Mono iodinated analogues of biphalin [(Tyr-D-Ala-Gly-Phe-NH-)2], both nonradioactive [I-Tyr1]biphalin and radioactive [125I-Tyr1]biphalin have been synthesized. The radioligand binding profiles of these compounds for two types of tissues, rat brain membranes, and NG108-15 cell membranes were identical to the parent biphalin.

Opioid binding sites in the bovine pineal were characterized using the highly selective delta opioid agonist 3H-[D-Pen2,pCl-Phe4,D-Pen5] enkephalin (DPDP(C1)E). Pineal membranes possess a single class of high affinity binding sites for this delta ligand (Kd = 0.26 nM; Bmax =

Certain enkephalin analogues, including those which contain the conformationally restricted amino acid E-(2R,3S)-cyclopropylphenylalanine [2R,3S)-delta E Phe), have been shown to have high affinity for brain delta opioid receptors but are much less active in mouse vas deferens bioassays. To investigate

To improve pharmacological characteristics of the delta-selective, cyclic peptide [D-Pen2, D-Pen5]enkephalin (DPDPE), modification by halogenation at the Phe4 residue was undertaken. The present study was to determine the extent [3H]DPDPE, [3H][p-Cl-Phe4]DPDPE and [p-125IPhe4]DPDPE crosses the blood-brain barrier, elicits analgesia and
