2,6-Dimethyltyrosine analogues of a stereodiversified ligand library: highly potent, selective, non-peptidic mu opioid receptor agonists.

We recently reported the use of an exhaustively stereodiversified library based on endomorphin-2 (1) to discover mu opioid receptor ( MOR) ligands of type 2-4. Here, we report the synthesis and evaluation of 2,6-dimethyltyrosine analogues 5-10. These analogues showed improved affinity for MOR relative to 2-4. In the cases of 5 and 6, we synthesized and evaluated five stereoisomers of each, thereby discovering stereoisomers with unexpected potency, selectivity, and efficacy. These results illustrate the utility of acyclic, stereodiverse libraries.[1]
