01 /What it is
Endomorphin-1 is an endogenous tetrapeptide (Tyr-Pro-Trp-Phe-NH2) discovered in the late 1990s. It is a reference ligand in selective mu opioid receptor research.
02 /How it works
In research models, Endomorphin-1 is studied as a highly selective agonist at the mu opioid receptor. Its profile is investigated in receptor selectivity research and in central nervous system signaling research.
03 /What researchers explore it for
Researchers have explored Endomorphin-1 in mu opioid receptor research, in central signaling research, and in receptor selectivity research alongside Endomorphin-2.
04 /Safety and interactions
Research interactions of note include receptor level overlap with other endogenous opioid peptides. Endomorphin-1 is for laboratory research use only and is not for human consumption. Not medical advice. Not intended to diagnose, treat, cure, or prevent any disease.
05 /Research notes
Peptide family: endogenous opioid tetrapeptides. Frequently compared with Endomorphin-2. The Apothify library lists Endomorphin-1 for encyclopedia coverage only.
