Melanotan-II (MT-2) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). MT-2 exhibits broad-spectrum melanocortin receptor (MCR) binding affinity across MC1R through MC5R subtypes. It is studied in vitro for melanocortin receptor activation kinetics, cAMP signaling cascades, and downstream MAPK/ERK pathway modulation in cell-based assays. For in vitro research use only. Not for human or veterinary use.
