Melanotan 2 is a synthetic analogue of the endogenous peptide alpha-melanocyte-stimulating hormone (α-MSH), cyclized to enhance metabolic stability. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only. Research ContextMelanotan 2 is studied as a non-selective agonist at melanocortin receptors (MC1R, MC3R, MC4R, and MC5R) in in-vitro and animal-model research. MC1R signalling is a subject of melanogenesis pathway research, while MC3R and MC4R engagement is investigated in studies of central melanocortin signalling and energy-homeostasis pathways. Its cyclized structure confers greater receptor binding affinity and resistance to enzymatic degradation compared to native α-MSH, making it a widely used tool compound in melanocortin system research.
