A series of cyclic, disulfide- or dithioether-containing tetrapeptides based on previously reported potent mu- and delta-selective analogs has been explored with the aim of improving their poor affinity to the kappa-opioid receptor.

Indeed, peptide 8, Tyr-C [D-Cys-Phe-Phe-Cys]-NH2-cyclized via a methylene dithioether, shows picomolar binding affinity for MOR ( = 16 pm) with more than 100-fold selectivity for MOR vs.
