PT-141 (Bremelanotide)

Also known as Bremelanotide

PT-141 is a cyclic heptapeptide and the deaminated metabolite of melanotan II, acting as an agonist at melanocortin receptors with principal research interest at MC4R. Unlike melanotan II it lacks significant MC1R-mediated pigmentation activity, making it a cleaner tool for isolating MC4R-mediated central effects. Its mechanism is centrally mediated rather than vascular, which distinguishes it from PDE5-targeting compounds.

Research applications

  • MC4R and MC3R binding and selectivity assays
  • Central melanocortin pathway signaling studies
  • Comparative receptor profiling against melanotan II

Storage
