MT-1(MelanotanI)

MT-1, also catalogued as Melanotan I, in Canada is supplied by Horizon Peptides as a lyophilized powder in sealed 10 mg research vials, available singly or in 3-vial and 10-vial packs. MT-1 is a melanocortin analogue studied in pigmentation pathway research.

MT-1 is the first-generation Melanotan analogue, predating the cyclic compound that followed it. The catalogue records a molecular weight of 1646.8 for the material supplied here.

Its interest as a research tool lies almost entirely in that chronology. When a second-generation compound is developed to address limitations in the first, keeping the original available lets researchers test whether the intended improvement actually shows up in binding data, rather than taking the design rationale on trust.

Studies using it concern melanocortin receptor interaction and melanogenesis pathways in cell-culture systems, generally as one arm of a comparison rather than in isolation.

The second-generation compound is MT-2, also available as a nasal spray. A further member of the melanocortin family stocked here is PT-141.
