Nonapeptide-1 (200mg) Research Peptide – High-Purity Supply from Core Peptide USA

Nonapeptide-1 (200mg) is a synthetic research peptide composed of nine amino acids that has attracted significant scientific interest for its potential role in melanogenesis inhibition. First developed in the 1990s, Nonapeptide-1 has been studied for its interaction with the melanocortin-1 receptor (MC1R), a key receptor involved in melanin production and pigmentation pathways.

At Core Peptide (https://corepeptide.us), we provide Nonapeptide-1 (200mg) exclusively for laboratory and research purposes, supplying researchers across the United States with high-quality, rigorously tested peptides designed to support advanced scientific investigation.

What Is Nonapeptide-1?

Nonapeptide-1 is a nine-amino-acid peptide originally identified during large-scale screening of melanocortin-1 receptor antagonists. Researchers were exploring compounds capable of inhibiting MC1R signaling, a pathway closely associated with melanin synthesis in melanocytes.

Melanin is the primary pigment responsible for coloration of skin, hair, and eyes in mammals. Overproduction or uneven distribution of melanin has been linked to conditions such as hyperpigmentation and melasma. Because of this, Nonapeptide-1 (200mg) has become a focus of research in pigmentation-related studies.

Chemical Makeup of Nonapeptide-1 (200mg)

• Molecular Formula: C₆₁H₈₇N₁₅O₉S

• Molecular Weight: 1206.5 g/mol

• Peptide Length: 9 amino acids

The specific amino acid sequence of Nonapeptide-1 has been shown in studies to be critical for its antagonistic interaction with MC1R, particularly residues such as D-Trp and Phe, which enhance receptor binding affinity.

Mechanism of Action: MC1R Antagonism

Research suggests that Nonapeptide-1 (200mg) may inhibit melanin synthesis by interfering with the melanocortin-1 receptor signaling pathway. MC1R is activated by alpha-melanocyte-stimulating hormone (α-MSH), which increases tyrosinase activity—an essential enzyme in melanin production.

According to published findings in the Journal of Biological Chemistry, Nonapeptide-1 demonstrated strong antagonistic properties with an IC₅₀ value of approximately 11 ± 7 nM, indicating high receptor affinity. By blocking MC1R activation, researchers theorize that Nonapeptide-1 may reduce downstream melanin synthesis without altering α-MSH levels.

Nonapeptide-1 and Pigmentation Research

In vitro and laboratory studies investigating Nonapeptide-1 (200mg) have examined its effects on melanocytes and keratinocyte cell lines. In controlled experiments, cells exposed to Nonapeptide-1 showed reduced tyrosinase activity and downregulation of melanogenesis-related proteins such as TRP-1, TRP-2, and MITF.

Additional studies hypothesize that Nonapeptide-1 may contribute to a visible reduction in melanin production over time. A small double-blinded randomized clinical pilot study reported improvements in melasma severity and mean melanin index when Nonapeptide-1 was incorporated into research formulations.

Broader Research Potential of Nonapeptide-1

Beyond pigmentation studies, melanocortin-1 receptors are expressed in other tissues, including nerve cells and immune cells. This has opened new research pathways for Nonapeptide-1 (200mg) in areas such as nociception and inflammatory response.

Animal studies involving MC1R antagonists have suggested altered inflammatory pain responses, particularly in female subjects. Additionally, research into melanoma cell lines has shown that inhibiting MC1R signaling may slow tumor cell growth and reduce cellular heterogeneity. While Nonapeptide-1 itself has not yet been directly studied in melanoma models, these findings highlight promising future research directions.
