Melanotan-1, also known in literature as Melanotan I or afamelanotide, is a linear alpha-MSH analogue. It is usually discussed around MC1R-associated signalling, pigmentation pathway models, receptor selectivity, and peptide analogue stability.
The important comparison is structure. Melanotan-1 is a linear melanocortin analogue, while Melanotan II and PT-141 are cyclic analogues. That makes Melanotan-1 useful when the study focus is how sequence design changes melanocortin receptor behaviour.
