Melanotan 1

Origin & Classification

Melanotan 1, also known as afamelanotide, is a 13-amino-acid analog of the endogenous peptide alpha-melanocyte-stimulating hormone (alpha-MSH). It includes sequence modifications that increase stability and potency, such as substitution at the seventh position and N-terminal acetylation. This analog is produced via solid-phase peptide synthesis and belongs to the class of melanocortin receptor agonists.

Mechanism & Research Context

Melanotan 1 binds to melanocortin 1 receptor (MC1R) with high affinity, activating adenylate cyclase, elevating cAMP, and triggering downstream pathways that enhance eumelanin production in melanocytes. Researchers employ Melanotan 1 to study pigmentation biology, photoprotective responses to ultraviolet radiation, and the regulation of melanogenic enzymes such as tyrosinase. Beyond pigmentation, MC1R signaling is also involved in inflammatory modulation, oxidative stress responses, and DNA repair mechanisms; thus, Melanotan 1 is used as a tool to explore these pathways. Studies examine cross-talk with POMC-derived peptides, MC4R signaling, and interactions with p53 and DNA damage response networks, focusing on mechanistic insights rather than clinical outcomes.

Composition & Quality

Melanotan 1 is supplied as a lyophilized peptide with purity typically exceeding 95 % as determined by HPLC and mass spectrometry. Production aligns with GMP standards, including stepwise peptide synthesis, purification, and sterile filtration. Quality control measures involve analysis of peptide content, identification of impurities, and endotoxin testing. Stability data support storage of lyophilized material under refrigeration, and reconstituted solutions should be protected from repeated freeze-thaw cycles. Certificates of analysis accompany each batch, detailing sequence, purity, and recommended handling.
