TECHNICAL SPECIFICATIONS

1.MECHANISM OF ACTION

[D-Lys3]-GHRP-6 functions primarily as a selective and competitive antagonist at the Growth Hormone Secretagogue Receptor 1a (GHSR-1a). It binds with high affinity to the ghrelin receptor but does not activate the downstream Gq/11-protein signaling cascade. By occupying the receptor's binding site, it prevents endogenous ghrelin and other agonists (e.g., GHRP-6, GHRP-2) from binding and initiating their biological effects.

2.PRODUCT INDICATIONS

Receptor Pharmacology: Used as a selective tool to block GHSR-1a in in vitroand in vivostudies, confirming the specific involvement of this receptor in observed physiological responses.
Appetite & Metabolism Research: Investigating the role of the ghrelin system in feeding behavior, energy homeostasis, and obesity by antagonizing central GHSR-1a signaling in animal models.
Growth Hormone Axis Studies: Studying the contribution of ghrelin-mediated vs. GHRH-mediated pathways in the pulsatile secretion of GH.
Cancer Research: Exploring the role of GHSR-1a signaling in the proliferation of certain cancer cell lines (e.g., breast, prostate) where ghrelin may act as a mitogen.
Control Experiments: Serving as an essential negative control in experiments using GHSR-1a agonists to verify that observed effects are receptor-specific.
Drug Discovery: Screening and characterizing new GHSR-1a ligands by using it as a reference antagonist in competition binding assays.

3.CLINICAL EFFICACY OF PRODUCT

Preclinical Research Efficacy: It is widely recognized as a potent and selective GHSR-1a antagonist in animal and cellular models. Studies demonstrate its effectiveness in suppressing ghrelin-induced GH release and food intake.
Therapeutic Target Validation: Research using this antagonist has been instrumental in validating GHSR-1a as a therapeutic target for conditions like obesity, cachexia, and certain cancers. It helps establish cause-and-effect relationships for ghrelin's actions.
Clinical Translation Gap: This specific peptide is not a drug candidate. However, the knowledge gained from its use supports the development of small-molecule GHSR-1a antagonists currently under investigation in clinical trials for obesity and metabolic disorders.
Status: No human clinical trials have been conducted with [D-Lys3]-GHRP-6. Its value is entirely in generating robust preclinical data to guide future therapeutic development.
