β‑MSH, porcine CAS NO.19941-13-0

β‑MSH, porcine (CAS NO.: 19941-13-0) is a bioactive 18-amino-acid peptide belonging to the melanocortin family, naturally expressed in the pituitary gland of porcine species. With a molecular formula of C₉₈H₁₃₈N₂₆O₂₉S and a molecular weight of 2176.4 g/mol. As a potent agonist of melanocortin receptors (MC1R, MC3R, MC4R, MC5R), it exhibits diverse physiological functions, including stimulating melanin synthesis, modulating appetite and energy metabolism, and exerting anti-inflammatory effects. Our β‑MSH, porcine is manufactured under strict quality control, ensuring ≥95% purity (RP-HPLC), low endotoxin levels, and stable biological activity, making it an ideal tool for scientific research, pharmaceutical R&D, and biochemical experimentation.

1.MECHANISM OF ACTION

The biological effects of β‑MSH, porcine are primarily mediated through its high-affinity binding to melanocortin receptors (MCRs), a family of G-protein-coupled receptors 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 and other melanin-synthesis-related enzymes, thereby promoting melanin production and skin pigmentation.

2.PRODUCT INDICATIONS

Skin pigmentation research: Investigation of melanin synthesis mechanisms, development of tools for studying hypopigmentation and hyperpigmentation disorders.

Metabolic research: Exploration of appetite regulation pathways and potential therapeutic targets for obesity, diabetes, and metabolic syndrome.

Anti-inflammatory research: Development of novel anti-inflammatory agents for treating neuroinflammation, autoimmune diseases, and inflammatory skin conditions.

3.CLINICAL EFFICACY OF PRODUCT

β‑MSH, porcine is currently in preclinical research stages, with promising efficacy demonstrated in multiple in vitro and in vivo models. In animal studies, it has shown significant ability to stimulate melanin synthesis in porcine and rodent melanocytes, providing a potential research basis for treating hypopigmentation disorders such as vitiligo.
