OtBu) (BUBU) and U-50,488H. Quantitative autoradiography showed an heterogeneous distribution of [H-3]ohmefentanyl binding sites with the highest densities in amygdala, medial geniculate body, thalamus, and caudate nucleus. Binding characteristics and anatomical distribution also show that [H-3]ohmefentanyl may bind to a small proportion of additional sites called "DAGO-inaccessible [H-3]ohmefentanyl specific binding sites." [H-3]Ohmefentanyl binding to these sites can be partly inhibited by sigma-ligands such as 1,3-di-o-tolylguanidine (DTG) and haloperidol. However, unlabeled DAGO inhibited more than 80% of [H-3]ohmefentanyl specific binding in most of the human brain regions studied, suggesting that the major population of sites labeled by [H-3]ohmefentanyl represented mu-opioid receptors. |
