Literature

Research context

MK-677 is an orally bioavailable mimetic of the GH-releasing peptides, characterised in the literature as a GHS-R1a agonist with a long plasma half-life. Published work covers receptor binding and internalisation, pulsatile GH-axis dynamics in animal models, and its role as the reference non-peptide secretagogue in ghrelin-receptor pharmacology. Supplied as the mesylate salt.

Documented research areas

  • GHS-R1a (ghrelin receptor) agonism
