pharmacophore Dmt-Tic were synthesized, and their binding affinity and functional bioactivity at the μ, δ and κopioidreceptors determined. Bifunctional ligands containing or not a spacer of β-alanine between the two pharmacophores lose the μ agonism deriving from morphine becoming partial μ agonists 4 or μantagonists 5. Partial κ agonism is evidenced only for compound 4. Finally, both compounds showed
