Contesto di ricerca
Profilo di ricerca Hexarelin
Hexarelin is a synthetic hexapeptide growth hormone secretagogue studied at the ghrelin receptor. Research includes GH-release response, receptor potency, endocrine markers, desensitization, and experimental cardiac or metabolic signaling observations. It is often compared with GHRP-2, GHRP-6, and ipamorelin to examine differences in potency and selectivity, while GHRH analogs such as sermorelin and CJC-1295 provide a separate receptor pathway for comparison. Hexarelin is most appropriate when a study specifically needs this GHS-R ligand rather than a general GH-axis material. Much of the broader mechanistic evidence is preclinical or early-stage and should remain tied to its original model.
Molecular class
Six-residue GH secretagogue
Sequence / composition
His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2; a modified hexapeptide with non-native stereochemistry.
Research design note
Sequence modifications are central to its potency and mean it should not be treated as a native ghrelin fragment.
Meccanismo proposto
A potent synthetic GHS-R1a agonist that stimulates GH release through pituitary and hypothalamic pathways. Additional cardiac and cytoprotective mechanisms have been proposed in preclinical studies, some potentially independent of GH.
Effetti riportati negli studi
- Human pharmacology studies reported strong acute GH release and endocrine responses after hexarelin exposure.
- Animal and cell studies reported changes in cardiac function, survival signaling, fibrosis, and tissue-injury markers.
- Repeated exposure can cause desensitization, and cardiac findings remain largely preclinical and mechanism dependent.
Endpoint di ricerca comuni
GHS-R potency, GH, ACTH, cortisol, prolactin, receptor desensitization, cardiac contractility, fibrosis, apoptosis, inflammatory markers, and pharmacokinetics.
Evidenze e limiti
Human evidence primarily addresses acute endocrine pharmacology; proposed cardiac effects are largely preclinical and not established as human outcomes.
