Receptor Agonist
Receptor Agonist — A compound that binds to a receptor and activates it, producing a biological response similar to the natural ligand.
What Is a Receptor Agonist?
A receptor agonist is a ligand that binds to and activates a receptor, triggering a signaling cascade. Full agonists produce maximum response; partial agonists produce submaximal response even at saturating concentration. Most peptide hormones are natural agonists of their cognate receptors.
Peptide Agonist Examples
- Ipamorelin: Full GHS-R1a agonist. Selective GH release
- Semaglutide: GLP-1R agonist with lipidation for weekly dosing
- Oxytocin: Full OTR agonist. Uterine contraction and social bonding
