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

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

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

Recently, we have demonstrated that substitution of 1,2,3,4 tetrahyidroisoquinoline-3- carboxylic acid (Tic) in place of Gly2 in dynorphin A-(1-13)-NH2 (DYN) analogue (A) decreased the affinity to the kappa, delta, and micro receptors, and kappa selectivity. The doubly substituted analogue [2',6'-dimethyl-L-tyrosine

Coactivation of spinal alpha(2)-adrenergic receptors (ARs) and opioid receptors produces antinociceptive synergy. Antinociceptive synergy between intrathecally administered alpha(2)AR and opioid agonists is well documented, but the mechanism underlying this synergy remains unclear. The delta-opioid receptor (DOP) and the alpha(2A)ARs are
