Melanotan II (MT-II) Cyclic Melanocortin Receptor Agonist Analogue | Research Use Only

Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH), developed as a more metabolically stable and potent melanocortin receptor agonist. Structural modifications, including cyclization, incorporation of D-phenylalanine, and an acetylated N-terminus, confer resistance to enzymatic degradation and enhanced receptor binding relative to native α-MSH.

Melanotan II acts as a non-selective agonist across multiple melanocortin receptor subtypes (MC1R, MC3R, MC4R, MC5R) and has been extensively utilized in preclinical research examining melanocortin system pharmacology. Research applications include melanogenesis and pigmentation biology studies, hypothalamic MC4R signaling investigations, appetite and energy homeostasis models, cardiovascular biology research, and neuroprotective pathway studies. It serves as a widely used pharmacological tool in studies characterizing melanocortin receptor subtype selectivity and downstream signaling mechanisms.
