1.MECHANISM OF ACTION
The biological effects of α-MSH, Free Acid are primarily mediated through its high-affinity binding to melanocortin receptors (MCRs), a family of G-protein-coupled receptors (GPCRs) distributed across various tissues. In melanocytes, binding to MC1R activates the cAMP/PKA signaling pathway, which phosphorylates the microphthalmia-associated transcription factor (MITF). Phosphorylated MITF upregulates the expression of tyrosinase, tyrosinase-related protein 1 (TRP-1), and TRP-2—key enzymes in melanin synthesis—thereby promoting melanin production and skin pigmentation.
2.PRODUCT INDICATIONS
Skin pigmentation research: Investigation of melanin synthesis mechanisms, development of tools for studying hypopigmentation disorders (e.g., vitiligo) and hyperpigmentation conditions.
Metabolic and weight management research: Exploration of appetite regulation pathways and potential therapeutic targets for obesity, diabetes, and metabolic syndrome.
Anti-inflammatory and immunology research: Development of novel anti-inflammatory agents for treating neuroinflammation, autoimmune diseases, and inflammatory skin conditions.
3.CLINICAL EFFICACY OF PRODUCT
α-MSH, Free Acid is currently in preclinical and early clinical research stages, with promising efficacy demonstrated in multiple in vitro and in vivo models. In animal studies, it has shown significant ability to promote melanin synthesis, providing a potential research basis for treating vitiligo—clinical trials are underway to evaluate its efficacy in repigmenting depigmented skin lesions.
