Description
Melanotan I Peptide (MT-1)
THIS IS NOT FOR HUMAN CONSUMPTION. SOLD FOR RESEARCH ONLY!
Melanotan I Peptide Details
Melanotan I (afamelanotide precursor research form) is a synthetic linear analog of alpha-melanocyte-stimulating hormone (α-MSH), engineered — unlike the more broadly acting cyclic analog Melanotan II — to act more selectively at the MC1R (melanocortin-1 receptor) responsible for melanogenesis, with reduced activity at the MC4R pathway associated with appetite and sexual-behavior effects. This improved selectivity profile is the basis of Melanotan I's research relevance: because MC1R activation stimulates eumelanin production in skin melanocytes, the compound has been studied for photoprotective and pigmentation research, including its developed pharmaceutical form (afamelanotide, marketed as Scenesse) used clinically for erythropoietic protoporphyria, a rare photosensitivity condition. Melanotan I's relatively selective MC1R activity — compared to the non-selective activity of Melanotan II — continues to make it the preferred research compound for studies specifically examining melanocortin-driven pigmentation pathways.
About Melanotan I Scientific Research
- Melanocortin Receptor Pharmacology
Used in in-vitro cell assays to measure receptor binding and activation across melanocortin receptor subtypes. MT1 supports receptor selectivity comparisons and is frequently paired with signaling reporters like cAMP and PKA-activated transcription factors. - Pigmentation Biology and Melanocyte Models
MT1 is ideal for studying MC1R-mediated melanin production. Research focuses on transcriptional activation of melanogenesis enzymes (e.g., tyrosinase) and analysis of melanosome formation and function in cultured melanocytes. - Neuroendocrine and Neuroimmune Signaling
Research involving CNS tissues or rodent models uses MT1 to examine neurotrophic gene expression, BDNF regulation, and receptor-linked plasticity pathways. MT1 also serves as a tool in inflammation-linked neurobiology research. - Cardiovascular and Autonomic Regulation
In preclinical cardiovascular studies, Melanotan 1 has been used to assess its impact on autonomic balance, blood pressure regulation, and endothelial function via MC receptor signaling. - Energy Metabolism and Metabolic Pathway Probing
Due to MC4R’s role in energy homeostasis, MT1 is used in animal studies to assess receptor-linked regulation of lipid metabolism, substrate oxidation, and body-weight regulation under experimental diets or stressors.
