About PT-141

PT-141 (bremelanotide) is a synthetic cyclic heptapeptide derived from Melanotan II. It differs from Melanotan II by a free carboxylic-acid C-terminus in place of the amide, and is studied as a melanocortin-receptor agonist with activity at MC4R and MC3R.

Researchers use PT-141 as a reference ligand in melanocortin-receptor binding and cAMP assays and in studies of central MC4R signalling pathways. Port Peptides PT-141 will be supplied at 10mg as a lyophilised research peptide.

Research applications

  • MC3R / MC4R receptor binding and cAMP assays
  • Central melanocortin signalling research
  • Structure–activity comparisons with Melanotan II
  • Hypothalamic neuropeptide pathway models

Mechanism studied

Melanocortin-receptor agonist studied primarily at MC4R and MC3R, with lower melanogenic activity than Melanotan II in laboratory models.

Also known as: Bremelanotide, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH, CAS 189691-06-3.
