MT-1 (Melanotan 1, also called afamelanotide) is a synthetic 13-amino-acid analog of alpha-melanocyte-stimulating hormone (alpha-MSH) that selectively activates melanocortin-1 (MC1R) and to a lesser extent MC4R receptors. In research it is studied for melanocyte signaling, pigmentation pathway research, and photoprotection model systems. Supplied strictly for Research Use Only.
MT-1 is more selective for the MC1R receptor (the pigmentation pathway). MT-2 activates a broader range of melanocortin receptors including MC4R. The selectivity difference produces different research profiles in published literature studying central versus peripheral melanocortin pathways.
MT-1 is studied in preclinical research on melanocortin receptor signaling, melanin synthesis pathways, photoprotection model systems, and ultraviolet response research. All cited studies are conducted in cellular or rodent systems consistent with RUO classification.
