Biochem/physiol Actions

Ghrelin/growth hormone secretagogue receptor (GHSR) agonist; Growth hormone-releasing peptide
Pralmorelin, also known as Growth hormone-releasing peptide 2 or GHRP-2, is an orally-active, synthetic peptide analogue of met-enkephalin that acts as a ghrelin/growth hormone secretagogue receptor (GHSR) agonist to selectively stimulate the ghrelin receptor and cause growth hormone release. Pralmorelin (GHRP-2) has been used clinically for the assessment of growth hormone deficiency (GHD), It has also been shown to have anti-inflammatory activity.

Cyclooxygenase-2 (COX-2) and interleukin-8 (IL-8) are two important inflammatory mediators in ovulation. Ghrelin may modulate inflammatory signaling via growth hormone secretagogue receptors. We investigated the role of ghrelin in KGN human ovarian granulosa cells using protein kinase C (PKC) activator

The aim of this study was to evaluate the ability of the growth hormone-releasing peptide-2 (GHRP-2) test to clinically diagnose hypothalamo-pituitary-adrenal (HPA) axis failure. We performed an insulin tolerance test (ITT), CRH stimulation test, and GHRP-2 test on 47 patients
