Melanotan-1 Research Peptide | High-Purity Synthesis for Laboratory Analysis

Overview: Buy Melanotan-1 for Advanced Peptide Research

Melanotan-1 (also known as Afamelanotide or [Nle4, D-Phe7]-α-MSH) is a synthetic analog of human alpha-melanocyte-stimulating hormone (α-MSH). Designed to mimic the physiological action of endogenous melanocortin peptides, Melanotan-1 interacts primarily with melanocortin receptors (predominantly MC1R) to induce melanogenesis in research models.

When sourcing laboratory-grade reagents in the United States, chemical purity, structural integrity, and batch consistency are paramount.

What Is Melanotan-1?

Melanotan-1 is a linear 13-amino-acid peptide engineered to act as a potent, non-selective agonist at melanocortin receptors MC1R, MC3R, MC4R, and MC5R. Unlike endogenous α-MSH, which exhibits a brief half-life due to rapid enzymatic degradation, Melanotan-1 incorporates structural modifications—specifically the substitution of Norleucine at position 4 and D-Phenylalanine at position 7—to enhance enzymatic resistance and biological stability.

Researchers investigate Melanotan-1 for its receptor-binding kinetics, role in stimulating melanin production, photoprotective mechanisms, and potential interactions within cellular signaling pathways.

Key Areas of Research Exploration

1. Melanogenesis & MC1R Activation

The primary mechanism of action for Melanotan-1 centers on its selective binding to Melanocortin-1 Receptors (MC1R) located on the surface of melanocytes. Receptor activation initiates intracellular cyclic adenosine monophosphate (cAMP) production, activating protein kinase A (PKA) and upregulating microphthalmia-associated transcription factor (MITF). This chain of signaling drives enzymatic expression of tyrosinase, increasing synthesized eumelanin in experimental models.

2. Photoprotective Potential

Eumelanin serves as a natural photoprotectant by dissipating ultraviolet (UV) radiation as heat and scavenging reactive oxygen species (ROS). Studies evaluate Melanotan-1 to understand how induced melanogenesis offers photoprotection against UV-induced DNA damage, erythema, and oxidative stress in epidermal tissue models.

3. Receptor Subtype Selectivity

Unlike its cyclic derivative Melanotan-2, Melanotan-1 displays distinct selectivity profiles among melanocortin receptor subtypes. Research frequently compares the binding profiles, potency, and side-effect parameters of linear α-MSH analogs versus cyclic structures to map receptor crosstalk across neurochemical and peripheral signaling axes.
