Afamelanotide
Afamelanotide is a first-in-class, synthetic, 13-amino acid peptide analogue of the endogenous alpha melanocyte-stimulating hormone (α-MSH). It differs structurally from its endogenous counterpart by only two amino acids – these structural differences improve biological efficacy by imparting a greater affinity for its target and a longer biological half-life.
