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.
