MELANOTAN II
Summary
Melanotan II is one of the most studied peptides in the field of pigmentation and the melanocortin system: it is researched for its role in melanogenesis (melanin production) and melanocortin receptor biology. Technically, it is a cyclic synthetic α-MSH analog and a non-selective agonist of melanocortin receptors (MC1R, MC3R, MC4R, and MC5R).
What is it researched for?
- • Melanogenesis and skin pigmentation
- • UV radiation-independent photoprotection
- • Melanocortin receptor biology
- • Central signaling via MC4R
Cycle and rest
Mechanism of action
Melanogenesis via MC1R
Activation of the MC1R receptor in melanocytes stimulates eumelanin synthesis, which is the basis for its study in skin pigmentation and photoprotection.
Melanocortin system (MC4R)
As a non-selective agonist, it also acts on MC4R, a pathway involved in appetite regulation and sexual function.
Research in pigmentation
It is researched in the context of pigmentation, photoprotection, and the biology of various melanocortin receptors.
Scientific evidence
Melanogenesis: Studies describe an increase in MC1R-mediated melanogenesis, independent of UV radiation exposure.
Melanocortin system: Preclinical models document effects on the central melanocortin system.
Receptor affinity: Literature describes its affinity for multiple melanocortin receptor subtypes.
