1.MECHANISM OF ACTION
The mechanism of action involves selective binding to and activation of melanocortin receptor 3 (MC3R), a G-protein coupled receptor predominantly expressed in the hypothalamus and peripheral tissues. Receptor engagement triggers intracellular cAMP accumulation through Gαs protein coupling, leading to downstream signaling cascades that modulate energy expenditure, appetite regulation, and metabolic processes. The N-terminal acetylation and Nle³ substitution enhance peptide stability against enzymatic degradation and improve receptor binding affinity, resulting in prolonged biological activity compared to the native γ2-MSH. This selective MC3R agonism makes it a specific tool for dissecting the physiological roles of this receptor subtype in metabolic homeostasis.
2.PRODUCT INDICATIONS
This γ2-MSH analog is indicated for research use only in preclinical studies investigating melanocortin receptor biology, energy metabolism, obesity and metabolic syndrome, and cardiovascular regulation. It serves as a selective MC3R agonist in receptor binding assays, functional assays measuring cAMP production, and animal models of metabolic disorders. The product is used to study the role of MC3R in appetite control, energy balance, and glucose homeostasis, as well as in structure-activity relationship studies for developing novel therapeutic compounds targeting melanocortin pathways. It is not intended for diagnostic, therapeutic, or clinical applications in humans or animals, and should be handled by trained research personnel in appropriate laboratory settings.
3.CLINICAL EFFICACY OF PRODUCT
As a research reagent, Ac-[Lys⁰,Nle³]-γ2-MSH amide does not have established clinical efficacy for therapeutic use in human patients. While this peptide analog and related compounds have been studied in preclinical models to understand MC3 receptor physiology and its role in metabolic regulation, the product itself has not undergone clinical development or received regulatory approval for any medical indication. Research using this peptide has contributed to the understanding of melanocortin signaling in energy homeostasis and the identification of potential therapeutic targets for metabolic diseases, but the product remains an investigational research tool without proven clinical efficacy or safety profile for human use.
