Melanotan II

Melanotan II is a synthetic cyclic heptapeptide analogue of α-melanocyte-stimulating hormone investigated in research for its interaction with melanocortin receptor pathways. It is studied for its potential to influence melanogenesis (the production of melanin pigment in skin cells) and for its activity at related receptors involved in appetite regulation and neurobehavioural signalling. In laboratory settings, Melanotan II is examined as a model compound for exploring melanocortin system functions and receptor-specific responses.
