Research Background
Melanotan II is a cyclic heptapeptide analogue of α-melanocyte-stimulating hormone. It is a broadly acting melanocortin receptor agonist used in receptor-pharmacology research, and its lactam-bridged cyclic structure is the reason it appears in structure–activity studies of α-MSH analogues alongside the linear analogue Melanotan I.
