Melanotan-2
What is Melanotan-II?
Melanotan-II (MT-II) is a synthetic peptide analog of α-melanocyte-stimulating hormone (α-MSH) studied for its interaction with melanocortin receptors. In laboratory and preclinical research settings, MT-II has been examined for its role in melanin production, pigmentation signaling, appetite regulation, and central nervous system pathways.
Due to its receptor-mediated activity across melanocortin pathways, Melanotan-II is a compound of interest in pigmentation and neuroendocrine research models.

Melanotan-II Overview
Melanotan-II is a cyclic peptide derived from α-MSH, designed to study melanocortin receptor activation, particularly MC1R, MC3R, MC4R, and MC5R. In research models, MT-II has been investigated for its influence on melanogenesis, pigmentation pathways, appetite signaling, and neurobehavioral responses.
- Melanocortin receptor activation (MC1R, MC3R, MC4R, MC5R)
- Melanogenesis and pigmentation pathway signaling
- Appetite, energy-balance, and neuroendocrine research models
Ongoing research explores its role in hormone-mediated signaling and receptor-specific activity across dermatological and central pathways.
Hadley M.E. & Haskell-Luevano C., 1999History and Development
Melanotan-II emerged from early research into melanocortin biology and the physiological roles of α-MSH. Initial studies focused on pigmentation signaling and UV-induced melanogenesis.
Subsequent research expanded into central melanocortin pathways, examining MT-II’s interactions with receptors involved in energy balance, neuroendocrine regulation, and behavior. Its defined cyclic structure has made it a recurring compound in experimental models of receptor signaling.
