DTrp-Gamma MSH

DTrp-γ-MSH is a synthetic peptide analog of γ-melanocyte stimulating hormone (γ-MSH) featuring D-tryptophan (D-Trp) substitution and typically containing a disulfide bridge structure to enhance metabolic stability and receptor selectivity. This research-grade reagent is designed as a selective agonist for melanocortin receptors, with particular affinity for MC3 and MC5 receptor subtypes involved in energy homeostasis and metabolic regulation. The product is provided as a lyophilized powder with high purity and is intended for preclinical research applications in metabolic disorders, obesity studies, and appetite regulation research, serving as a valuable pharmacological tool for investigating melanocortin receptor signaling pathways in both academic and pharmaceutical settings.

1.MECHANISM OF ACTION

The mechanism of action involves selective binding to and activation of melanocortin receptors, primarily MC3R and MC5R, which are G-protein coupled receptors expressed in various tissues including the hypothalamus and peripheral organs. 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 D-Trp substitution enhances peptide stability against enzymatic degradation and improves receptor binding affinity, while the disulfide bridge (if present) stabilizes the peptide's secondary structure, collectively resulting in prolonged biological activity and improved selectivity compared to the native γ-MSH.

2.PRODUCT INDICATIONS

This DTrp-γ-MSH analog is indicated for research use only in preclinical studies investigating melanocortin receptor biology, energy metabolism, obesity and metabolic syndrome, and appetite regulation mechanisms. It serves as a selective melanocortin receptor agonist in receptor binding assays, functional assays measuring cAMP production or calcium mobilization, and animal models of metabolic disorders. The product is used to study the role of MC3R and MC5R in energy balance, glucose homeostasis, and cardiovascular regulation, 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.

3.CLINICAL EFFICACY OF PRODUCT

As a research reagent, DTrp-γ-MSH 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 melanocortin 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.
