Research Overview

Ghrelin

Ghrelin is the canonical ligand for the growth hormone secretagogue receptor and is used extensively as a reference compound in GH-axis research. Human and animal studies consistently show rapid, dose-dependent GH release after acyl-ghrelin administration.

L-692,429

L-692,429 was important in early GH secretagogue research because it showed that nonpeptide molecules could trigger robust GH release. It remains a classic tool compound for studying receptor-mediated GH pulsatility and appetite signaling.
