1.MECHANISM OF ACTION

β-MSH, Human exerts its biological effects primarily by binding to specific melanocortin receptors (MCRs) in various tissues and activating downstream signaling pathways. For skin pigmentation regulation, it binds to MC1R on melanocytes, activating the G-protein-coupled signaling pathway to increase intracellular cyclic adenosine monophosphate (cAMP) levels. Elevated cAMP further activates protein kinase A (PKA), which phosphorylates the microphthalmia-associated transcription factor (MITF), upregulating the expression of tyrosinase and other melanin-synthesis-related genes, thereby promoting melanin production and secretion.

2.PRODUCT INDICATIONS

Skin pigmentation research: Exploration of melanin synthesis mechanisms and the development of whitening or tanning-related research tools.

Metabolic disorder research: Investigation of appetite regulation, energy balance, and potential targets for obesity and metabolic syndrome treatment.

Inflammatory response research: Development of anti-inflammatory drugs and immunomodulators based on its anti-inflammatory properties.

3.CLINICAL EFFICACY OF PRODUCT

β-MSH, Human is in the preclinical research stage, and its potential clinical efficacy has been verified in multiple in vitro and in vivo studies. In animal experiments, it has been shown to significantly inhibit food and water intake in chicks and rats, demonstrating its potential in regulating energy metabolism and weight control. In anti-inflammatory research, it effectively suppresses LPS-induced NF-κB nuclear translocation and NO overproduction in brain tissues, indicating promising applications in treating neuroinflammatory diseases.
