  A Bivalent Ligand (KDAN-18) Containing δ-Antagonist and κ-Agonist Pharmacophores Bridges δ₂ and κ₁ Opioid Receptor Phenotypes

  摘要：

  To characterize delta- and kappa-opioid receptor phenotypes, bivalent ligands (KDAN series) containing delta-antagonist (naltrindole) and kappa(1)-agonist (ICI-199,441) pharmacophores were synthesized and evaluated by the intrathecal route using the mouse tail-flick assay and binding studies. The data have suggested that KDAN-18 (2) bridges phenotypic delta(2)- and kappa(1)-receptors. A conceptual model is presented to explain the organizational differences between the opioid receptors that give rise to the phenotypes (delta(1), delta(2), kappa(1), kappa(2)).

• A κ Opioid Pharmacophore Becomes a Spinally Selective κ-δ Agonist When Modified with a Basic Extender Arm

  We have explored the concept of a molecular extender arm attached to a kappa opioid agonist pharmacophore 3 (ICI-199,441) in an effort to potentially interact, with a complementary group on a neighboring opioid receptor. The containing a terminal amine group was lengthened incrementally from 11 1 up to 18 atoms. Increasing the number-of atoms in the arm produced virtually no change in the mouse intracerebroventricular (i.c.v.) antinociceptive potency In contrast, the intrathecal (i.t.) potency of 6 (KDA-16) with a 16 atom arm was dramatically increased, as reflected by its antinociceptive i.c.v./i.t. ED50 ratio of similar to 130. Further lengthening led to a decreased ED50 ratio. In vivo selective antagonist studies of KDA-16 revealed that kappa and delta opioid receptors were responsible for the greatly enhanced it potency Calcium release experiments in HEK-293 cells suggested that KDA-16 selectively activate kappa-delta heteromers. These data are consistent with the reported possible presence of heteromeric kappa-delta opioid receptors in mouse spinal cord but not in the brain. The use of a molecular extender arm may be useful for developing spinally selective analgesics.
