In experiments to evaluate responses to the activation of cerebral delta-opioid receptors, repeated daily injection of the selective delta-opioid agonist Tyr-D-Ala-Phe-Glu-Val-Val-Gly-NH2 ([D-Ala2]deltorphin II) into rat brain resulted in the development of tolerance, whereas repeated daily injection or continuous infusion of

We propose a common topographical model for the bioactive conformation of deltorphin and dermenkephalin at the delta opioid receptor. In this model a hydrophilic surface from the N- to C-termini is surrounded by lipophilic residues ("hot dog" structure). The important

Nine [D-Ala2]deltorphin II (DL-II:Tyr-D-Ala-Phe-Glu-Val-Val-Gly-NH2) analogs having various aliphatic amino acids at positions 5 and 6 were synthesized to gain more information about the role of hydrophobic Val5,6 residues for the delta-opioid receptor selectivity. Binding assays of analogs replaced by Ala

In the present study, we asked whether multiple intrathecal injections of deltorphin II, a selective delta opioid receptor (DOPR) agonist, induced DOPR tolerance in three behavioral assays. Unilateral inflammation caused by complete Freund's adjuvant (CFA) injection into the rat or
