Melanotan II (MT-II) is a synthetic peptide that has carved a unique niche in scientific research due to its distinctive effects on skin pigmentation and its role as a melanocortin receptor agonist. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of research peptides, offering high-purity Melanotan II to support a wide array of scientific investigations. This guide aims to provide a comprehensive overview of MT-II, covering its history, mechanism of action, and diverse research applications, relevant to cosmetic peptides research and advanced peptide therapeutics. Originally developed in the 1990s, Melanotan II emerged from research efforts aimed at creating sunless tanning agents. It functions as a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). Its mechanism of action involves binding to melanocortin receptors (MCRs), including MC1R, MC3R, MC4R, and MC5R. Activation of MC1R on melanocytes is primarily responsible for stimulating melanin production, leading to the characteristic skin darkening or tanning effect. This has made it a focal point in research concerning skin health and pigmentation. Beyond its tanning properties, research has indicated that Melanotan II's interaction with other MCRs, particularly MC4R, may influence various physiological processes, including libido, appetite, and potentially even thermoregulation and neuroprotection. This broad spectrum of effects makes MT-II a valuable compound for researchers studying hormonal analogues and their complex biological roles. The potential for libido enhancement and appetite modulation are significant areas of ongoing investigation.
