Mechanism
Melanotan II is a conformationally constrained cyclic lactam heptapeptide. It retains the conserved His-Phe-Arg-Trp core motif, with three engineered modifications relative to the parent linear sequence: substitution of methionine by norleucine, inversion of L-phenylalanine to D-phenylalanine, and a side-chain-to-side-chain lactam bridge (Asp–Lys) that locks the backbone into a defined turn conformation. These changes are associated with reduced susceptibility to enzymatic cleavage in vitro and constrain the bioactive conformation. The constrained scaffold is widely used as a reference ligand for characterizing the binding and selectivity profile of class A (rhodopsin-like) G-protein-coupled receptors in radioligand and structural-biology studies.
