What is the Origin of Selective Growth Hormone Secretagogues?

The term is a product of peptide chemistry and clinical endocrinology, emerging from the search for agents that could safely mimic the beneficial effects of growth hormone. The 'selective' modifier differentiates these compounds from broader hypothalamic-releasing hormones that might trigger multiple pituitary axes. The development was driven by the goal of restoring youthful GH pulsatility, which declines naturally with age.

What is the Mechanism of Selective Growth Hormone Secretagogues?

Selective Growth Hormone Secretagogues bind with high affinity to the GHSR-1a receptor on somatotroph cells in the pituitary. This binding activates a G-protein-coupled signaling pathway, leading to an influx of calcium ions into the cell. The resultant increase in intracellular calcium is the direct trigger for the exocytosis and release of stored growth hormone into the systemic circulation, mimicking the natural pulsatile rhythm of GH secretion.

Selective Growth Hormone Secretagogues

Meaning

A class of pharmaceutical agents that specifically and selectively stimulate the release of endogenous growth hormone (GH) from the anterior pituitary gland without significantly affecting the secretion of other pituitary hormones. These compounds act as agonists at the Growth Hormone Secretagogue (GHS) receptor, providing a pulsatile, physiological boost to GH levels. The ‘selective’ nature of these secretagogues offers a nuanced clinical tool for addressing age-related growth hormone decline while minimizing potential off-target endocrine effects.
