MT-1 10mg

MT-1 (Melanotan I) is a synthetic linear peptide analog of alpha-melanocyte-stimulating hormone (α-MSH). Developed as a research tool to study melanocortin receptor signaling, MT-1 has attracted interest for its potent agonist activity at melanocortin 1 receptor (MC1R), making it a valuable compound for investigating pigmentation pathways and melanocyte biology in laboratory models.

MT-1 is a 13-amino-acid peptide (Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2) modified from the native α-MSH sequence to enhance metabolic stability and receptor binding affinity. The Nle4 and D-Phe7 substitutions are key structural modifications that increase resistance to enzymatic degradation while preserving melanocortin receptor agonism. Supplied as 10mg lyophilized peptide for in vitro and preclinical research applications.

MT-1 acts primarily on melanocortin 1 receptor (MC1R), stimulating melanogenesis in melanocytes. Preclinical research has examined its effects on melanogenesis pathways and its interaction with UV radiation exposure models. Early-phase clinical studies investigated melanin production endpoints in response to MT-1. Research has also characterized its binding affinity profile across the broader melanocortin receptor family (MC1-5R).
