PT-141

Melanocortin-receptor-agonist peptide (bremelanotide)

PT-141, also known as bremelanotide, is a synthetic peptide that acts on melanocortin receptors. In the scientific literature it appears in melanocortin-signaling research models. This page provides neutral background about the molecule as a research material and is not medical guidance and not for human or veterinary use.

Classification and structure

Classification and structure: PT-141 is a cyclic heptapeptide structurally related to the melanocortin family and is a metabolite-derived analog within that lineage. It is studied as an agonist at melanocortin receptors, with particular attention in the literature to receptor subtype interactions. Describing a compound as 'studied in' an area is a statement about where scientific attention has gone, not a claim that it produces any result.

Areas of research

PT-141 appears in several defined areas of the research literature.

• Melanocortin signaling — Investigated in models of melanocortin receptor agonism and downstream pathways.
• Neuroendocrine research — Appears in the literature on centrally mediated melanocortin signaling models.
• Peptide pharmacology — Studied in structure-activity comparisons within the melanocortin class.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.
