Overview: GHRP-2, also known as pralmorelin, is a synthetic hexapeptide that functions as a potent growth hormone secretagogue (GHS). It stimulates the release of growth hormone (GH) by acting on the ghrelin receptor (GHS-R1a) and has been studied for its potential in treating GH deficiencies, cachexia, and age-related hormonal decline. Beyond GH stimulation, GHRP-2 exhibits cytoprotective, cardioprotective, and anti-inflammatory properties.
GHRP-2 exerts its effects through multiple pathways:
GHS-R1a Activation: Binds to the ghrelin receptor, leading to increased GH release from the anterior pituitary.
CD36 Interaction: Engages with the CD36 receptor, activating PI3K/AKT1 signaling pathways that promote cell survival and reduce apoptosis.
Modulation of Hormonal Axes: Influences the hypothalamic-pituitary-adrenal (HPA) axis, potentially affecting cortisol and ACTH levels.
Appetite Stimulation: Mimics ghrelin's orexigenic effects, increasing food intake and body weight in various model
Preclinical and Clinical Studies:
Growth Hormone Secretion: Demonstrated significant GH release in both animal models and human subjects, with potential applications in diagnosing GH deficiencies.
Cardioprotection: Shown to reduce myocardial infarct size and improve cardiac function post-ischemia by mitigating oxidative stress and apoptosis.
Cytoprotection: Offers protective effects in hepatic, neuronal, and gastrointestinal tissues against various insults.
Metabolic Effects: Enhances lean body mass, reduces fat accumulation, and improves lipid profiles in preclinical studies.
Appetite and Weight Gain: Increases food intake and body weight, suggesting potential in treating cachexia and anorexia.
