    We thank J. Such analysis was made in SDS micelle solution. Pan, Y. Yet, the good correlation that we found in this study is important, because it suggests that there is no dissociation between ligand-induced coupling to the G protein and ligand-promoted changes in the nucleotide-exchange properties of the G protein, within the studied ligands.

Science — Although this is the first study in which a systematic assessment of the efficacy of NOP agonists for arrestin was made, previous results based on NOP receptor internalization show that agonists active in promoting internalization of the NOP receptor [ 5960 ] are among those that in this study display a robust effect on arrestin coupling.

These pharmacophores were linked with spacers of different length covering the range that has been previously and successfully employed for the generation of dimeric ligands for opioid receptors.

    For the synthesis of compounds 91113 and 15cysteamine 2-chlorotrityl resin has been employed as solid support. Very similar results were obtained using as NOP receptor pharmacophore the non-peptide ligand Ro compounds 19— As far as opioid peptide ligands are concerned, delta receptor homodimeric ligands generated using the enkephalin tetrapeptide Tyr-Gly-Gly-Phe and the opioid related sequence Tyr-D-Ala-Gly showed an increased delta receptor potency and selectivity compared with the corresponding monomers 21 The alkylation in position 3 of the 1,3,8-triaza[4.

    Biochemical and Biophysical Research Communications. As far as ligand synthesis is concerned, homodimeric ligands with peptide nature, compounds 1—91113were obtained by linking via disulphide bridge two monomers in which a thiol moiety has been added at the C-terminal.

Hiller, C. Thus, it is conceivable that the very slow dissociation rate of these ligands and the consequent effect on the agonist ability to reach a steady-state level of receptor occupancy are responsible for the phenomenon.

    We also measured the inhibitory potency for arrestin coupling of the other antagonists, such as J, SB, C, J, and, naloxone.

    In agreement with such a conclusion, little evidence for NOP receptor constitutive activity has been described so far, at least under physiological conditions. However, one interesting observation is that two of such antagonists, SB and C, displayed a pattern of agonist inhibition suggesting insurmountable behavior under some assay conditions i. Data block sizes were addresses in t 2 and equidistant t 1 values.

    These experiments were then repeated by increasing to 15 min the time between agonist injection and the measure of BRET ratio. We found, however, that a 3-fold increase in incubation time was sufficient to restore an essentially competitive pattern of antagonism in these compounds, while other antagonists with lower potency, such as UFP or J, did not show similar time-dependent changes.
