Delta-opioid receptors (DOP receptors) could represent a novel target in the treatment of depressive disorders. To explore this new field of interest, the development of highly selective DOP receptor agonists is essential. UFP-512 [H-Dmt-Tic-NH-CH(CH2-COOH)-Bid], was recently shown to behave in vitro as a selective and potent DOP receptor agonist and to promote antidepressant- and anxiolytic-like effects in vivo (Vergura et al., 2007). Here, we have characterized the pharmacological properties of UFP-512 and established a link between desensitization and tolerance.
