Description
MELANOTAN 2
For Research Use Only | Not for Human or Veterinary Use
Description:
Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH), originally developed at the University of Arizona. In preclinical laboratory research, Melanotan II has been extensively investigated for its activity at melanocortin receptors (MC1R through MC5R), with particular affinity for MC1R, MC3R, MC4R, and MC5R. The compound’s cyclic lactam structure confers enhanced metabolic stability compared to the linear endogenous ligand, making it a widely used pharmacological tool in melanocortin signaling research, pigmentation biology, and studies of energy homeostasis and sexual function pathways.
