What is PT-141?

PT-141 is a synthetic peptide analog of alpha-melanocyte–stimulating hormone (α-MSH). It is intended for laboratory investigation of melanocortin receptor interaction and associated intracellular signaling pathways in controlled research environments.

Mechanism of Research Interest

PT-141 is examined in vitro and in non-clinical models for its interaction with melanocortin receptors, including MC3R and MC4R. Research may include evaluation of receptor-binding characteristics, signal transduction activity, and peptide stability under experimental conditions.

Why Researchers Study PT-141

  • To analyze melanocortin receptor-binding activity in laboratory assays
  • To evaluate intracellular signaling responses in controlled experimental models
  • To examine structural and biochemical characteristics under research conditions

Research Background

PT-141 (Bremelanotide) (PT-141) is a synthetic peptide analog of alpha-MSH and a metabolite of Melanotan II. PT-141 has been investigated in laboratory research for its selective interaction with melanocortin-4 receptor (MC4R) signaling pathways in preclinical experimental models.

Laboratory Research Areas

In published scientific literature, PT-141 has been explored in the following research contexts:

  • MC4R binding selectivity and activation in receptor assays
  • Melanocortin pathway signaling characterization in in vitro models
  • Comparative analysis with other melanocortin receptor ligands
  • Peptide metabolite stability and structural characterization
