Melanotan II (MT-II) is a synthetic peptide that has captured the attention of researchers and the cosmetic industry alike, primarily for its potent effects on skin pigmentation and tanning. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in the precise synthesis of complex chemical compounds, including peptides like Melanotan II, providing essential materials for cutting-edge research and development.

Chemically, Melanotan II is a cyclic peptide analogue of the alpha-melanocyte-stimulating hormone (α-MSH). Its sequence is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, distinguishing it from its predecessor, Melanotan I. The synthesis of Melanotan II involves sophisticated peptide chemistry, ensuring high purity and specific structural integrity, which are critical for reliable research outcomes. The precise chemical formulation allows it to effectively interact with melanocortin receptors throughout the body.

The primary mechanism of action for Melanotan II is its agonistic activity on melanocortin receptors, notably MC1R, MC3R, MC4R, and MC5R. Activation of MC1R in melanocytes stimulates the production of melanin, the pigment responsible for skin tanning. This makes Melanotan II a powerful agent for inducing skin darkening. Beyond pigmentation, its interaction with MC4R has been linked to effects on appetite and sexual function, highlighting its broader physiological influence.

The research applications for Melanotan II are diverse. Its most recognized use is in cosmetic dermatology for achieving a tan, but it also serves as a valuable tool in endocrinology, neuroscience, and reproductive health research due to its effects on various melanocortin receptor pathways. Understanding these complex interactions is vital for advancing scientific knowledge in these fields.

It is crucial for researchers to be aware of the regulatory status of Melanotan II. In many regions, it is sold as an unregulated substance, meaning its production and distribution are not subject to the same stringent oversight as approved pharmaceuticals. This underscores the importance of sourcing Melanotan II from reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD., who prioritize quality control and provide comprehensive product documentation, such as Certificates of Analysis (CoA). Such documentation assures the purity and identity of the peptide, which is non-negotiable for reproducible and valid research findings. By providing high-quality Melanotan II, we aim to support the scientific community in their pursuit of groundbreaking discoveries.
