From the Potent and Selective μ Opioid Receptor Agonist H-Dmt-d-Arg-Phe-Lys-NH2 to the Potent δ Antagonist H-Dmt-Tic-Phe-Lys(Z)-OH
摘要:
H-Dmt-D-Arg-Phe-Lys-NH2 ([Dmt(1)]DALDA) binds with high affinity and selectivity to the mu opioid receptor and is a potent and long-acting analgesic. Substitution of D-Arg in position 2 with Tic and masking of the lysine amine side chain by Z protection and of the C-terminal carboxylic function instead of the amide function transform a potent and selective mu agonist into a potent and selective delta antagonist H-Dmt-Tic-Phe-Lys(Z)-OH. Such a delta antagonist could be used as a pharmacological tool.

Identification and pharmacological characterization of two new selective delta-opioid receptorantagonists, derivedfrom the Dmt-Tic pharmacophore, of potential utility in positron emission tomography (PET) imaging are described. On the basis of its high delta selectivity, H-Dmt-Tic--Lys(Z)-OH (reference compound 1) is a useful starting point for the synthesis of (18)F-labeled compounds prepared by the
