Abstract
The opioid antagonist activities of two bivalent ligands, BNI and nor-BNI, have been evaluated in smooth muscle preparations and in mice. Both ligands are highly potent and selective as k opioid receptor antagonists, with relatively feeble blocking activity at μ and δ opioid receptors. BNI and nor-BNI represent the first highly selective k opioid receptor antagonists and should be of great utility as molecular probes for identifying the interaction of agonist ligands with k opioid receptors in vitro and in vivo.
