A series of side-chain constrained tyrosine derivatives, 2‘,6‘-dimethyl-β-methyltyrosines (TMT), has been designed and incorporated into position 1 of the highly selective δ opioid agonists DPDPE (Tyr-d-Pen2-Gly-Phe-d-Pen5-OH) and deltorphin I (DELT I, Tyr-d-Ala-Phe-Asp-Val-Val-Gly-NH2). Molecular mechanics calculations on isolated TMT residues and nuclear magnetic resonance (NMR) studies of the TMT1-containing
Disclosed are a class of µ-opioid receptor agonists and a preparation method therefor and the use thereof in the field of medicine, belonging to the field of medicinal chemistry. The µ-opioid receptor agonists significantly increase the selectivity for a G protein signaling pathway, and not only can exhibit excellent pharmacodynamic effects, but also significantly improve safety.

The invention relates to cyclic peptide agonists that bind to the mu (morphine) opioid receptor and their use in the treatment of acute and/or chronic pain. Embodiments of the invention are directed to cyclic analogs of endomorphin. These peptide analogs exhibit decreased tolerance relative to morphine, increased solubility compared to similar tetrapeptide analogs, while maintaining favorable or improved therapeutic ratios of analgesia to side effects.
