About PT-141 Pen

PT-141, also known as Bremelanotide, is a synthetic cyclic-peptide melanocortin-receptor agonist studied for its activity at MC3-R and MC4-R in central nervous system research models. Unlike vasoactive compounds that act on peripheral blood flow, PT-141 has been investigated for centrally mediated pathways relevant to arousal and behavioural research. Supplied as a pre-loaded research pen for in-vitro and preclinical applications.

Research Applications

Research Mechanism — PT-141 Pen

A simplified summary of what PT-141 Pen is studied for in research models. For laboratory in-vitro use only.

Sequence:Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH

Origin: Synthetic cyclic heptapeptide analogue of α-MSH, derived from the Melanotan II scaffold and produced by solid-phase peptide synthesis.

  1. Molecular target

    A cyclic melanocortin-receptor agonist investigated for its binding affinity to central nervous system melanocortin receptors in research models.

    • Melanocortin-4 receptor (MC4-R)
    • Melanocortin-3 receptor (MC3-R)
    • Hypothalamic paraventricular nucleus circuits

  2. Investigated pathways

    Preclinical studies have explored downstream effects on Gαs-coupled cAMP signalling, central neurotransmitter release, and autonomic-response markers in animal research.

    • Gαs-coupled cAMP–PKA signalling
    • Hypothalamic dopamine release studies
    • Oxytocinergic neurocircuit response assays

  3. Preclinical research applications

    Used as a research tool in laboratory models exploring melanocortin neurobiology, central-nervous-system pharmacology, and behavioural-response research. Not approved for human use.

    • Rodent melanocortin receptor binding assays
    • Central nervous system signalling models
    • Behavioural neuroscience research studies

For research use only. PT-141 Pen is not approved as a medicine in the UK and is not intended for human or veterinary administration. See the compliance page for full terms.
