GHRH Receptor Activation
GHRH-R Agonist
Four substitutions — at positions 2, 8, 15 and 27 — each block a site where enzymes would cleave native GHRH(1-29). The receptor interaction is unchanged; only the molecule's survival time is.
- Selective for the GHRH receptor
- Position-2 substitution blocks DPP-IV cleavage
- Binds pituitary somatotrophs at high affinity
