Melanotan 1 Peptide Canada Research Summary

Melanotan I (afamelanotide, NDP-alpha-MSH) is a synthetic linear analog of alpha-melanocyte stimulating hormone containing two key modifications: norleucine substitution at position 4 (replacing methionine) and D-phenylalanine substitution at position 7. These modifications were developed by the University of Arizona research group to create a superpotent alpha-MSH analog with enhanced metabolic stability. The melanotan 1 peptide Canada product retains the full 13-amino acid linear structure of alpha-MSH unlike the truncated cyclic structure of Melanotan II.

Melanotan I demonstrates preferential selectivity for the MC1R melanocortin receptor compared to the non-selective profile of Melanotan II. This MC1R selectivity makes it a more targeted research tool for melanocyte biology studies, though it retains measurable activity at other melanocortin receptor subtypes in binding assays.

Mechanism of Action Research

MT-I acts primarily through the MC1R receptor expressed on melanocytes. Receptor activation triggers adenylyl cyclase signaling, elevating intracellular cAMP, which activates protein kinase A (PKA) and subsequently the MITF (melanocyte-inducing transcription factor) pathway. This cascade leads to upregulation of tyrosinase and other enzymes involved in melanin biosynthesis in cell culture models.

The norleucine-4 modification eliminates the methionine residue susceptible to oxidation, while the D-phenylalanine-7 substitution enhances receptor binding affinity by constraining the peptide backbone in a conformation that favors MC1R interaction. Published binding studies have demonstrated 10-100 fold increased potency compared to native alpha-MSH at the MC1R.

Research comparing MT-I to MT-II has examined selectivity ratios across melanocortin receptor subtypes, providing insights into structure-activity relationships within the melanocortin peptide family. These comparative studies have been foundational in melanocortin receptor pharmacology research.

Preclinical Study Summary

MT-I has been studied in melanocyte biology, photoprotection research, and erythropoietic protoporphyria models. Published research has examined its effects on melanogenesis, UV-induced DNA damage, and melanocyte proliferation in various experimental systems.

All findings are from preclinical research. No therapeutic claims are made.

Frequently Asked Questions

What is the CAS number for Melanotan 1?

The CAS registry number for Melanotan 1 (Afamelanotide) is 75921-69-6. It is a synthetic analog of alpha-MSH.

What purity does Melanotan 1 achieve?

Batch 5666 tested at 98.82% purity by independent HPLC at an independent third-party laboratory.

How does Melanotan 1 differ from Melanotan 2 in research?

Melanotan 1 is a linear 13-amino acid peptide (vs. MT-2 which is a cyclic 7-amino acid peptide). MT-1 is more selective for the MC1R receptor, while MT-2 has broader melanocortin receptor activity in research models.
