Research Overview
PT-141 (bremelanotide) is a synthetic cyclic heptapeptide derived from Melanotan 2 and acting as a
melanocortin receptor agonist.
In experimental systems it is used to explore central MC4R/MC1R signaling, sexual function models, appetite control and
vascular or circulatory responses under different stressors.
Primary Research Areas
-
Melanocortin receptor signaling:
MC4R/MC1R agonist used in studies of hypothalamic and CNS melanocortin pathways.
-
Sexual function & arousal models:
experimental paradigms assessing centrally mediated sexual behaviour and neuroendocrine responses.
-
Appetite & energy-balance research:
models investigating feeding behaviour, caloric intake and weight-regulation pathways via melanocortin signaling.
-
Inflammatory & circulatory responses:
studies exploring vascular tone, blood-flow changes and inflammatory markers in response to MC receptor activation.
