Research Overview

PT-141 (Bremelanotide) is a synthetic 7-amino-acid cyclic analog of α-MSH and a non-selective agonist of the melanocortin receptors, with notable activity at MC3R and MC4R. It is studied in research models of central nervous system signaling and melanocortin pharmacology.

Mechanism of Action

Engages MC3R and MC4R in central nervous system tissue in research models, influencing downstream cAMP-mediated signaling cascades.

Research Applications

  • Melanocortin receptor pharmacology
  • CNS signaling research
