Comment: Setmelanotide is an agonist of melanocortin receptors, with approximately 20-fold selectivity for the melanocortin 4 receptor subtype [5]. Chemically it is an eight-amino-acid cyclic peptide, that is able to cross the blood-brain barrier when administered peripherally. Setmelanotide offers anti-obesity potential.
The INN record documents the sequence as N2-acetyl-L-arginyl-L-cysteinyl-D-alanyl-L-histidyl-D-phenylalanyl-L-arginyl-L-tryptophyl-L-cysteinamide, cyclic (2-8)-disulfide.
