The 14-O-benzylnaltrexones 3-6 were prepared from naltrexone (2) in several steps. The novel compounds were biologically evaluated in radioligand binding and in [35S]GTPγS functional assays in comparison to the reference compound naltrexone. In the binding assay, compounds 3-6 exhibited preference for κ opioid receptors, while the parent compound naltrexone shows preference for μ receptors. In the functional assay, μ antagonist potency of compounds 3-6 was in the range of naltrexone, while K antagonist potency was considerably higher for most novel compounds in comparison to naltrexone.
