About MK-677 (Ibutamoren)
MK-677 is not a peptide. It is a spiroindoline small molecule developed by Merck in the 1990s to reproduce, in a non-peptide scaffold, the activity of the growth hormone-releasing peptides at the ghrelin receptor (GHS-R1a). It is usually handled as its mesylate salt.
Because it resists the peptidases that degrade peptide secretagogues, it has a long duration of action and is commonly used as a small-molecule reference agonist for the ghrelin receptor.
Research context
MK-677 is used in research on ghrelin-receptor signaling and growth hormone and IGF-1 regulation, and in comparisons between peptide and non-peptide ghrelin-receptor agonists such as ipamorelin and GHRP-2.
