What DPhe-DPhe-DLeu-DOrn-NHMorpholine is studied for

  • Opioid-receptor binding and selectivity profiling
  • β-arrestin recruitment and biased-agonism studies
  • Analgesic mechanism research
  • Tolerance and dependence models

Mechanism of action

DPhe-DPhe-DLeu-DOrn-NHMorpholine sits within the Opioid research class (CPC reference OPIO-009). Opioid peptides bind μ, δ, and κ receptors — Gi/o-coupled GPCRs that inhibit adenylate cyclase, activate GIRK channels, and modulate calcium currents to produce analgesia, tolerance, and reward-circuit effects. Investigators typically incorporate DPhe-DPhe-DLeu-DOrn-NHMorpholine as a reference standard, tool ligand, or substrate in the assay contexts listed above. GTPγS binding, cAMP HTRF, and β-arrestin PathHunter assays.
