  A Bivalent Ligand (KDN-21) Reveals Spinal δ and κ Opioid Receptors Are Organized as Heterodimers That Give Rise to δ₁ and κ₂ Phenotypes. Selective Targeting of δ−κ Heterodimers

  摘要：

  In view of recent pharmacological studies suggesting the existence of delta-kappa opioid receptor heterodimers/oligomers in the spinal cord, we have synthesized and evaluated (intrathecally in mice) a series of bivalent ligands (KDN series) containing kappa and delta antagonist pharmacophores. Pharmacological and binding data have provided evidence for the bridging of spinal delta-kappa receptor heterodimers by KDN-21 and for their identification as delta(1) and kappa(2). The selectivity profile of KDN-21 and the apparent absence of coupled delta(1)-kappa(2) phenotypes in the brain suggest a new approach for targeting receptors.

  In an effort to develop antagonists for kappa-mu opioid receptor heterodimers, a series of bivalent ligands 3-6 containing kappa- and mu-antagonist pharmacophores were designed and synthesized. Evaluation of the series in HEK-293 cells revealed 4 (KMN-21) to selectively antagonize the activation of kappa-mu heterodimers, suggesting possible bridging of receptors when the bivalent ligand spacer contains 21 atoms.
