About PT-141
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide and a non-selective agonist of melanocortin receptors. Structurally a metabolite of Melanotan II lacking the C-terminal amide functionality, it exhibits significantly reduced affinity for the MC1 receptor and is utilised in research investigating melanocortin receptor signalling pathways.
Primary areas of investigation
- MC3R/MC4R receptor signalling
- Melanocortin pathway research
- Hypothalamic cell line studies
- Dopamine signalling investigation
- Central neural pathway research
- Cyclic peptide stability models
Mechanism
Research into PT-141 examines its activation of central melanocortin receptors, specifically MC3R and MC4R, in hypothalamic cell models. In experimental systems, it is investigated for its interaction with dopamine signalling pathways and neural signalling research, distinct from vascular-mediated pathways. Studies focus on receptor binding dynamics under controlled laboratory conditions.
