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

Frequently Asked Questions

What is Receptor Agonist?
